Rive Luau
Language intelligence for Rive's Luau scripting environment — rich tooltips, autocomplete, real-time diagnostics, and IntelliSense designed for artists and designers learning to code.
Features
Every type, method, property, and parameter has detailed hover documentation written in plain English — not terse technical jargon. Tooltips explain what things do, why you'd use them, and how with practical examples.
drawPath — "Render a shape on screen. This is the core drawing call.
You give it two things: path (what to draw) and paint (how it looks)."
clipPath — "Mask all future drawing to only appear inside this shape.
Like cutting a hole in paper — only the area inside is visible."
BlendMode — "Controls how overlapping shapes blend together —
like Photoshop layer blend modes."
Autocomplete
Context-aware suggestions for:
- The entire Rive scripting API — Vector, Color, Path, Paint, Renderer, Mat2D, ViewModel, and 40+ more types
- All Luau standard library functions — math, string, table, bit32, coroutine, and more
- Your own variables, functions, and types
Real-Time Diagnostics
Catches errors as you type:
- Type mismatches
- Missing required properties
- Undefined variables and functions
- Incorrect function arguments
Go-to-Definition
Jump to where any symbol is defined with Cmd+Click / Ctrl+Click.
Syntax Highlighting
Full Luau grammar support including syntax highlighting inside Markdown code blocks.
Custom File Icon
.luau files display a custom Rive script icon in the VS Code explorer, tabs, and breadcrumbs.
