using UnityEngine;
using System.Collections;
using UnityEngine.UI;

public class HealthController : MonoBehaviour {

    //当前对象是血条还是蓝条
    public bool isHealth = false;
    //虚拟轴,横轴,纵轴
    private float hor,ver;
    //血条的最大宽度
    private float healthMaxWidth = 470;
    //蓝条的最大宽度
    private float powerMaxWidth = 425;
    //当前的虚拟轴
    private float currentAxis;
    //当前的最大宽度
    private float currentMaxWidth;
    //RectTransform组件
    private RectTransform rectTr;
    //速度
    public float speed = 100;
    //血条文本
    public Text healthText;
    //蓝条文本
    public Text powerText;
    //血条蓝条的最大值
    public float healthMaxValue = 1000f;
    public float powerMaxValue = 500f;
    //当前的条的最大值
    private float currentMaxValue;
    //当前修改的文本显示框
    private Text currentText;

    void Start()
    {
        rectTr = GetComponent<RectTransform> ();
    }

    void Update()
    {
        hor = Input.GetAxis ("Horizontal");
        ver = Input.GetAxis ("Vertical");
        //如果是血条
        if (isHealth) {
            currentAxis = hor;
            currentMaxWidth = healthMaxWidth;
            currentText = healthText;
            currentMaxValue = healthMaxValue;
        }
        //如果是蓝条
        else {
            currentAxis = ver;
            currentMaxWidth = powerMaxWidth;
            currentText = powerText;
            currentMaxValue = powerMaxValue;
        }
        //根据用户的操作,计算当前条的宽度
        float newWidth = rectTr.sizeDelta.x +
            currentAxis * Time.deltaTime * speed;
        //限制宽度
        float realWidth = Mathf.Clamp (newWidth, 0, currentMaxWidth);
        //赋值到RectTransform
        rectTr.sizeDelta = new Vector2(realWidth,rectTr.sizeDelta.y);
        //计算当前数值
        float currentValue = (realWidth / currentMaxWidth) * currentMaxValue;
        //转整数操作
        currentValue = Mathf.Round (currentValue);
        //将数值信息显示到Text
        currentText.text = currentValue.ToString () + "/"
            + currentMaxValue.ToString ();
    }
}

血条,蓝条对象上都挂上此脚本
