Timeline Skills

Overview

Create and modify Unity Timelines.

Common Mistakes

DO NOT (common hallucinations):

• Package not installed → recipes silently fail; install first: Unity_PackageManager_ExecuteAction with packageId=com.unity.timeline, action=Add
• timeline_create_animation / timeline_add_track do not exist → use the typed track skills: timeline_add_animation_track, timeline_add_audio_track, timeline_add_activation_track, timeline_add_control_track, timeline_add_signal_track
• timeline_add_keyframe does not exist → Timeline uses clips, not direct keyframes; use timeline_add_clip
• timeline_set_duration sets the Timeline asset duration, not individual clip duration

Routing:

• For Animator parameters/states → use animator module
• For runtime animation playback → use editor_play or write C# via script module
