Struct NavigationPolygon
A node that has methods to draw outlines or use indices of vertices to create navigation polygons.
struct NavigationPolygon
;
There are two ways to create polygons. Either by using the addOutline
method, or using the addPolygon
method.
Using addOutline
:
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
Using addPolygon
and indices of the vertices array.
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, 3, 1)
polygon.add_polygon(indices)
$NavigationPolygonInstance.navpoly = polygon

|
addOutline
|
Appends a PoolVector2Array that contains the vertices of an outline to the internal array that contains all the outlines. You have to call makePolygonsFromOutlines in order for this array to be converted to polygons that the engine will use.
|
addOutlineAtIndex
|
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 makePolygonsFromOutlines in order for this array to be converted to polygons that the engine will use.
|
addPolygon
|
Adds a polygon using the indices of the vertices you get when calling getVertices .
|
clearOutlines
|
Clears the array of the outlines, but it doesn't clear the vertices and the polygons that were created by them. |
clearPolygons
|
Clears the array of polygons, but it doesn't clear the array of outlines and vertices. |
getOutline
|
Returns a PoolVector2Array containing the vertices of an outline that was created in the editor or by script.
|
getOutlineCount
|
Returns the number of outlines that were created in the editor or by script. |
getPolygon
|
Returns a PoolIntArray containing the indices of the vertices of a created polygon.
|
getPolygonCount
|
Returns the count of all polygons. |
getVertices
|
Returns a PoolVector2Array containing all the vertices being used to create the polygons.
|
makePolygonsFromOutlines
|
Creates polygons from the outlines added in the editor or by script. |
removeOutline
|
Removes an outline created in the editor or by script. You have to call makePolygonsFromOutlines for the polygons to update.
|
setOutline
|
Changes an outline created in the editor or by script. You have to call makePolygonsFromOutlines for the polygons to update.
|
setVertices
|
Sets the vertices that can be then indexed to create polygons with the addPolygon method.
