A server interface for low-level 3D navigation access.

NavigationServer3D is the server that handles navigation maps, regions and agents. It does not handle A* navigation from AStar3D.

Maps are divided into regions, which are composed of navigation meshes. Together, they define the navigable areas in the 3D world.

For two regions to be connected to each other, they must share a similar edge. An edge is considered connected to another if both of its two vertices are at a distance less than edge_connection_margin to the respective other edge's vertex.

You may assign navigation layers to regions with region_set_navigation_layers(), which then can be checked upon when requesting a path with map_get_path(). This can be used to allow or deny certain areas for some objects.

To use the collision avoidance system, you may use agents. You can set an agent's target velocity, then the servers will emit a callback with a modified velocity.

This server keeps tracks of any call and executes them during the sync phase. This means that you can request any change to the map, using any thread, without worrying.

 bool agent_get_use_3d_avoidance<>( RID agent=, agent:RID=, ):bool

Returns true if the provided agent uses avoidance in 3D space Vector3(x,y,z) instead of horizontal 2D Vector2(x,y) / Vector3(x,0.0,z).

 Vector3 agent_get_velocity<>( RID agent=, agent:RID=, ):Vector3

Returns the velocity of the specified agent.

 bool agent_has_avoidance_callback<>( RID agent=, agent:RID=, ):bool

Return true if the specified agent has an avoidance callback.

 bool agent_is_map_changed<>( RID agent=, agent:RID=, ):bool

Returns true if the map got changed the previous frame.

 void agent_set_avoidance_callback<>( RID agent=, agent:RID=, Callable callback=, callback:Callable=, ):void

Sets the callback Callable that gets called after each avoidance processing step for the agent. The calculated safe_velocity will be dispatched with a signal to the object just before the physics calculations.

Note: Created callbacks are always processed independently of the SceneTree state as long as the agent is on a navigation map and not freed. To disable the dispatch of a callback from an agent use agent_set_avoidance_callback() again with an empty Callable.

 void agent_set_avoidance_enabled<>( RID agent=, agent:RID=, bool enabled=, enabled:bool=, ):void

If enabled is true, the provided agent calculates avoidance.

 void agent_set_avoidance_layers<>( RID agent=, agent:RID=, int layers=, layers:int=, ):void

 void agent_set_avoidance_priority<>( RID agent=, agent:RID=, float priority=, priority:float=, ):void

Set the agent's avoidance_priority with a priority between 0.0 (lowest priority) to 1.0 (highest priority).

The specified agent does not adjust the velocity for other agents that would match the avoidance_mask but have a lower avoidance_priority. This in turn makes the other agents with lower priority adjust their velocities even more to avoid collision with this agent.

Updates the provided agent height.

 void agent_set_map<>( RID agent=, agent:RID=, RID map=, map:RID=, ):void

Puts the agent in the map.

 void agent_set_max_neighbors<>( RID agent=, agent:RID=, int count=, count:int=, ):void

Sets the maximum number of other agents the agent takes into account in the navigation. The larger this number, the longer the running time of the simulation. If the number is too low, the simulation will not be safe.

 void agent_set_max_speed<>( RID agent=, agent:RID=, float max_speed=, max_speed:float=, ):void

Sets the maximum speed of the agent. Must be positive.

 void agent_set_neighbor_distance<>( RID agent=, agent:RID=, float distance=, distance:float=, ):void

Sets the maximum distance to other agents this agent takes into account in the navigation. The larger this number, the longer the running time of the simulation. If the number is too low, the simulation will not be safe.

Sets the position of the agent in world space.

 void agent_set_radius<>( RID agent=, agent:RID=, float radius=, radius:float=, ):void

 void agent_set_time_horizon_agents<>( RID agent=, agent:RID=, float time_horizon=, time_horizon:float=, ):void

The minimal amount of time for which the agent's velocities that are computed by the simulation are safe with respect to other agents. The larger this number, the sooner this agent will respond to the presence of other agents, but the less freedom this agent has in choosing its velocities. A too high value will slow down agents movement considerably. Must be positive.

 void agent_set_time_horizon_obstacles<>( RID agent=, agent:RID=, float time_horizon=, time_horizon:float=, ):void

The minimal amount of time for which the agent's velocities that are computed by the simulation are safe with respect to static avoidance obstacles. The larger this number, the sooner this agent will respond to the presence of static avoidance obstacles, but the less freedom this agent has in choosing its velocities. A too high value will slow down agents movement considerably. Must be positive.

 void agent_set_use_3d_avoidance<>( RID agent=, agent:RID=, bool enabled=, enabled:bool=, ):void

Sets if the agent uses the 2D avoidance or the 3D avoidance while avoidance is enabled.

If true the agent calculates avoidance velocities in 3D for the xyz-axis, e.g. for games that take place in air, underwater or space. The 3D using agent only avoids other 3D avoidance using agent's. The 3D using agent only reacts to radius based avoidance obstacles. The 3D using agent ignores any vertices based obstacles. The 3D using agent only avoids other 3D using agent's.

If false the agent calculates avoidance velocities in 2D along the xz-axis ignoring the y-axis. The 2D using agent only avoids other 2D avoidance using agent's. The 2D using agent reacts to radius avoidance obstacles. The 2D using agent reacts to vertices based avoidance obstacles. The 2D using agent only avoids other 2D using agent's. 2D using agents will ignore other 2D using agents or obstacles that are below their current position or above their current position including the agents height in 2D avoidance.

 void agent_set_velocity<>( RID agent=, agent:RID=, Vector3 velocity=, velocity:Vector3=, ):void

Sets velocity as the new wanted velocity for the specified agent. The avoidance simulation will try to fulfill this velocity if possible but will modify it to avoid collision with other agent's and obstacles. When an agent is teleported to a new position use agent_set_velocity_forced() as well to reset the internal simulation velocity.

 void agent_set_velocity_forced<>( RID agent=, agent:RID=, Vector3 velocity=, velocity:Vector3=, ):void

Replaces the internal velocity in the collision avoidance simulation with velocity for the specified agent. When an agent is teleported to a new position this function should be used in the same frame. If called frequently this function can get agents stuck.

Sets the navigation map RID for the link.

 void link_set_navigation_layers<>( RID link=, link:RID=, int navigation_layers=, navigation_layers:int=, ):void

Set the ObjectID of the object which manages this link.

 void link_set_start_position<>( RID link=, link:RID=, Vector3 position=, position:Vector3=, ):void

Sets the entry position for this link.

 void link_set_travel_cost<>( RID link=, link:RID=, float travel_cost=, travel_cost:float=, ):void

Sets the travel_cost for this link.

 RID map_create<>():RID

Create a new map.

 void map_force_update<>( RID map=, map:RID=, ):void

This function immediately forces synchronization of the specified navigation map RID. By default navigation maps are only synchronized at the end of each physics frame. This function can be used to immediately (re)calculate all the navigation meshes and region connections of the navigation map. This makes it possible to query a navigation path for a changed map immediately and in the same frame (multiple times if needed).

Due to technical restrictions the current NavigationServer command queue will be flushed. This means all already queued update commands for this physics frame will be executed, even those intended for other maps, regions and agents not part of the specified map. The expensive computation of the navigation meshes and region connections of a map will only be done for the specified map. Other maps will receive the normal synchronization at the end of the physics frame. Should the specified map receive changes after the forced update it will update again as well when the other maps receive their update.

Avoidance processing and dispatch of the safe_velocity signals is unaffected by this function and continues to happen for all maps and agents at the end of the physics frame.

Note: With great power comes great responsibility. This function should only be used by users that really know what they are doing and have a good reason for it. Forcing an immediate update of a navigation map requires locking the NavigationServer and flushing the entire NavigationServer command queue. Not only can this severely impact the performance of a game but it can also introduce bugs if used inappropriately without much foresight.

 Array map_get_agents<>( RID map=, map:RID=, ):Array

Returns the edge connection margin of the map. This distance is the minimum vertex distance needed to connect two edges from different regions.

 int map_get_iteration_id<>( RID map=, map:RID=, ):int

 void parse_source_geometry_data<>():void

Parses the SceneTree for source geometry according to the properties of navigation_mesh. Updates the provided source_geometry_data resource with the resulting data. The resource can then be used to bake a navigation mesh with bake_from_source_geometry_data(). After the process is finished the optional callback will be called.

Note: This function needs to run on the main thread or with a deferred call as the SceneTree is not thread-safe.

Performance: While convenient, reading data arrays from Mesh resources can affect the frame rate negatively. The data needs to be received from the GPU, stalling the RenderingServer in the process. For performance prefer the use of e.g. collision shapes or creating the data arrays entirely in code.

 void query_path<>():void

Queries a path in a given navigation map. Start and target position and other parameters are defined through NavigationPathQueryParameters3D. Updates the provided NavigationPathQueryResult3D result object with the path among other results requested by the query. After the process is finished the optional callback will be called.

 void region_bake_navigation_mesh<>( NavigationMesh navigation_mesh=, navigation_mesh:NavigationMesh=, Node root_node=, root_node:Node=, ):void

Deprecated: This method is deprecated due to core threading changes. To upgrade existing code, first create a NavigationMeshSourceGeometryData3D resource. Use this resource with parse_source_geometry_data() to parse the SceneTree for nodes that should contribute to the navigation mesh baking. The SceneTree parsing needs to happen on the main thread. After the parsing is finished use the resource with bake_from_source_geometry_data() to bake a navigation mesh.

Bakes the navigation_mesh with bake source geometry collected starting from the root_node.

 RID region_create<>():RID

Creates a new region.

 AABB region_get_bounds<>( RID region=, region:RID=, ):AABB

Owned in this context means that one of the region's navigation mesh polygon faces has a possible position at the closest distance to this point compared to all other navigation meshes from other navigation regions that are also registered on the navigation map of the provided region.

If multiple navigation meshes have positions at equal distance the navigation region whose polygons are processed first wins the ownership. Polygons are processed in the same order that navigation regions were registered on the NavigationServer.

Note: If navigation meshes from different navigation regions overlap (which should be avoided in general) the result might not be what is expected.

 void region_set_use_edge_connections<>( RID region=, region:RID=, bool enabled=, enabled:bool=, ):void

If enabled is true, the navigation region will use edge connections to connect with other navigation regions within proximity of the navigation map edge connection margin.

 void set_active<>( bool active=, active:bool=, ):void

Control activation of this server.

 void set_debug_enabled<>( bool enabled=, enabled:bool=, ):void

If true enables debug mode on the NavigationServer.

 PackedVector3Array simplify_path<>( PackedVector3Array path=, path:PackedVector3Array=, float epsilon=, epsilon:float=, ):PackedVector3Array

Returns a simplified version of path with less critical path points removed. The simplification amount is in worlds units and controlled by epsilon. The simplification uses a variant of Ramer-Douglas-Peucker algorithm for curve point decimation.

Path simplification can be helpful to mitigate various path following issues that can arise with certain agent types and script behaviors. E.g. "steering" agents or avoidance in "open fields".

 RID source_geometry_parser_create<>():RID

Creates a new source geometry parser. If a Callable is set for the parser with source_geometry_parser_set_callback() the callback will be called for every single node that gets parsed whenever parse_source_geometry_data() is used.

 void source_geometry_parser_set_callback<>( RID parser=, parser:RID=, Callable callback=, callback:Callable=, ):void

Sets the callback Callable for the specific source geometry parser. The Callable will receive a call with the following parameters:

  • navigation_mesh - The NavigationMesh reference used to define the parse settings. Do NOT edit or add directly to the navigation mesh.

  • source_geometry_data - The NavigationMeshSourceGeometryData3D reference. Add custom source geometry for navigation mesh baking to this object.

  • node - The Node that is parsed.
