Falling blocks – shooting game

Concept:

I tried to create a first person shooter game with falling blocks that would result in a point when shot .

What went well :

I learned how to use OOP more effectively for both the falling blocks and bullets. I successfully attached a hardware component

What didn’t:

Games are not my strong suit as I couldn’t find a way to make collision detection work in this case.

Took a lot of code to write but couldn’t finish the collision detection.

How to improve:

Either choose a game that doesn’t involve collision detection or work on collision detection first.
