Troubleshooting

Problems with player script

Problem	Cause	Solution
Player not moving	CharacterController has not been assigned	Drag your Player object’s CharacterController into the script field in the Inspector
Player not moving	Script not attached to player	Attach the PlayerMove script to your Player GameObject
Sprint not working	Shift key not detected	Ensure the Game window is focused
Player not jumping	Not grounded	Check groundCheck position and groundMask layer
Player keeps falling	Ground not detected	Make sure ground objects are on the correct layer used in groundMask
Player floating slightly above ground	Ground check too high	Lower the groundCheck object slightly below the player
Player falls through floor	CharacterController misconfigured	Check Center, Height, and Radius values
Player not rotating with camera	Movement uses player transform only	Add mouse look script to rotate player/camera
Ground detection inconsistent	Sphere too small	Increase groundDistance slightly (e.g. change 0.4 to 0.5)
Player clips into walls	Controller step offset too high	Lower Step Offset in CharacterController
Console errors (NullReferenceException)	Missing references	Ensure controller and groundCheck are assigned

Problems with Camera Script

Problem	Cause	Solution
Unity error NullReferenceException	Variable expecting assignment is unassigned	Double check you've referenced PlayerBody in the editor
Unity error error cs1002: ';' expected	missing semicolon	find where it's missing and add a semicolon
Unity error cs0103: the name '[variable name]' does not exist in the current context	Misspelled or unknown variable name	Double check spelling of [variable name] to be consistent
cursor not locking to screen automatically	This happens on older versions of Unity	click on game window
cursor not dissapearing	Unity's cursor.lockState isn't causing this automatically	add Cursor.visible = false; on the line above cursor.lockState
