[游戏开发]Unity编辑器脚本每帧更新

Editor子类复写以下方法

public override bool RequiresConstantRepaint()
    {
        return true;
    }

eg:

using System.Globalization;
using UnityEditor;
using UnityEngine;
using UnityEngine.Video;

[CustomEditor(typeof(VideoPlayer))]
public class VideoPlayerEditor : Editor
{
    private VideoPlayer _videoPlayer;
    private float _curProcess;
    private string buttonStr;

    protected void OnEnable()
    {
        _videoPlayer = (VideoPlayer)target;
    }

    public override void OnInspectorGUI()
    {
        base.OnInspectorGUI();
        GUILayout.Space(5);

        GUILayout.Label(_curProcess.ToString(CultureInfo.InvariantCulture) + "s");
        _curProcess = GUILayout.HorizontalSlider(_curProcess, 0, (float)_videoPlayer.length);
        buttonStr = _videoPlayer.isPlaying ? "Pause" : "Play";
        _curProcess = (float)_videoPlayer.time;

        if (GUILayout.Button(buttonStr))
        {
            if (_videoPlayer.isPlaying)
            {
                _videoPlayer.Pause();
            }
            else
            {
                _videoPlayer.Play();
            }
        }
    }

    public override bool RequiresConstantRepaint()
    {
        return true;
    }
}
