点 point
是否在包围盒内?
如果传递给 Contains 的点 point
在包围盒内,则返回 True 值。包围盒的最小值和最大值限制(角和边)上的点被视为在内部。
注意: 如果 Bounds.extents 在任何坐标中包含负值,则 Bounds.Contains 将始终返回 False。
//Attach this script to a GameObject with a Collider component //Create an empty GameObject (Create>Create Empty) and attach it in the New Transform field in the Inspector of the first GameObject //This script tells if a point you specify (the position of the empty GameObject) is within the first GameObject’s Collider
using UnityEngine;
public class Example : MonoBehaviour { //Make sure to assign this in the Inspector window public Transform m_NewTransform; Collider m_Collider; Vector3 m_Point;
void Start() { //Fetch the Collider from the GameObject this script is attached to m_Collider = GetComponent<Collider>(); //Assign the point to be that of the Transform you assign in the Inspector window m_Point = m_NewTransform.position; }
void Update() { //If the first GameObject's Bounds contains the Transform's position, output a message in the console if (m_Collider.bounds.Contains(m_Point)) { Debug.Log("Bounds contain the point : " + m_Point); } } }
