gradual alpha fade

[rolando.lopez]

Hi,

I am trying to create a fade effect. When I click on a movie clip, I want the others to gradually fade from _alpha =100 to _alpha = 25. The way I have it now it will instantly take the clip from 100 to 25.

This is on the movie clip that I click

on(release){
this.gotoAndStop(2);
_root.disappear();
}

This is the function definition on the root:

function disappear(){
for(var i = 100; i > 25; i--){

_root["clip1"]._alpha = i;
}
}


Can you guys help me out?

Thanks

for loops do the process then show the final result. You would need to use an event handler (onEnterFrame in this case) to gradually fade your clip..

function disappear(){
//call onEnterFrame dynamic event handler
_root["clip1"].onEnterFrame = function(){
//decrement alpha by 5
this._alpha -= 5
//if the alpha is less than or equal to 25
if (this._alpha <= 25){
//set the alpha to 25
this._alpha = 25
//delete the onEnterFrame to stop decrementing the alpha
delete this.onEnterFrame
}
}

}

can you explain the significance of calling
_root["clip1"].onEnterFrame

instead of just calling
clip1.onEnterFrame
or
_root.clip1.onEnterFrame.


does it have to do with arrays?

In this case there is no difference, just personal preference.

its nothing with arrays, just that if there is a variable, and you want to target the mc with the instance name of the value of the variable, or something similar, you use _root[variable] or _root["movieclip"+i]

Lostinbeta,
thanks. That worked great!

kartik: It is something with arrays. It is called associative array referencing. All the items in a timeline are stored in an array, and you can target that timelines array to get the clip/variable you want in the method you showed.
