Code/SboxSuperuser/Engine/Bodies/NoclipMoveMode.cs
A PlayerController MoveMode for a superuser tool. Scores max priority so it overrides every other mode, disables the collider and gravity while active, and flies the controller in the eye direction with jump/duck for vertical movement. Restores collider state and gravity when the mode ends.
🐞 UpdateMove ignores the passed-in eyes rotation and uses Controller.EyeAngles instead, so the view rotation the controller hands in is not the one used for flight direction.
🐞 Restore unconditionally sets body.Gravity to true, so a mode active before noclip that had gravity disabled does not get its state back.
