小编Dan*_*Lip的帖子

这就是我声明列表的方式：

using System;
using System.Collections;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using UnityEditor;
using UnityEngine;
using UnityEditorInternal;

public class ConversationTrigger : MonoBehaviour
{
    public List<Conversation> conversations = new List<Conversation>();

这是使用此 List 的编辑器脚本：

using System.Collections;
using System.Collections.Generic;
using UnityEditor;
using UnityEditorInternal;
using UnityEngine;

[CustomEditor(typeof(ConversationTrigger))]
public class ConversationTriggerEditor : Editor
{
    private ReorderableList ConversationsList;

    private void OnEnable()
    {
        ConversationTrigger conversationtrigger = (ConversationTrigger)target;
        ConversationsList = new ReorderableList(serializedObject, serializedObject.FindProperty("conversations"), true, true, true, true); 
    }

    public override void OnInspectorGUI()
    {
        serializedObject.Update();
        ConversationsList.DoLayoutList();
        serializedObject.ApplyModifiedProperties();
        EditorUtility.SetDirty(target);
    } …

Transform[] drawns = GetComponentsInChildren<Transform>()

这还包括父级，但我只想获取脚本所连接的转换的子级。

问题是它在循环中也破坏了父级。绘制数组中的第一项是父项：

case DrawStates.DrawOnGizmosRuntime:
drawOnce = true;
if (line != null && drawOnGizmos == false)
{
    Transform[] drawns = GetComponentsInChildren<Transform>();
    if (drawns.Length > 0)
    {
        foreach (Transform drawn in drawns)
        {
            Destroy(drawn.gameObject);
        }
    }
}
if (boxCollider == null)
{
    boxCollider = boxColliderToDrawOn.GetComponent<BoxCollider>();
}
drawOnGizmos = true;
break;

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;

namespace Test
{
    public partial class Form1 : Form
    {
        int x1, x2, wid = 100;

        public Form1()
        {
            InitializeComponent();

            x1 = this.Width / 2 ;
            x2 = this.Height / 2 ;
        }

        private void Form1_Load(object sender, EventArgs e)
        {

        }

        private void Form1_Paint(object sender, PaintEventArgs e)
        {


            e.Graphics.DrawEllipse(Pens.Red, x1,x2, wid, wid);
        }
    }
}

我想在表单中间绘制一个简单的圆，然后再绘制从圆心出来的线。我该怎么做 ？

private void OnGUI()
    {
        GUIStyle myStyle = new GUIStyle();
        myStyle.fontSize = 20;

        GUILayout.BeginVertical(GUI.skin.box);
        GUILayout.Label("Replacing");
        GUI.Label(new Rect(650, 650, 300, 50), "HELLO WORLD", myStyle);
    }

我看到“替换”标签，但字体很小。所以我想测试使用 new Rect 更改大小，但我在任何地方都看不到 HELLO WORLD。

问题是它很短。动画是走路。但是动画长度很短，我想延长行走的时间。

当我选择行走动画时，我看到它是只读的：

选择它后，我可以更改时间，但剪辑本身仍然很短：

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

[ExecuteAlways]
public class SkyBox : MonoBehaviour
{
    public Material[] skyboxes;
    public Camera skyboxCamera;
    public float skyboxMoveSpeed = 2f;

    private int index = 0;

    // Start is called before the first frame update
    void Start()
    {

    }

    // Update is called once per frame
    void Update()
    {
        if (Input.GetKeyDown(KeyCode.Escape))
        {
            SwitchSkybox();
        }

        if (RenderSettings.skybox == skyboxes[1])
        {
            RenderSettings.skybox.SetFloat("_Rotation", Time.time * skyboxMoveSpeed);
        }
    }

    public void SwitchSkybox()
    {
        index++;
        if (index == skyboxes.Length)
        {
            index = …

目标是控制 BackGroundWorkerDoWork事件中的帧提取速度。

我尝试过Thread.Sleep()，但它抛出异常。

这就是我想做的。上面和底部都有描述。

            vFReader.Open(@"C:\Users\Chocolade 1972\Downloads\MyVid.mp4");
            trackBar1.Maximum = (int)vFReader.FrameCount;
        }
    }

    private void button1_Click(object sender, EventArgs e)
    {
        backgroundWorker1.RunWorkerAsync();
    }

我创建了一个名为的新类SiteDownload，并添加了一些下载图像的链接：

using System.Collections.Generic;
using System.Linq;
using System.Net;
using System.Threading.Tasks;

    public class SiteDownload
    {
        public static List<string> Sites()
        {
            List<string> list = new List<string>();

            list.Add("mysite.com/sites/default/files/1231105.gif");
            list.Add("mysite.com/sites/default/files/1231040.gif");

        return list;
        }

        public static async Task<List<Website>> ParallelDownload(IProgress<ProgressReport> progress, CancellationTokenSource cancellationTokenSource)
        {
            List<string> sites = Sites();
            List<Website> list = new List<Website>();
            ProgressReport progressReport = new ProgressReport();
            ParallelOptions parallelOptions = new ParallelOptions();
            parallelOptions.MaxDegreeOfParallelism = 8;
            parallelOptions.CancellationToken = cancellationTokenSource.Token;
            await Task.Run(() =>
            {
                try
                {
                    Parallel.ForEach<string>(sites, parallelOptions, (site) =>
                    {
                        Website results = Download(site);
                        list.Add(results); …

我正在使用的命令：

ffmpeg -f gdigrab -framerate 24 -i desktop -preset ultrafast -pix_fmt yuv420p camera1.mp4

Stream #0：没有足够的帧来估计速率；考虑增加探针尺寸

并且 ：

不推荐使用 AVStream.codec 将编解码器参数传递给多路复用器，请改用 AVStream.codecpar。

然后一直：

过去的持续时间 0.810524 太大

我的 gif 动画大小为 2.5MB，是从 mp4 视频转换而来的。
