Cache on Timeline?

[Guest]

Recently I created a function on a swf that basically hides some buttons until the audio playing on that frame is over. When this happen a function is called and the buttons became visible again.

The code is very simple. It's like this:

var my_sound:Sound = new Sound();

my_sound.loadSound("audio/som1_1.mp3",true);

my_sound.onLoad = function(sucess:Boolean){

    if( ( _root.temporizador == 1 || _root.temporizador == undefined ) && sucess ) {

        botao_avancar._alpha = 0;

        botao_avancar.enabled = false;

        my_sound.onSoundComplete = doSoundComplete;

    }

}

function doSoundComplete() {

    botao_avancar._alpha = 100;

    botao_avancar.enabled = true;

}

My problem is, whenever I change the frame, and the button is in a different place on the screen, it appears on the same position as the last frame, kind of a cache, I guess. Someone know a way to fix this? It's really weird.

I have a .fla sample of this in the link: http://ouromoderno.com.br/flashError/demo.fla
And I have an online sample, so you can see what happens: -> http://ouromoderno.com.br/flashError/

Appreciate any ideias.

(Sorry for the very bad horrible awful english )

when your button appears in a new place you have a keyframe containing the button and therefore another button instance.  making a previous button instance not visibiel won't affect the visible property of the new button instance.

to remedy, use a boolean variable to record whether your button is visible or not.  use the boolean in other frames to assign the new instances visible property:

my_sound.onLoad = function(sucess:Boolean){

    if( ( _root.temporizador == 1 || _root.temporizador == undefined ) && sucess ) {

        botao_avancar._visible=false;

botao_visible=false;

        my_sound.onSoundComplete = doSoundComplete;

    }

}

function doSoundComplete() {

    botao_avancar._visible=true;

botao_visible=true;

}

// on your other frames:

whateverbotao._visible=botao_visible;

//p.s. use the _visible property and you don't have enable/disable your button.

Thanks for the reply. I didnt know about the _visible property, thanks!
About my doubt, I am thinking on doing something like that:

I will create an array of booleans and set everything to false in the begining. Everytime I call doSoundComplete it will set that frame to true. In essence, this is what you told me to do right?

how many buttons do you need to track?

I work on a company that sells classes made in Flash. The number of frames vary, but in average it is about 50 frames. So 50 buttons per SWF 😕

it would be probably be easier to just name your buttons prudently.  for example, btn_0, btn_2, ..., btn_49;

you can then use:

// to set all visible variables true;

for(var i:Number=0;i<50;i++){

this["btn_"+i+"_visible"]=true;

}

// to set all button's _visible properites

for(var i:Number=0;i<50;i++){

this["btn_"+i]._visible=this["btn_"+i+"_visible];

}

The problem is my company has already more than 900 swf's in use. To instanciate all buttons according to this, would take a lot work. I think i will make a script that rename botao_avancar to botao_avancar+currentFrame, to avoid more problems. Thanks for the tips!
