碰撞体是不是触发器?
触发器不向传入 Rigidbody 注册碰撞,而是在刚体进入或退出触发器体积时发送 OnTriggerEnter、OnTriggerExit 和 OnTriggerStay 消息 。
using UnityEngine;
public class Example : MonoBehaviour { Collider m_ObjectCollider;
void Start() { //Fetch the GameObject's Collider (make sure they have a Collider component) m_ObjectCollider = GetComponent<Collider>(); //Here the GameObject's Collider is not a trigger m_ObjectCollider.isTrigger = false; //Output whether the Collider is a trigger type Collider or not Debug.Log("Trigger On : " + m_ObjectCollider.isTrigger); }
void OnMouseDown() { //GameObject's Collider is now a trigger Collider when the GameObject is clicked. It now acts as a trigger m_ObjectCollider.isTrigger = true; //Output to console the GameObject’s trigger state Debug.Log("Trigger On : " + m_ObjectCollider.isTrigger); } }
