Overview ¶
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.MapSetEdgeConnectionMargin.
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 EnterCost 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 TravelCost multiplier.
Note: This node caches changes to its properties, so if you make changes to the underlying region Resource.ID in NavigationServer3D, they will not be reflected in this node's properties.

Types ¶
type Advanced ¶
type Advanced = class
Advanced exposes a 1:1 low-level instance of the class, undocumented, for those who know what they are doing.
type Extension ¶
Extension can be embedded in a new struct to create an extension of this class. T should be the type that is embedding this Extension
func (*Extension[T]) AsNavigationRegion3D ¶
type ID ¶
ID is a typed object ID (reference) to an instance of this class, use it to store references to objects with unknown lifetimes, as an ID will not panic on use if the underlying object has been destroyed.
type Instance ¶
type Instance [1]gdclass.NavigationRegion3D
Instance of the class with convieniently typed arguments and results.
var Nil Instance
Nil is a nil/null instance of the class. Equivalent to the zero value.
func (Instance) AsNavigationRegion3D ¶
func (Instance) BakeNavigationMesh ¶
func (self Instance) BakeNavigationMesh()
Bakes the NavigationMesh. If 'on_thread' is set to true (default), the baking is done on a separate thread. Baking on separate thread is useful because navigation baking is not a cheap operation. When it is completed, it automatically sets the new NavigationMesh. Please note that baking on separate thread may be very slow if geometry is parsed from meshes as async access to each mesh involves heavy synchronization. Also, please note that baking on a separate thread is automatically disabled on operating systems that cannot use threads (such as Web with threads disabled).
func (Instance) Enabled ¶
Determines if the NavigationRegion3D is enabled or disabled.
func (Instance) EnterCost ¶
When pathfinding enters this region's navigation mesh from another regions navigation mesh the EnterCost value is added to the path distance for determining the shortest path.
func (Instance) GetBounds ¶
func (self Instance) GetBounds() AABB.PositionSize
Returns the axis-aligned bounding box for the region's transformed navigation mesh.
func (Instance) GetNavigationLayerValue ¶
Returns whether or not the specified layer of the NavigationLayers bitmask is enabled, given a 'layer_number' between 1 and 32.
func (Instance) GetNavigationMap ¶
func (self Instance) GetNavigationMap() RID.NavigationMap3D
Returns the current navigation map Resource.ID used by this region.
func (Instance) GetRegionRid ¶
func (self Instance) GetRegionRid() RID.NavigationRegion3D
Returns the Resource.ID of this region on the NavigationServer3D.
func (Instance) GetRid ¶
func (self Instance) GetRid() RID.NavigationRegion3D
Returns the Resource.ID of this region on the NavigationServer3D. Combined with NavigationServer3D.MapGetClosestPointOwner can be used to identify the NavigationRegion3D closest to a point on the merged navigation map.
func (Instance) IsBaking ¶
Returns true when the NavigationMesh is being baked on a background thread.
func (Instance) MoreArgs ¶
MoreArgs enables certain functions to be called with additional 'optional' arguments.
func (Instance) NavigationLayers ¶
A bitfield determining all navigation layers the region belongs to. These navigation layers can be checked upon when requesting a path with NavigationServer3D.MapGetPath.
func (Instance) NavigationMesh ¶
func (self Instance) NavigationMesh() NavigationMesh.Instance
The NavigationMesh resource to use.
func (Instance) OnBakeFinished ¶
Notifies when the navigation mesh bake operation is completed.
func (Instance) OnNavigationMeshChanged ¶
Notifies when the NavigationMesh has changed.
func (Instance) SetEnabled ¶
SetEnabled sets the property returned by [IsEnabled].
func (Instance) SetEnterCost ¶
SetEnterCost sets the property returned by [GetEnterCost].
func (Instance) SetNavigationLayerValue ¶
Based on 'value', enables or disables the specified layer in the NavigationLayers bitmask, given a 'layer_number' between 1 and 32.
func (Instance) SetNavigationLayers ¶
SetNavigationLayers sets the property returned by [GetNavigationLayers].
func (Instance) SetNavigationMap ¶
func (self Instance) SetNavigationMap(navigation_map RID.NavigationMap3D)
Sets the Resource.ID of the navigation map this region should use. By default the region will automatically join the World3D default navigation map so this function is only required to override the default map.
func (Instance) SetNavigationMesh ¶
func (self Instance) SetNavigationMesh(value NavigationMesh.Instance)
SetNavigationMesh sets the property returned by [GetNavigationMesh].
func (Instance) SetTravelCost ¶
SetTravelCost sets the property returned by [GetTravelCost].
func (Instance) SetUseEdgeConnections ¶
SetUseEdgeConnections sets the property returned by [GetUseEdgeConnections].
func (Instance) TravelCost ¶
When pathfinding moves inside this region's navigation mesh the traveled distances are multiplied with TravelCost for determining the shortest path.
func (Instance) UseEdgeConnections ¶
If enabled the navigation region will use edge connections to connect with other navigation regions within proximity of the navigation map edge connection margin.
type MoreArgs ¶
type MoreArgs [1]gdclass.NavigationRegion3D
MoreArgs is a container for Instance functions with additional 'optional' arguments.
func (MoreArgs) BakeNavigationMesh ¶
Bakes the NavigationMesh. If 'on_thread' is set to true (default), the baking is done on a separate thread. Baking on separate thread is useful because navigation baking is not a cheap operation. When it is completed, it automatically sets the new NavigationMesh. Please note that baking on separate thread may be very slow if geometry is parsed from meshes as async access to each mesh involves heavy synchronization. Also, please note that baking on a separate thread is automatically disabled on operating systems that cannot use threads (such as Web with threads disabled).
