用於存取低階 2D 導覽的伺服器介面。
說明
NavigationServer2D is the server that handles navigation maps, regions and agents. It does not handle A* navigation from AStar2D or AStarGrid2D.
Maps are divided into regions, which are composed of navigation polygons. Together, they define the traversable areas in the 2D world.
Note: Most NavigationServer2D changes take effect after the next physics frame and not immediately. This includes all changes made to maps, regions or agents by navigation-related nodes in the scene tree or made through scripts.
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.
Note: The collision avoidance system ignores regions. Using the modified velocity directly may move an agent outside of the traversable 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.

void agent_set_avoidance_callback(agent: RID, callback: Callable) 🔗
設定在 agent 的每個避障處理步驟之後呼叫的回呼函式 Callable。計算出的 safe_velocity 將在物理計算之前通過訊號發送。
注意：只要代理還在導覽地圖上且未被釋放，建立的回呼函式就會始終獨立於 SceneTree 狀態進行處理。要為某個代理禁用回呼函式的發送，請再次使用一個空的 Callable 來呼叫 agent_set_avoidance_callback()。
void agent_set_avoidance_enabled(agent: RID, enabled: bool) 🔗
如果 enabled 為 true，則指定的 agent 使用避障。
void agent_set_avoidance_layers(agent: RID, layers: int) 🔗

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.

void agent_set_neighbor_distance(agent: RID, distance: float) 🔗

考慮其他代理的前提下，該代理的速度的最短安全時間，這個速度是通過模擬得到的。數值越大，代理回應其他代理的速度就越快，但該代理選擇速度的自由度也就越小。太高的取值會大大降低代理的移動速度。必須為正數。

考慮其他靜態避障障礙物的前提下，該代理的速度的最短安全時間，這個速度是通過仿真得到的。數值越大，代理回應存在的靜態避障障礙物的速度就越快，但該代理選擇速度的自由度也就越小。太高的取值會大大降低代理的移動速度。必須為正數。
void agent_set_velocity(agent: RID, velocity: Vector2) 🔗
將 velocity 設定為指定代理 agent 的新的需求速度。避障模擬會盡可能嘗試滿足這個速度，但為了躲避與其他代理和障礙物的碰撞也會對它進行修改。將代理傳送至新的較遠的位置時，請改用 agent_set_velocity_forced() 重設內部速度狀態。
void agent_set_velocity_forced(agent: RID, velocity: Vector2) 🔗
將指定代理 agent 的避障模擬內部速度替換為 velocity。將代理傳送至新的較遠的位置時，應該在同一影格裡使用這個函式。頻繁呼叫這個函式可能讓代理卡住。
void bake_from_source_geometry_data(navigation_polygon: NavigationPolygon, source_geometry_data: NavigationMeshSourceGeometryData2D, callback: Callable = Callable()) 🔗

void map_force_update(map: RID) 🔗
已棄用： This method is no longer supported, as it is incompatible with asynchronous updates. It can only be used in a single-threaded context, at your own risk.
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.
