To start recreating the Island Jump 3D platformer game, you need a project to build in. A project is a collection of places, assets, and settings that together make up a Roblox game.
The fastest way to start is to use a Studio template. For this project, you'll use the default Baseplate template, which has a flat ground and a SpawnLocation object.
- In Roblox Studio, click New Experience in the upper-left corner.
- In the Explorer window, expand Workspace and delete the Baseplate object so that the viewport shows an empty world with just the spawn location in the middle.

In the next section, you'll learn how to use the Terrain Editor to create an island environment around the spawn location.
