I am creating a simple dungeon crawler game that has collisions. The code for the Enemy class is such that it should collide with walls and chase after the player character, however it does not chases after the character, it spawns, moves along the x-axis until it collides with a wall and does not change direction nor chase the player
The code for the game as shown below:
` import pygameimport randomimport sysimport mathimport pygame.sprite
