‘Hi there ! I wrote this code to create a snake sport. For now it isn’t completed but . The largest drawback is that I dont know the right way to transfer the snake easily and by that I imply to maneuver the snake simply by 1 block . Now once I transfer the snake it strikes with the entire physique . ‘
