Question

我创建了一个UI滑块，它根据我的脚本中的值（播放时间）移动，到目前为止它运行顺畅。这是我的滑块代码

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

public class testingtime : MonoBehaviour {

    public int playtime =0;
    public int seconds = 0;
    private int minutes = 0;
    private int hours = 0;
    public int playtimemax = 0;

    public Slider testslider;
    public Texture playbutton;
    public Texture Pausebutton;

     Texture substitute;
    bool ispaused = false;
    // Use this for initialization
    void Start () {
        substitute = Pausebutton;
        StartCoroutine ("playtimer");
    }

    private IEnumerator playtimer(){
        while (true) {
            yield return new WaitForSeconds(1);
            playtime += 1;
            seconds = (playtime % 60);
            minutes = (playtime / 60) % 60;
            hours = (playtime / 3600) % 24;

                }
        }



    // Update is called once per frame
    void Update () {
        testslider.value = playtime;

        if (ispaused) {
            Time.timeScale = 0;
            substitute = playbutton;
                }
        if (!ispaused) {
            Time.timeScale = 1;
            substitute = Pausebutton;
                }
        playtime = (int)testslider.value;

    }
    void  OnGUI (){
    if (GUI.Button (new Rect (685,710, 20, 20), substitute)) {
            ispaused = !ispaused;
        }

        GUI.Label (new Rect (50, 50, 400, 50), "Playtime = " + hours.ToString () + " Hours " + minutes.ToString () + " Minutes " + seconds.ToString () + " Seconds");

        }
}

所以基本上这会让我的滑块根据游戏时间移动，每秒钟像计时器一样增加1。但是我尝试通过滑块（我已启用交互式）将代码playtime = (int)testslider.value;更改为playtime的值。我知道我无法移动滑块，因为它不断更新testtimer.value = playtime。是否有任何可用的功能，例如testtimer.onclicked，以便我可以将它放在if函数中并禁用更新？

Answer 1

Slider具有onValueChanged回调功能，您可以将其用于此目的。

我知道了！：D最后您只需要这段代码

public void adjusttimer(float newtime){
        playtime = (int)newtime;
        }

并指定类似 enter image description here

的方法

它应该完美地工作。：d 非常感谢Max Yankov的想法！
