getscriptbytecode(script: Instance) → string

Raw compiled Luau bytecode for a Script/LocalScript/ModuleScript.

aliasesdumpstring

lua

local bc = getscriptbytecode(game.Players.LocalPlayer.PlayerScripts.MyScript)
writefile("MyScript.luac", bc)

getscripthash(script: Instance) → string?

SHA of the script's bytecode. nil for scripts whose bytecode isn't accessible.

lua

print(getscripthash(workspace.Script))

getscriptclosure(script: Instance) → function

Compile and return the script's top-level closure without running it.

aliasesgetscriptfunction

lua

local f = getscriptclosure(game.ReplicatedStorage.Module)
local module = f()

getcallingscript() → Instance?

The script that spawned the currently-running thread.

lua

print(getcallingscript() and getcallingscript():GetFullName())

getscripts() → {Instance}

All Scripts, LocalScripts, and ModuleScripts in the DataModel.

lua

for _, s in ipairs(getscripts()) do
    if s.Name:match("Anticheat") then print(s:GetFullName()) end
end

getloadedmodules() → {Instance}

Only ModuleScripts that have been require()d.

lua

print(#getloadedmodules(), "modules loaded")

getrunningscripts() → {Instance}

Scripts whose top-level thread is still alive.

lua

for _, s in ipairs(getrunningscripts()) do print(s.Name) end

getsenv(script: Instance) → table

The environment table of a Script/LocalScript.

lua

local env = getsenv(game.Players.LocalPlayer.PlayerScripts.Main)
print(env.myLocal)

getmenv(module: ModuleScript) → table

The environment table of a require()d ModuleScript.

lua

local menv = getmenv(game.ReplicatedStorage.SharedModule)
print(menv._VERSION)

decompile(script: Instance) → string

Best-effort decompilation of a script's bytecode.

lua

print(decompile(workspace.Script))

setscriptable(instance: Instance, property: string, scriptable: boolean) → boolean

Flip a property's Scriptable flag in-memory. Returns the previous value.

lua

setscriptable(workspace.Camera, "Focus", true)
print(workspace.Camera.Focus)

isscriptable(instance: Instance, property: string) → boolean

Whether a property is currently marked Scriptable.

lua

print(isscriptable(workspace.Camera, "Focus"))

gethiddenproperty(instance: Instance, property: string) → any, boolean

Read a property regardless of Scriptable flag. Returns (value, isHidden).

lua

local val, hidden = gethiddenproperty(workspace.Terrain, "PhysicsGrid")
print(hidden, #val)

sethiddenproperty(instance: Instance, property: string, value: any) → boolean

Write a property regardless of Scriptable flag. Handles complex types (CFrame, ColorSequence, BinaryString, Enum, Content, etc.).

lua

sethiddenproperty(workspace.Part, "size", Vector3.new(10, 10, 10))
