Now I’m trying to use molehill to accelerate my collision detection effeciency, and I found out there is a function called setRenderToTexture that I can use. However, when I get a texture from that function, I cannot access pixel data in it. Does anyone knows how to deal with that, or is there another way to use molehill to do such general-purpose computation?
