Pausing/ Unpausing In Pygame

This is the part of mine snake game code that I'm trying to change so I can pause, I'm managing to pause with it, but I'm failing in unpausing(the game freezes), I'm trying to use

Solution 1:

Don't use while but variable paused = True to control functions which move object

paused = FalsewhileTrue:

    foreventin pygame.event.get()

          ifevent.key == pygame.K_p: # Pausing
              paused = Trueifevent.key == pygame.K_u:  # Unpausing
              paused = Falseifnot paused:
        player.move()
        enemy.move()

If you want to use one key to pause/unpause

ifevent.key == pygame.K_p: # Pausing/Unpausing
        paused = not paused

Solution 2:

Furas's method works well, but here is an alternate method that you could use when your project grows larger.

Effectively you set an attribute called self.toggle on your sprites, and only when that toggle attribute if False and a key is pressed is when your player can move. When the key to pause is pressed, self.toggle becomes True and you cannot move anymore.

E.x:

classThing():
    self.toggle = True# Some lines later...if event.key == pygame.K_LEFT andnot thingsprite.toggle:
    # Move Code here# Some lines laterif keys[pygame.K_TAB]:
    thingsprite.toggle = True# Therefore thingsprite cannot move left anymore# Alt method if you have more than one spritefor sprite in spritegroup:
         sprite.toggle = True
