Question

我正在使用这个脚本来创建一个npc角色，它将在randm的游戏区域周围运行以设置游戏点数，并且我已经在我的游戏中创建了一个，但是当我尝试使用脚本来创建它时npc在List _patrolPoints中丢失所有方向点，它只会创建坐在那里的多维数据集，因为没有任何方式点而不会移动

您用于NPC属性的对象是预制件吗？如果是这样，它应该保留您在编辑器中为该预制件设置的所有值。

但是，如果您的_patrolpoints不是预制件的一部分（即。NPC是您在编辑器中配置的场景内对象），那么您需要申请那些_patrolpoints手动为每个实例化的副本。

您的代码没有显示_patrolpoints的设置位置，但对于下面的代码段，我们假设_patrolpoints是导航网格的公共数组字段（而不是私人名单），

void Update() 
{
    if (SpawnFire < 20 && Time.time > SpawnFire) {
        SpawnFire = Time.time + SpawnRate;
        GameObject copy = Instantiate(NPC, NPCspawn1.position, NPCspawn1.rotation);
        navmesh nm = copy.GetComponent<navmesh>();
        nm._patrolpoints = master_array_of_patrol_points;
    }
}

使用其他脚本实例化对象
