There are two ways to create polygons. Either by using the [method add_outline] method or using the [method add_polygon] method.
Using [method add_outline]:

var polygon = NavigationPolygon.new()
var outline = PoolVector2Array([Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)])
polygon.add_outline(outline)

Appends a [PoolVector2Array] that contains the vertices of an outline to the internal array that contains all the outlines. You have to call [method make_polygons_from_outlines] in order for this array to be converted to polygons that the engine will use.
