Bro using this code in godot 4 the player just fips down starts to roll how can i fix it

Turn on Deactivation -> Lock Rotation in the properties for the base player object

whatever I do, ANYTHING I do I keep getting errors in lines 39 and 40!!! >⌓<

Script inherits from native type 'RigidBody3D', so it can't be assigned to an object of type: 'MeshInstance3D'

I have fixed the problem with the error on the lines heres the new code script if anyone wants it.

Could you copy paste it

i got really annoyed by the fact that you cant set the mouse mode back to captured once you turned it visible so here is a little fix for that
