| splines-set-closed | Toggle whether a spline is a closed loop. A closed spline connects its last knot back to its first, forming a continuous loop. |
|
Splines / Set Closed
Set the Closed flag of a spline.
Inputs
gameObjectRef— the GameObject hosting theSplineContainer(required).closed— true to close the loop, false to open it (default true).splineIndex— which spline in the container (default 0).
Behavior
Assigns Spline.Closed, marks the scene dirty, repaints, and returns the resulting state. Runs on the Unity main thread.
How to Call
unity-mcp-cli run-tool splines-set-closed --input '{
"gameObjectRef": "string_value",
"closed": false,
"splineIndex": 0
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool splines-set-closed --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool splines-set-closed --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.
