<description>
2D Agent that is used in navigation to reach a location while avoiding static and dynamic obstacles. The dynamic obstacles are avoided using RVO collision avoidance. The agent needs navigation data to work correctly. [NavigationAgent2D] is physics safe.
[b]Note:[/b] After [method set_target_location] is used it is required to use the [method get_next_location] function once every physics frame to update the internal path logic of the NavigationAgent. The returned vector position from this function should be used as the next movement position for the agent's parent Node.
