AI Splines

At a glance

What the agent can do with it

Adds no MCP tools: it contributes an RQL module with the splines source and adapters for SplineContainer. That powers 3 capabilities the agent reaches through rql-query / rql-mutate. How RQL works →

• Create splines

  Create SplineContainers (open or closed) and add or remove splines inside them.

  splines | call CreateContainer("Road", "(0, 0, 5)", "(0, 90, 0)", true)
• Knots & tangents

  Add, insert, move and remove knots, change tangent modes, and open or close a spline.

  splines | get containers | where gameObject.name == "Road" | call AddKnot("(1, 0, 2)")
• Points along a curve

  Get the position at any point along a spline (0 to 1) — handy for placing objects along a path.

  splines | get containers | where gameObject.name == "Road" | call Evaluate(0.5)

See it in the Unity catalog →

Install

Requires the base plugin com.ivanmurzak.unity.mcp. After installing, the RQL module loads with the package — the agent sees it in rql-schema.

When to ask the AI for it

Ask for paths, rails, patrol routes, or anything that follows a curve.

Example prompts

Copy-pasteable first requests. Start with one, verify it in the editor, then build up.

1. Create a closed-loop spline with 6 knots forming a rough circle of radius 5 around the origin.

2. Add a knot to the `Track` spline halfway along it and smooth its tangents.
