Global Functions

Built-in global functions available in the LuaVM environment.

Function	Description
print(...)	Outputs to console with `[print]` prefix
warn(...)	Outputs to console with `[warn]` prefix
error(...)	Throws a Lua error
hex(number)	Formats a number as hex string (e.g. `0x7FF...`)
tick()	Returns `GetTickCount64()` — milliseconds since system start
loadstring(source)	Loads and compiles Lua source code. Returns `(function, nil)` on success or `(nil, error_message)` on failure.
type(v)	Overrides Lua's built-in `type()`. Behaves normally for all Lua values, and additionally recognizes Roblox Luau GC addresses returned by `cheat.getgc()`/`cheat.rawget()` — for a number that points at a live GC object it returns `"table"`, `"string"`, `"function"`, `"userdata"`, or `"thread"` depending on the object's type.

String Extensions

Appended to Lua's built-in string library:

Function	Signature	Description
string.regex(text, pattern)	`string, string`	Returns `true` if the pattern is found (std::regex_search). Returns `false` on invalid patterns.

Example

-- string.regex
if string.regex("hello123", "%d+") then
    print("contains digits")
end
​
-- type() also recognizes external Roblox GC addresses
local gc = cheat.getgc()
for _, t in next, gc do
    if type(t) == "table" then
        -- t is a number (Roblox table's memory address), but
        -- type() reports "table" because it dereferences the GC header.
    end
end

base64

Base64 encoding and decoding. Always available (no library gate).

Function	Signature	Description
base64.Encode(data)	`string`	Encodes a string to base64
base64.Decode(data)	`string`	Decodes a base64 string back to plaintext

Example

local encoded = base64.Encode("Hello, world!")
print(encoded)  -- SGVsbG8sIHdvcmxkIQ==
local decoded = base64.Decode(encoded)
print(decoded)  -- Hello, world!

hash

Cryptographic hash functions. Always available (no library gate).

Function	Signature	Description
hash.Sha256(data)	`string`	Returns SHA-256 hex digest
hash.Sha3(data)	`string`	Returns SHA-3 hex digest
hash.Md5(data)	`string`	Returns MD5 hex digest

Example

local sha = hash.Sha256("hello")
print(sha)  -- 2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824

compress

LZ4 compression utilities. Always available (no library gate).

Function	Signature	Description
compress.Compress(data)	`string`	Compresses data using LZ4 (does NOT prepend original size). `Decompress` expects a 4-byte size header — functions are currently incompatible.
compress.Decompress(data)	`string`	Decompresses LZ4-compressed data back to original.

Example

local comp = compress.Compress("Hello, world!")
local dec = compress.Decompress(comp)
print(dec)  -- Hello, world!

task

Scheduling utilities for asynchronous execution.

Function	Signature	Description
task.spawn(fn)	`function`	Schedules `fn` to run asynchronously
task.delay(seconds, fn)	`number, function`	Schedules `fn` after `seconds`
task.wait(seconds)	`number`	Yields the coroutine, returns actual elapsed time. Must be called within a `task.spawn`'d or yielded coroutine (not from main thread).

Example

task.spawn(function()
    print("Runs asynchronously!")
end)
​
local elapsed = task.wait(1)
print("Waited", elapsed, "seconds")

tween

Interpolate instance properties smoothly over time. Modelled on Roblox's TweenService.

Function	Signature	Description
tween.Info(time, delayTime?, style?)	`number, number?, string?`	Builds a TweenInfo table. `style` defaults to `"Linear"`, `delayTime` to `0`. You can also pass a raw table `{time=..., delayTime=..., style=...}` anywhere info is expected.
tween.Create(instance, info, props)	`Instance, table, table`	Creates a tween that will interpolate each property in `props` from its current value to the target value. Returns a tween object.

Tween Object

Method	Signature	Description
tween:Play(waitForFinish?)	`bool?`	Starts the tween. When `waitForFinish` is `true`, blocks the calling coroutine until every property has finished tweening; otherwise returns immediately. Both `tween:Play(...)` and `tween.Play(...)` syntaxes are accepted.
tween:Cancel()		Snaps every property back to the value it had when the tween was created. Does not stop already-scheduled ticks — for that, let the tween finish or overwrite the property.

Easing Styles

Linear, Bounce, Elastic, Exponential, Cubic. Also exposed as tween.EasingStyle.Linear etc. for readability. Pass either the string or the constant.

Supported Property Types

number — e.g. Transparency, Reflectance, WalkSpeed
Vector3 — e.g. Position, Size, LinearVelocity, AngularVelocity
Color3 — e.g. Color

The property must be registered for the instance's class (see Class Properties) and must not be read-only. Unsupported properties raise an error at tween.Create time.

Example — Move a part

local part = workspace.Part
local info = tween.Info(1.5, 0, "Cubic")
​
local t = tween.Create(part, info, {
    Position = Vector3.new(0, 20, 0),
    Transparency = 0.5,
})
​
t:Play()

Example — Wait until finished

local part = workspace.Part
​
local t = tween.Create(part, { time = 2, style = "Bounce" }, {
    Position = part.Position + Vector3.new(0, 15, 0),
})
​
t:Play(true)
print("Tween finished — running follow-up code")

Example — Chained tweens

task.spawn(function()
    local part = workspace.Part
    local up   = tween.Create(part, tween.Info(1, 0, "Cubic"),  { Position = part.Position + Vector3.new(0, 10, 0) })
    local down = tween.Create(part, tween.Info(1, 0, "Bounce"), { Position = part.Position })
​
    up:Play(true)
    down:Play(true)
end)

Notes

Each property tweens independently. Passing multiple properties runs them in parallel on the same schedule.
tween:Play(true) blocks the calling coroutine — use task.spawn if you don't want to freeze your main script.
Tweens write directly to memory. Physics-driven properties (Position, CFrame, velocities) update visually but the engine may resimulate them next physics step; combine with anchoring or velocity-zeroing for full control.
Tween ticks run on a dedicated background thread and continue even if the script yields.

memory

Raw memory read/write operations. Requires the Memory library to be enabled.

Requires: Memory library enabled

Function	Signature	Description
memory.Read(type, address)	`string, uintptr`	Reads from memory
memory.Write(type, address, value)	`string, uintptr, any`	Writes to memory
memory.GetRTTI(address)	`uintptr`	Gets RTTI type from vtable
memory.GetBase()		Returns Roblox process base address
memory.Rebase(offset)	`uintptr`	Returns `base + offset`

Supported Types

Read/Write: float, double, int, uint, bool, byte, short, ushort, int64, uint64, string, vector2, vector3, color3.

Write also supports: pointer.

Example

local base = memory.GetBase()
local value = memory.Read("int", base + 0x1234)
print(hex(value))
memory.Write("int", base + 0x1234, 999)

cheat

Cheat utilities — event registration, raycasting, server/teleport helpers, and the Roblox Luau garbage-collector interface.

Events

Function	Signature	Description
Register(eventType, fn)	`string, function`	Register a callback for an event type. Fires for the lifetime of the script until unregistered.
Unregister(eventType, fn)	`string, function`	Unregister a previously registered callback. Pass the same function reference used with `Register`.

Event Types

Event	Description
onPaint	Fires every frame for rendering
onUpdate	Fires every frame for logic updates
onSlowUpdate	Fires at a reduced rate
teleport	Fires when the player teleports

Example

local function onPaint()
    draw.Text("ESP Label", 100, 50, Color3.new(1, 1, 0))
end
​
cheat.Register("onPaint", onPaint)
​
-- Later, stop drawing:
cheat.Unregister("onPaint", onPaint)

Garbage Collector

Read and write the target process's Luau GC directly. getgc enumerates live objects; rawget/rawset operate on a single external table by address; setgc writes across every table that has a key.

Function	Signature	Description
getgc(includeAll?, searchKey?)	`bool?, string?`	Enumerates the target process's Luau GC. Default returns tables only; pass `true` as the first arg to include strings, functions, userdata, and threads. If `searchKey` is a non-empty string, `getgc` instead scans every GC table for that key and returns the first non-nil value it finds — decoded to a Lua value (`string`/`number`/`boolean`) where possible, or the raw address as a `number` for GC-typed values. Returns `nil` if no table has the key.
setgc(key, value)	`string, bool \| number \| address`	Iterates every GC table and writes `value` into every table that already has `key`. Accepts `bool`, `number`, or a GC address (the tt is inferred from the GC object's header). Cannot create new keys and does not issue a GC write barrier. String literals are rejected — pass an existing TString address (a `number`) instead.
rawget(addr, key \| true)	`number, string \| bool`	Reads a field on the external table at `addr`. 2nd arg: pass a `string` key to fetch a single field, or pass `true` to dump the whole table as a Lua table. Missing keys return `nil`. Returned GC-typed values (tables/functions/userdata) come back as their raw address `number`; call `rawget` recursively on them to dive deeper.
rawset(addr, key, value)	`number, string, any`	Writes an existing field on the external table at `addr`. Accepts `nil`, `bool`, `number`, or an address for GC-typed values (the tt is inferred from the GC object's header). Returns `true` on success, `false` if the key doesn't already exist. Cannot create new keys and does not issue a GC write barrier.

Example

-- GC enumeration + rawget / rawset (Roblox Luau)
--   Find every weapon config and give it unlimited ammo.
for _, t in next, cheat.getgc() do
    if type(t) == "table"
       and cheat.rawget(t, "MaxAmmo") ~= nil then
        cheat.rawset(t, "MaxAmmo",     math.huge)
        cheat.rawset(t, "CurrentAmmo", math.huge)
    end
end
​
-- Shortcut: getgc(includeAll, searchKey) walks the GC for you
--   and returns the first table's value for that key, or nil.
local ammo = cheat.getgc(false, "MaxAmmo")
if ammo then print("first MaxAmmo seen =", ammo) end
​
-- setgc(key, value) writes into every GC table that has the key.
--   One-liner replacement for the loop above:
cheat.setgc("MaxAmmo",     math.huge)
cheat.setgc("CurrentAmmo", math.huge)
​
-- Dump every field on a table (debugging).
local dump = cheat.rawget(someAddr, true)
for k, v in pairs(dump) do print(k, "=", v) end

Raycast

Function	Signature	Description
Raycast(pos, dir, distance, ignoreTransparent?)	`Vector3, Vector3, number, bool?`	Casts a ray. Returns `(hit, instance, position, distance)`.

Example

local hit, inst, pos, dist = cheat.Raycast(
    Vector3.new(0, 5, 0),
    Vector3.new(0, -1, 0),
    500
)
​
if hit then
    print("hit", inst.Name, "at", pos, "dist", dist)
end

Servers & Teleport

Function	Signature	Description
TeleportPlace(placeId, jobId?)	`string, string?`	Teleport to a Roblox place/server. Also accepts a table `{PlaceId, JobId}`. Returns `bool`.
GetServers(placeId?)	`string?`	Fetches game server list. Returns table of servers with `JobId, PlaceId, UniverseId, GameName, Playing, MaxPlayers, Ping, Fps`. Defaults to current place.
GetUniverseId(placeId?)	`string?`	Gets universe ID for a place. Defaults to current place.

Example

-- Teleport to a place
local ok = cheat.TeleportPlace("123456789")
print("Teleport:", ok)
​
-- Get servers for current place
local servers = cheat.GetServers()
for _, srv in ipairs(servers) do
    print(srv.JobId, srv.Playing, "/", srv.MaxPlayers)
end

DragFloat / DragInt are draggable numeric fields. Drag horizontally to change the value; click without dragging to type a value directly. Hold Ctrl while dragging for finer steps (0.1×), Shift for coarser (10×).

speed — value change per pixel dragged (default 1).
min, max — clamp range. Leave both 0 (or equal) for an unbounded field.
format — printf-style, may include a suffix, e.g. "%.2f studs" or "%d rounds".
disabled — when true, the field is dimmed and ignores input.
DragFloat2 / DragFloat3 render a labeled property row with 2 / 3 boxes sharing one row's width — ideal for Vector2 / Vector3.

Instance

The core Roblox instance type. Access instances via game, Instance constructors, or methods.

Properties

Property	Type	Access	Description
Name	`string`	RW	Instance name
ClassName	`string`	RO	Class name
Parent	`Instance`	RW	Parent instance
Address	`uintptr`	RO	Raw memory address
FullName	`string`	RO	Full hierarchical path

Methods

Method	Returns	Description
:FindFirstChild(name)	`Instance\|nil`	Find first child by name
:WaitForChild(name, timeout?)	`Instance\|nil`	Wait for child to appear
:FindFirstChildOfClass(className)	`Instance\|nil`	Find first child of class
:FindDescendants(name)	`table`	Find all descendants by name
:FindDescendantsOfClass(className)	`table`	Find all descendants of class
:GetChildren()	`table`	Direct children
:GetDescendants()	`table`	All descendants
:Ancestors()	`table`	All ancestors
:IsDescendantOf(ancestor)	`bool`	Check ancestry
:IsA(className)	`bool`	Check class
:IsAncestorOf(descendant)	`bool`	Check if is ancestor
:GetAttributes()	`table`	Attribute table
:GetAttribute(name)	`string\|nil`	Get attribute
:SetAttribute(name, value)		Set attribute
:GetTags()	`table`	Collection tags
:HasTag(tag)	`bool`	Check tag
:RenameTag(oldName, newName)		Rename tag
:GetPropertyChangedSignal(property)	`RBXScriptSignal`	Returns a signal that fires when the given property changes

Example

local part = workspace.Part
local sig = part:GetPropertyChangedSignal("Position")
sig:Connect(function()
    print("Position changed!")
end)

Meta-Behavior

instance.PropertyName first checks built-in properties, then registered class properties, then falls back to child lookup by name.
Setting properties respects read-only flags.
instance.Changed returns an RBXScriptSignal that fires when any registered class property changes. Usage: instance.Changed:Connect(function(propertyName, newValue) ... end).
for k, v in pairs(instance) do ... end iterates over built-in properties, class properties, and children.

DataModel

Both game and Game resolve to the Roblox DataModel instance.

DataModel inherits from Instance, so all Instance methods are available.

GetService

Method	Returns	Description
:GetService(className)	`Instance\|nil`	Get service by class name

local Players = game:GetService("Players")
local RunService = game:GetService("RunService")

RemoteEvent

FireServer, InvokeServer, and bidirectional remote spy — extra members added to RemoteEvent, UnreliableRemoteEvent, and RemoteFunction instances.

These members appear on top of the standard Instance API for any instance whose ClassName matches. Reading a spy signal auto-installs the underlying hook on first read — you don't need to opt in ahead of time.

Remotes parented anywhere under RobloxReplicatedStorage are treated as protected — trying to access the spy on them errors with Protected <ClassName>.

Methods

Method	Applies to	Description
FireServer(...)	`RemoteEvent`, `UnreliableRemoteEvent`	Fires the remote to the server with the given args.
InvokeServer(...)	`RemoteFunction`	Invokes the remote against the server with the given args. Currently fire-and-forget — the server WILL reply but the return value is not routed back to Lua yet, so this returns `nil`. If you need the reply value, pair a `RemoteEvent` both directions instead.

Example

local rem = game:GetService("ReplicatedStorage").Events.MyEvent
rem:FireServer("hello", 42, true)
​
-- Instances, nested arrays, and string-keyed dicts are all supported.
rem:FireServer(
    game:GetService("Players").LocalPlayer,
    { 1, 2, 3 },
    { action = "buy", itemId = 7, meta = { source = "shop" } }
)
​
local func = game:GetService("ReplicatedStorage").Functions.RequestInventory
func:InvokeServer("get", { slot = 1 })  -- returns nil for now

Outgoing spy (client → server)

Fires whenever anything in the game (Lua, C++, other exploits) sends args from this client to the server through the remote. One shared hook per class covers every instance — the first read installs it.

Member	Type	Description
OnFireServer	`RBXScriptSignal`	Callback fires with the args when this `RemoteEvent` / `UnreliableRemoteEvent` is fired to the server.
OnServerEvent	`RBXScriptSignal`	Alias for `OnFireServer`.
OnInvokeServer	`RBXScriptSignal`	Callback fires with the args when this `RemoteFunction` is invoked against the server. `RemoteFunction` only.
OnServerInvoke	`RBXScriptSignal`	Alias for `OnInvokeServer`.

Example

local rem = game:GetService("ReplicatedStorage").Events.MyEvent
​
rem.OnFireServer:Connect(function(...)
    print("FireServer intercepted:", ...)
end)
​
-- :Wait() yields the coroutine and returns the next fire's args.
task.spawn(function()
    local a, b, c = rem.OnFireServer:Wait()
    print("first fire:", a, b, c)
end)
​
local func = game:GetService("ReplicatedStorage").Functions.GetInventory
func.OnInvokeServer:Connect(function(...)
    print("InvokeServer intercepted:", ...)
end)

Incoming spy (server → client)

Fires whenever the server sends args to this client through the remote. Hooked per-instance — the first read installs one shared hooked vtable per unique class-vptr, then every subsequent instance is cheap. Callback receives the args the server sent.

Member	Type	Description
OnClientEvent	`RBXScriptSignal`	Callback fires with the args when the server sends to this client through the `RemoteEvent` / `UnreliableRemoteEvent`.
OnClientInvoke	`RBXScriptSignal`	Callback fires with the args when the server invokes this `RemoteFunction` against the client. Purely observational — the connect does not assign a return value the server sees. `RemoteFunction` only.

Example

local rem = game:GetService("ReplicatedStorage").Events.MyEvent
​
rem.OnClientEvent:Connect(function(...)
    print("server -> client:", ...)
end)
​
local func = game:GetService("ReplicatedStorage").Functions.GetInventory
func.OnClientInvoke:Connect(function(...)
    print("server invoked us with:", ...)
end)
