NGUI实现UITexture的UV滚动

材质上使用的贴图:

效果:实现该纹理在屏幕上的滚动

代码:

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

 public class NewBehaviourScript : MonoBehaviour
 {
     [SerializeField]
     float USpeed;
     [SerializeField]
     float VSpeed;

     UITexture tex;

     void Start()
     {
         if (null == tex)
             tex = gameObject.GetComponent<UITexture>();
     }

     void Update()
     {
         float newOffsetU = USpeed * Time.time;
         float newOffsetV = VSpeed * Time.time;

         if (null != tex)
         {
             tex.enabled = false;
             tex.material.mainTextureOffset = new Vector2(newOffsetU, newOffsetV);
             tex.enabled = true;
         }
     }
 }

需要注意:纹理的寻址模式应该设置为 重复寻址模式（Repeat）
