"Sub-texture" of a RenderTexture?

[lordnoriyuki]

I want a subset of a RenderTexture, but this doesn't seem to work:

var renderTexture = new PIXI.RenderTexture(1024, 1024);// render something into the renderTexturevar newSprite = new PIXI.Sprite(new PIXI.Texture(renderTexture, new Rectangle(0, 0, 240, 240)))// render this newSprite into a stage

The sprite with the sub-rectangle of the texture doesn't get rendered.

 

If I do the following it works fine (whole renderTexture on a sprite):

var newSprite = new PIXI.Sprite(renderTexture)

If I do the following it doesn't render either (whole renderTexture, but a new texture from the renderTexture):

var newSprite = new PIXI.Sprite(new PIXI.Texture(renderTexture))

How do I get a sprite which has a sub texture of an existing RenderTexture?

 

Thanks

here ya goes:

var subTexture = new PIXI.Texture( renderTexture.baseTexture, new PIXI.Rectangle(10,10, 20, 20) )var newSprite = new PIXI.Sprite(subTexture)

You need to use the RenderTextures baseTexture and it should work fine

That doesn't seem to work either:

var imageTexture = PIXI.Texture.fromImage("image.png");

var renderTexture = new PIXI.RenderTexture(1024, 1024);


var imageSprite = new PIXI.Sprite(imageTexture);

    

renderTexture.render(imageSprite);


var subTexture = new PIXI.Texture(renderTexture.baseTexture, new PIXI.Rectangle(0, 0, 1024, 1024));

var subSprite = new PIXI.Sprite(subTexture);


stage.addChild(subSprite);


renderer.render(stage);

Nothing appears. If I change renderTexture.baseTexture to imageTexture, then it works fine.
