Functions

This page lists all the global functions that you can use with localscripts in the script builder.

Any global function that are not listed here that is otherwise normally a part of Roblox should keep their vanilla behavior.

print

print(...: any): void

Prints into the script builder output instead of the Roblox one. If the format printing setting is enabled then it will format the message with repr.

warn

warn(...: any): void

Warns into the script builder output instead of the Roblox one. If the format printing setting is enabled then it will format the message with repr.

error

error(message: any, level: number?): void

Throws an error, if the format printing setting is enabled then it will format the message with repr. Script errors are automatically caught by the script builder and outputted into your output.

printf

printf(...: any): void

Prints into the script builder output with richtext enabled, ignoring the format printing setting. Useful if you want to print information to the user into the output.

warnf

warnf(...: any): void

Warns into the script builder output with richtext enabled, ignoring the format printing setting. Useful if you want to warn information to the user into the output.

printidentity

printidentity(prefix: string?): void

Exactly like printidentity on Roblox but will always print identity 2, and outputs into the script builder output.

This is a deprecated Roblox function, and should not be used in new work. It's just added for compatibility.

NewScript([[
local var1, var2, var3 = ...
printf("var1:", var1)
printf("var2:", var2)
printf("var3:", var3)
]], workspace, "Hello I'm a string", Instance.new("Part", workspace), {"Tables work too!"})

NS

Alias for NewScript.

NewLocalScript

NewLocalScript(source: string, parent: Instance?, ...any): LocalScript

Creates and returns a new LocalScript with the specified source under the specified parent, with optional run arguments.

NewLocalScript([[
printf("Hello World! I'm in", script:GetFullName())
]])

]], nil, "Hello I'm a string", Instance.new("Part", workspace), {"Tables work too!"})
-- Pass nil as the parent if you want it to go to the default location.

Creates a new local script in your player gui to send your key inputs to the server.

local Remote = Instance.new("RemoteEvent")
Remote.Name = "Input"
Remote.Parent = script

NewLocalScript([[
local UserInputService = game:GetService("UserInputService")
local Remote = ...

UserInputService.InputBegan:Connect(function(Input)
    if UserInputService:GetFocusedTextBox() ~= nil then -- Don't send if typing.
        return
    end

        return
    end
    
    Remote:FireServer(Input.KeyCode)
end)
]], nil, Remote)
-- Parents the LocalScript to the default location and gives it the RemoteEvent.

Remote.OnServerEvent:Connect(function(Player, KeyCode)
    if Player ~= owner then -- We don't want other players spoofing!
        return
    end
    
    if typeof(KeyCode) ~= "EnumItem" then
        return
