timeline-clip-move	Move a clip along its track — either to an absolute `start` time or by a relative `deltaSeconds`. Duration is preserved.	generated-by mcp-plugin-dotnet

Timeline / Move Clip

Reposition a clip on its track without changing its duration. Provide either an absolute start or a relative deltaSeconds (delta is ignored when start is supplied).

Inputs

• assetPath — required path to the .playable TimelineAsset.
• trackName / trackIndex — which track holds the clip (name wins; index default 0).
• clipIndex — required zero-based clip index.
• start — optional absolute new start time (seconds).
• deltaSeconds — optional relative shift (seconds); used only when start is null.

Behavior

Computes the new start (clamped to >= 0), sets clip.start, saves the asset, and returns the old and new start. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool timeline-clip-move --input '{
  "assetPath": "string_value",
  "clipIndex": 0,
  "trackName": "string_value",
  "trackIndex": 0,
  "start": "string_value",
  "deltaSeconds": 0
}'

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

unity-mcp-cli run-tool timeline-clip-move --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool timeline-clip-move --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
assetPath	string	Yes	Assets-rooted path to the TimelineAsset (.playable).
clipIndex	integer	Yes	Zero-based index of the clip on its track.
trackName	string	No	Name of the track holding the clip. Takes precedence over trackIndex.
trackIndex	integer	No	Zero-based root-track index, used when trackName is null/empty.
start	any	No	Optional absolute new start time in seconds.
deltaSeconds	number	No	Optional relative shift in seconds; used only when start is null.
