IntelliJ: Install the EmmyLua2 plugin

See the Editor Setup guide for detailed instructions.

Start Coding

Create a Lua file and start using EmmyLua annotations:

example.lua

---@class Vector3
---@field x number
---@field y number
---@field z number

---@param a Vector3
---@param b Vector3
---@return Vector3
function add(a, b)
    return {
        x = a.x + b.x,
        y = a.y + b.y,
        z = a.z + b.z
    }
end

You’ll immediately get auto-completion, type checking, and inline documentation.
