A node that has methods to draw outlines or use indices of vertices to create navigation polygons.

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]:
|
|
[codeblock]
|
|
var polygon = NavigationPolygon.new()
|
|
var outline = PoolVector2Array([Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)])
|
|
polygon.add_outline(outline)
|
|
polygon.make_polygons_from_outlines()
|
|
$NavigationPolygonInstance.navpoly = polygon
|
|
[/codeblock]
|
|
Using [method add_polygon] and indices of the vertices array.
|
|
[codeblock]
|
|
var polygon = NavigationPolygon.new()
|
|
var vertices = PoolVector2Array([Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)])
|
|
polygon.set_vertices(vertices)
|
|
var indices = PoolIntArray([0, 1, 2, 3])
|
|
polygon.add_polygon(indices)
|
|
$NavigationPolygonInstance.navpoly = polygon
|
|
[/codeblock]

<description>
|
|
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.

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