Resize a texture in a sprite

[Akis]

Hi,

 

In my project, I created a sprite using a "default" texture, then later I'd like to replace the texture by another one but this one could have a different size than the default, so I need a way to resize the texture. Could you tell me the way to do it?

 

I create my new texture using PIXI.Texture.fromImage and then I switch the texture with setTexture

[Akis]

This function doesn't seem to be fired when I update the texture...

/** * When the texture is updated, this event will fire to update the scale and frame */PIXI.Sprite.prototype.onTextureUpdate

Ok, I see the sprite listens the update event of the texture, but if I change the texture with setTexture, it will never listen the events from the new texture...

Ok, I resolved this by manually listening to the update event

var that = this,    texture = PIXI.Texture.fromImage(imageUrl, true);var textureUpdated = function () {    texture.off('update', textureUpdated);    // rescale the image    that.mSprite.onTextureUpdate(); };texture.on( 'update', textureUpdated);this.mSprite.setTexture(texture);

In my case, I won't exactly use onTextureUpdate as I need to keep the ratio of the image when I scale it. But I think the lib should already do that by default when we change the texture.

Even with a cache texture, it's weird to have to do this.

sprite.setTexture(PIXI.TextureCache['frame1']);sprite.onTextureUpdate();

HI there Akis!

 

Thanks for sharing your issue. This indeed looks like a bug :/ 

It should be that onTextureUpdate gets called automatically, but looks like something is not ticking over correctly there. I will make sure to take a look into that for you.

 

Cheers!
