Is there a good way to get pixel-perfect collision detection in XNA?
- by ashes999
Is there a well-known way (or perhaps reusable bit of code) for pixel-perfect collision detection in XNA?
I assume this would also use polygons (boxes/triangles/circles) for a first-pass, quick-test for collisions, and if that test indicated a collision, it would then search for a per-pixel collision.
This can be complicated, because we have to account for scale, rotation, and transparency.
WARNING: If you're using the sample code from the link from the answer below, be aware that the scaling of the matrix is commented out for good reason. You don't need to uncomment it out to get scaling to work.
