Pygame Pacman - Enemy Random Movement

Ive made a pacman game using python and pygame and I have one of the ghosts that just makes random movements around the maze. Does anyone know if there is a way for me to make the

Solution 1:

A possible improvement could be to keep the direction for a certain distance. Add an attribute for the current direction and number of steps. Keep the direction as long as there are steps left and the enemy doesn't hit a wall:

class Enemy:
    def __init__(self):
        # [...]

        self.dir = (0, 0)
        self.steps = 0

    def get_random_direction(self):
        self.steps -= 1
        if self.steps > 0:
            next_pos = vec(self.grid_pos.x + self.dir[0], self.grid_pos.y + self.dir[1])
            if next_pos not in self.app.walls:
                return vec(self.dir)

        possible_directions = []
        for dir_x, dir_y in [(1, 0), (0, 1), (-1, 0), (0, -1)]:
            next_pos = vec(self.grid_pos.x + dir_x, self.grid_pos.y + dir_y)
            if next_pos not in self.app.walls:
                possible_directions.append((dir_x, dir_y))

        self.steps = random.randint(3, 10)
        self.dir = random.choice(possible_directions)
        return vec(self.dir)
