Deleting texture from memory

[bubamara]

Hi,

 

to prevent memory leak, I want to delete unused texture. What is the proper way to do it?

Let's say I created texture :

 

var button = PIXI.Texture.fromCanvas(canvas);

 

Later in the code i want to do something like this :

 

button.destroy(); // really delete texture from memory

button = PIXI.Texture.fromCanvas(canvas); //  newly created texture

 

Thanks in advance,

PIXI.Texture has a destroy method that will remove it from the WebGL memory (source: https://github.com/GoodBoyDigital/pixi.js/blob/master/src/pixi/textures/Texture.js#L78).

 

You probably want this:

var button = PIXI.Texture.fromCanvas(canvas);button.destroy(true); // delete this texture, and the base texture

yes exactly, thank you

 

EDIT: i  just tried it on bunny example-1 with no success.

 

function rem() {

   texture.destroy(true);

}

 

i get message :

 

Uncaught TypeError: Object function (width, height, view, transparent) {

// do a catch.. only 1 webGL renderer..

.

.

.

} has no method 'destroyTexture'

 

any idea?

have someone idea, what is causing  error mentioned above? abything that i'm doing wrong?

also, shouldn't be here :
 

PIXI.Text.prototype.destroy = function(destroyTexture)

{

    if(destroyTexture) {

        this.texture.destroy();

    }

};

 

this.texture.destroy(true); ??

I will look into that for you as it should not be throwing errors :/ Thanks for the heads up!
