I made a [color=red]for in[/color] loop and a [color=red]function[/color] to control my button mc’s like this:
```auto
for (var i in this) {
if (this*._name.substr(0, 4) == "btn_") {
setButton(this*._name);
}
}
function setButton(clip) {
var clip = eval(clip);
// The rollOver, rollOut and release stuff goes here
}
```
Now I would like to integrate the loop in the function ! I tried the following:
```auto
function setButton(clip) {
for (var i in this) {
if (this*._name.substr(0, 4) == "btn_") {
var clip = eval(this*._name);
// clip.onRollover = function(){ and the rollOut and release stuff goes here
}
}
}
}
```
but that isn’t working. Can somebody please tell me what I’m doing wrong.
Thanks in advance

I now added: [color=red]substr(4)[/color]
to the var clip part, so the complete syntax is now:
[color=red]var clip = eval(this\*.\_name.substr(4));[/color]
but still nothing. Anybody an idea what is wrong or else any sugestions where I probably can find the answer
Thanks in advance

the eval is pointless… you have a direct clip reference from your for in loop
this[i] IS the clip. Theres no point in getting the clips name from THE clip and then converting it _back_ to the clip again 😉
is the function defined in the same timeline where those buttons exist? If so (which is right) I just suggest trying some traces in there to make sure you’re actually finding your buttons in the loop i.e. trace(this\*)

It is realy strange. The trace give no result. They are on the same timeline indeed. And if I place the for in loop outsite the function they are working fine. I realy don’t understand what i’m doing wrong ?

I still haven’t figured out why the “btn\_” mc’s are not working any more after I integrated the for in loop in the function. This is how I have it now:
```auto
function setButton(clip) {
for (var i in this) {
if (this*._name.substr(0, 4) == "btn_") {
var clip = this*;
// clip.onRollover = function(){ and the rollOut and release stuff goes here
}
}
}
}
```
The function is on the main timeline but I the btn\_ mc’s I have to control are insite another MC “menuMC”
Can somebody please help me :crying:

}
}
}

welcome
Glad it worked but the other poster asked if your buttons were in the sametimeline as the code.

I know, but at that time they where. Only I changed a few things and that is why they are now integrated in that one MC. I have one more question if you don’t mind. This is my complete code:
```auto
_root.currMovie = "homede";
container.loadMovie(_root.currMovie+".swf");
function setButton() {
for (var i in menuMc) {
if (menuMc*._name.substr(0, 4) == "btn_") {
clip = menuMc*;
clip.onRollOver = function() {
new Color(clip).setRGB(0xFFFFFF);
trace(this._name);
};
clip.onRollOut = function() {
if (!this.pushed) {
new Color(clip).setRGB(0x999999);
} else {
new Color(clip).setRGB(0xFFFFFF);
}
};
clip.onRelease = function() {
resetKnop();
this.pushed = true;
new Color(clip).setRGB(0xFFFFFF);
if (_root.currMovie == undefined) {
_root.currMovie = this._name.substring(4);
this._parent.container.loadMovie(this._name.substring(4)+".swf");
} else if (_root.currMovie != this._name.substring(4)) {
if (this._parent.container._currentframe>=this._parent.container.midframe) {
_root.currMovie = this._name.substring(4);
this._parent.container.play();
}
}
};
}
}
}
function resetKnop() {
for (var i in menuMC) {
if (menuMc*._name.substr(0, 4) == "btn_") {
clip = menuMc*;
clip.pushed = false;
new Color(clip).setRGB(0x999999);
}
}
}
setButton();
```
As you can see should the buttons change color on rollOver, rollOut and release. But that isn’t working. Nomather over which button I roll only the second one change color. What should I change to make this work again?
Thanks in advance

Problem solved 🙂 I changed new Color(clip) in new Color(this)
But what should I change to make this part work again:
```auto
if (_root.currMovie == undefined) {
_root.currMovie = this._name.substring(4);
this._parent.container.loadMovie(this._name.substr ing(4)+".swf");
} else if (_root.currMovie != this._name.substring(4)) {
if (this._parent.container._currentframe>=this._parent.container.midframe) {
_root.currMovie = this._name.substring(4);
this._parent.container.play();
```

Difficult to know without seeing the file. Is container on the main timeline?If so it should be this.\_parent.\_parent.container

That was indeed the solution 🙂 Thanks 🙂
