使用 NavigationAgent

NavigationAgent 是協助節點，結合了路徑尋找、路徑跟隨與代理體迴避等功能，可加掛於 Node2D／Node3D 類型的父節點。它們以更直觀的方式，協助父角色節點呼叫 NavigationServer API，對初學者特別友善。

NavigationAgent 有 2D 與 3D 版本，分別為 NavigationAgent2D 與 NavigationAgent3D。

新的 NavigationAgent 節點會自動加入 World2D／World3D 的預設導航地圖。

NavigationAgent 節點為選用元件，並非使用導航系統的必要條件。其所有功能皆可透過腳本直接呼叫 NavigationServer API 實作。

小訣竅

若需更進階的用法，請考慮使用使用 NavigationPathQueryObject，而非僅使用 NavigationAgent 節點。

NavigationAgent 尋路

當 NavigationAgent 的 target_position 設定為全域座標時，會在目前的導航地圖上查詢新的路徑。

尋路結果可由下列屬性影響。

navigation_layers 位元遮罩可用來限制代理體可使用的導航網格。
pathfinding_algorithm 控制尋路演算法在導航網格多邊形中的搜尋方式。
path_postprocessing 設定是否、以及如何對尋路找到的原始路徑走廊進行後處理。
path_metadata_flags 允許收集路徑點額外的元資料。
simplify_path 與 simplify_epsilon 屬性可用來簡化路徑，移除不重要的路徑節點。

警告

如果關閉路徑元資料旗標，代理體將不會發出相關訊號。

NavigationAgent 路徑跟隨

當代理體設定了 target_position 後，可透過 get_next_path_position() 取得路徑上的下一個要跟隨的位置。

取得下一個路徑位置後，請用你自訂的移動程式，讓代理的父層角色節點朝該位置移動。

備註

導航系統不會自動移動 NavigationAgent 的父節點。移動完全由使用者自訂腳本控制。

NavigationAgent 內部會處理自身的路徑狀態與更新流程。

get_next_path_position() 函式會更新代理體多項內部狀態與屬性。此函式應於每次 _physics_process 只呼叫一次，直到 is_navigation_finished() 回報路徑已完成。若已抵達目標點或路徑終點，請勿再呼叫本函式，否則代理體會因持續更新路徑而在原地抖動。建議在腳本中儘早以 is_navigation_finished() 檢查路徑是否已結束。

以下距離屬性會影響路徑跟隨行為。

當代理體與下一個路徑點的距離小於 path_desired_distance 時，代理體會將內部路徑索引推進到下個路徑點。
當代理體與目標路徑點的距離小於 target_desired_distance 時，代理體會判定已抵達目標點並結束路徑。
當代理體偏離理想路徑到下一個路徑點的距離大於 path_max_distance 時，會重新請求尋路，因為代理體已經太遠離原路徑。

上述重要更新皆會於 _physics_process() 內呼叫 get_next_path_position() 時執行。

NavigationAgent 雖可搭配 process，但每次僅會於 _physics_process 進行一次更新。

下方將提供常與 NavigationAgent 搭配使用的各類節點之腳本範例。

路徑跟隨常見問題

編寫代理體移動腳本時，需注意下列常見問題與重要事項。

取得的路徑為空
如果在導航地圖尚未同步前（如於 _ready() 中）查詢路徑，可能會取得空路徑。這時 get_next_path_position() 會回傳與代理體父節點相同的位置，並視為已到達終點。解決方式為延遲呼叫，或等待導航地圖變更訊號後再查詢路徑。
代理體卡在兩個位置來回抖動
這通常是因為每幀都在重新計算路徑（例如最大路徑距離設定過短）所致。尋路會尋找離代理體最近且有效的導航網格位置，如果每一幀都重新尋路，第一個路徑點可能會在代理體當前位置前後不斷切換，導致角色來回抖動。
代理體有時會倒退回頭
若代理體速度過快，可能會直接超過 path_desired_distance 而無法推進路徑索引，導致代理體回頭走回上一個路徑點，直到通過距離判斷才往下個路徑點前進。請依代理體速度與更新頻率適當調整距離設定，並優化導航網格多邊形佈局（避免小範圍內擠太多邊）以改善此問題。
代理體有時會瞬間朝反方向旋轉
和上面代理體在兩點間抖動的情形一樣，這也多半是每幀過度更新路徑造成。根據導航網格佈局，尤其當代理體剛好位於網格邊緣或連接點時，路徑點有時可能會落在角色當下朝向的後方，此為精度誤差所致，不一定能完全避免。通常只有在角色瞬間朝向目前路徑點時才會明顯出現該現象。

NavigationAgent 迴避

本節介紹如何使用 NavigationAgent 的專屬導航迴避功能。

要讓 NavigationAgent 使用避障功能，必須將 avoidance_enabled 屬性設為 true。

../../_images/agent_avoidance_enabled.png

必須連接 NavigationAgent 節點的 velocity_computed 訊號，才能取得安全速度運算結果。

../../_images/agent_safevelocity_signal.png

請於 _physics_process() 內設定 NavigationAgent 節點的 velocity，以更新代理體的當前速度（通常為父節點的速度）。

當代理體啟用迴避後，每個物理更新時會收到 velocity_computed 訊號與 safe_velocity 向量。請使用此向量移動 NavigationAgent 的父節點，以避開其他代理體或迴避障礙物。

備註

只有同一張地圖上啟用迴避註冊的其他代理體，才會納入迴避運算考量。

備註

The NavigationAgent must be supplied with a target_position attribute, even if you are only using the agent for avoidance. Otherwise, the safe_velocity received from the velocity_computed signal will always be the zero vector.

下列 NavigationAgent 屬性與迴避有關：

height 屬性僅供 3D 使用。高度結合代理體目前全域 y 軸位置，決定代理體在迴避模擬中的垂直層級。使用 2D 迴避時，會自動忽略高於或低於自身的其他代理體或障礙。

radius 屬性設定代理體迴避圓的半徑（3D 為球體），代表代理體本身的碰撞體積，而非迴避動作的距離。

neighbor_distance 屬性設定代理體搜尋其他需迴避代理的半徑。數值越低，運算成本越小。

max_neighbors 屬性控制迴避運算時最多考慮多少個重疊半徑的代理體。設太低雖可減少運算，但可能導致部分代理體忽略迴避。

time_horizon_agents 及 time_horizon_obstacles 屬性設定預測其他代理體／障礙物的避障時間（秒）。代理體會選擇在此時間內不會碰撞的安全速度。預測時間建議盡量設低，否則代理體會提前減速以避免碰撞。

max_speed 屬性決定代理體避障運算時允許的最大速度。若父節點速度大於此值，safe_velocity 可能不足以避免碰撞。

use_3d_avoidance 屬性可切換代理體在下次更新時使用 2D（XZ 軸）或 3D（XYZ 軸）避障。2D 與 3D 避障彼此獨立，互不影響。

avoidance_layers 與 avoidance_mask 屬性為位元遮罩，類似物理層。代理體僅會避開與自身遮罩有交集的迴避層物件。

avoidance_priority 屬性讓高優先級代理體可忽略低優先級代理體。可用於讓特定代理體（如重要 NPC）在避障計算中獲得更高權重，而無需更動其整體遮罩或層級。

避障運算是在獨立空間進行，無法直接取得導航網格或物理碰撞資訊。實際上每個代理體在避障系統中是平面圓形（2D）或球體（3D）。若需考慮環境限制，可使用 NavigationObstacles，詳見使用 NavigationObstacle。

備註

避障功能不會影響路徑尋找。它適合用於那些無法（重新）烘焙到導航網格上的持續移動物件，以便讓代理體能繞行。

備註

RVO 避障法預設代理體會有自然的避讓行為，例如雙方相遇時會自動分流至左右。因此極端測試情境常會失敗，例如代理體完全正面對衝且速度相反，會因無法分配避讓方向而失效。

建議以 NavigationAgent 的 avoidance_enabled 屬性來切換避障。以下程式碼片段可用於切換代理的避障、建立或刪除避障回呼，或切換避障模式。
