The drag and drop works, however, I have no idea how to create an if statement that goes to the next scene when all movieclips have been placed on the target.
I've tried placing the instance names in an if statement with the hittestobject however, no luck.
import flash.events.TouchEvent;
import flash.ui.Multitouch;
import flash.ui.MultitouchInputMode;
import flash.display.MovieClip;
/* Touch and Drag Event

*/
var objectoriginalX:Number;
var objectoriginalY:Number;
Multitouch.inputMode = MultitouchInputMode.TOUCH_POINT;
var lemons:Array = [lemon1_mc, lemon2_mc, lemon3_mc, lemon4_mc, lemon5_mc];
for each(var lemonMC:MovieClip in lemons)
{
lemonMC.buttonMode = true;
lemonMC.addEventListener(TouchEvent.TOUCH_BEGIN, pickobject);
lemonMC.addEventListener(TouchEvent.TOUCH_END, dropobject);
lemonMC.startX = lemonMC.x;
lemonMC.startY = lemonMC.y;
}
var fl_DragBounds:Rectangle = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
function pickobject(event:TouchEvent):void
{
event.target.startTouchDrag(event.touchPointID, false, fl_DragBounds);
event.target.parent.addChild(event.target);
objectoriginalX = event.target.x;
objectoriginalY = event.target.y;
}
function dropobject(event:TouchEvent):void
{
if(event.target.hitTestObject(target_mc)){
event.target.buttonMode = false;
event.target.x = target_mc.x;
event.target.y = target_mc.y;
event.target.visible = false;
} else {
event.target.x = event.target.startX;
event.target.y = event.target.startY;
event.target.buttonMode = true;
}
}
var melons:Array = [melon1_mc, melon2_mc, melon3_mc, melon4_mc, melon5_mc, melon6_mc, melon7_mc];
for each(var melonMC:MovieClip in melons)
{
melonMC.buttonMode = true;
melonMC.addEventListener(TouchEvent.TOUCH_BEGIN, pickobject2);
melonMC.addEventListener(TouchEvent.TOUCH_END, dropobject2);
melonMC.startX = melonMC.x;
melonMC.startY = melonMC.y;
}
var fl_DragBounds2:Rectangle = new Rectangle(0, 0, stage.stageWidth, stage.stageHeight);
function pickobject2(event:TouchEvent):void
{
event.target.startTouchDrag(event.touchPointID, false, fl_DragBounds2);

How about adding a counter that is equal to number of objects to drag, then every time you drop object (and detect if it was on target) you decrements the counter and at the end of the function you check if it's 0?
An easy way to do this would be to remove your lemons/melons from their arrays when they pass the hit test. Then check if each array is empty and continue to the next scene should that be the case.
You can actually reduce redundant code and use the same function (dropobject) for both lemons and melons.
function dropobject(event:TouchEvent):void {
//Figure out which array this belongs to (is it a lemon or a melon)
var array:Array; //the array the dropped item belongs to
var hitMC:MovieClip; //the hit object for the lemon or melon
if(lemons.indexOf(event.currentTarget) > -1){ //if the lemon array contains the currentTarget
array = lemons;
hitMC = target_mc;
}else{
array = melons;
hitMC = target_null;
}
if(event.currentTarget.hitTestObject(hitMC)){
event.currentTarget.buttonMode = false;
event.currentTarget.x = hitMC.x;
event.currentTarget.y = hitMC.y;
event.currentTarget.visible = false;
//remove the item from it's array
array.removeAt(array.indexOf(event.currentTarget));
//check if there are any items left
if(lemons.length < 1 && melons.length < 1){
//both arrays are empty, so move on
play(); //or however you want to move on
}
}
}
Getting more advanced, a better way to do this would be to make a base class for your lemons, melons and anything else you want to drag in the future. Then you can add the dragging functionality into that base class and add properties for the hit target and an event for when it's hit it's target. This would give you one code base that can be easily applied to any library object.
I have been struggling for a couple of days with an issue in Flash CS4. I am re-structuring an old game project into a Main class which handles the mainMenu, playGame, etc. functions. I have a ship added from the "game", which is added by Main.
The issue is "myShip" works as expected, except it's never visible. I've checked a lot of times, and both myShip and its containter (game) visible properties are always true. Alpha values are not the problem either, nor layers nor depth. Every other child I've added from "game" works just fine, but "myShip" refuses to be visible.
Any ideas as to why this could happen? I do not know how what to try next to solve the problem. Any help would be very appreciated. The code for the Main, Game and Ship class is below.
Thank you!
Code from the Main class:
public class Main extends Sprite {
public var mainMenuDisplay:MainMenuDisplay;
public var game:Game;
public var gameOverMenu:GameOverMenu;
public function Main() {
showMainMenu();
}
public function showMainMenu() {
mainMenuDisplay = new MainMenuDisplay(this);
gameOverMenu=remove_movie_clip(gameOverMenu);
addChild(mainMenuDisplay);
}
public function showGameOver() {
gameOverMenu = new GameOverMenu(this);
game=remove_movie_clip(game);
addChild(gameOverMenu);
}
public function playTheGame() {
game = new Game(this);
mainMenuDisplay = remove_movie_clip(mainMenuDisplay);
gameOverMenu=remove_movie_clip(gameOverMenu);
stage.addChild(game);
}
private function remove_movie_clip(clip:*) {

removeChild(clip);

Some basics that you have to know in order to understand what's going on.
It's a very common mistake to add things to stage.
Here's what the documentation of addChild says
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObjectContainer.html#addChild%28%29
objects should not be added to the Stage, directly, at all
I guess people add DispalyObjects to stage because they think it is
"the stage" that they see and interact with in the Flash authoring
environment. But it's not. stage.addChild() is not the same
thing as dragging a symbol from the library onto the screen. What by
default represents the main time line is the root property.
However, if you add anything to stage directly, its root property and its stage property both reference the same object,
which is regularly only referenced by stage. stage is some
container that your .swf is added to when running in the flash
player.
The documentation of addChildAt says this about the index:
http://help.adobe.com/en_US/FlashPlatform/reference/actionscript/3/flash/display/DisplayObjectContainer.html#addChildAt%28%29
The child is added at the index position specified. An index of 0 represents the back (bottom) of the display list for this
DisplayObjectContainer object.
Applying these basics, the following happens:
FlashPlayer creates the stage object, instantiates your main class
and adds that instance to stage, it is the child with the index 0.
Among other things, stage.addChildAt(mySprite, 1); is executed,
adding mySprite as a second child to stage. With index of 1 it is
rendered in front of the object that is at index 0, which happens to
be the instance of your main class AKA your .swf file. I hope that
anything being rendered "outside the .swf file" illustrates well
enough why adding things to stage is not recommended.
Later, this.addChild(myShip); happens. (Which is actually the
proper way to do it; no need to use this here:addChild(myShip);
is all you need.) and adds the ship to the display list. Assuming all
of its parents are added to the display list as well, it will be
displayed.
But you still cannot see it, because you added mySprite in front of
the instance of your main class and filled it with a content in
drawGradient() which covers up everything else.
In all honesty, the best solution would be to start over from scratch.
Working with this code will not help you in any way. Even working yourself through it and making it work somehow will not make you understand anything better (except for how not to do things). It seems like the only motivation to modify this code to use classes was for the sake of doing it. Forcing such old code into the object oriented paradigm will not work very well. The benefits of oop will not be apparent, making this experience even more frustrating.
Last but not least, do not roll your own transition code. There are many libraries that do this (including flash's own Tween class http://www.republicofcode.com/tutorials/flash/as3tweenclass/ or the popular tweenlite http://greensock.com/tweenlite)
You could try adding an ADDED_TO_STAGE event. See this excellent explanation from the master of game programming
Understanding ADDED_TO_STAGE Event
private var previousClick = null;
public static var floor1:Array = new Array();
floor1[0] = [2,1,1,1,1,1,2];
floor1[1] = [1,1,1,1,1,1,1];
floor1[2] = [1,1,1,2,1,1,1];
floor1[3] = [1,1,1,1,1,1,1];
floor1[4] = [1,1,1,2,1,1,1];
floor1[5] = [1,1,1,1,1,1,1];
floor1[6] = [2,1,1,1,1,1,2];
public function Main()
{
var tilew:int = 60;
var tileh:int = 60;
for (var i:int=0; i<floor1.length; i++)
{
for (var u:int=0; u<floor1[i].length; u++)
{
var cell:MovieClip = new Tile();
cell.gotoAndStop(floor1[i][u]);
cell.x = ((u-i)*tileh)+365;
cell.y = ((u+i)*tileh/2)+70;
addChild(cell);
cell.addEventListener(MouseEvent.CLICK, mouseclick);
}
}
function mouseclick(event:MouseEvent)
{
(event.currentTarget as Tile).outline.gotoAndStop("active");
event.currentTarget.cellSelected = true;
event.currentTarget.removeEventListener(MouseEvent.CLICK,mouseclick);
if (previousClick !== null){
(previousClick as Tile).outline.gotoAndStop(1);
event.currentTarget.cellSelected = false;
previousClick.addEventListener(MouseEvent.CLICK,mouseclick);
trace(previousClick);
}
previousClick = event.currentTarget;
previousClick.cellSelected = true;
}
So I have tiles called cells lined up to each other to make a floor. When you click a cell, the outline of that tile glows, indicating that it is currently selected. I have also created a boolean that checks if the current tile is selected. The problem is, the boolean is returning true to a tile that I clicked that isn't the currently selected one, especially the first tile I click when the game starts.
So my question is, how can I get a tile that I clicked that isnt currently selected to not equal true?
I think it caused by overlap.
you may try cell.y = ((u+i)*tileh)+70;
i have a problem with my as3 code,
i try to link a movie clip to different scene (quiz scene).
so,i have 2 quiz in total, first quiz is using external script (as)
And the second quiz have the same script like first quiz, but i placed the action script inside fla. and it had different xml.
but then this error message appeared:
TypeError: Error #2007: Parameter format must be non-null.

the first quiz played perfectly with that code,
and i have no clue why this error appeared,
i'm beginner in as3 so i'm still lack in many ways,
can anyone help me,?
i really apreciate it.. :)
Are you sure that you're parsing a non-null TextFormat instance as the second argument of createText()?
The error means that you're supplying a null value for tf:TextFormat.
Unless I am missing something, your issue is here:
messageField2 = createText("Loading Questions...",questionFormat,gameSprite,0,50,550);
&
messageField = createText("Tap Untuk Memulai",scoreFormat,gameSprite,-10,250,500);
I see questionFormat2 and scoreFormat2 are instantiated, but I never see a questionFormat or scoreFormat. Your error says that the defaultTextFormat (or TextFormat supplied using setTextFormat(), for future reference), cannot be null. Null means that the object has not been instantiated/created yet. questionFormat and scoreFormat are never instantiated. Hell, their variables do not even exist. If you were using a proper development IDE (FlashBuilder, FlashDevelop, etc), you'd never be able to compile this code.
Switch those two lines to use the correct formats and you should be fine.
