Here are some questions that might be on your mind:

Q) Are there any better ways of doing collision detection?

A) Yes. There are lots more ways to do collision detection, including but not limited to the following:

• You can divide objects into multiple rectangles which better fit the shape of the sprite. It is perfectly manageable for C++ to check on thousands of rectangles each frame. This is especially true when you use techniques such as neighbor checking to reduce the number of tests that are necessary each frame.
• For circular objects, you can use the radius overlap method.
• For irregular polygons, you can use the crossing number algorithm.

  All these techniques can be investigated at the following website:
