Adding a Third Person Camera

1. Visualizing the Player – Just a ball for now.

• The player's facing direction using a debug line.

2. Implemented a 3rd person follow camera.

• Keeping the player in the view.

• The camera does not clip through the world geometry.

• No abrupt transitions. Smooth lerp towards and away from player.

3. Made the player's input control view-relative - Pushing the 'forward' button makes the player go away from the camera, regardless of which way the player is facing.

WASD to move the player.

~ to open the debug menu.

UHJK to move the camera in FLY mode and arrow keys to rotate.
