applying a function to multiple movieclips?

[DGTLguy]

i have a sprite that grows as the mouse nears it, and shrinks as it pulls away using the distance formula (provided by the great wangbar)..

how can i apply this to multiple instances on the stage??

ActionScript.......//


function scanClip () {
// distance formula
diffX = _xmouse-clip._x;
diffY = _ymouse-clip._y;
// scaling
scale = 300-Math.sqrt(diffX*diffX+diffY*diffY);
scale = (scale<100) ? 100 : scale;
clip._xscale = clip._yscale=scale;
};
Clip.onEnterFrame = scanClip;
;
//

stop();
//

btw ... i have the actionscript sitting on the first frame of the movie

Hi TGTLguy,

what I'd propose is that you name all your clips that should be controled by this function as follows: clip1, clip2, clip3,...

Then insert this code on your first keyframe:

scanClip = function () {
	// distance formula
	var diffX = _xmouse-this._x;
	var diffY = _ymouse-this._y;
	// scaling
	var scale = 300-Math.sqrt(diffX*diffX+diffY*diffY);
	var scale = (scale<100) ? 100 : scale;
	this._xscale = this._yscale=scale;
	this.onEnterFrame = scanClip;
};
// 
for (i=1; i<4; i++) {
	clip = eval('clip'+i);
	clip.onEnterFrame = scanClip;
}
stop();

The 'for-statement' at the end attaches the function to all clips. This example works for 3 clips. If you had 7 for example you'd have to replace the '4' in the for-statement by a 8.


Hope that helps!

regards

thank you firegambler... it worked easy as pie...

its always the simple stuff...

 

[DGTLguy]

ok... i have four sprites on the stage with the scanClip function (look above) attached to each...

each are scaling as you move your mouse across the screen.

now, is it possible to use an onPress event to stop each MC at their current positions...

Try this...

...
for (i=1; i<4; i++) {
    clip = eval('clip'+i);
    clip.onPress = function(){
        clip.stop();
    };
    clip.onEnterFrame = scanClip;
}
stop();

Mind you I'm not too found of your use of &quot;eval&quot;, associative array syntax may be better.

Oh! Might be a better idea to use &quot;my_clip&quot; rather than &quot;clip&quot; alone.

for some reason that did not work oldnewbie...

Can you post a link to your .fla or a mockup?
