a range for a random animation AS3

Hi there,

I don't have time to test it - but the solution should be something like:

<code snippet>

Try it out :)

Kindly,
Samuel

holder_mc.x -= x+ Math.random()* 380;
holder_mc.y -= y+ Math.random()* 250;
 
// New code, tests position
if (holder_mc.x < 0) holder_mc.x = 0;
if (holder_mc.y < 0) holder_mc.y = 0;
if ((holder_mc.x + holder_mc.width) < stage.stageWidth) holder_mc.x = stage.stageWidth- holder_mc.width;
if ((holder_mc.y + holder_mc.height) < stage.stageHeight) holder_mc.y = stage.stageHeight - holder_mc.height;

hi
thanks for the answer, but it does not work. i tried to play with the code you gave (which specify more the boundaries than my code) but i cannot make it work.

any suggestion?

Could you upload the swf so that we can see the effect without my code? :)

Are you sure that this line is OK?

holder_mc.graphics.drawRect(0,0, stage.stageWidth + 200,stage.stageHeight + 200);

This means every Sprite you create will be 200 pixels bigger than your movie entire width and height, thus always being outside. (Aside from the random x and y positions)

Ah, nevermind, I suppose that the custom Tweener class makes an effect so they're 200x200.

Knowing that, I think you'll need a onMotionFinished handler and then check the x and y positions with the code SamuelRostol provided.

hi
first of all,you are right about the tween. i have entered that code on the onComplete but it still does not limit itself to the stage size. i played with the code again and again, it all looks so reasonable but it will not work.

i uploaded the files (fla and swf) here:

thanks for the help

Maybe something like the following will do the trick:

(I used the normal Tween class you can safely replace those two Tweens for your custom Tweener class)

<code>

//import caurina.transitions.*;
import fl.transitions.Tween;
import fl.transitions.TweenEvent;
import fl.transitions.easing.*;
 
var holder_mc:Sprite = new Sprite();
holder_mc.alpha =0; 
 
var widthRange:Number = 200;
var heightRange:Number = 200;
 
function dropPics ():void {
	for(var i:int =0 ; i < 8; i++){
	holder_mc = new Sprite();
	holder_mc.graphics.beginFill(0x000000);
	holder_mc.graphics.drawRect(0,0, stage.stageWidth + 200,stage.stageHeight + 200);
	holder_mc.graphics.endFill();
	//trace(i);
	holder_mc.name = "holder" + i;
	y = Math.random()*200;
	x = Math.random()*200;
	holder_mc.x = x;//+ Math.random()* 500;
	holder_mc.y = y;//+ Math.random()* 500;
	holder_mc.x > 240 ? holder_mc.x -= widthRange : false;
	holder_mc.y > 120 ? holder_mc.y -= heightRange : false;
	holder_mc.x < 0 ? holder_mc.x = 0 : false;
	holder_mc.y < 0 ? holder_mc.y = 0 : false;
	var heightTween:Tween = new Tween(holder_mc, "height", Strong.easeOut, holder_mc.height, 100, 1, true);
	var widthTween:Tween = new Tween(holder_mc, "width", Strong.easeOut, holder_mc.width, 100, 1, true);
	//Tweener.addTween(holder_mc,{height: 100,width:100 ,alpha: 1,time: 1,transition: "easeOut",onComplete:rangeit()});
	var ds:DropShadowFilter = new DropShadowFilter(5,45,0x999999,0.5,4,4,1,5);
	holder_mc.filters = [ds];
	addChild(holder_mc);
	holder_mc.buttonMode = true;
 
	holder_mc.addEventListener(MouseEvent.CLICK ,tellname);
	}
}
 
dropPics();
 
function tellname (e:MouseEvent):void {
	trace(e.target.name);
}

Hi
thanks for the help. it does scatter and does not cross the stage, but i want a bigger scattering and when i add to the:
y = Math.random()*450;
x = Math.random()*300;
it allow for a bigger scattering but then again, goes beyond the boundaries of the stage.
so how can i widen the scattering without losing the stage?

i guess we are right before solving it, i hope:)

thanks for your help

best regards

ron

thanks :)

You're welcome, glad it worked for you ;)
