获取代理在世界坐标系单位中的目标或尝试设置代理在其中的目标。
获取：
返回此代理的目标集。
• If a destination is set but the path is not yet processed the position returned will be valid navmesh position that's closest to the previously set position.
• If the agent has no path or requested path - returns the agents position on the navmesh.
• If the agent is not mapped to the navmesh (e.g. Scene has no navmesh) - returns a position at infinity.
设置：
请求代理移至最接近所请求的目标的有效导航网格位置。
• The path result may not become available until after a few frames. Use pathPending to query for outstanding results.
• If it's not possible to find a valid nearby navmesh position (e.g. Scene has no navmesh) no path is requested. Use SetDestination and check return value if you need to handle this case explicitly.
