Hello! I'm a greenie. I was trying to figure out how to get some nice feeling movement in my new project, but I just can't get the dang thang to work! I've tried everything short of what is currently out of my knowledge scope for vector math and quats. I've got it to turn towards the walk direction but that's about it... Any help would be much appreciated! c:
Here is my player node tree if that needed.

My player script so far:
extends KinematicBody
export var _gravity := 30.0
export var _jump_strength := 10.0
export var _rotation_speed := 10.0
export var _acceleration_on := false
export var _speed := 6.0
export(float, 0.05, 1.0) var tilt := 0.3
