unity之UI

1.Vector3坐标

2.地球，月球，太阳的旋转关系

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class spere01 : MonoBehaviour {
    public GameObject moon;
    public GameObject sun;
    // Use this for initialization
    void Start () {

    }

    // Update is called once per frame
    void Update () {
        // transform.Rotate(Vector3.up, 2, Space.World);//up表示围绕上面轴旋转
        moon.transform.Rotate(0, 1, 0);//月球自传
        transform.Rotate(0, 1, 0);//地球自转
        sun.transform.Rotate(Vector3.up);//太阳自转
        moon.transform.RotateAround(transform.position, Vector3.up, 1);//月亮围绕地球转
        transform.RotateAround(sun.transform.position, Vector3.up, 1);//地球围绕太阳转

    }
}

using System.Collections;

using UnityEngine.UI;

public class test : MonoBehaviour {

    Text test01;
    float time = 0;
    public Image image;
    float sum = 100;
    bool b = false;
    // Use this for initialization
    void Start () {

    }

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

    }

进入游戏就有声音：

 slider.maxValue = 100;
        slider.minValue = 0;
        slider.value = 50;//赋初值

  if (toggle.isOn==true)
        {

            audio.mute = true;//静音
        }
        else
        {
            audio.mute = false;
        }

        audio.volume =(float) (slider.value/100);//把音量条的值赋给背景音乐

//总代码
using System.Collections;
using System.Collections.Generic;

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

public class test : MonoBehaviour {

    Text test01;
    int num = 0;
    float time;

    public Slider slider;
    // Use this for initialization
    void Start () {
        test01 = this.GetComponent<Text>();
        slider = slider.GetComponent<Slider>();
        slider.maxValue = 100;
        slider.value = slider.minValue;
    }

    // Update is called once per frame
    void Update () {
        time += Time.deltaTime;
        //if (time >0.1f)
        //{
        //    num++;
        //    if (num >100)
        //    {
        //        num = 100;
        //        test01.text = num + "  %";
        //    }
        //    else
        //    {
        //        slider.value = num;
        //        time = 0;
        //    }

        //}
        //test01.text = num + "  %";
        //另一种方法

        if (time > 10)
        {
            time = 10;
        }
        slider.value = time * 10;
            test01.text = (int)(time*10)+ "  %";
    }
}

技能冷却：
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class CoolSkill : MonoBehaviour
{
    public Image image;
    float time;
    float f;
    public Text text;
    bool b = false;
    bool bb = true;
    // Use this for initialization
    void Start()
    {
        image = image.GetComponent<Image>();
        text = text.GetComponent<Text>();
        image.fillAmount = 0;//默认可以发出技能
    }
    public void GetBool()
    {
        if (bb)//限制技能开启后才能使用
        {
            b = true;
            bb = false;
        }
    }
    // Update is called once per frame
    void Update()
    {
        if (b)
        {
            time += Time.deltaTime;
            if (time <= 5)//技能控制在5秒冷却
            {
                f = (5 - time);//5秒倒计时
                image.fillAmount = (f) / 5;//image也在360度递减
                text.text = (f).ToString();//文本输出倒计时
                if (f < 0.1f && f >= 0)/控制在0.1秒以内结束时才可以重新开启技能
                {
                    bb = true;//重新开启技能Button可以点击了
                }
            }
            else
            {
                time = 0;//超过5秒后时间置零
                b = false;/tton点击后又可以计时了
            }

        }

    }
