eval(stringVar+var) question

[sugarBabe]

Hej, If I have a string variable named newName and a variable name count, can I get a mc path by doing this:

frameC = eval(newName+count);

? please anser me this time I need your help aswell. Thank you for your time.

It should. If it's not working try adding in a trace to see what you are geting.

eval is deprecated. meaning it won't be around long.
but you don't need it.

frameC = "" + newName + count; // this will concatenate the two into a string

frameC = newName add count; // same


SO..... 


 MC.gotoAndPlay("" + newName + count);
 MC.gotoAndPlay(newName add count);

will both work

Actualy eval is NOT deprecated, although it doesn't work the same in F5 and FMX.

Although you don't need eval for what he is doing, what you suggest will not work.

The difference:

piece3 = "dangerous";
x = 3;
trace("piece" + x); // Output: peice3
trace(eval("piece" + x)); // Output: dangerous

And just as a point of intrest, add IS deprecated.

Maybe I didnt made myself clear. frameC is a MOvieClip INSTANCE. Are you guys sure that I dont need eval?This is the code Im using:

_root.dupli = function(frameSpace,newName) {
var i = 0;
while (i<700) {
duplicateMovieClip(_root.timeLine.frameClip1.theFr ame,newName+i, i);

var frameC = eval("/timeLine/frameClip1/"+newName+i);

frameC._x = i;
frameC.onEnterFrame=function(){
frameC.makeMeHappy(i);
}
i+=frameSpace;
}
};



By the way, dangerahead, Im not using 'add' and I dont see what 'add' has to do with 'eval' being deprecated although its not, thanks for your time and for replying anyway.

first of all, etcettera, my code works. Try it yourself.

Second of all:

_root.dupli = function(frameSpace, newName) {
	var i = 0;
	while (i < 700) {
		duplicateMovieClip(_root.timeLine.frameClip1.theFrame, newName + i, i);
		frameC = newName + i;
		_root.timeline.frameClip1[frameC]._x = i;
		_root.timeline.frameClip1[frameC].onEnterFrame = function() {
			_root.timeline.frameClip1[frameC].makeMeHappy(i);
		};
		i += frameSpace;
	}
};

you're welcome, Sugar.

First of all:

I'm not saying your code won't work, I said it wasn't what he was asking for. Your code returns a string, and although a string can be used to make a refrence to an MC, it is not in itself a refrence to one.

Second of all:

_root.dupli = function(frameSpace,newName) { 
	for (var i=0;i<700;i+=framespace) {
		duplicateMovieClip(_root.timeLine.frameClip1.theFrame,newName+i, i);
		var frameC = _root["timeLine.frameClip1."+(newName+i)]; 
		frameC._x = i; 
		frameC.onEnterFrame=function(){ 
			frameC.makeMeHappy(i); 
		}
	} 
};

or 

_root.dupli = function(frameSpace,newName) { 
	for (var i=0;i<700;i+=framespace) {
		duplicateMovieClip(_root.timeLine.frameClip1.theFrame,newName+i, i);
		var frameC = eval("timeLine.frameClip1."+(newName+i)); 
		frameC._x = i; 
		frameC.onEnterFrame=function(){ 
			frameC.makeMeHappy(i); 
		}
	} 
};

Eval or no eval, whatever floats your boat.

Hi,
Actually, there is an even easier way to do what you are trying to do, because duplicateMovieClip now returns a reference to the clip it creates. Use this:

_root.dupli = function(frameSpace,newName) { 
	for (var i=0;i<700;i+=framespace) {
		var myClip = _root.duplicateMovieClip(_root.timeLine.frameClip1.theFrame,newName+i, i);
		myClip._x = i; 
		myClip.onEnterFrame=function(){ 
			this.makeMeHappy(i); 
		}
	} 
};

This way you do not need to use eval or the [] notation. Chuckles8421
