Timeline / Bind PlayableDirector

Assign a TimelineAsset as the playable of a scene PlayableDirector so the timeline can be played at runtime/in the editor. If the GameObject has no PlayableDirector, one is added.

Inputs

  • gameObjectRef — the scene GameObject to host/own the PlayableDirector (required).
  • assetPath — the .playable TimelineAsset to bind (required).
  • playOnAwake — optional flag to set PlayableDirector.playOnAwake.

Behavior

Resolves the GameObject, ensures a PlayableDirector, sets playableAsset to the loaded TimelineAsset, applies playOnAwake when provided, marks the scene dirty, and returns the director GameObject reference + instanceId. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool timeline-director-bind --input '{
  "gameObjectRef": "string_value",
  "assetPath": "string_value",
  "playOnAwake": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

unity-mcp-cli run-tool timeline-director-bind --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool timeline-director-bind --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead. Read the /unity-initial-setup skill for detailed installation instructions.

Input

Name Type Required Description
gameObjectRef any Yes Reference to the scene GameObject that should own the PlayableDirector.
assetPath string Yes Assets-rooted path to the TimelineAsset (.playable) to bind.
playOnAwake any No Optional value for PlayableDirector.playOnAwake.
