It handles several objects, namely maps, regions and agents. - Maps are made up of regions, which are made of navigation polygons. Together, they define the navigable areas in the 2D 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 [code]edge_connection_margin[/code] to the respective other edge's vertex. - You may assign navigation layers to regions with [method NavigationServer2D.region_set_layers], which then can be checked upon when requesting a path with [method NavigationServer2D.map_get_path]. This allows allowing or forbidding some areas to 2D objects. + Maps are made up of regions, which are made of navigation polygons.

This includes all changes made to maps, regions or agents by navigation related Nodes in the SceneTree or made through scripts. + For two regions to be connected to each other, they must share a similar edge.

This allows allowing or forbidding some areas to 2D 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. [b]Note:[/b] The collision avoidance system ignores regions. Using the modified velocity as-is might lead to pushing and agent outside of a navigable area. This is a limitation of the collision avoidance system, any more complex situation may require the use of the physics engine. 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. @@ -21,6 +23,13 @@ Creates the agent. </description> </method> + <method name="agent_get_map" qualifiers="const"> + <return type="RID" /> + <argument index="0" name="agent" type="RID" /> + <description> + Returns the navigation map [RID] the requested [code]agent[/code] is currently assigned to. + </description> + </method> <method name="agent_is_map_changed" qualifiers="const"> <return type="bool" /> <argument index="0" name="agent" type="RID" /> @@ -35,7 +44,8 @@ <argument index="2" name="method" type="StringName" /> <argument index="3" name="userdata" type="Variant" default="null" /> <description> - Callback called at the end of the RVO process. + Callback called at the end of the RVO process.
