Hi Everyone

Has anyone ever had problems with collision tests between circles/squares or irregular shaped objects?

What I mean by collision is precise contact between each object. I.e. when the objects touch each other exactly (not with a gap in between).

Any does anyone know any good tutorials that I can check out to get some ideas 🙂

Thanks in advance :thumb:
