SKSpriteNode stretching when manually animating textures

Question

I have a fairly simple animation with 8 identically sized images. I'm not using the built in animation methods as I want to manually control the speed of the animation on the fly. I'm using preloaded SKTexture's and doing [object setTexture:texture]; inside of the update:currentTime method. The problem is that sometimes the texture gets really distorted/stretched. After a lot of debugging, I have narrowed it down to only happening when the node is stationary. In fact, if I move the node a pixel and move it back like this, the problem never occurs: ``` [self setTexture:texture]; CGPoint currentPosition = self.position; self.position = CGPointMake(currentPosition.x + 1, currentPosition.y + 1); self.position = currentPosition; ``` This feels extremely hacky to me. I think under the hood, it's triggering a redraw on the parent node. Has anyone else experienced this? I have two major questions. 1) What is the cause? and 2) How can I resolve this without resorting to a hack? Here is a norma…

Accepted Answer

It seems that upon setting the texture using setTexture: sprite node doesn't change it size, until being moved, resized, etc...

You can resolve this by manually setting the size after setting the texture.

```
[spriteNode setTexture:texture];
[spriteNode setSize:texture.size];
```
