List the immediate nested prototypes compiled inside a Luau function. This helps you locate a child function before asking for its metadata or installing a proto hook.

Syntax

Luau

debug.getprotos(target: DebugTarget) -> {ProtoProxy}

Parameters

Function parameters
Parameter	Type	Description

DebugTarget = Function | number | ProtoProxy

Returns

{ProtoProxy}

An array of ProtoProxy objects in prototype order.

Example

Luau

local function factory()
    local function first() end
    local function second() end

for index, proto in ipairs(debug.getprotos(factory)) do
    print(index, debug.getinfo(proto).source)
