Wall Collision Logic | Pac-Man in Python – Ep. 5 (Beginner Tutorial Series)

💥 *Wall Collision Logic | Pac-Man in Python – Ep. 5 (Beginner Tutorial Series)*

In this episode, we give Pac-Man a sense of awareness — by adding *wall collision detection* to the game using *Python* & the *Turtle Graphics* module.

We’ll create a reliable system that checks whether Pac-Man is about to hit a wall, and stop him just in time to keep him inside the maze. You’ll also learn how to align his position to the grid using *collision correction logic* making turns feel clean and responsive — even when the player moves early or late.

By the end of this episode, Pac-Man will move naturally through the maze, bounce off walls, and snap into place when turning — just like in the original arcade game. You’ll be ready to implement pellet collection and user interface in Episode 6.

*You’ll learn how to:*
• 🔎 Detect collisions by checking Pac-Man’s position and direction
• 🧠 Compare his edges to wall tile locations
• ➕ Add correction logic for smoother turning and movement control
• 🧱 Build grid-aware collision detection in Python Turtle
