Ok so I am new in game development and for simple games bounding box collision is fine. However, let's say you have a shape or bitmap like this:
Now this is just an example but if you had more elaborate curves or even a whole shape which was more complex than a simple polygon or rectangle-like shape, how would you do precise collision detection? And I am strictly speaking in 2D here. I just want to know the concept behind how you would do this. Thanks!
