Game development often requires being able to detect more information than just, “two objects are overlapping”. We need to know how much they are overlapping, where they are overlapping, and what types of objects they are. We need to process this quickly, for games where hundreds of objects could be overlapping at any given point. And we need to calculate how the objects should respond to this overlap: should they bounce, slide, or explode?
