FBO's and Collision detection recommendations

Hi!

I’m working on a little game where I want to do pixel based collision detection.

There are several objects moving around, each one of them with a “footprint.png” associated which is the area where the character cannot step.

I was planning to use FBO’s to put together all the footprints in a single image and then check if the character is over a “black pixel”, everything offscreen

Do you think that this is a good approach?

Thank you!

sounds like a good plan to me
