Custom inspector editor for timeline clips?

Any chance we're going to be able to write custom editors for our clips in the tracks? It would really come in handy ... if we're already able to, please let me know how .

 

Yeah, we can already do it.

Code (CSharp):

1. using UnityEngine.Playables;
2.  
3. [CustomPropertyDrawer(typeof(EnemyControlBehaviour))]
4. public class EnemyControlDrawer : PropertyDrawer
5. {
6.     public override float GetPropertyHeight (SerializedProperty property, GUIContent label)
7.     {
8.         int fieldCount = 1;
9.         return fieldCount * EditorGUIUtility.singleLineHeight;
10.     }
11.  
12.     public override void OnGUI (Rect position, SerializedProperty property, GUIContent label)
13.     {
14.         SerializedProperty prefab = property.FindPropertyRelative("prefab");
15.         SerializedProperty color = property.FindPropertyRelative("color");
16.  
17.         Rect singleFieldRect = new Rect(position.x, position.y, position.width, EditorGUIUtility.singleLineHeight);
18.         EditorGUILayout.PropertyField(prefab);
19.         EditorGUILayout.PropertyField(color);
20.     }
21. }

This is one of mine. It's messy because I rushed it without actually reading what it was doing at first, but it works. The way he does in the video looks better, I think.

 

Woah had no idea this was implemented. Thank you sooo much.

 

How to do this for a track? I've got it only the clips.. works well; but I'd love to be able to do this on a track

 

I know it's an old post, but it's something I am struggling with at the moment.
In general I understand the idea.
But I would like to combine two worlds.

Ability to record animations (example 4 from https://blogs.unity3d.com/2018/09/05/extending-timeline-a-practical-guide/)
And custom editor.
If I follow the property drawer idea, yes I can override the inspector, but I can no longer record animations on that clip/behaviour inspector.
The red(record) button is visible and I can click it but no key frames can be recorded.

Before, with the automatic editor and the fact it generated "template" fields out of the box, I could record animations on clip inspector.
For now I need to choose, ability to record animation from clip inspector with automatic template fields generations or custom clip editor.

Is it me or maybe there is something missing in the video example?


[Update]
In general I only need to add some graphical element base on values so I can display default inspector and some added bits. Don't need to change any values in my custom editor bit.

 

After some more digging I realized that extending behaviour editor wasn't the issue.
Looks like I can't really record animations on none float variables.
Maybe it has somethign to do with mixer and the fact there are calculations on float for input weight etc.
Sorry, my issue is not related to the custom behaviour editor.

 

I'm unable to write PropertyDrawer for my TimelineBehaviour with script AndrewKaninchen provided. I also tried to bind PropertyDrawer to MyCustomClip. I found no other info about it.

I'm also very interested in how AudioTrack drawing custom grapics (audio track presentation) over clips in Timeline window. I'm just curious, I bet I'll come up with some interesting ideas with custom graphics and ui elements over clips
At least I hope when timeline will be available as package we'll be able to dig it through and see how it's acheived

 

Oh dang it was really stupid tiny mistake I made. I figured out how to write PropertyDriwer

 

What a great future is coming I'm hacking into Timeline extensively in my current project. With tracks generation and manipulation through custom node editor. It's cool to hear there is more to come. I love how we may extend some tools in unity in a ways it not intended to be used

 

Hey Sean, would have some sample code on how to extend the markers? I've written a custom inspector for my new marker (derived from the standard "Editor" inspector class) in order to add some QoL improvements on top of the default inspector behavior. I've overriden OnInspectorGUI() and called DrawDefaultInspector() from it but I'm not getting the same behavior as the Unity default. For instance, I can no longer edit the marker name in the inspector header (I have a workaround but it's not ideal):



And this how it looks using the default marker inspector:


I figured I should probably derive my custom inspector from something like a more specialized "MarkerEditor" base class but this one doesn't seem to derive from the base Editor inspector class.

Any pointers please?

 

Thanks for the detailed answer, sean! I can easily work around the title bar renaming feature by simply adding a custom text field to my inspector to update name property of the marker, but yeah it's not ideal. I'll give the property drawer approach a go, but in my case I would like to control the visibility of several fields depending on the value of an enum property so I'm not sure this approach would work here.

 

@seant_unity while I've got you on the line... is there an equivalent of Marker.parent (TrackAsset) for timeline clips in the editor? I'm trying to do a custom inspector for a new timeline clip that has a property that should list markers on the timeline the clip is on. Unfortunately the PlayableAsset class from which my custom clip derives from does not know about the timeline track it's on, so I cannot enumerate the markers it contains.

Is there a more specialized base-class to derive from for timeline clips? As in, the equivalent of the Marker class but for clips?
