Godot Navigation | Subtracting Collision Shapes from Navigation Polygons

In this Godot Tutorial, I will teach you how you can make pathing through the use of the Godot Navigation2D node smoother by subtracting any collision shape from the navigationpolygon, thereby avoiding the collision objects altogether.

00:15 Introduction 03:06 Subtracting StaticBody Collision Shapes 08:41 Subtracting TileMap Collision Shapes 19:46 Limitations of this Solution 22:43 A Bright Future in Godot 4.0

The solution in this tutorial is not perfect as you can't remove outlines that share vertice locations. For a perfect solution, we will have to wait for the NavigationServer that will be introduced in Godot 4.0.
