AS3: Car movement speed - actionscript-3

I'm beginer in AS3. I'm working follow a tutorial frogger game, you can view full code at here http://www.makeflashgames.com/tutorialsplus/tutorial-frogger.php. At Function startGame(), I know "speedX" is moving speed of the car in the direction of X. I try to change speedX to speedY, but nothing happen, the car just dose not move. Please help me write a function to moving the car follow X and Y. Or please help me make it clear...Thanks :)
public function startGame()
{
timeElapsed = 0;
totalTimer = 99;
life = 3;
p1speedX = 0;
p1speedY = 0;
gotoWin = false;
gotoLose = false;
standingOnLog = false;
cars = new Array();
logs = new Array();
homes = new Array();
logsYPos = new Array(115,165,215,265);
carsYPos = new Array(365,415,465,515);
setupGame();
//Spawn Cars
//Row 1
for (var i=1; i<=2; i++)
{
var newCar = new Car();
newCar.x = -300 * i;
newCar.y = carsYPos[0];
newCar.speedX = 150;
cars.push(newCar);
addChild(newCar);
}
//Row 2
for (var i=1; i<=3; i++)
{
var newCar = new Car();
newCar.x = (170 * i) + 500;
newCar.y = carsYPos[1];
newCar.speedX = -5;
cars.push(newCar);
addChild(newCar);
}
//Row 3
for (var i=1; i<=3; i++)
{
var newCar = new Car();
newCar.x = (-220 * i) + 100;
newCar.y = carsYPos[2];
newCar.speedX = 8;
cars.push(newCar);
addChild(newCar);
}
//Row 4
for (var i=1; i<=3; i++)
{
var newCar = new Car();
newCar.x = (200 * i) + 350;
newCar.y = carsYPos[3];
newCar.speedX = -5;
cars.push(newCar);
addChild(newCar);
}

This function doesn't move the cars, it just sets their speed.
Look at Part 9, handleGameLogic(), for movement.

Use a child in as3 adobe animate

I making a card game and i call some cards from the library randomly.
But i cant use this cards.
Is there any way to make this childs clickable?
And another question please.
If there any chance to use one print array for all the 22 cards i need to show on stage?Or i must to create a new printarray and a new random number for each card?
Note:each card has different points.
var cards:Array = [k1, p1, s1, r1, r3,k4,p4,s4,r4,k5,p5,s5,r5
,k6,p6,s6,r6,k7,p7,s7,r7,k8,p8,s8,r8,k9,p9,s9,r9,k10,p10,s10,r10,
kj,pj,sj,rj,kq,pq,sq,rq,kk,pk,sk,rk];
var printArray:Array = [];
for (var n:int = 1; n <= 1; n++)
{
var randNo:int = int(Math.random() * 51);
printArray.push(randNo);
}
for (var c:int = 0; c < printArray.length; c++)
{
trace(printArray[c]);
var mc:MovieClip = new cards[printArray[c] ];
addChild(mc);
mc.width = 60;
mc.height = 80;
mc.x = 100;
mc.y = 50;
}
var print1Array:Array = [];
for (var n1:int = 1; n1 <= 1; n1++)
{
var rand1No:int = int(Math.random() * 51);
print1Array.push(rand1No);
}
for (var c1:int = 0; c1 < print1Array.length; c1++)
{
trace(print1Array[c1]);
var mc1:MovieClip = new cards[print1Array[c1] ];
addChild(mc1);
mc1.width = 60;
mc1.height = 80;
mc1.x = 70;
mc1.y = 80;
}
stage.addEventListener(Event.ENTER_FRAME,looping);
function looping(event:Event):void
{
//here ia want use the cards.Let say i want to if(mc1 is clicked)
}
mc1.addEventListener(MouseEvent.CLICK, clickCard);
Put that where you have your other mc1's. Then elsewhere, outside any other functions put this:
private function clickCard(e:MouseEvent):void{
//trace(e.target);
}

How to Save positions for 3 objects in Array to make random position between each other by AS3?

How to Save positions for 3 objects in Array to make random position between each other by AS3?
import flash.geom.Point;
var arry:Point = new Point();
arry[0] = arry[78,200];
arry[1] = arry[217,200];
arry[2] = arry[356,200];
//object called b1
b1.x = arry[0][0];
b1.y = arry[0][1];
//object called b2
b2.x = arry[1][0];
b2.y = arry[1][1];
//object called b3
b3.x = arry[2][0];
b3.y = arry[2][1];
//make objects swap positions between each other
var rand:Number = (Math.random()*arry.length);
//output to see random position [[78,200],[217,200],[356,200]]
trace(arry);
to get random with tween like this... https://www.youtube.com/watch?v=8m_m64plQ6E
At compile time you should get this Error I suppose : "ReferenceError: Error #1069"
Here is a way to store the positions (like in the link you provided from youtube) :
import flash.geom.Point;
var squareWidth:uint = 40;
var squareHeight:uint = 40;
var marginX:uint = 100;
var marginY:uint = 75;
var spacer:uint = 10;
var positions:Vector.<Point > = new Vector.<Point > (9);
function setPositions(v:Vector.<Point>):void {
var count:uint = 0;
var posx:uint;
var posy:uint;
for (var i = 0; i < 3; i ++)
{
for (var j = 0; j < 3; j ++)
{
posx = (j * squareWidth) + (spacer * j) + marginX;
posy = (i * squareHeight) + (spacer * i) + marginY;
v[count] = new Point(posx,posy);
count++;
}
}
}
setPositions(positions);
trace(positions);
// output :
// (x=100, y=75),(x=150, y=75),(x=200, y=75),(x=100, y=125),(x=150, y=125),(x=200, y=125),(x=100, y=175),(x=150, y=175),(x=200, y=175)
So here you have nine Points to place the clips like in the video.
You just have to add a function to swap the nine boxes stored in another Vector.
In your case.
For 3 positions do the following if I understand your question.
import flash.geom.Point;
var positions:Vector.<Point> = new Vector.<Point>(3);
var p1:Point = new Point(78,200);
var p2:Point = new Point(217,200);
var p3:Point = new Point(356,200);
positions[0] = p1;
positions[1] = p2;
positions[2] = p3;
trace(positions);
// output : (x=78, y=200),(x=217, y=200),(x=356, y=200)
So, you're still unclear!
Your issue is to find a random position?
This may help you if this is the problem you're facing :
import flash.geom.Point;
var positions:Vector.<Point > = new Vector.<Point > (3);
var numbers:Vector.<uint> = new Vector.<uint>();
var numbersAllowed:uint = 3;
var rndNmbrs:Vector.<uint> = new Vector.<uint>(3);;
var p1:Point = new Point(78,200);
var p2:Point = new Point(217,200);
var p3:Point = new Point(356,200);
positions[0] = p1;
positions[1] = p2;
positions[2] = p3;
trace(positions);
function populateRndNmbrs(n:uint):void {
for (var i:uint = 0; i < n; i++)
{
numbers[i] = i;
}
}
populateRndNmbrs(numbersAllowed);
function populateRandomNumbers(n:uint):void
{
var rnd:uint;
for (var i:uint = 0; i < n; i++)
{
rnd = numbers[Math.floor(Math.random() * numbers.length)];
for (var j:uint = 0; j < numbers.length; j++)
{
if (rnd == numbers[j])
{
numbers.splice(j,1);
}
}
rndNmbrs[i] = rnd;
}
}
populateRandomNumbers(numbersAllowed);
trace("rndNmbrs = " + rndNmbrs);
for (var i:uint = 0; i < numbersAllowed; i++)
{
trace("b"+ (i+1) + ".x = " + positions[rndNmbrs[i]].x);
trace("b"+ (i+1) + ".y = " + positions[rndNmbrs[i]].y);
// In place of trace, you should place the boxes at those random positions.;
}
//output:
//(x=78, y=200),(x=217, y=200),(x=356, y=200)
//rndNmbrs = 2,0,1
//b1.x = 356
//b1.y = 200
//b2.x = 78
//b2.y = 200
//b3.x = 217
//b3.y = 200
Is that what you want? Or do you want to know how to create a motion effect?
I'm not sure about what you really need...
This will help you to place all the boxes in a random position.
You may do this like here bellow, and add a function to check if the random positions are not the same.
With only 3 MovieClips, you will often have the same random positions as long they're stored in the "positions Vector"
var squares:Vector.<MovieClip> = new Vector.<MovieClip>(3);
function populateMCs(target:DisplayObjectContainer,n:uint):void{
for (var i:uint = 0; i < n; i++){
squares[i] = target["b"+(i+1)];
}
}
function swapMCs():void{
for (var i:uint=0; i<squares.length; i++){
squares[i].x = positions[rndNmbrs[i]].x;
squares[i].y = positions[rndNmbrs[i]].y;
}
}
populateMCs(this,numbersAllowed);
swapMCs();
I give you a last example to get a motion effect in AS3.
I'm not a translator AS2 -> AS3 and a video is not the best way to show your code :(
This will make your boxes move smoothly, but not the way you want.
Now, you have to learn AS3 and try to make the job by yourself.
Then, if you have another issue, just ask clearly what you want.
var friction:Number = 0.15;
setDestination(squares[0],squares[0].x,350,friction);
setDestination(squares[1],squares[1].x,350,friction);
setDestination(squares[2],squares[2].x,350,friction);
squares[0].addEventListener(Event.ENTER_FRAME,moveClip);
squares[1].addEventListener(Event.ENTER_FRAME,moveClip);
squares[2].addEventListener(Event.ENTER_FRAME,moveClip);
function setDestination(mc:MovieClip,x:uint,y:uint,friction:Number):void{
mc.destinx = x;
mc.destiny = y;
mc.f = friction;
}
function moveClip(e:Event):void{
var mc:MovieClip = e.target as MovieClip;
trace(mc.name)
mc.speedx = (mc.destinx - mc.x);
mc.speedy = (mc.destiny - mc.y);
mc.x += mc.speedx*mc.f;
mc.y += mc.speedy*mc.f;
if((Math.floor(mc.speedx)<1) && (Math.floor(mc.speedy)<1)){
mc.removeEventListener(Event.ENTER_FRAME,moveClip);
trace("STOP MOVE FOR " + mc.name);
}
}

Position of buttons as3

I need some help with Positions of buttons in AS3. Same as before Topic, i made a IRC client with AS3, but when a user join a channel, there will be a button added, but if there is already a button and the user join new channel on IRC, there will be added new button also, this for every channel that a user does join, but It should to be positioned after the last button (side by side). Same for if a user join more channels. How can i do this on best way with x and y positions?
This is my code for now:
function onChannelButton(channel)
{
var test:MovieClip = new MovieClip();
var btn:Button;
for(var j:int = 0; j < btn.length; j++) {
btn = new Button();
btn.name = "btn";
btn.label = channel;
btn.width = 90;
btn.x = 120;
btn.y = 487.25;
test.addChild(btn);
}
addChild(test);
}
Hopefully, u can help me! Thanks!
Try this:
const PADDING:uint = 10;
const NUM_BUTTONS:uint = 10;
onChannelButton();
function onChannelButton():void {
var test:Sprite = new Sprite();
var btn:Button;
//NUM_BUTTONS or btn.length ? (Don't know about your Button class
for (var i:int = 0; i < NUM_BUTTONS; i++)
{
btn = new Button();
btn.name = "btn";
btn.width = 90;
btn.x = (btn.width + PADDING) * i;
test.addChild(btn);
}
addChild(test);
}
I typically do something like the following, using your iterator j to determine the x and y position.
I've created four variables to hopefully make the code pretty self explanatory. In this case, the y position does not change per btn, which is why the btnSpacingY is set to 0.
var btnStartX:Number = 120;
var btnStartY:Number = 487.25;
var btnSpacingX:Number = 120;
var btnSpacingY:Number = 0;
function onChannelButton(channel) {
var test:MovieClip = new MovieClip();
var btn:Button;
for (var j:int = 0; j < 10; j++) {
btn = new Button();
btn.name = "btn";
btn.label = channel;
btn.width = 90;
btn.x = btnStartX + (j * btnSpacingX);
btn.y = btnStartY + (j * btnSpacingY);
test.addChild(btn);
}
addChild(test);
}

Create multiple shapes dynamically in ActionScript 3

This is code that I use. I am trying to dynamically create multiple shapes and create animation (function drawLine) with them. I have result shows me only one animation(first one) and then nothing. It should be 6 animation. I think that addChild() function is not creating multiple shapes as I wanted.
import flash.display.Shape;
var startPoint:Point = new Point();
var endPoint:Point = new Point();
var prog:Number = 0;
var bonus:Number = 1;
var frames:int = 150;
var numbers:Array = new Array();
numbers[0] = new Array();
numbers[0][0] = 460;
numbers[0][1] = 100;
numbers[1] = new Array();
numbers[1][0] = 10;
numbers[1][1] = 20;
numbers[2] = new Array();
numbers[2][0] = 10;
numbers[2][1] = 100;
numbers[3] = new Array();
numbers[3][0] = 10;
numbers[3][1] = 180;
numbers[4] = new Array();
numbers[4][0] = 160;
numbers[4][1] = 20;
numbers[5] = new Array();
numbers[5][0] = 160;
numbers[5][1] = 100;
numbers[6] = new Array();
numbers[6][0] = 160;
numbers[6][1] = 180;
numbers[7] = new Array();
numbers[7][0] = 310;
numbers[7][1] = 20;
numbers[8] = new Array();
numbers[8][0] = 310;
numbers[8][1] = 100;
numbers[9] = new Array();
numbers[9][0] = 310;
numbers[9][1] = 180;
var fullDate:String = "271524";
var i:Number;
var pom:Number;
var shapes:Vector.<Shape> = new Vector.<Shape>();
for (i=0; i < fullDate.length; i++){
pom = int(fullDate.charAt(i));
shapes[i] = new Shape();
addChild(shapes[i]);
trace(numbers[pom+1][0]);
drawLine(numbers[pom][0], numbers[pom][1], numbers[pom+1][0], numbers[pom+1][1], 120);
}
function drawLine(startX:Number, startY:Number, endX:Number, endY:Number, time:Number = 120):void {
startPoint.x = startX;
startPoint.y = startY;
endPoint.x = endX;
endPoint.y = endY;
frames = time;
prog = 0;
this.addEventListener(Event.ENTER_FRAME, tick);
}
function drawLineTick(progress:Number):void{
for each(var shape:Shape in shapes)
{
shape.graphics.clear();
shape.graphics.lineStyle(14,0x2dfdfd);
shape.graphics.moveTo(startPoint.x,startPoint.y);
shape.graphics.lineTo(startPoint.x + ((endPoint.x - startPoint.x) * progress), startPoint.y + ((endPoint.y - startPoint.y) * progress));
}
}
function tick(e:Event):void {
if(prog >= frames){
this.removeEventListener(Event.ENTER_FRAME, tick);
}
drawLineTick(prog / frames);
prog += bonus;
}
The problem is, s only refers to the last Shape you created. Try something like this: (at the moment, all the shapes are on top of each, so you won't see multiple animations, but you can adjust that)
fullDate = "174689";
var shapes:Vector.<Shape> = new Vector.<Shape>();
for (i=0; i < fullDate.length; i++){
pom = int(fullDate.charAt(i));
shapes[i] = new Shape();
addChild(shapes[i]);
drawLine(numbers[pom][0], numbers[pom][1], numbers[pom+1][0], numbers[pom+1][1], 50);
}
function drawLine(startX:Number, startY:Number, endX:Number, endY:Number, time:Number = 120):void {
startPoint.x = startX;
startPoint.y = startY;
endPoint.x = endX;
endPoint.y = endY;
frames = time;
prog = 0;
this.addEventListener(Event.ENTER_FRAME, tick);
}
function drawLineTick(progress:Number):void{
for each(var shape:Shape in shapes)
{
shape.graphics.clear();
shape.graphics.lineStyle(14,0x2dfdfd);
shape.graphics.moveTo(startPoint.x,startPoint.y);
shape.graphics.lineTo(startPoint.x + ((endPoint.x - startPoint.x) * progress), startPoint.y + ((endPoint.y - startPoint.y) * progress));
}
}
function tick(e:Event):void {
if(prog >= frames){
this.removeEventListener(Event.ENTER_FRAME, tick);
}
drawLineTick(prog / frames);
prog += bonus;
}

getting array coordinates (8 queens problem)

I am trying to make a graphic program that solves the 8 queens problem and so far what i have is the chess board
var chessBoard:Array = new Array();
for(var i:int = 0; i < 4; i++)
{
chessBoard.push(new Array(1,0,1,0,1,0,1,0));
chessBoard.push(new Array(0,1,0,1,0,1,0,1));
}
var tileSize:int = 20;
function createChessBoard():void
{
for(var i:int = 0; i < chessBoard.length; i++)
{
for(var j:int = 0; j < chessBoard[i].length; j++)
{
var tile:Sprite = new Sprite();
var tileColor:int = chessBoard[i][j] * 0xffffff;
tile.graphics.beginFill(tileColor);
tile.graphics.drawRect(0, 0, tileSize, tileSize);
tile.graphics.endFill();
tile.x = j * tileSize;
tile.y = i * tileSize;
addChild(tile);
}
}
}
createChessBoard();
(thanks André for this code)
this creates a black and white checkered board for the problem but now i need to be able to place the queens. How am i able to see where the user clicks in order to put the queen in the box that is clicked on?
(sorry if my question isn't fully clear)
I added a very simple example to your question. See below:
var chessBoard:Array = new Array();
for(var i:int = 0; i < 4; i++)
{
chessBoard.push(new Array(1,0,1,0,1,0,1,0));
chessBoard.push(new Array(0,1,0,1,0,1,0,1));
}
var tileSize:int = 20;
function createChessBoard():void
{
for(var i:int = 0; i < chessBoard.length; i++)
{
for(var j:int = 0; j < chessBoard[i].length; j++)
{
var tile:Sprite = new Sprite();
var tileColor:int = chessBoard[i][j] * 0xffffff;
tile.graphics.beginFill(tileColor);
tile.graphics.drawRect(0, 0, tileSize, tileSize);
tile.graphics.endFill();
//I added the name property and a MouseEvent.CLICK event listener
tile.name = "tile__" + i + "_" j + "_sp";
tile.addEventListener(MouseEvent.CLICK, onTileClick);
tile.x = j * tileSize;
tile.y = i * tileSize;
addChild(tile);
}
}
}
function onTileClick(event:MouseEvent):void
{
//This tells you which tile the user clicked on
trace(event.target.name);
};
createChessBoard();
Good luck,
Rob
