19年左右调研Timeline的相关文档

PlayDirector

通过TimelineEditor可以获取当前主运行Timeline的PlayDirector的句柄。

可以实现运行时针对此Timeline的播放，结束，暂停，恢复，前后帧移动，刷新等功能

RefreshGUI刷新Timeline的编辑器窗口

代码如下

using System.Reflection;
using UnityEditor;
using UnityEditor.Timeline;
using UnityEngine;public class TimelineControl : EditorWindow
{[MenuItem("Tools/TimelineControl")]private static void ShowWindow(){var self = GetWindow(typeof(TimelineControl)) as TimelineControl;}private void OnGUI(){GUILayout.Space(7f);var dir = TimelineEditor.masterDirector;if (dir == null)return;if (GUILayout.Button("播放", GUILayout.Width(60f))){dir.Play();}if (GUILayout.Button("结束", GUILayout.Width(60f))){dir.Stop();}if (GUILayout.Button("暂停", GUILayout.Width(60f))){dir.Pause();}if (GUILayout.Button("恢复", GUILayout.Width(60f))){dir.Resume();}if (GUILayout.Button("前跳", GUILayout.Width(60f)))//根据播放模式不同，增加对应的帧或秒{dir.time += 1;RefreshData();}if (GUILayout.Button("后退", GUILayout.Width(60f)))//根据播放模式不同，减少对应的帧或秒{dir.time -= 1;RefreshData();}if (GUILayout.Button("重载刷新", GUILayout.Width(60f))){ReloadRefreshData();}if (GUILayout.Button("刷新界面", GUILayout.Width(60f))){RefreshGUI();}}/// <summary>/// 只刷新数据/// </summary>public void RefreshData(){var dir = TimelineEditor.masterDirector;if (dir == null)return;dir.Evaluate();}/// <summary>/// 重新加载Timeline数据，并恢复到当前帧/// </summary>public static void ReloadRefreshData(){var dir = TimelineEditor.masterDirector;if (dir == null)return;double oldT = dir.time;dir.Stop();dir.time = oldT;dir.Evaluate();}/// <summary>/// 通过反射刷新Timeline编辑窗口/// </summary>public static void RefreshGUI(){Assembly asmTE = Assembly.GetAssembly(typeof(TimelineEditor));var tw = asmTE.GetType("UnityEditor.Timeline.TimelineWindow");var gui = EditorWindow.GetWindow(tw, false);var twState = tw.GetProperty("state", BindingFlags.Instance | BindingFlags.Public);var stateValue = twState.GetValue(gui, null);var ws = asmTE.GetType("UnityEditor.Timeline.WindowState");var refreshMethod = ws.GetMethod("Refresh", BindingFlags.Instance | BindingFlags.Public);refreshMethod.Invoke(stateValue, new Object[] { });}
}

Track操作

实现动态添加一个ActivationTrack以及ActivationClip的功能

调用TimelineControl中的刷新函数，可以实现实时更新的效果

using UnityEditor;
using UnityEditor.Timeline;
using UnityEngine;
using UnityEngine.Timeline;public class TrackControl : EditorWindow
{[MenuItem("Tools/TrackControl")]private static void ShowWindow(){var self = GetWindow(typeof(TrackControl)) as TrackControl;}private void OnGUI(){if (GUILayout.Button("添加Track", GUILayout.Width(70f))){AddTrack();}if (GUILayout.Button("添加Clicp", GUILayout.Width(60f))){AddClip();}        }/// <summary>/// 添加时间轨/// </summary>private void AddTrack(){var t = TimelineEditor.masterAsset;var x = t.CreateTrack<ActivationTrack>(null, "Track") as ActivationTrack;TimelineEditor.Refresh(RefreshReason.ContentsAddedOrRemoved);}/// <summary>/// 添加剪辑/// </summary>private void AddClip(){var t = TimelineEditor.masterAsset;foreach(var tttt in t.GetRootTracks()){if (tttt is ActivationTrack)//获得第一个ActivationTrack轨道{var clip = tttt.CreateDefaultClip();clip.start = 6;clip.duration = 1;TimelineControl.ReloadRefreshData();break;}}        }      
}
