splines-get-knots	Read all knots of a spline in a `SplineContainer`: per-knot position, in/out tangents, rotation, and tangent mode, plus the closed flag. Read-only.	generated-by mcp-plugin-dotnet

Splines / Get Knots

Inspect the knots of a specific spline. Useful before editing to know the indices, positions, and tangent modes.

Inputs

• gameObjectRef — the GameObject hosting the SplineContainer (required).
• splineIndex — which spline in the container (default 0).

Behavior

Enumerates every knot of the chosen spline and returns a per-knot summary plus the spline's Closed flag. Read-only. Runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool splines-get-knots --input '{
  "gameObjectRef": "string_value",
  "splineIndex": 0
}'

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

unity-mcp-cli run-tool splines-get-knots --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool splines-get-knots --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 GameObject containing the SplineContainer component.
splineIndex	integer	No	Index of the spline inside the container (default 0).
