unity3d简单血条的制作方法

通过gui的GUI.DrawTexture方法来实现血条，如下图：

 

 using UnityEngine;
 using System.Collections;

 ///
 /// 血条
 /// 小伍 QQ:16349023

 public class Wy2HealthBar : MonoBehaviour {

     public Texture2D HealthBg;
     public Texture2D Heathforce;

     public Vector2 offset = new Vector2(13,15);

     private Wy2AIHealth health;



     void Setup()
     {
         health = GetComponent();
     }

     void Reset()
     {
         Setup();
     }

     // Use this for initialization
     void Start () {
         Setup();
     }

     // Update is called once per frame
     void Update () {

     }

     void OnGUI()
     {
         if (Event.current.type != EventType.Repaint)
         {
             return;
         }
         Rect rectbg=new Rect(0,0,256,64);

         GUI.DrawTexture(rectbg, HealthBg);

         float width = (health.CurrentHealth*145) / health.MaxHealth;

         if (width < 1) return;

         Rect rectfc = new Rect(offset.x, offset.y, width, 10);
         GUI.DrawTexture(rectfc, Heathforce);
     }
 }

 

其中health是角色的生命脚本对象，maxhealth-最大血量，currenthealth是当前血量
