支援不同角色移動方式

若要支援不同的角色移動方式（如蹲下或爬行），必須用類似於支援不同角色型別的地圖配置方式。

針對蹲下或爬行的角色，烘焙高度適合的導覽網格，讓角色能夠在遊戲世界中的狹窄區域順利尋路。

當角色改變移動狀態（例如站起來、開始蹲下或爬行）時，應查詢對應地圖以取得路徑。

如果避障行為也需要隨移動方式改變（例如只在站立時啟用避障，或只避開相同行動狀態的其他代理），每當角色切換移動狀態時，也應將其避障代理切換到對應的避障地圖。

func update_path():

    if actor_standing:
        path = NavigationServer3D.map_get_path(standing_navigation_map_rid, start_position, target_position, true)
    elif actor_crouching:
        path = NavigationServer3D.map_get_path(crouched_navigation_map_rid, start_position, target_position, true)
    elif actor_crawling:
        path = NavigationServer3D.map_get_path(crawling_navigation_map_rid, start_position, target_position, true)

func change_agent_avoidance_state():

    if actor_standing:
        NavigationServer3D.agent_set_map(avoidance_agent_rid, standing_navigation_map_rid)
    elif actor_crouching:
        NavigationServer3D.agent_set_map(avoidance_agent_rid, crouched_navigation_map_rid)
    elif actor_crawling:
        NavigationServer3D.agent_set_map(avoidance_agent_rid, crawling_navigation_map_rid)

private void UpdatePath()
{
    if (_actorStanding)
    {
        _path = NavigationServer3D.MapGetPath(_standingNavigationMapRid, _startPosition, _targetPosition, true);
    }
    else if (_actorCrouching)
    {
        _path = NavigationServer3D.MapGetPath(_crouchedNavigationMapRid, _startPosition, _targetPosition, true);
    }
    else if (_actorCrawling)
    {
        _path = NavigationServer3D.MapGetPath(_crawlingNavigationMapRid, _startPosition, _targetPosition, true);
    }
}

private void ChangeAgentAvoidanceState()
{
    if (_actorStanding)
    {
        NavigationServer3D.AgentSetMap(_avoidanceAgentRid, _standingNavigationMapRid);
    }
    else if (_actorCrouching)
    {
        NavigationServer3D.AgentSetMap(_avoidanceAgentRid, _crouchedNavigationMapRid);
    }
    else if (_actorCrawling)
    {
        NavigationServer3D.AgentSetMap(_avoidanceAgentRid, _crawlingNavigationMapRid);
    }
}

備註

雖然可以對多個地圖立即進行路徑查詢，但切換避障代理所使用的地圖僅會在下次伺服器同步後生效。
