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 = 100;

    void OnGUI()
    {
        if (GUILayout.RepeatButton("加血"))
        {
            //增加生命值
            if (HP < 100)
            {
                HP++;
            }
        }
        if (GUILayout.RepeatButton("减血"))
        {
            //减少生命值
            if (HP > 0)
            {
                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 / 100;
        //绘制黑色血条
        GUI.DrawTexture(new Rect(100, 100, blood_black.width, blood_black.height), blood_black);
        //绘制红色血条
        GUI.DrawTexture(new Rect(100, 100, blood_width, blood_red.height), blood_red);

    }
}
