Change Thumbnail On Click/Press

[alwaysdrifting]

Hey all,

I want to change the alpha of a thumbnail after it has been pressed, to indicate that the user has clicked it.

However, I also am changing the alpha when the user hovers over it and On Mouse Out. I've tired this:
on (press){
this._alpha -= 50;
}


What seems to happen here is that if the user clicks on it again, it can't be seen.

A problem with the below code it, On Mouse over, it fades it by 50. Then, On Click, it disappears. Then, on mouse out, it fades back to 100.

on (press){
this._alpha -= 50;
}


onClipEvent (load) {
this._alpha = 100;
}
onClipEvent (enterFrame) {
function fadeOut() {
if (this._alpha>50) {
this._alpha -= 50;
} else {
this.onEnterFrame = null;
}
}
function fadeIn() {
if (this._alpha<100) {
this._alpha += 50;
} else {
this.onEnterFrame = null;
}
}
this.onRollOver = function() {
this.onEnterFrame = fadeOut;
};
this.onRollOut = function() {
this.onEnterFrame = fadeIn;
};



}

Thanks for your help. I'd be shagged if it wasn't for this forum, you are a great help. I appreciate every reply,

Cheers,
Brian

If you press the thumbnail, it should stay at 50% alpha? Or should it return to 100% on rollout?

[alwaysdrifting]

I want it to stay at 50% alpha when pressed and always remain at 50%(A mouse over should do nothing after it's pressed) when the user is browsing that gallery. But, if they don't press it, it goes back to 100% on Mouse out.

Okay. Replace your code for this one:
//paste the code on the main timeline
MovieClip.prototype.setAlpha = function() {
this._alpha = 100;
this.fade = function(v) {
this._alpha = v;
};
this.onPress = function() {
this.fade(50);
delete this.onRollOut;
};
this.onRollOver = function() {
this.fade(50);
};
this.onRollOut = function() {
this.fade(100);
};
};
thumb1.setAlpha();//thumb1 is the instance name of your mc

Claudio: I can't seem to get this to work. I've been messing around with it but nothing. Any advise?

Cheers

claudio isnt it wiser to use hitTests instead of rollovers which behave sometimes strangely ?

[alwaysdrifting]

How would I say in an if statement, if not this.onPress?

if (this._alpha<100 && this.onPress) {
this._alpha += 50;
}

Basically, I want to say. If the alpha is less than a 100 and it isn't pressed, do....

Cheers

Hi Always,

I just tried it in a clip....you prolly didn't set your thumb to a movie clip (that is what "mc" means ) check out the fla.

cheers,

m.

Thanks a million,

My problem was that I had that code in the MC called thumb1. Cheers for helping me

@mlkdesign:
In this case i think its easier and better to use rollover and rollout events.
