Third person controller without dedicated physics engine

A short clip showing third person controller in Godot Engine **without** using physics body/features. Using build-in navigation features to define the walkable area and move the player by maniputaing it's position. Using geometry check to avoid camera clipping into the walls/ground replicating the feature of **SpringArm3D** of Godot.
