Newbie question:
If I create several shape objects in a loop, like:
var i:int;
for (i = 0; i < 3; i++) {
var circle:Shape = new Shape();
circle.graphics.beginFill(color);
circle.graphics.drawCircle(100,100, radius);
circle.graphics.endFill();
addChild(circle);
}
How can I then call those different shapes separately, so I could manipulate their properties? It would seem to me they would all have the same name?
You can access them via their index (the order they have been put on the stage).
So something like:
DisplayObject(getChildAt(1)).x = 100; // Where the 1 is the index (starting at 0)
Actually, you can just have an array (or vector) of objects, so you won't depend on current displaylist.
var i:int;
var circleArray:Array = new Array();
for (i = 0; i < 3; i++) {
var circle:Shape = new Shape();
circleArrayList.push(circle);
circle.graphics.beginFill(color);
circle.graphics.drawCircle(100,100, radius);
circle.graphics.endFill();
addChild(circle);
}
//And then access them with
for(i = 0; i < circleArray.length, i++)
{
circleArrayList[i].x = 15 * i;
}
//Or
foreach(var circle:DisplayObject in circleArray)
{
circle.x = 15 * i;
}
for(int i=0;i<3;i++)
{
class x =new class(i);
x.print()
}

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);
}
i am trying to make a function where i drop some seeds into a bucket and the seeds are removed however the function will just be the seeds colliding with the bucket.
I have both of the objects as movieclips and have a basic hitTestObject conditional statement, i have no idea why the feed_mc wont be removed.
if(bucket_mc.hitTestObject(feed_mc))
{
if(stage.contains(feed_mc))
removeChild(feed_mc);
}
thank you in advance
Sorry should have edited here
my code
var Necessities:Array = new Array (Seed, shelter, water);
for(var i:int = 0; i< 10; i++)
{
var pickObjects = Necessities[int(Math.random()* Necessities.length)];
var Objects:MovieClip = new pickObjects();
addChild(Objects);
Objects.x = Math.random() + 600;
Objects.y = Math.random() * stage.stageHeight;
}
stage.addEventListener(Event.ENTER_FRAME, feedHen);
function feedHen(e:Event):void {
if(hen_mc.hitTestObject(Objects))
{
if (Objects.parent)
Objects.parent.removeChild(Objects);
}
}
Seems like
if(feed_mc.parent){
feed_mc.parent.removeChild(feed_mc);
}
should help - if you are not sure what DisplayObjectContainer is parent
edit
I think this should work
var Necessities:Array = new Array (Seed, shelter, water);
//store Objects here
var objectsVector:Vector.<MovieClip> = new Vector.<MovieClip>();
for(var i:int = 0; i< 10; i++){
var pickObjects = Necessities[int(Math.random()* Necessities.length)];
var Objects:MovieClip = new pickObjects();
addChild(Objects);
objectsVector.push(Objects);//add to Vector
Objects.x = Math.random() + 600;
Objects.y = Math.random() * stage.stageHeight;
}
stage.addEventListener(Event.ENTER_FRAME, feedHen);
function feedHen(e:Event):void {
for(var i: int = objectsVector.length - 1; i >= 0; i--){//loop through stored objects
if(hen_mc.hitTestObject(objectsVector[i])){
if (objectsVector[i].parent){
objectsVector[i].parent.removeChild(objectsVector[i]);
objectsVector.splice(i, 1);//remove from storage
}
}
}
}
However I'd suggest checking on some mouse events instead of ENTER_FRAME to reduce number of function calls
Having a bit of a problem. I'm trying to add 10 items to the stage but it is only adding 1. Any insight on what I'm doing wrong?
public var numCells:Array = [];
public function addCell():void
{
var cell:Cell = new Cell();
var i:int = 0;
cell.x = Math.floor(Math.random() * 1366);
cell.y = Math.floor(Math.random() * 768);
for(var i:int = 0; i < 10; i++)
{
numCells.push(cell);
addChild(cell);
}
return;
}
You are only ever instantiating one cell. calling addChild a second time with the same object passed in doesn't make a copy of that object, it just moves it to the top most 'layer'.
You need to instantiate a new cell inside the for loop. Something like this:
private function addCells():void {
for(var i:int = 0; i < 10; i++){
var cell:Cell = new Cell();
cell.x = Math.floor(Math.random() * 1366);
cell.y = Math.floor(Math.random() * 768);
numCells.push(cell);
addChild(cell);
}
}
Having a bit of a problem with some code I've written. Basically what it does is take 3 values that constantly change and graphs them over time in the form of a cumulative line graph. It almost works except I get this weird line drawn across the entire stage and further and I can't figure out what the issue is. The full code is below, you can run it by pasting it into flash.

y3Shape is commented out until the problem with y2Shape is fixed (having both drawn just makes the problem harder to figure out).
Any ideas what could be up?
Thanks
If you insert trace your vectors near .drawPath, you'll see something like that:
trace(y2_commands); // 1,2,2,2,2
trace(y2_coord); // 400,171,400,57,390,NaN,400,171,400,57
So, NaN (Not a Number) means, that you have error in coordinates calculating.
ps. y1[i] in first calculating of BUSY GRAPH is undefined
You seem to be using beginFill(), when you draw a path that's not looped, Flash requires your path to get looped in order to fill it with something. So, it loops it implicitly by adding a line to your starting point and filling it. In order to receive a non-overlapping path, add two points to your path that will be right below 0 point in X axis, one right under the last point on your graph, and one right under the FIRST point on the graph.
Actually, you already have them installed, but for some reason you place not 2 points, but a whole lot of em, and height position of that line is plainly wrong. Your code states:
for (i=len; i>0; i--)
{
y2_commands.push(2);
y2_coord.push(400 - i*scale, height_-(Math.round((y1[i]/max)*height_)));
}
You should have:
for (i=len; i>0; i--)
{
y2_commands.push(2);
y2_coord.push(400 - i*scale, height_);
}
Or even better:
y2_commands.push(2);
y2_commands.push(2);
y2_coord.push(400 - len*scale, height_);
y2_coord.push(400, height_);
I've just recently tried my hand at actionscript 3 and have come across a road block.
How do I go about rendering the cubes (cube1) intermittently, ie. staggered loading. I need the cubes to load a split second from each other.
Below is a snippet of what I have so far:
var rows:int = 5;
var cols:int = 3;
var spacery:int = 100;
var spacerx:int = 120;
var box_count:int = 8;
for(var i:int; i < box_count; i++) {
cube1 = new Cube(ml,100,10,80,1,1,1);
cube1.y = ((i % rows)) * (cube1.x + spacery);
cube1.x = Math.floor(i/rows) * (cube1.x +spacerx);
cube1.z = 0;
bigBox.addChild(cube1);
}
//Create an array out side the function; as a global (instance) variable:
var cubes:Array = [];
//instead of bigBox.addChild(cube1), store them in the array:
cubes.push(cube1);
//initialize a timer outside after for loop
//Fire every 100 milliseconds, box_count times
var timer:Timer = new Timer(100, box_count);
timer.addEventListener(TimerEvent.TIMER, onTick);
timer.addEventListener(TimerEvent.TIMER_COMPLETE, onTickDone);
function onTick(e:Event):void
{
bigBox.addChild(cubes[timer.currentCount]);
}
function onTickDone(e:Event):void
{
cubes = null;
timer.removeEventListener(TimerEvent.TIMER, onTick);
timer.removeEventListener(TimerEvent.TIMER_COMPLETE, onTickDone);
timer = null;
}
