Roblox Cheat Sheet Cheat Sheet (DRAFT) by

Roblox Cheat Sheet for Beginners

This is a draft cheat sheet. It is a work in progress and is not finished yet.

Home Tab

The Home tab is where we make and edit Parts.
Expanding the Part button shows other Part types.
To edit the Part, use these buttons: Select, Move, Scale and Rotate.
The Play button can be used to run the game.

View Tab

The View tab contains all the windows in Roblox Studio. We will mostly be using Explorer, Properties, Output and Toolbox.

Explorer Window

The Explorer Window shows the location of your objects in the game. Each Service has its own use. For example, objects located in Workspace will be rendered in the 3D space and Players contains all the player clients that join the game.

Explorer

game
Parent of everything in Explorer
Workspace
Used to hold objects that will be rendered in the 3D space
Players
List of all Player Clients that join the game
Replic­ate­dFirst
Replicates all objects under this tab to all the Clients (and not the server)
Replic­ate­dSt­orage
Storage available to Clients and Server
Server­Scr­ipt­Service
Storage for Module­Scripts and Server­Scripts
Server­Storage
Storage available only to the Server
StarterGUI
Used to hold GUI objects that will be copied to all clients
Starte­rPack
Used to hold items that are then copied into the Player's backpack
Starte­rPl­aye­rSc­ripts
Used to store LocalS­cripts for the Player
Starte­rCh­ara­cte­rSc­ripts
Used to store LocalS­cripts for the Player's character

Properties Window

The Properties Window shows the proper­tie­s/a­ttr­ibutes available to the object. Select an object to show its proper­ties.

Toolbox

There are a lot of resources available in the Toolbox like Models, Images, Audio, etc.
  

Objects

Part
A physical brick in the world
Model
A container for Parts
Script
A container for Lua source code that is run on the Server
LocalS­cript
A container for Lua source code that is run on a Client

Variables

myNumber = 17
myName = "Cathy"

print("My name is ", myName, "and I'm ", myNumber)
Variables can be used to store anything from numbers, strings and other objects. You do not need to specify the type of variable (i.e. int, String, bool).

Refere­ncing Objects

-- create a variable for a Part located in the Workspace
part = game.Workspace.Part

*--[[
create a variable for a Script in StarterPlayerScripts 
          (Which is located in StarterPlayer)*
]]*
script = game.StarterPlayer.StarterPlayerScripts
To reference an object, use a period to go through the hierarchy (Parent to Child). Refere­ncing is similar to finding a pathway to the object.

Models

Models are Parts that are grouped together. It makes it easier to move objects that consists of a lot of objects like a Tree (which can have Trunk Parts, Leaf Parts, etc).

Part Properties

-- declare a variable for the Part
part = game.Workspace.Part

-- changes the Part's name (Name shown in Workspace)
part.Name = "New Part Name"

-- changes the Part's BrickColor to Colour Name
part.BrickColor = BrickColor.new("Colour Name")

-- change the position using the x, y, and z coordinates
part.Position = Vector3.new(x, y, z)

-- change the size using x, y, and z coordinates
part.Size = Vector3.new(x, y, z)

-- anchors the Part so it cannot be moved around
part.Anchored = true
Here are some common properties used for Parts

Creating an Object

newObject = Instance.new("Part")
--create a new object, Part, called newObject

newObject.Name = "myObject"
--assigns a name to the new object

newObject.Parent = game.Workspace
--assigns a Parent to the object

secondObject = newObject:Clone()
--clones the original object

newObject:Destroy()
--destroys the object
Here's some general code on how to create a new object.

Parent vs Child

A child is an object that is under a Parent (another object). In this image, the LocalS­cript is a Child of Starte­rCh­ara­cte­rSc­ripts. Easiest way to tell if something has a child is to see if you can expand it (arrow to the left side). Anything that comes up after you expand something is the child of that object.
  

Operators

==
Equals to
~=
Not Equal
>
Greater than
<
Less than
>=
Greater than or equal to
<=
Less than or equal to
 
+
Add
-
Subtract
*
Multip­lic­ation
/
Division
^
Expone­nti­ation
%
Modulus

Function

wait(10)
Waits for 10 seconds
 
print(­"­Hello World!­")
Prints the message in the Output window

Custom Functions

-- this function adds 2 numbers
function sum(num1, num2)
     print(num1 + num2)
end

sum(1, 2)

-- assigns a variable to the result of the function
function calculateSquare(n)
     return n * n
end

result = calculateSquare(3)

Condit­ional Statements

if workspace:FindFirstChild("Tree") then
     print("There is a tree here.")
end


if coins < 5 then
     print("You need more money.")
else
     print("You have enough money!")
end


if player.Name == "Jake" then
     print("You are an awesome guy, Jake")
elseif player.Name == "Sally" then
     print("You are a sweetheart, Sally")
else
     print("You are a pretty cool person")
end
If statements will run their code if the value between if/then is true (or not nil). They can one an else block, or any number of elseif blocks.

Loops

i = 0
while i < 10 do
     i += 1
end
--while loop, adds 1 to i until i is greater than 10

while true do
     print("while loop")
     wait(1)
end
--while loop, infinite loop since it is always true


for i = 1, 10 do
     print(i)
end
--for loop, prints i until i reaches 10

for i = 0, 10, 2 do
     print(i)
end
--for loop, prints i until i reaches 10 (i adds 2 each time)

Player vs Character vs Humanoid

Player
The Player's Client, stores inform­ation relating to the player's account (UserID, SpawnL­oca­tion, etc)
Character
The Player's physical character in the 3D world. It is a model and contains all the Player's body parts (Human­oid­Roo­tPart, Head, etc))
Humanoid
A child of the Player's character. Includes properties such as Health, JumpHe­ight, WalkSpeed, etc.
