Please use Code tags for your code.
[SerializeField] private RigidBodyMovement PlayerBody;
There’s no such thing as RigidBodyMovement. Replace it with Rigidbody instead.
Apart from this… it’s never a good idea to just copy some code from somewhere if you don’t fully understand C# yet. There are various tutorials and courses about it, though, so… instead of trying hard to create a game at all cost, maybe learn programming first? Just saying because all of your previous threads are simply “you getting hit by errors here and there”.
