NavigationRegion3D

Inherits: Node3D < Node < Object

A traversable 3D region that NavigationAgent3Ds can use for pathfinding.

Description

A traversable 3D region based on a NavigationMesh that NavigationAgent3Ds can use for pathfinding.

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 NavigationServer3D.map_set_edge_connection_margin.

Note: Overlapping two regions' navigation meshes is not enough for connecting two regions. They must share a similar edge.

The cost of entering this region from another region can be controlled with the enter_cost value.

Note: This value is not added to the path cost when the start position is already inside this region.

The cost of traveling distances inside this region can be controlled with the travel_cost multiplier.

Note: This node caches changes to its properties, so if you make changes to the underlying region RID in NavigationServer3D, they will not be reflected in this node's properties.

Signals

bake_finished ( )

Notifies when the navigation mesh bake operation is completed.

---

navigation_mesh_changed ( )

Notifies when the NavigationMesh has changed.

Property Descriptions

bool enabled = true

• void set_enabled ( bool value )

• bool is_enabled ( )

Determines if the NavigationRegion3D is enabled or disabled.

---

float enter_cost = 0.0

• void set_enter_cost ( float value )

• float get_enter_cost ( )

When pathfinding enters this region's navigation mesh from another regions navigation mesh the enter_cost value is added to the path distance for determining the shortest path.
