|
||
|
|
A region of the 2D navigation map.
|
||
|
|
</brief_description>
|

<description>
|
||
|
|
A region of the navigation map. It tells the [Navigation2DServer] what can be navigated and what cannot, based on its [NavigationPolygon] resource.
|
||
|
|
By default this node will register to the default [World2D] navigation map. If this node is a child of a [Navigation2D] node it will register to the navigation map of the navigation node.
|
||
|
|
Two regions can be connected to each other if they share a similar edge. You can set the minimum distance between two vertices required to connect two edges by using [method Navigation2DServer.map_set_edge_connection_margin].
|
||
|
|
[b]Note:[/b] Overlapping two regions' polygons is not enough for connecting two regions. They must share a similar edge.
|
||
|
|
The pathfinding cost of entering this region from another region can be controlled with the [member enter_cost] value.
|
||
|
|
[b]Note[/b]: This value is not added to the path cost when the start position is already inside this region.
|
||
|
|
The pathfinding cost of traveling distances inside this region can be controlled with the [member travel_cost] multiplier.

If [code]true[/code] constraints avoidance agent's with an avoidance mask bit that matches with a bit of the [member avoidance_layers] to the navigation polygon. Due to each navigation polygon outline creating an obstacle and each polygon edge creating an avoidance line constrain keep the navigation polygon shape as simple as possible for performance.

[b]Experimental:[/b] This is an experimental feature and should not be used in production as agent's can get stuck on the navigation polygon corners and edges especially at high frame rate.
