Double switch case not working properly. Google maps shapes drawing - google-maps

I would like to create popup menu which includes: choosing maptypes, choosing shape with citywalls drawn on map.
My problems:
I have no idea how to clean once picked shape (or switch it to none, method doesnt matter)
How to make my map not to be loaded again when i change shape.
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch(item.getItemId()){
case R.id.mediewal:
shape = new PolygonOptions();
mMap.addPolygon(shape);
break;
case R.id.swedish:
shape = new PolygonOptions()
.add(new LatLng(53.426685, 14.565516),
new LatLng(53.427519, 14.565268),
................................
new LatLng(53.427003, 14.565636))
.strokeColor(0xB3A60307)
.fillColor(0xB3670000)
.strokeWidth(8)
.geodesic(true);
mMap.addPolygon(shape);
shape = new PolygonOptions()
.add(new LatLng(53.420158, 14.557578),
new LatLng(53.420285, 14.557832),
................................
new LatLng(53.419972, 14.557818))
.strokeColor(0xB3A60307)
.fillColor(0xB3670000)
.strokeWidth(8)
.geodesic(true);
mMap.addPolygon(shape);
break;
case R.id.prussian:
shape = new PolygonOptions();
mMap.addPolygon(shape);
break;
case R.id.none:
shape = new PolygonOptions();
mMap.addPolygon(shape);
break;
}
switch(item.getItemId()){
case R.id.normal_map:
mapType = GoogleMap.MAP_TYPE_NORMAL;
break;
case R.id.satellite_map:
mapType = GoogleMap.MAP_TYPE_SATELLITE;
break;
case R.id.terrain_map:
mapType = GoogleMap.MAP_TYPE_TERRAIN;
break;
case R.id.hybrid_map:
mapType = GoogleMap.MAP_TYPE_HYBRID;
break;
}
mMap.setMapType(mapType);
return super.onOptionsItemSelected(item);
}
Of course Ive put only one test shape here. Currently its working like this: I can pick maptype and pick shape, but no way to clean shape in another way than going out to menu and go maps again.
Any help would be greatly appreciated

Generaly to avoid loading map over and over again I've moved mMap.setMapType(mapType);under every map type in switch case with mapTypes. Removed ofc this one from Return call.
To clen up shapes I call mMap.clear() which deletes all shapes and markers from map. Its not perfect solution for everybody, but for my case it's enough.
I think to clen up one shape we should call (with checkbox):
if(item.isChecked()){
item.setChecked(false);
polygon2.remove()
;}
else{
item.setChecked(true);
polygon2 = mMap.addPolygon(shape2);
}
break;
Remember to initialize shape e.g. private Polygon polygon2;

Nested movieclips; changing background frame

Where have all my children gone?
Hope this is a relatively simple answer to a less-than-intelligent question that's a consequence of how I learn things when not doing them for work. In this case I started a game about 3 years ago in AS3 as I was familiar with js at least and had also worked with shockwave back in the day. Anyway, when learning something offline like this I tend to learn just what I need to know to do what I need to do next, and can sometimes get pretty far into one area while missing something obvious and simple because I just haven't crossed that case yet.
We have a playing field and playing pieces. Those playing pieces (sailing ships) you see below are complex objects with dozens of properties and several children including graphics and text fields that change depending on the state of the ship. It's WEGO where each side plots moves, those moves are then executed one ship at a time alternatively between the two sides, then we have gun combat, etc. All that is there and works fine, a few thousand lines of code.
My current problem is that when a player clicks on a ship to select it, I unhide a yellow border to indicate which ship is selected and draw the complex ship detail screen you see top left, but for a long time I've wanted to change the background color of the playing piece as well.
After a long layoff I started working on this again and decided to start there. So I made new counters, added them as keyframes to the already existing symbol/class that contains all of the country default backgrounds, and modified the code. It works fine in that the background is changed to the correct highlighted version, and then goes back to default when deselected.
In the image the currently-selected ship is in the center, USS Constitution, its detail/info screen is also displayed. You can see the problem, all the children are gone on the playing piece. And they don't come back when you go back to the original default background.
At first I thought it was a z order problem but it isn't, I walked the selected ship playing piece background in the z index until they disappeared behind the ocean background, there was just open ocean where the ship playing piece used to be.
My best guess is that maybe the children have to be instanced on each frame of the parent's timeline each time you change the parent's frame but if so I'm not finding reference to or explanation of that. That and that seems really unwieldy way of doing things, I was completely caught off guard by the idea of the children caring what frame its parent is on unless there was coded logic telling it to.
Somehow even though I have thousands of lines of complex dialogs and screens displaying multiple dynamic children I have never changed the base background in any of those cases.
Also tried to google this, but had little luck. I couldn't even figure out a relatively simple question to ask.
I'll be happy to paste code but I don't seem to have a code problem but an understanding problem.
Example-selected ship with highlighted background graphic is in the center
For those who feel the code is important, this is the end of the 1500 line ship-creation function where most of the children get added:
textShipSailSpeed.name = "textShipSailSpeed";
textShipSailSpeed.width = 20;
textShipSailSpeed.height = 13;
textShipSailSpeed.x = 33;
textShipSailSpeed.y = 14;
textShipSailSpeed.embedFonts = true;
textShipSailSpeed.textColor = 0xFFFFFF;
textShipSailSpeed.rotation -= 90;
//full sails set
if ("full" == finalShip.sailState) {
textShipSailSpeed.text = finalShip.fullSailSpeed;
}
//battle sails set, which are reduced sails to improve visibility and reduce sail damage in combat
else {
textShipSailSpeed.text = finalShip.battleSailSpeed;
}
// textShipBattleSailSpeed and textShipFullSailSpeed no longer used on counters, but still used in Info screens
var textShipBattleSailSpeed: TextField = new TextField();
textShipBattleSailSpeed.name = "textShipBattleSailSpeed";
textShipBattleSailSpeed.text = finalShip.battleSailSpeed;
textShipBattleSailSpeed.visible = false;
var textShipFullSailSpeed: TextField = new TextField();
textShipFullSailSpeed.name = "textShipFullSailSpeed";
textShipFullSailSpeed.text = finalShip.fullSailSpeed;
textShipFullSailSpeed.visible = false;
//create sailState (battle/full) indicator
var sailStateIndicator: WSIM_Counters_SailtState_Indicator = new WSIM_Counters_SailtState_Indicator();
//set indicator to correct sailState background graphic
sailStateIndicator.gotoAndStop("battle");
if ("full" == finalShip.sailState) {
sailStateIndicator.gotoAndStop("full");
}
finalShip.addChild(sailStateIndicator);
//add ship and attach text fields
gridBG1.addChild(finalShip);
finalShip.addChild(textShipName);
finalShip.addChild(textShipSailSpeed);
finalShip.addChild(textShipTurnAllowance);
finalShip.addChild(textShipBattleSailSpeed);
finalShip.addChild(textShipFullSailSpeed);
finalShip.parent.setChildIndex(finalShip, 1);
//logging
if (log_shipCreation) {
trace(finalShip.name + " added added as child of background in createShip()");
}
//create background sprite "ship is selected" border
var border: Sprite = new Sprite();
border.name = "shipBorder";
border.graphics.beginFill(0xFFCC00, 1);
border.graphics.drawRect(-1, -1, 52, 132)
border.graphics.endFill();
border.visible = false;
//create background sprite combat border
var borderCombat: Sprite = new Sprite();
borderCombat.name = "borderCombat";
borderCombat.graphics.beginFill(0xFF0000, 1);
borderCombat.graphics.drawRect(-1, -1, 52, 132)
borderCombat.graphics.endFill();
borderCombat.visible = false;
//add the borders as children of ship
finalShip.addChild(border);
finalShip.addChild(borderCombat);
//move the borders in z-order to behind ship counter, so they show looking like a border
border.parent.setChildIndex(border, border.parent.getChildIndex(border) - 5);
borderCombat.parent.setChildIndex(borderCombat, borderCombat.parent.getChildIndex(borderCombat) - 6);
//PUSH TO MASTER SHIP ARRAYS
//finalShip is Side 1, add to master list of ship objects for Side 1
if (sideList[0] == finalShip.country) { ....
And this is part of the even larger selectShip function, here is where I clear the selected state on all ships on map and then set the current ship's background to currShip.country+"_sel" which is the correct frame label for the "selected" background images.
//clear combat selected state on all ships
for (var i: int = 0; i < shipListSide1.length; i++) {
//hide selection border sprite and set select property false
shipListSide1[i].combatSelected = false;
var borderChildCombat = shipListSide1[i].getChildByName("borderCombat");
borderChildCombat.visible = false;
//show default counter background, build label name
shipListSide1[i].gotoAndStop(shipListSide1[i].country+"_def");
}
for (var i: int = 0; i < shipListSide2.length; i++) {
//hide selection border sprite and set select property false
shipListSide2[i].combatSelected = false;
var borderChildCombat2 = shipListSide2[i].getChildByName("borderCombat");
borderChildCombat2.visible = false;
//show default counter background, build label name
shipListSide2[i].gotoAndStop(shipListSide2[i].country+"_def");
}
//check to see if this is selecting a target in gun combat
if ((false == currShip.side1 && enableCombatSelectSide2) || (currShip.side1 && enableCombatSelectSide1)) {
combatSelectShip(currShip);
}
//we're allowed to select this ship
if ((enableSelectSide1 && currShip.side1) || (enableSelectSide2 && false == currShip.side1)) {
//event is from a ship object
if (currShip is Ship_1) {
//remove previous ship info screen
if (currShipInfo.parent) {
currShipInfo.parent.removeChild(currShipInfo);
}
//clear selected state on all ships
for (var i: int = 0; i < shipListSide1.length; i++) {
//hide selection border sprite and set select property false
shipListSide1[i].selected = false;
var borderChild = shipListSide1[i].getChildByName("shipBorder");
borderChild.visible = false;
//default graphic already set in clearing combatselect status above
}
for (var i: int = 0; i < shipListSide2.length; i++) {
//hide selection border sprite and set select property false
shipListSide2[i].selected = false;
var borderChild2 = shipListSide2[i].getChildByName("shipBorder");
borderChild2.visible = false;
//default graphic already set in clearing combatselect status above
}
//Change graphic of selected ship to selected, highlighted color
currShip.gotoAndStop(currShip.country+"_sel");
//set selected state on clicked ship, unhide border
currShip.selected = true;
borderChild = currShip.getChildByName("shipBorder");
borderChild.visible = true;
Ok based on feedback about it being a z-order issue, the below is what I tried to move the missing children back above the playing piece background. If you notice it also has to be a z order issue as the "selected" border, which is a child of the playing piece like the missing ones, that happens to purposely be behind the playing piece graphic, displays correctly when the ship is in the selected state. See the original screenshot, the playing piece in the center that's selected and is missing its children also has a yellow border.
Anyway, below is what I tried. It works in that there are no errors but I really couldn't find these children in the debugger to confirm what happened, and so far I at least appear to have moved them up in the z order to the max before I get an out of range error, and the problem still exists - no ship graphic, ship name, movement allowance, etc.
//Change playing piece background of the selected ship to selected, highlighted color frame
currShip.gotoAndStop(currShip.country+"_sel");
//trying to move the children of the playing piece back above the playing piece graphic
var shipChildrenArray:Array = new Array("textShipName","textShipTurnAllowance","textShipSailSpeed","sailStateIndicator");
for each(var childItem:String in shipChildrenArray) {
currShip.setChildIndex(currShip.getChildByName(childItem), 3);
}
Your parent movieclip should have layers. The child movieclip that you want to always be visible needs to extend across all frames of the parent.
Note that I did not see what you say I should be able to see on your graphic. Since I don't know what you think it should look like, I wasn't able to spot the difference between what it does look like and that.
You may find you get better feedback if you post a screen capture of the timeline and post any code that's involved.
I try to build a simple replica of your hierarchy here:
package {
import flash.display.MovieClip;
import flash.events.*;
public class gameTestDoc extends MovieClip {
var pieceArray:Array = new Array();
public function gameTestDoc() {
stage.addEventListener(MouseEvent.CLICK, selectPiece);
for (var i:int = 0; i < 4; i++){ // creates 4 instances of a class with 6 frames, each having a different colored rectangle.
var gamePiece:MovieClip = new backGround();
addChild(gamePiece);
gamePiece.x = 50 * i + 200; // space out the game pieces.
gamePiece.y = stage.stageHeight/2; // center game pieces.
pieceArray.push(gamePiece);// add piece to array.
for (var j:int = 0; j < 5; j++){
var components:MovieClip = new MovieClip();
components.graphics.lineStyle();
components.graphics.beginFill(0x00ffcc * j * 200000); //gives different color to each component.
components.graphics.drawRect(0,0,5, 10);
components.graphics.endFill();
gamePiece.addChild(components);
components.y = j * 5;
}
gamePiece.gotoAndStop(Math.ceil(Math.random()*10)); // give each piece a random frame to go to.
}
}
function selectPiece(e:MouseEvent):void{ // sends game piece frame to random frame.
for (var i:int = 0; i < pieceArray.length; i++){
e.target.gotoAndStop(Math.ceil(Math.random()*10));
}
}
}
}
and I have an mc in the GUI library with the linkage name of "backGround". When I click on the pieces, the backgrounds change color, and everything else stays on top. Here is a picture:
and after I click the 2nd piece:
can you see from my simple code what you might be doing differently?
edit: 6-10-16
//move the borders in z-order to behind ship counter, so they show looking like a border
border.parent.setChildIndex(border, border.parent.getChildIndex(border) - 5);
borderCombat.parent.setChildIndex(borderCombat, borderCombat.parent.getChildIndex(borderCombat) - 6);
wouldn't this be less confusing/prone to strange behavior?:
//move the borders in z-order to behind ship counter, so they show looking like a border
border.parent.setChildIndex(border, 0);
borderCombat.parent.setChildIndex(borderCombat, 0);
Would this not give the same result?
At first I thought it was a z order problem but it isn't,
Actually this is probably exactly your problem.
I walked the selected ship playing piece background in the z index until they disappeared behind the ocean
Really? How? Moving the z-order of display objects in a container can't change the z-order of the container. But if you are moving the ship itself (the container of all your other symbols), then yes, the open ocean will appear. But just shifting things around within the ship won't do that. How to shift things around in the ship container? Go here.
Example
If your game piece (pieceMc) is a child of the ocean background (oceanMc) and the the flag background (flagMc) is a child of the piece then
oceanMc.gamePieceMc.setChildIndex(flagMc,0);
should put the flag to the bottom
Edit 6/11/16
One quick and dirty way to change z-order at runtime is to re add the child; it will be put on top of the stack. You could do
piece[i].addChild(ship);
piece[i].addChild(guns);
piece[i].addChild(nameField);
the result will be that the ship will come to the top, then the guns will be put back on top of that, then the nameField on top of that. If the flag background is also a child of "piece" it will below, like you want.
One quick and dirty way to change z-order at runtime is to re add the child; it will be put on top of the stack. You could do piece[1].addChild(ship); piece[1].addChild(guns); piece[1].addChild(nameField); the result will be that the ship will come to the top, then the guns will be put back on top of that, then the nameField on top of that. If the flag background is also a child of "piece" it will below, like you want. – Neal Davis yesterday
Ok, this is the closest to the correct answer I'm going with. As you can see in the update to my original question, I tried to fix the z order problem by either moving the children up or the background down, but had no luck even though the code executes fine.
So I changed my solution to this:
//Change playing piece background of the selected ship to selected, highlighted color frame
currShip.gotoAndStop(currShip.country+"_sel");
//move the children of the playing piece back above the playing piece graphic. When parent changes frame as above it goes to the top of the z order for some stupid reason
var shipChildrenArray:Array = new Array("textShipName","textShipTurnAllowance","textShipSailSpeed","sailStateIndicator", "currShipGraphic");
for each(var childItem:String in shipChildrenArray) {
//currShip.setChildIndex(currShip.getChildByName(childItem), 5);
var childObject = currShip.getChildByName(childItem);
currShip.removeChild(childObject);
currShip.addChild(childObject);
}
It seems very hacky to me, I'd rather correctly manipulate the z order but unless someone has other ideas on how to do that, we'll have to go with this solution. Re-adding the children does indeed move them back to the top of the current z order array.
So:
1) If you have nested movieclips and you change the frame of the parent, it will go to the top of the z order array for reasons I can't begin to fathom. I don't see a way to prevent it either.
2) If you know how to manipulate the z order of the child movieclips better than I do, that would probably be the best solution.
3) A sledgehammer solution is removing and adding all the children back.
...and it won't let me post a screenshot of it working properly because I "need at least 10 reputation points to post more than two links." Makes no sense as this attachment is the SECOND link, not third or more. Oh well.
Responding to Neal's post.
Looking at the code, only difference that I see is that you're adding the pieces as children of the stage, while mine are one nested level down by being children of the ocean graphic.
Since you're interested and spending time with it, I'll post the entire ship creation function below. It gets called iteratively and loops through the side1 master array of ships and then side2, back to back. That's one reason I'm so confused by the two sides' z orders being consistently different, maybe alphabetical is being applied- only z order manipulation I do in the creation is pushing the border children (one normal select one combat) behind the playing piece.
BTW, please also look for another question from me involving a different issue I am having where a dialog is refusing to disappear on removeChild even though the associated code hasn't been touched in a couple years.
This is ship creation. This is a simulation, not a game, so it's reasonably complex with large numbers of properties set. One somewhat unusual thing I do you will see is cast my Ship_1 classes to a generic object to set all the custom properties and then back to Ship_1 once that's done. I always thought that was a little risky but have seen zero problems (unless this issue is tied to that somehow)
//create ship objects, set properties, add to core arrays
function createShip(currShip) {
// create Ship_1 obj and cast it temporarily as parent class (which is dynamic) to set custom properties

How could i make an array of removed tiles?

So i have a procedural generated game that loads in chunks, i need a way for my code to remember if i cut down a tree or broke a rock so it doesnt replace it when leaving and entering a new area. I got it almost working except instead of putting them back in the correct place, it moves them to fill in the blanks. (if that makes since)
this is the slimmed down function of what adds the removed tiles to my array of removed tiles
public function removeAndAddTile(tileRemoved:Function, tileAdded:Function, i:int)
{
world.removedTiles.push(world.tilesInWorld[i]);
}
This is what loads after the tiles get placed when entering an area. In other words, whats suppose to be replacing the tiles that have already been destroyed
protected function usedTiles()
{
for (var i:int = world.tilesInWorld.length - 1; i >= 0; --i)
{
for (var c:int = world.removedTiles.length - 1; c >= 0; --c)
{
if (world.tilesInWorld[i].x == world.removedTiles[c].x && world.tilesInWorld[i].y == world.removedTiles[c].y)
{
var ti:String = world.tilesInWorld[i].onTile;
var tx:int = world.removedTiles[c].x;
var ty:int = world.removedTiles[c].y;
world.worldTiles.removeChild(world.tilesInWorld[i]);
switch (ti)
{
case "grass" :
world.tilePool.returnSprite(world.tilesInWorld[i]);
break;
case "stone" :
world.rockPool.returnSprite(world.tilesInWorld[i]);
break;
}
world.tilesInWorld.splice(i, 1);
clicked = true;
switch (ti)
{
case "grass" :
world.tile = world.tilePool.getSprite();
break;
case "stone" :
world.tile = world.stonePool.getSprite();
break;
}
world.tile.width = world.TILE_SIZE;
world.tile.height = world.TILE_SIZE;
world.tile.x = tx;
world.tile.y = ty;
world.tilesInWorld.push(world.tile);
world.worldTiles.addChildAt(world.tile, i);
}
}
}
}
My question simply is, how can i get my tiles to remember when they have been destroyed and to delete and replace those tiles when entering an area?

You could use two layers. One bottom layer for the map surface, and another detail layer contains trees, rocks. When your role moves and new area tiles appear, try to get the new area tiles data and add the trees, rocks to the new tile positions.
//the key may be tileX_tileY, the value will be the object type
//if a rock or a tree been broke,delete detailDic[tileX_tileY]
var detailDic:Dictionary;
When your role moves and enter a new area
var newTiles:Array;//the new appeared tiles
for each (var tile:Tile in newTiles)
{
var key:String = tile.tileX + "_" + tile.tileY;
var objectType:String = detailDic[key];
if (check ojectType is valid)
{
add the wanted tree, rock to target position.
}
}
//here you should remove the trees and rocks that disappear from your map's ViewPort

Lines with easelJS using Ticker

I started learning html5 and easelJS two days ago, and I'm working on a game. Now I ran into some problems of course :)
I know I can draw a line with the code:
var context = canvas.getContext('2d');
context.beginPath();
context.moveTo(100, 150);
context.lineTo(450, 50);
context.stroke();
But as far as I know, you shouldn't mix context with easelJS's Ticker/Stage! I use Ticker to update the stage on certain FPS (update would erase the line in this case anyway right?).
Now what I want is to draw a line in tick method on certain occasions (key press) - BUT i need to draw a line slowly, so the user can see it moving towards the end. When a key gets pressed, some functions are called, and I could set some global variable according to which I would perform line drawing in the tick function …
I figured I could use moveTo/lineTo in a loop and increase coordinates accordingly.
What is the best way to approach this, am I missing something or maybe thinking about it totally wrong?
I checked Drawing a Line in a html5 canvas using EaselJS but he has static coordinates and he doesn't need to see the line moving as well.
I'm looking forward to any suggestions/corrections, thanks!
Drawing a line in easeljs
Check out this rudimentary snake game I made in jsfiddle. Note: you'll need to click into the bottom right window to gain focus and use the arrow keys to control the snake. With easeljs, you'll need to subscribe to the model of using DisplayObjects to construct your game environment. The DisplayObject is the building block for all UI content. In this case, I am using a Shape object which is a child class of DisplayObject, and is used to draw vector content. You'll also want to familiarize yourself with the Graphics class in easeljs. Each shape has a graphics property on which you will make all your drawing api calls.
var line = new createjs.Shape();
line.graphics.setStrokeStyle(3);
line.graphics.beginStroke(color);
line.graphics.moveTo(startX, startY);
startY++;
line.graphics.lineTo(startX, startY);
line.graphics.endStroke();
Updating the stage in real time
In order to achieve the line movement, you will need listen to the "tick" event of Ticker object. In the jsfiddle example, I've added the both the stage as a listener, and a window scoped function where the line drawing will occur.
createjs.Ticker.addEventListener("tick", stage);
createjs.Ticker.addEventListener("tick", tick);
You will also notice I've added a onkeydown listener to the window to set our key modifiers which control the direction of the snake.
window.onkeydown = function(e){
color = createjs.Graphics.getRGB(0xFFFFFF * Math.random(), 1);
switch(e.which){
case 38:
wPressed = false;
ePressed = false;
sPressed = false;
nPressed = true;
break;
case 39:
nPressed = false;
sPressed = false;
wPressed = false;
ePressed = true;
break;
case 40:
wPressed = false;
ePressed = false;
nPressed = false;
sPressed = true;
break;
case 37:
nPressed = false;
sPressed = false;
ePressed = false;
wPressed = true;
break;
}
}
Finally, in the tick function, you will make your drawing calls and update the x/y position based on the current direction. Remember the tick function gets called every frame, based on your current frames per second which is set using this static function.
function tick(){
if(nPressed)
{
line.graphics.setStrokeStyle(3);
line.graphics.beginStroke(color);
line.graphics.moveTo(startX, startY);
startY--;
line.graphics.lineTo(startX, startY);
line.graphics.endStroke();
}
if(ePressed)
{
line.graphics.setStrokeStyle(3);
line.graphics.beginStroke(color);
line.graphics.moveTo(startX, startY);
startX++;
line.graphics.lineTo(startX, startY);
line.graphics.endStroke();
}
if(wPressed)
{
line.graphics.setStrokeStyle(3);
line.graphics.beginStroke(color);
line.graphics.moveTo(startX, startY);
startX--;
line.graphics.lineTo(startX, startY);
line.graphics.endStroke();
}
if(sPressed)
{
line.graphics.setStrokeStyle(3);
line.graphics.beginStroke(color);
line.graphics.moveTo(startX, startY);
startY++;
line.graphics.lineTo(startX, startY);
line.graphics.endStroke();
}
}

Draw route on Windows Phone 8 map as position changes?

Scenario:
I want a user to see a map and their current position. Then, if they click "start", navigation will begin and they'll see their "route" drawn onto the map as their position changes, similar to how some fitness apps work that map out your run/walk. The goal is to do this in real-time as the user's position changes.
Options:
The way I see it, there are two options: 1) use a RouteQuery and Map.AddRoute from the starting position, to the next position (when the position changes), keeping track of the last position, and always drawing a new MapRoute from that position to the new, or 2) displaying the user's current position as a dot that moves as their position changes, and then maybe when they press "stop", draw a MapRoute for each of their positions in order to show their full route.
I'd really prefer option #1 because the user can see their route progression, etc., as they go.
Here is the code that I'm using:
XAML:
<maps:Map x:Name="MainMap" />
<Button x:Name="btnStart" Content="Start"/>
<Button x:Name="btnStop" Content="Stop" IsEnabled="False"/>
Code-behind:
Global Variables:
GeoCoordinateWatcher watcher;
List<GeoCoordinate> listCoordinates;
GeoCoordinate lastCoordinate;
btnStart.Tap():
private void btnStart_Tap(object sender, GestureEventArgs e)
{
if (watcher == null)
{
watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.High);
watcher.MovementThreshold = 20;
watcher.StatusChanged += watcher_StatusChanged;
watcher.PositionChanged += watcher_PositionChanged;
}
watcher.Start();
}
watcher.StatusChanged():
private void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
{
switch (e.Status)
{
case GeoPositionStatus.Initializing:
btnStart.IsEnabled = false;
btnStop.IsEnabled = true;
break;
case GeoPositionStatus.NoData:
lblStatus.Text = "location data is not available.";
break;
case GeoPositionStatus.Ready:
lblStatus.Text = "location data is available.";
break;
}
}
watcher.PositionChanged():
void watcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e)
{
if (listCoordinates == null)
{
// first time through:
listCoordinates = new List<GeoCoordinate>();
listCoordinates.Add(e.Position.Location);
lastCoordinate = e.Position.Location;
return;
}
else
{
listCoordinates.Add(e.Position.Location);
DrawRoute(e.Position.Location);
lastCoordinate = e.Position.Location;
}
}
DrawRoute function:
private void DrawRoute(GeoCoordinate newPosition)//
{
RouteQuery query = new RouteQuery()
{
TravelMode = TravelMode.Driving,
Waypoints = new List<GeoCoordinate>() { MainMap.Center, newPosition }
};
query.QueryCompleted += RouteQueryCompleted;
query.QueryAsync();
MainMap.Center = newPosition;
lastCoordinate = newPosition;
}
And finally, RouteQueryCompleted():
void RouteQueryCompleted(object sender, QueryCompletedEventArgs<Route> e)
{
mapRoute = new MapRoute(e.Result);
MainMap.AddRoute(mapRoute);
}
What happens:
It appears to work for a second as I begin driving, a short line is drawn where my start position is, but then about 10 second in, a line is randomly drawn down a nearby street (probably equivalent to 3 or 4 blocks long) and then down another block on a side road (while the whole time I haven't even driven ONE block, let alone make any turns!). It's very bizarre and definitely not accurate. I can upload a screenshot to better illustrate it if need be.
Can anyone see what I'm doing wrong in my code or is there a better way to accomplish this? I wasn't sure if this was the best way but I wasn't able to find any examples suggesting otherwise.
I ended up using MapPolyLine to draw a line between the last GeoCoordinate and the new one.
MapPolyline line = new MapPolyline();
line.StrokeColor = Colors.Blue;
line.StrokeThickness = 15;
line.Path.Add(lastCoordinate);
line.Path.Add(pos);
MainMap.MapElements.Add(line);
I am not sure why you are using RouteQuery for your task. Generally, you use this when you want the map sdk to determine a route for you given a set of coordinates. In your case however, you always know where you are through PositionChanged event. It will be easier to plot directly on the map as you move.
Something like this
void watcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e) {
Plot(e.Position.Location);
}
void Plot(GeoCoordinate pos) {
var ellipse = new Ellipse();
ellipse.Fill = new SolidColorBrush(System.Windows.Media.Colors.Blue);
ellipse.Height = 15;
ellipse.Width = 15;
ellipse.Opacity = 25;
var mapOverlay = new MapOverlay();
mapOverlay.Content = ellipse;
mapOverlay.PositionOrigin = new System.Windows.Point(0.5, 0.5);
mapOverlay.GeoCoordinate = pos;
var mapLayer = new MapLayer();
mapLayer.Add(mapOverlay);
MainMap.Layers.Add(mapLayer);
}

How to check Google map overlay type

Is that possible to check the type of a google map overlay.
var polygon = new G.Polygon();
var rectangle = new G.Rectangle();
var circle = new G.Circle();
var shape;
Now, my code will dynamically assign these overlay to shape variable.
But how can I detect or check the type of an overlay named shape? I can't find the solution using Google.
You can use instanceof, but I'd advise against it. It's not part of the API and could break any time in the future.
It would be better to assign an attribute upon initialization.
var polygon = new G.Polygon();
polygon.type = 'polygon';
var rectangle = new G.Rectangle();
polygon.type = 'rectangle';
var circle = new G.Circle();
polygon.type = 'circle';
console.log(shape.type);
You can check the class via the Javascript instanceof operator:
var polygon = new G.Polygon();
var rectangle = new G.Rectangle();
var circle = new G.Circle();
var shape = selectShape(polygon, rectangle, circle); // your dynamic selection funktion
if (shape instanceof G.Polygon) {
alert("found Polygon");
}
I wrote a function that returns the type of shape it was given. It supports circle and polygon but I'm sure someone can figure out how to add rectangle. It simply checks for unique properties of each.
function typeOfShape(shape){
if(typeof shape.getPath === "function"){
return "polygon";
}else if(typeof shape.getRadius === "function"){
return "circle";
}else{
return "unknown";
}
}
