c# - OnCollisionEnter 不工作 Unity3D

Question

我正在尝试构建一个游戏，您需要在其中躲避掉落的物体。我已经制造了危险，但似乎危险“克隆”的行为有所不同。

我已经制作了一个碰撞脚本，当危险撞击到它需要消失的平台时。这适用于危险对象，但不适用于掉落的危险克隆对象。

• 正如您在第一个屏幕截图中看到的，红色圆圈 block 的行为喜欢它使用。但是蓝色圆圈一次(克隆)直接穿过对象。
• 正如你在第二张截图中看到的，红色圆圈消失了，因为它撞到了平台。但还是蓝色一旦落下就对了通过。

提前致谢!

下面是碰撞脚本，下面是危险生成脚本:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 public class HazardCollisionFunctions : MonoBehaviour {

 #region Variables
 //Public

 //Private
 #endregion

 #region UnityFunctions
 void Start()
 {

 }
 void Update()
 {

 }
 #endregion

 private void OnCollisionEnter(Collision collision)
 {
     if(collision.gameObject.tag == "platform")
     {
         this.gameObject.SetActive(false);
     }

     if(collision.gameObject.tag == "Player")
     {

     }
 }
 }

OnCollisionEnter

OnCollisionEnter需要 Collision对象作为参数，它要求附加的 Collider 组件的 isTrigger 属性为 FALSE。

void OnCollisionEnter(Collision collision)
{
    foreach (ContactPoint contact in collision.contacts)
    {
        Debug.DrawRay(contact.point, contact.normal, Color.white);
    }
}

触发输入

OnTriggerEnter需要 Collider对象作为参数，它要求附加的 Collider 组件的 isTrigger 属性为 TRUE。

void OnTriggerEnter(Collider other)
{
    if (other.CompareTag("CheckPoint"))
    {
        Destroy(other.gameObject);
    }
}

1. If you are instantiating the object from prefab, make sure that prefab have required components (rigidbody/collider) and properties to achieve the desired behaviour.

2. To detect Collision/Trigger, at least one of the object must have a physics component (Rigidbody)

3. Rigidbody MUST be attached to the moving object.
