invisible buttons controlled by nested movieclip

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!

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;

}

}

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.

    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!!!
