How to Create these simple holes in a NavigationPolygon by using GDscript?
Here’s the link for the Image if it wouldn’t show up

I have a script that creates a NavigationPolygon. It works without a problem. Also, I got a script for generating these holes but I can’t manage it to create these holes.

  1. The script first creates a polygon:
`var Polygon = PoolVector2Array([

Vector2(-worldsize, -worldsize),
Vector2(worldsize, -worldsize),
Vector2(worldsize, worldsize),
Vector2(-worldsize, worldsize)])`

  1. Then it creates another polygon for the hole:
`var hole = PoolVector2Array([

Vector2(-50, -50),
Vector2(50, -50),
Vector2(50, 50),
Vector2(-50, 50)])`

  1. Then it needs to combine somehow these polygons to cut out the hole, but i simply dont know how.

I know about the godot-clipper by Xrayez but I don’t have a clue how to properly install it :frowning:

Then you do like this:

Polygon.add_outline(hole)
Polygon.make_polygons_from_outlines()
