Enable/disable button at certain point in timeline

[darrenl38734845]

I've reviewed similar questions but still cannot resolve my specific issue. I have a button that on click goes to a certain point in the timeline and plays. The issue is that while the timeline is playing, this button is still enabled- and if you click it it takes the user back to the first frame. I want to just disable this while it plays, and then reenable once completed.

this.button_4.addEventListener("click", fl_ClickToGoToAndPlayFromFrame_6.bind(this));
function fl_ClickToGoToAndPlayFromFrame_6()
{
this.gotoAndPlay(2);
}

and then on the first frame of the animation, I have created a keyframe and added

button_4.enabled=false;

But this does not work.

Please advise?

Did you forget to add "this." before "button_4.enabled=false;" ?

I tried that. still no dice.

It should actually be: this.button_4.mouseEnabled = false;

Well this is fun... in CreateJS, buttons are created by attaching the ButtonHelper class to a movieclip instance. But in the Animate generated code the class is attached anonymously, like this:

new cjs.ButtonHelper(this.btn, 0, 1, 1);

So all the properties of ButtonHelper (like enabled) are completely inaccessible. Good job guys.

Anyway, the simplest way to disable the button would be to just hide it... this.button_4.visible = false;  ... Can't click something that's not there.

A more elegant solution would be to fade the button out, indicating it's temporarily not available. For this you could do something like this.button_4.alpha = 0.5; then modify your event code like so...

function fl_ClickToGoToAndPlayFromFrame_6(evt) {

     if (evt.currentTarget.alpha === 1) {

          this.gotoAndPlay(2);

     }

}

Alternatively, you could leave the event code alone and disable with this:

this.button_4.alpha = 0.5;

this.button_4.mouseEnabled = false;

Then enable with this:

this.button_4.alpha = 1;

this.button_4.mouseEnabled = true;

There's lots of ways to do this sort of thing.
