</div>

[AS]MovieClip.prototype.moveIf = function(move){  
this.onEnterFrame = function(){  
if(move == true){  
move();  
}  
}  
}  
//example usage

theClip.moveIf(1 == 1);

//in this example theClip will always move. you can use any conditional statement though.  
[/AS]

or with a button:  
[AS]  
//enter the prototype above.

//code on main timeline:

toggle\_btn.onRelease = function(){  
if(move == undefined){  
var move = true;  
}  
move = !move  
}

randomMove.moveIf(move);  
[/AS]

hello njs!

tnx 4 that!

would that button work if the move-function werent in the mc’s but in the main-timeline aswell?

i attached a fla so you can see what i mean.

and another problem i guess is that i create the mc’s by a for-loop…and i want to stop em moving and stay put when i click on them…so i think i need to put the “stop-order” somewhere in the mcs themselves.

i hope you understand what i mean…👽
