unity3d 延迟执行脚本语句  在Unity3D中，有yield语句它负责延迟操作，yield return WaitForSeconds(3.0); //等待 3 秒

查看unity3d脚本手册，用法需要在相应的格式。

下面代码含义就是，加载图片显示等待6秒后进入场景level1中。

using UnityEngine;
        using System.Collections;
       
        public class init : MonoBehaviour {
       
                // Use this for initialization
                public Texture img;
                private bool bl = false;
                public float waitTime ;
                void Start () {
                 StartCoroutine( wait(6.0f) );
       
                }
               
                // Update is called once per frame
                void Update () {
                 if (bl)
                 Application.LoadLevel(1);
       
                }
       
                void OnGUI()
                {
                 GUI.DrawTexture(new Rect(0,0,1024,768),img);
                }
       
                IEnumerator wait(float time)
                {
                 yield return new WaitForSeconds(waitTime);
                 bl = true;
                }
        }
