I have some code which works just fine, but I'm not sure if there's a better way of drawing lines on the screen with a texture-brush and I also have a question about erasing Here's what I'm doing atm: SETUP Create a RenderTexture of a certain size ("renderTexture") Create a Sprite out of that, and add the Sprite to the stage ("viewSprite") Create a Container, don't add anything to it yet ("drawBuffer") Create an Array (or really object pool "pool") of sprites
