Add controller support to PR #22

Fixed camera jitter

README.md

@@ -33,7 +33,7 @@ You can make this a super basic controller by just disabling everything.
 - In the controls export group, there is a commented section at the end that says "Uncomment this if you want full controller support". Uncomment that block.
 - Make a key map for each direction (left, right, up, down) and map them to your joystick.
 - Write in these keymaps in the controls section of the player settings.
-- In the `_process` function, there is another block of commented code at the end that says the same thing. Uncomment that too.
+- In the `handle_head_rotation` function, there is another block of commented code that says the same thing. Uncomment that too.
 - You should now be able to look around with the joystick. Make sure you add the other controls to the input map. (movement, jumping, crouching, sprinting, etc.)
