Collision Detection Not Working - PyGame

Question

I'm working in a game, and in this game an object falls from the top of the game screen and the player at the bottom of the screen has to hit the object falling. When the player hits the falling object, the player's width and height needs to increase. When I tested the code, the collision worked when the player hit the falling object from the side, but the collision didn't work when the player hit the falling object in the middle. Can someone help me?

Answer 1

The problem was that had to minus the player's width

Before:

if self.y >= player.y and self.y <= player.y + player.h and self.x >= player.x and self.x <= player.x + player.w:
            player.w += player.increase
            player.h += player.increase
            player.y - player.increase

After:

if self.y >= player.y - player.h and self.y <= player.y + player.h and self.x >= player.x - player.w and self.x <= player.x + player.w:
            player.w += player.increase
            player.h += player.increase
            player.y - player.increase

I forgot that the objects x and y start at the top left.
