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(, , );//月球自传

        transform.Rotate(, , );//地球自转

        sun.transform.Rotate(Vector3.up);//太阳自转

        moon.transform.RotateAround(transform.position, Vector3.up, );//月亮围绕地球转

        transform.RotateAround(sun.transform.position, Vector3.up, );//地球围绕太阳转

    }

}

3.UI之游戏界面

登录错误提示：

提示登录失败用：

if (this.gameObject.activeSelf)
{
time += Time.deltaTime;//计时器
if (time > 3)
{
failText.gameObject.SetActive(false);//登录失败消失
time = 0;
}
}

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 UnityEngine;

using UnityEngine.SceneManagement;

using UnityEngine.UI;

public class UIcontrol : MonoBehaviour {

    public InputField InputUserName;

    public InputField InputPassWord;

    public Button button;

    public GameObject failText;

    public Button closeSetting;

    public GameObject Panel;

    public Slider slider;

    public Toggle toggle;

    AudioSource audio;

    // Use this for initialization

    void Start () {

        InputUserName = InputUserName.GetComponent<InputField>();

        InputPassWord = InputPassWord.GetComponent<InputField>();

        button = button.GetComponent<Button>();

        closeSetting = closeSetting.GetComponent<Button>();

        slider = slider.GetComponent<Slider>();

        audio = GetComponent<AudioSource>();

        slider.maxValue = ;

        slider.minValue = ;

        slider.value = ;

    }

    public void GetButton()

    {

        if (InputUserName.text == "huangwei" && InputPassWord.text == "")

        {

            SceneManager.LoadScene();

        }

        else

        {

            failText.gameObject.SetActive(true);//登录失败出现

        }

    }

    public void OpenSetting()

    {

        Panel.gameObject.SetActive(true);//打开设置

    }

    public void CloseSetting()//关闭设置

    {

        Panel.gameObject.SetActive(false);

    }

    // Update is called once per frame

    float time;

    void Update()

    {

        if (this.gameObject.activeSelf)

        {

            time += Time.deltaTime;//计时器

            if (time > )

            {

                failText.gameObject.SetActive(false);//登录失败消失

                time = ;

            }

        }

        if (toggle.isOn==true)

        {

            audio.mute = true;//静音

        }

        else

        {

            audio.mute = false;

        }

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

    }

}

4.进度条slider:

using System.Collections;

using System.Collections.Generic;

using UnityEngine;

using UnityEngine.UI;

public class test : MonoBehaviour {

    Text test01;

    int num = ;

    float time;

    public Slider slider;

    // Use this for initialization

    void Start () {

        test01 = this.GetComponent<Text>();

        slider = slider.GetComponent<Slider>();

        slider.maxValue = ;

        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 > )

        {

            time = ;

        }

        slider.value = time * ;

            test01.text = (int)(time*)+ "  %";

    }

}

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 = ;//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 <= )//技能控制在5秒冷却

            {

                f = ( - time);//5秒倒计时

                image.fillAmount = (f) / ;//image也在360度递减

                text.text = (f).ToString();//文本输出倒计时

                if (f < 0.1f && f >= )/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 = ;//超过5秒后时间置零

                b = false;/tton点击后又可以计时了

            }

        }

    }

}
