Look at the video :
- I create a NavigationPolygonInstance in the scene
- In the inspector, I create a new NavigationPolygon in field "navPoly"
- No matter what mode I choose (by clicking the buttons for editing points: Create points, Edit points, Delete points), then clicking inside the scene does not add any new point. It only drags the scene around.
I can effectively not create a polygon.
It's my first time using Godot. Am I completely misunderstanding the UI for placing points?
