[AS2] Edit variable through a function?

[Skribble_Style]

Solution is in ImprisonedPride's post - Thanks again!

Hey guys. I've hit a little snag with my project and Im not sure how to proceed.

I have a function that is used to customize the users controls, and I pass a variable to it for updating the screen with which keys are assigned to what controls.

For examples sake, this is the code:

code:

---

upKey = 87;



upKeyBTN.onRelease = function(){

     setCustomKeys(upKey);

}



function setCustomKeys(keyToSet){

     newKey = *key pressed by user*;

     keyToSet = newKey;

}

---

What I can't seem to do is get upKey updated with the new key from inside the function. As my example shows, I tried using keyToSet = newKey, but that doesn't seem to work. I need to use upKey in a few other places in the function too, so how can I make a direct reference to it from inside the function?

The whole point of doing it this way is so that I can customize each key with just one function.

Any ideas on how I can achieve this? Thanks!=)

I have a few theories, but I can't test it now as I am in a bit of hurry, but I would suggest you to use setter methods (as in getter/setter) to update variables.

_global.upkey = 87;

function set upkey(val)
{
  //whatever code
}

or you can use "switch case" inside the function

Hmmm.

If I have to use the set method the way you have it above for every key, then that would require each key getting it's own function, which I could have done already. The whole point of doing things the way I have it in my original post is so that I can use 1 function for all keys.

Thanks for the reply though!

I think I see what you're getting at here. You can target a variable on the root timeline with the following code because what you have is an issue with scope.

upKey = 87;



upKeyBTN.onRelease = function(){

     setCustomKeys("upKey");

}



function setCustomKeys(keyToSet){

     newKey = *key pressed by user*;

     _root[keyToSet] = newKey;

}

Ahhh! That worked a treat. Thanks a lot!!
