[Unity3D]使用碰撞体触发器实现自动开门

1.先手动操作animation开门和关门动画，生成自动门的移动动画

2.新建脚本Door.cs负载在门Door上。
在Door上新建组件animation

public class Door : MonoBehaviour
{
    //  private Transform door_transform;
    private Animation animation;
    // Start is called before the first frame update
    void Start()
    {
        // door_transform = gameObject.GetComponent();
        animation = gameObject.GetComponent();
     //   animation["OpenDoorAni"].time = animation["OpenDoorAni"].clip.length;
   
    }

    void OnTriggerEnter(Collider coll)
    {
        if (coll.gameObject.name == "Student")
        {
            animation.Play("OpenDoorAni");
        }
    }
    void OnTriggerExit(Collider coll)
    {
        if (coll.gameObject.name == "Student")
        {
            animation.Play("CloseDoorAni");
        }
    }
}
