invisible buttons controlled by nested movieclip

[LeticiaMR]

Hi,

I have buttons btn_next and btn_previous in my timeline for controlling a movieclip mc_animals. However, I wanna btn_previous.visible = false when mc_animals is in the first frame, and btn_next.visible = false when mc_animals is in the last frame (frame 15 in this case).

Have been trying to create a function but didn't succeed... and I am also in doubt if the function should be placed in any frame in my timeline, or inside the timeline of the mc_animals.

Any guidance?

Thanks!

Hi.

AS3 or JavaScript?

And what is your code and where is it placed now?

Hi João!

I forgot to mention it ... sorry. It's HTML5 doc, so I guess it is JavaScript, right?

I tried creating the below function at first frame of my timeline...

this.prevBtnVisibility = function() {

var frameNumber = this.mc_animals.currentFrame;

if (frameNumber == 0){

this.btn_previous.visible = false;}

else {

this.btn_previous.visible = true; }

then calling the function from within the nested movieclip:

parent.prevBtnVisibility();

Hey guys!

I've realized my mistake!!

When calling the function within the nested movieclip, I have to use:

this.parent.prevBtnVisibility();

I was forgetting the this.

Thanks!!!

are mc_animals and both buttons on the same timeline?

when are the buttons visible?

[LeticiaMR]

Yes, all 3 are actually in the same frame at the timeline... and actually no matter where I place the function and/or call it, the previous button is still showing.

The closest response I got was that the whole frame disappeared (like skipped the frame) where the previous buttons should been invisible.

on that timeline that contains all 3 objects:

var animalsI;

clearInterval(animalsI);

animalsI=setInterval(animalsF.bind(this),1000/createjs.Ticker.framerate);

function animalsF(){

if(this.mc_animals.currentFrame==0){

this.btn_previous.visible=false;

} else {

this.btn_previous.visible=true;

}

if(this.mc_animals.currentFrame==this.mc_animals.totalFrames-1){

this.btn_next.visible=false;

} else {

this.btn_next.visible=true;

}

}
