splines-container-create	Create a new GameObject with a `SplineContainer` (and one initial empty `Spline`) in the active scene. Optionally set name, position and rotation. Returns the new GameObject reference and instanceId.	generated-by mcp-plugin-dotnet

Splines / Create Container

Create a new GameObject hosting a SplineContainer component in the active scene. The SplineContainer is the authoring component that holds one or more Splines; this tool seeds it with a single empty spline ready for knots.

Inputs

• name — optional GameObject name (default Spline).
• position — optional world Vector3 position (default zero).
• rotation — optional euler-degrees Vector3 rotation (default zero).
• closed — optional; when true the seeded spline is a closed loop (default false).

Behavior

Creates the GameObject, adds a SplineContainer with one empty spline, applies transform and the Closed flag, marks the scene dirty, repaints the Editor, and returns the new GameObject reference and instanceId. The whole call runs on the Unity main thread.

How to Call

unity-mcp-cli run-tool splines-container-create --input '{
  "name": "string_value",
  "position": "string_value",
  "rotation": "string_value",
  "closed": false
}'

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

unity-mcp-cli run-tool splines-container-create --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-tool splines-container-create --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
name	string	No	Name of the new SplineContainer GameObject.
position	any	No	World-space position of the GameObject.
rotation	any	No	World-space rotation of the GameObject in euler angles (degrees).
closed	boolean	No	If true, the seeded spline is a closed loop.
