重點是yield和StartCoroutine的使用

using UnityEngine;using System.Collections;public class MainBoardTop : MonoBehaviour{        public Texture2D Logo;        public Texture2D SysInfo;        public Texture2D FriInfo;        public Texture2D IcoHelp;        public GUIStyle style;        public GUIStyle pathStyle;        private bool displaySysLabel = false;        private bool displayFriLabel = false;        IEnumerator Start()        {                yield return StartCoroutine(flashSysLabel());                yield return StartCoroutine(flashFriLabel());        }        IEnumerator flashSysLabel()        {                while(true)                {                        displaySysLabel = true;                        yield return new WaitForSeconds(0.5f);                        displaySysLabel = false;                        yield return new WaitForSeconds(0.5f);                }        }        IEnumerator flashFriLabel()        {                while(true)                {                        displayFriLabel = true;                        yield return new WaitForSeconds(0.5f);                        displayFriLabel = false;                        yield return new WaitForSeconds(0.5f);                }        }        void OnGUI()        {                GUI.BeginGroup(new Rect(0, 0, 300, 100));                GUI.Button(new Rect(3,5,37,37),Logo,style);                GUI.Button(new Rect(45,8,150,15),"test",pathStyle);                if(displaySysLabel == true)                {                        GUI.Label(new Rect(45,25,16,16),SysInfo,style);                }                GUI.Label(new Rect(61,25,16,16),"0",style);                if(displayFriLabel == true)                {                        GUI.Label(new Rect(77,25,16,16),FriInfo,style);                }                GUI.Label(new Rect(93,25,16,16),"0",style);                GUI.Label(new Rect(108,25,16,16),IcoHelp,style);                GUI.EndGroup();        }}
