for loop problem

[The Krook]

The following code doesn't work.
You probably already know by seeing the code what it is I'm trying to do and what I have done wrong.

for (i=1; i<=4; i++) {
	this["bt"+i].onRollOver = function() {
		this._parent["icon"+i].reverse = false;
		this._parent["icon"+i].play();
	}
}

But just to spell it out:

I have 4 buttons and 4 MC's on the same timeline. I want to have bt1 play icon1 onRollOver, bt2 to play icon2 onRollOver and so forth...

But the var i always equals 5.

I have searched and found some answers by the user silentweed but I'm apparently to dumb to understand
What do I do ?

Thank you

Couldn't figure out the problem, but here's one way to fix it -.-

for (i=1; i<=4; i++) {
	this["bt"+i].i = i;
	this["bt"+i].onRollOver = function() {
		this._parent["icon"+this.i].reverse = false;
		this._parent["icon"+this.i].play();
	}
}

As regards the variable i equalling 5. If you trace i outside of and after the execution of the loop, then i will equal 5. An event handler function executes when that event occurs. At the time of execution, it grabs the current values of the variables referenced within the function. So onRollOver, i is equal to 5 in this case.

iONx's code works works because within the loop, a new property, "i", is being defined on each of the mc's named bt1, bt2, bt3, bt4 and given the value of the i for that iteration. So bt1.i=1, bt2.i=2, bt3.i=3, bt4.i=4. Then onRollOver, the function executes referencing the current value of the i property for the mc on which it is executing. So bt3.onRollOver will play icon3 because "this" within the function refers to bt3 and bt3.i is equal to 3.

Thank you both of you.

Your code works as I want it, iONX.

BTW iONX

Can you explain why your codes work ?
I would really like to learn instead of just relying on others everytime i run into a problem.

Well, blah. My reply of last night is largely wrong. I took a second look this morning and edited the post. Sorry for misleading.
