小编Ben*_*umi的帖子

当我点击一个按钮时,它在On Click中调用方法ActivatePlayer:

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

public class LoadSceneOnClick : MonoBehaviour
{
    private Scene scene;

    private void Start()
    {
        scene = SceneManager.GetActiveScene();
        StartCoroutine(WaitForSceneUnLoad(SceneManager.GetSceneByName("The Space Station")));
    }

    public IEnumerator WaitForSceneUnLoad(Scene scene)
    {
        return null;
    }

    public void ActivatePlayer()
    {
        SceneManager.UnloadSceneAsync(0);
        Cursor.visible = false;
        GameControl.player.SetActive(true);
    }
}

但现在我想等待UnloadSceneAsync首先完成这一行:

SceneManager.UnloadSceneAsync(0);

只有当它完成卸载时,其余两行:

Cursor.visible = false;
GameControl.player.SetActive(true);

问题是,当我单击按钮时,我仍然会看到场景index0的第二个gui元素.索引中的场景是主菜单,当我单击按钮一秒钟时,我会看到主菜单文本的一部分.在卸载主菜单之前,它似乎正在激活播放器.由于主菜单和播放器都有摄像头的场景,我看到主菜单一秒钟.

设置新材质后，我想更改并设置3件事：

首先将着色器类型更改为“不亮/彩色”

Second反照率颜色，例如将其更改为：255,0,0,255

第三金属值从0到1

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

public class DoorsLockManager : MonoBehaviour
{
    public bool locked;
    public Color lockedColor = Color.red;
    public Color unlockedColor = Color.green;
    public Renderer rend;

    private GameObject[] doorPlanes;

    private void Start()
    {
        doorPlanes = GameObject.FindGameObjectsWithTag("DoorPlane");

        for (int i = 0; i < doorPlanes.Length; i++)
        {
            rend = doorPlanes[i].GetComponent<Renderer>();
            if (locked)
            {
                rend.material.SetFloat("Metallic", 1);
                rend.material.color = lockedColor;
            }
            else
            {
                rend.material.color = unlockedColor;
            }
        }
    }

    // Update is called once per frame
    void …

我没等,但我猜测同样的问题是分钟.当计时器倒计时并且秒数变为1时,它会变为59而不是先播种0.我不确定计时器的逻辑,如果在向上/向下计数时它应该显示0.

当它正在计算它的工作正常时,它在59之后显示为0.

private void timer1_Tick(object sender, EventArgs e)
        {
            if (countUpCheckbox.Checked)
            {
                Invoke(new Action(() =>
                {
                    seconds += 1;

                    if (seconds == 60)
                    {
                        seconds = 0;
                        minutes += 1;
                    }

                    if (minutes == 60)
                    {
                        minutes = 0;
                        hours += 1;
                    }

                    richTextBox1.Text = string.Format("{0}:{1}:{2}", hours.ToString().PadLeft(2, '0'), minutes.ToString().PadLeft(2, '0'), seconds.ToString().PadLeft(2, '0'));
                }));
            }

            if (countdownCheckbox.Checked)
            {
                Invoke(new Action(() =>
                {
                    seconds -= 1;

                    if (seconds == 0)
                    {
                        seconds = 59;
                        minutes -= 1;
                    }

                    if (minutes == 0) …

作为参考，此代码来自对这个问题的回答：

突出显示颜色与 RichTextBox 文本中所有其他选择不同的单词或短语？

using System.Collections.Generic;
using System.Drawing;
using System.Text.RegularExpressions;
using System.Windows.Forms;

private class TextSearcher
{
    private BindingSource m_bsMatches = null;
    private RichTextBox m_Rtb = null;

    public TextSearcher(RichTextBox rtb) : this(rtb, Color.Yellow, Color.Red) { }
    public TextSearcher(RichTextBox rtb, Color selectionColor, Color currentColor)
    {
        this.m_Rtb = rtb;
        SelectionColor = selectionColor;
        CurrentColor = currentColor;
    }

    public string CurrentKeywords { get; private set; } = string.Empty;
    public bool CaseSensitive { get; set; } = true;
    public int CurrentIndex => m_bsMatches.Position;
    public Match CurrentMatch …

selected.GetComponent()

selected是一个GameObject,我想找到它是否有任何组件,而不仅仅是特定的组件或类型.
