We don't use that info for anything, and it generates unnecessary diffs every time we bump the minor version (and CI failures if we forget to sync some files from opt-in modules (mono, text_server_fb).

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]:
|
|
[codeblocks]
|
|
[gdscript]
|
|
var polygon = NavigationPolygon.new()
|
|
var outline = PackedVector2Array([Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)])
|
|
polygon.add_outline(outline)
|
|
polygon.make_polygons_from_outlines()
|
|
$NavigationRegion2D.navigation_polygon = polygon
|
|
[/gdscript]
|
|
[csharp]
|
|
var polygon = new NavigationPolygon();
|
|
var outline = new Vector2[] { new Vector2(0, 0), new Vector2(0, 50), new Vector2(50, 50), new Vector2(50, 0) };
|
|
polygon.AddOutline(outline);
|
|
polygon.MakePolygonsFromOutlines();
|
|
GetNode<NavigationRegion2D>("NavigationRegion2D").NavigationPolygon = polygon;
|
|
[/csharp]
|
|
[/codeblocks]
|
|
Using [method add_polygon] and indices of the vertices array.
|
|
[codeblocks]
|
|
[gdscript]
|
|
var polygon = NavigationPolygon.new()
|
|
var vertices = PackedVector2Array([Vector2(0, 0), Vector2(0, 50), Vector2(50, 50), Vector2(50, 0)])
|
|
polygon.vertices = vertices
|
|
var indices = PackedInt32Array([0, 1, 2, 3])
|
|
polygon.add_polygon(indices)
|
|
$NavigationRegion2D.navigation_polygon = polygon
|
|
[/gdscript]
|
|
[csharp]
|
|
var polygon = new NavigationPolygon();
|
|
var vertices = new Vector2[] { new Vector2(0, 0), new Vector2(0, 50), new Vector2(50, 50), new Vector2(50, 0) };
|
|
polygon.Vertices = vertices;
|
|
var indices = new int[] { 0, 1, 2, 3 };
|
|
polygon.AddPolygon(indices);
|
|
GetNode<NavigationRegion2D>("NavigationRegion2D").NavigationPolygon = polygon;
|
|

<method name="add_outline">

<return type="void" />
|

<param index="0" name="outline" type="PackedVector2Array" />
|
|
<description>
|
|
Appends a [PackedVector2Array] 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.

<description>
|
|
Adds a [PackedVector2Array] 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.

|
|
<description>
|
|
Adds a polygon using the indices of the vertices you get when calling [method get_vertices].

</method>
|
|
<method name="clear_outlines">
|
|
<return type="void" />
|
|
<description>
|
|
Clears the array of the outlines, but it doesn't clear the vertices and the polygons that were created by them.

|
|
<method name="clear_polygons">
|

<return type="void" />

<description>
|
|
Clears the array of polygons, but it doesn't clear the array of outlines and vertices.

</method>
|
|
<method name="get_navigation_mesh">
|
|
<return type="NavigationMesh" />
|
|
<description>
|
|
Returns the [NavigationMesh] resulting from this navigation polygon. This navigation mesh can be used to update the navigation mesh of a region with the [method NavigationServer3D.region_set_navigation_mesh] API directly (as 2D uses the 3D server behind the scene).
