Problems with translating player to center at screen

Processing.py
1

i am working on a program with the player translated to the center of screen and the background moving around the player. I have working collision detection- when the player hits any of the blocks on the screen, it stops. For example, when the player hits a block while going up, its only choice is to go down. But I would like that the player be able to go left and right.

Player Movement:

                cMove = False
            
        if cMove:

What if you used four different cMove variables? A cMoveUp, cMoveDown, cMoveRight, cMoveLeft.

Use separate functions to check if different moves are valid?
