Namespace UnityEditor.Timeline.Actions

Classes

ActiveInModeAttribute

Define the activeness of an action depending on its timeline mode.

ApplyDefaultUndoAttribute

Use this attribute on action classes (TimelineAction, ClipAction, MarkerAction and TrackAction) to have the default undo behaviour applied.

By default, applying this attribute will record all objects passed to the Execute method with the Undo system, using the name of Action it is applied to.

Simple track Action example (with context menu and shortcut support).

[ApplyDefaultUndo]
public class SetNameToTypeAction : TrackAction
{
    public abstract ActionValidity Validate(IEnumerable<TrackAsset> items)
    {
        return ActionValidity.Valid;
    }
public override bool Execute(IEnumerable<TrackAsset> items)
{
    foreach (var track in items)
        track.name = track.GetType().name;
    return true;
}

}
