Metatable — Velocity

getrawmetatable(value: any) → table?

Metatable ignoring the __metatable field.

lua

local mt = getrawmetatable(game)
print(mt.__namecall)

setrawmetatable(value: any, mt: table) → any

Replace the metatable (bypasses __metatable protection).

lua

local t = setmetatable({}, { __metatable = "locked" })
setrawmetatable(t, { __index = function() return 0 end })

setreadonly(t: table, readonly: boolean)

Set the readonly flag on a Luau table.

lua

local mt = getrawmetatable(game)
setreadonly(mt, false)
mt.__namecall = function() end
setreadonly(mt, true)

isreadonly(t: table) → boolean

Whether the table is currently readonly.

lua

print(isreadonly(getrawmetatable(game)))  --> true

makewriteable(t: table)

Shorthand for setreadonly(t, false).

lua

makewriteable(getrawmetatable(game))

makereadonly(t: table)

Shorthand for setreadonly(t, true).

lua

makereadonly(myTable)

getnamecallmethod() → string?

Inside a __namecall handler, the method name being invoked.

lua

hookmetamethod(game, "__namecall", function(self, ...)
    if getnamecallmethod() == "Kick" then return end
    return oldNamecall(self, ...)
end)

setnamecallmethod(name: string)

Rewrite the namecall method name.

lua

-- inside a __namecall hook, redirect Kick → Chat
if getnamecallmethod() == "Kick" then
    setnamecallmethod("Chat")
end
