【问题描述】：

我是使用 Unity 的新手，我正在尝试使用精灵作为碰撞触发器。 但我的 OnTriggerEnter2d 不会触发。 以下是信息：

主角信息

碰撞精灵用作触发信息

以及附在主角身上的 newPlatformRow 脚本的代码

using UnityEngine;
using System.Collections;

public class NewPlatformRow : MonoBehaviour 

    private float leftPlatformX = -12f; //de unde incepe platforma din stanga
    private float rightPlatformX = 3.123f; // de unde incepe platforma din dreapta
    private float rowDistance = -5f; //distanta dintre randurile de platforme

    private float leftPlatformWidth; //acestea vor fi calculate random pt fiecare rand nou
    private float rightPlatformWidth;





    // Use this for initialization
    void Start ()
    
        //Debug.Log("why wont you work ;_;");

    

    // Update is called once per frame
    void Update () 
        //Debug.Log("why wont you work ;_;");
    


    void OnTriggerEnter2d(Collider2D other)
    

        Debug.Log("why wont you work ;_;");

        if (other.gameObject.CompareTag("newPlatformRow"))
        

            Vector3 newLeftPlaformPosition;
            Vector3 newRightPlaformPosition;

            var leftPlatform = GameObject.Find("LeftWallPlatform");
            var rightPlatform = GameObject.Find("RightWallPlatform");

            newLeftPlaformPosition = new Vector3(leftPlatform.transform.position.x, leftPlatform.transform.position.y + rowDistance, leftPlatform.transform.position.z);
            newRightPlaformPosition = new Vector3(rightPlatform.transform.position.x, rightPlatform.transform.position.y + rowDistance, rightPlatform.transform.position.z);

            Transform leftPlatformTransform = leftPlatform.transform;
            Transform rightPlatformTransform = rightPlatform.transform;

            Transform newLeftPlatform = Instantiate(leftPlatformTransform, newLeftPlaformPosition, leftPlatformTransform.rotation) as Transform;
            Transform newRightPlatform = Instantiate(rightPlatformTransform, newLeftPlaformPosition, rightPlatformTransform.rotation) as Transform;

            newLeftPlatform.parent = leftPlatformTransform.parent;
            newRightPlatform.parent = rightPlatformTransform.parent;

        
    

不是那个：Debug.Log("why wont you work ;_;"); 它从未被调用过

完整的场景信息：

我真的不知道我做错了什么。 谢谢

【参考方案1】：

您似乎拼错了void OnTriggerEnter2d(Collider2D other)。 它实际上应该是OnTriggerEnter2D。注意这里的大写D。触发器和碰撞器的所有名称（如 OnMouseDown()）都以相同的方式工作 - 它们必须具有完全相同的名称，区分大小写。

【参考方案2】：

您没有选中材质组件中的 isTrigger 复选框。
