C# - 触发检测-OnTriggerEnter/Exit/Stay()

作用：检测触发OnTriggerEnter

例子：人物走过区域触发

代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class shoot : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
    }
    // Update is called once per frame
    void Update()
    {
    }
    private void OnTriggerEnter(Collider other){
        print("OnTriggerEnter:" + other);
        print("OnTriggerEnter:" + other.name);
        print("OnTriggerEnter:" + other.tag);
    }
    private void OnTriggerExit(Collider other){
        print("OnTriggerExit");
    }
    private void OnTriggerStay(Collider other){
        print("OnTriggerStay");
    }
}

代码的解释

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class shoot : MonoBehaviour
{
    // Start is called before the first frame update
    void Start()
    {
    }
    // Update is called once per frame
    void Update()
    {
    }
    private void OnTriggerEnter(Collider other){
        //碰到
        print("OnTriggerEnter:" + other);
        print("OnTriggerEnter:" + other.name);
        print("OnTriggerEnter:" + other.tag);
    }
    private void OnTriggerExit(Collider other){
        //离开
        print("OnTriggerExit");
    }
    private void OnTriggerStay(Collider other){
        //每一帧在这
        print("OnTriggerStay");
    }
}

用法：
1、注意文件命名，这里是shoot
2、区域的Box Collider 的Is Trigger 需要打勾，使可以进入内部
3、关掉Mesh Renderer 透明了
