Unity3d — — UGUI之Box Collider自适应大小

NGUI下给Sprite/image添加collider后能自适应大小，但是在UGUI下Collider是默认在（0，0）位置，size为0

因此写了个简单的脚本，效果如下（最后附代码）

1.如下图添加Box Collider 2D后的默认位置与大小

 

2.给需要的物体添加Script并运行后的效果：

 

 

代码：

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

public class BoxColliderAdjust : MonoBehaviour {

    public bool AdjustBoxCollider = false;
    private BoxCollider2D boxCollider2D;
    private RectTransform gameObject;
    // Use this for initialization
     void Start () {
        gameObject = this.GetComponent<RectTransform>();
        boxCollider2D = this.GetComponent<BoxCollider2D>();
    }
    
    // Update is called once per frame
    void Update () {
        if (boxCollider2D == null)
        {
            Debug.Log("can't find collider");
            return;
        }
        else
        {

            if (AdjustBoxCollider == true)
            {
                boxCollider2D.offset = gameObject.rect.center;      //把box collider设置到物体的中心
                boxCollider2D.size = new Vector2(gameObject.rect.width, gameObject.rect.height);    //改变collider大小
            }
        }
    }
}
