Updated basic fps and tps controllers for Godot 3.x and 4.0.
Features include:
-basic movement and jumping
-physics interpolation to reduce jitter on high refresh rate monitors
-solves all weird slope sliding/climbing issues
Suggestions:
-attach FPS.gd to the main node (kinematic body) of FPS.tscn
-attach TPS.gd to the main node (kinematic body) of TPS.tscn
-names for wasd keybindings are "move_forward" "move_backward" "move_left" and "move_right"
-this is just a character controller, I assume you already have a game world set up to test it out on
