DebuggerManager

The DebuggerManager class allows you to manage Sentinel’s Roblox Lua debugger. Look here to learn how to use it.

appendfile

Documentation

void appendfile(<string> filename, <string> data)

Description

If filename exists in the workspace folder, data is appended to the end of the file. If the file doesn’t exist, it writes to a new file. This function is restricted to the workspace folder.

Example

File: test.txt

Hello

Script

appendfile("test.txt", " World!")

File: test.txt

Hello World!

Note: If you replaced appendfile with writefile in the script, the file would be overwritten instead of appended to.

checkcaller

Documentation

boolean checkcaller()

Description

Returns true if the current thread was made by Sentinel and false if the current thread was not made by Sentinel.

Example

print(checkcaller()) -- true

Additional Notes

If you were to hook a function which comes from a script inside the game and make your hook call checkcaller , you would get a false result.

createdirectory

Documentation

void createdirectory(<string> name)

Description

Creates a directory in the workspace folder with the name name. If the directory already exists, an error occurs.

Example

createdirectory("test")

fireclickdetector

Documentation

void fireclickdetector(<ClickDetector> d)

Description

Simulates a click on ClickDetector d.

Example

fireclickdetector(game.Workspace.Button.ClickDetector)

Note: The example above doesn’t apply to every situation and is just an example of the values you might call the function with.

getcallingscript

userdata getcallingscript()

Description

Returns the script that is calling the current function. If called within Sentinel, it will return nil.

Example

print(getcallingscript()) --> nil

getconnections

Documentation

table getconnections(<RBXScriptSignal> event)

Description

Returns the functions connected to event as a table. Each entry in the returned table is a table with Enable and Disable methods. You can call those methods to enable/disable connections.

Example

Additional Notes

As you saw in the above example, getgenv can be used to add functions to the global environment which can be used across all scripts and tabs.

getinstancecachekey

Unfortunately, I don’t know how to use this.

getloadedmodules

Documentation

table getloadedmodules()

Description

Returns a table containing the loaded ModuleScripts in the game.

Example

for k,v in pairs(getloadedmodules()) do print(k,v)end

Additional Notes

Keep in mind that the returned table uses numeric indices as keys so you will have to use a conditional statement to search for certain ModuleScripts.

getmenv

This function is identical to getsenv. Click here to jump to that page.

getnamecallmethod

Documentation

string getnamecallmethod()

Description

Returns the name of the method being called on an instance as a string. This only works when used within a __namecall hook.

Example

Example

Note: This example only works in Prison Life

local env = getsenv(game.Players.LocalPlayer.Character.ClientInputHandler)for k,v in pairs(env) do print(k,v)end

Additional Notes

Keep in mind that every script’s global environment table contains a global called script which is the current script.

getspecialinfo

Documentation

table getspecialinfo(<UnionOperation> u)

Description

Returns a table containing the special information of a UnionOperation instance u.

Example

-- to use this example, find a UnionOperation with Dex in a game and replace the pathfor k,v in pairs(getspecialinfo(workspace.Plant.Model.Union)) do print(k,v)end

Documentation

boolean issentinelclosure(<function> closure)

Description

Returns true if closure originates from Sentinel.

Example

Note: The second line returns false because print originates from Lua’s global environment.

keypress

Documentation

void keypress(<number> keycode)

Description

Continuously presses the key indicated by keycode until keyrelease is called with the same keycode.

Example

wait(1) -- gives you some time to click on the Roblox windowkeypress(0x20) -- press spacebarwait()keyrelease(0x20) -- release spacebar

Additional Notes

To see a list of keycodes, visit this link: https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes

Make sure to add a delay between the call to keypress and keyrelease or else the input will be too fast for your computer to register. Use wait() for a very short delay.

keyrelease

Documentation

void keyrelease(<number> keycode)

Description

Releases the key indicated by keycode if it’s being held down (via keypress).

Example

wait(1) -- gives you some time to click on the Roblox windowkeypress(0x20) -- press spacebarwait()keyrelease(0x20) -- release spacebar

Additional Notes

To see a list of keycodes, visit this link: https://docs.microsoft.com/en-us/windows/win32/inputdev/virtual-key-codes

Make sure to add a delay between the call to keypress and keyrelease or else the input will be too fast for your computer to register. Use wait() for a very short delay.

loadfile

Documentation

function,<nil,string> loadfile(<string> filename)

Documentation

function,<nil,string> loadstring(<string> source [,<string> chunkname])

Description

Compiles a Lua function from string and returns it. If any errors are produced, nil is returned plus the error message as a string.

Example

print(loadstring("print('hi')")) --> function: 0xADDRprint(loadstring("lol")) --> nil [string "lol"]:1: `=` expected near `<eof>`loadstring("print('hi'))")() --> hi

messagebox

Documentation

int messagebox(<string> title, <string> caption, <int> options)

Description

Creates a Windows message box with the title set to title and the caption set to caption. When the message box is created, Roblox is paused in the background and the script is yielded until a button or X is clicked. The default message box just has an OK button but you can add an icon and change the buttons using the options argument. The integer returned by the function is based on which button you press on the message box.

Example

messagebox("Sentinel Message!", "Hello there!")

messagebox("Sentinel Message!", "Hello there!", 0x35)

Additional Notes

The options argument is a hexadecimal number and each digit indicates a specific option. You can view all available options at the official documentation: https://docs.microsoft.com/en-us/windows/win32/api/winuser/nf-winuser-messagebox

Tip: When writing out the hexadecimal numbers from the WINAPI documentation, remove the L at the end so it works in Lua.

Description

Takes an lclosure (Lua function) and returns a new cclosure (C function). This is commonly used when setting the metamethods of a Roblox userdata such as game.

Example

local oldf = hookfunction(getrawmetatable(game).__namecall,newcclosure(function(self,...) if getnamecallmethod() == "Kick" then return end return oldf(self,...)end))

queue_on_teleport

Documentation

void queue_on_teleport(<string> source)

Description

Adds a string of Lua code source to a queue which is used when you teleport to another game. When you teleport to another game, every string of Lua code in the queue is executed in order.

Example

queue_on_teleport("print('hi')")queue_on_teleport("print('hi again')")game:GetService('TeleportService'):Teleport(game.PlaceId) -- teleports to the same game-- After Teleport Output:-- hi-- hi again

Additional Notes

This function will not check for errors and if the script has an error, you will see the error message after teleporting in the Roblox console. If you want to put a big script in the queue, it’s best to place that script in the workspace folder and use readfile to give queue_on_teleport the file contents.

readfile

Documentation

string readfile(<string> filename)

Description

Returns the contents of filename from the workspace folder as a string.

Example

test.txt

Hi

Script

Additional Notes

Keep in mind that in order to make the hook argument a C closure, you should use newcclosure(f).

request

Note: This function was changed on April 2, 2020 to match Roblox’s HttpService:RequestAsync.

Documentation

table request(<table> options)

Description

Sends a request configured by the options table. A table is returned which gives you information about the response of the request. See RequestAsync on the Roblox Wiki to learn more about the options you can provide and the response table.

Example

local r = request({ Url = "https://pastebin.com/raw/MVrUGHk5", Method = "GET" }) print(r.StatusCode) --> 200 print(r.Body) --> Hi

Additional Notes

Keep in mind that the request will have the User-Agent header set to sentinel and the Sentinel-Fingerprint header because it’s used internally for the HWID whitelist.

getinfo

Documentation

table debug.getinfo(<function, int> f)

Description

Returns a table containing the following information about the function:

• source - The name of the script the function was defined in
• what - Where the function originates from (Lua or C/C++)
• func - The passed in function
• short_src - The name of the script in a format that can be used in error messages
• name - The name of the function
• nups - The number of upvalues in the function
  Although more information is given, that information is pointless since it has the same values for every function.

Example

local x = 10function test() print(x)endfor k,v in pairs(debug.getinfo(test)) do print(k,v)end-- source @-- what main-- func function: 0xADDR-- short_src-- name-- nups 1

Additional Notes

• source can be @ which indicates the Lua function was defined in Sentinel, =[C] which indicates the C function is from Sentinel or Roblox, or a path to a script instance which indicates the Lua function was defined in a in-game script.
• what can be main which indicates the function is a Lua function or C which indicates the function is a C function
• name can only be retrieved for functions inside an in-game script

Note: Only use this function to get the names of local functions in an in-game script. Better methods exist for getting the other information provided by this function.
