How I Make My Python Code Delete The Pills From My Pac Man Game?

My code for Pac-Man make all the cells switch, so when I pass Pac-Man through the pills, he doesn't eat it, just ignore them and change position. I want the pills to disappear when

Solution 1:

You have to define a number for the "empty" fields. In the following I use -1 for the fields visited by the player.

Change the method trocar_celulas. Replace a field that is 0 with -1

class Tabuleiro:
    # [...]

    def trocar_celulas(self, row1, col1, row2, col2):
        if self.validar_col(row1, col1) and self.validar_col(row2, col2):
            if self.maze[row1][col1] == 0:
                 self.maze[row1][col1] = -1
            if self.maze[row2][col2] == 0:
                 self.maze[row2][col2] = -1
            self.maze[row1][col1], self.maze[row2][col2] = self.maze[row2][col2], self.maze[row1][col1]

You must allow the player to move to fields that are 0 and -1:

jogo = True
while jogo:
    # [...]

     if pygame.key.get_pressed()[K_LEFT]:
        if maze.numero(row, col - 1, 0) or maze.numero(row, col - 1, -1):
            maze.trocar_celulas(row, col - 1, row, col)
    if pygame.key.get_pressed()[K_RIGHT]:
        if maze.numero(row, col + 1, 0) or maze.numero(row, col + 1, -1):
            maze.trocar_celulas(row, col + 1, row, col)
    if pygame.key.get_pressed()[K_UP]:
        if maze.numero(row - 1, col, 0) or maze.numero(row - 1, col, -1):
            maze.trocar_celulas(row - 1, col, row, col)
    if pygame.key.get_pressed()[K_DOWN]:
        if maze.numero(row + 1, col, 0) or maze.numero(row + 1, col, -1):
            maze.trocar_celulas(row + 1, col, row, col)
