unity3d-游戏实战突出重围，第二天 制作血条

 using UnityEngine;
 using System.Collections;

 public class xt : MonoBehaviour
 {

     //红色血条
     public Texture2D blood_red;
     //黑色血条
     public Texture2D blood_black;
     //当前生命值
     private int HP = ;

     void OnGUI()
     {
         if (GUILayout.RepeatButton("加血"))
         {
             //增加生命值
             if (HP < )
             {
                 HP++;
             }
         }
         if (GUILayout.RepeatButton("减血"))
         {
             //减少生命值
             if (HP > )
             {
                 HP--;
             }
         }
         //根据当前生命值计算红色血条显示的宽度
         int blood_width = blood_red.width * HP / ;
         //绘制黑色血条
         GUI.DrawTexture(new Rect(, , blood_black.width, blood_black.height), blood_black);
         //绘制红色血条
         GUI.DrawTexture(new Rect(, , blood_width, blood_red.height), blood_red);

     }
 }
