Just a picture post!

Lots of collisions here with explosions turned offIn the chapter 42 of both e-books when the first collision detection is introduced, I added a SHOWOVERLAP #define. If this is uncommented, instead of things blowing up, it shows every pixel where two objects pixel’s overlap in bright green.

In the picture above you can see the player ship in the centre and all those green bits where things overlap. You don’t normally see this and it is so intensive that it drops the frame rate from the usual 60 fps to about 3 or 4. But I think it’s quite cool!
