The Workspace and parts

Every visible thing in a Roblox game — the ground you stand on, the walls, the obstacles — is made out of parts. Parts are the LEGO bricks of Roblox. A whole game is just a collection of parts.

#The Workspace is the game world

In the Explorer, the Workspace is the top folder, and it's special: everything inside it is part of the game world. Put a part in Workspace and players can see it. Put a script in Workspace and it runs.

When we say "the game world", in code we'll refer to it as workspace (lowercase). That connection — the folder named Workspace in your Explorer, and workspace in scripts — trips people up for weeks. They're the same thing.

#Make some parts

1. In the Explorer, click on Workspace to select it.
2. In the top toolbar, click the Part button (or press Shift + 1). Click once to enter build mode, then click anywhere in the 3D view to drop a part.
3. Drop a few parts. Drag them with the move tool (Shift + 2), resize with the scale tool (Shift + 3), spin with the rotate tool (Shift + 4).

These shortcut numbers are worth learning now — you'll use them constantly.

#Where is a part? The Position property

Click one of your parts and look at Position in Properties. You'll see three numbers:

Position   0, 5, 0

Those are X, Y, Z — left/right, up/down, forward/back. Every point in the 3D view has exactly one set of coordinates, and when scripts move things around, they change these numbers.

Change the Y number to 10 and press Enter. Your part teleported straight up. You just "wrote" a position — a script will do the same thing later, but with code.

#Size, color, and saving

While a part is selected:

• Size is another set of three numbers (width, height, depth). The Baseplate is huge; your new parts are small cubes.
• Color is a color picker. Give each of your parts a different color so you can tell them apart.

Even though places autosave to the cloud, press Ctrl + S (Cmd + S on Mac) a few times while you work. It saves to your actual account and takes a second.
