Hi, i have an issue (1 of many) 😛

I duplicate a MC from my Library and arrange on stage, using:

for (var x=0; x\<4; x++){  
for (var y=0; y\<4; y++){  
this.attachMovie(“dot”,“dot”+ ++depth, depth)  
this[“dot”+depth].\_x =515.9 + x \* 17.2  
this[“dot”+depth].\_y =199.2 + y \* 17.2  
}  
}

however, i also have a script which i wish to attatch, so the MC becomers draggable.  
I normally use this: (The Mc contains a button)

on(press){  
this.startDrag();  
}

on(release){  
this.stopDrag();  
if(this,hitTest(\_root.trash)){  
\_root.trash.gotoAndPlay(2);  
unloadMovie(this);  
}  
}

Anyone know how to do this?..

Thanks! :chinaman:

HI. What is the above code for? I am trying to do something where I have a bunch of polka dots on the screen and the user can drag them around to form designs. However, I am not sure if I should use duplicate movie clip, plus I am having probs individually dragging them. I tried putting each dot on individual layers but that doesn’t seem to work. Any sggestions on how to create many individual instances of one movie clip that are individually draggable?  
I also have them color coded, for instance on the left side I have color samples so you canc hange the color of the dots. That is why the dots are instances and not separate, so I don’t have to Set RGB for every single one of them.  
I would appreciate a response, if you ever look at this post.

to affect each dot, you should make a prototype and assign it to each dot that you duplicate… like this:  
[AS]numDots = 10;  
scrnW = 300;  
scrnH = 200;  
MovieClip.prototype.drag = function() {  
this.onMouseDown = function() {  
if (this.hitTest(\_xmouse, \_ymouse, true)) {  
this.startDrag();  
}  
this.onMouseUp = function() {  
this.stopDrag();  
};  
};  
};  
for (i=1; i\<=numDots; i++) {  
dot = “dot”+i;  
\_root.attachMovie(“dotID”, dot, i);  
\_root[dot].\_x = Math.random()\*scrnW;  
\_root[dot].\_y = Math.random()\*scrnH;  
\_root[dot].drag();  
}[/AS]

Can I do the prototype function in Flash 5? I tried it and it shows no error but it doesn’t work either. Hm. So I’m making a dot, and duplicating it with control-D and then putting the script on each dot? Is the “numDot” supposed to physically exist or is it just for the “for” statement? WHy is it that I have to have the “numDot” rather than just using “dot?”

Thank you so much for helping.
