Setting dynamic variables

[Rancor]

I have set up a "for" loop that I would like to have set the alpha for a number of variables. I know I can set a variable this way:

_root.treeListenerFront.treeListener1._alpha=0;

And I know I can set a dynamic variable using an array:

for(i=1; i<=32; i++){
     _root["treeListenerFront.treeListener"+i]=0;
}

But I can't seem to use the second method to set the alpha value. For instance, the following isn't working for me:

_root["treeListenerFront.treeListener"+i+"._alpha"]=0;

What is the best way to go about doing this?

Thanks, in advance.

_root["treeListenerFront.treeListener"+i] gives you an object (associative array access). Square brackets are used for object's name evaluation. I hope this is clean.

Then, to solve your problem you should correct your code this way:

this["myObjNumber" + i]._alpha = someAlpha;

I'm not the most expert programmer, so I'm not sure I understand everything you've told me, but I tried using your example and it still isn't working.

I have:

//_root.treeListenerFront.treeListener1._alpha=0;
_root["treeListenerFront.treeListener"+i]._alpha=0;

The commented code will deliver exactly what I want, but it's not dynamic. It seem sthat the un-commented code should work, but it doesn't do anything.

I've narrowed the problem a little bit, I think.

_root["treeListenerFront"]._alpha=0;

will work, but it's when I add the additional ".treeListener" + i] that things stop working.

So it must be something with this part of the code. Is the engine trying to add the number to the string, instead of attaching it?

(I've set up another working example in another file that does what I want it to (minus the ._alpha)

It is set up like this:
_root["leafMG.leafGenerator.leafPlayed"+leafCount]=false;
which is pretty similar, and this one works.)

So anybody else have any thoughts?

_root.treeListenerFront["treeListener"+i]._alpha=0;

Foolish!

Thanks, man. It works now.
