UGUI优化技巧之Box Collider自适应大小
发表于2018-10-25
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,如何实现Collider自适应大小呢,下面就给大家分享一个简单的脚本,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 } } } } BoxColliderAdjust
