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.

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. |
