Creating the course

For the first scene, add a node called Main to serve as your scene's root. This scene will contain the major parts of the game, starting with the course itself. Start by adding a GridMap node to lay out the course.

GridMaps

GridMap is the 3D equivalent of the TileMap node you used in earlier projects. It allows you to use a collection of meshes (contained in a MeshLibrary) and lay them out in a grid to more quickly design an environment. Because it is 3D, you can stack the meshes in any direction, although for this project, you'll stick to the same plane.

Making a MeshLibrary

The res://assets folder contains a pre-generated MeshLibrary for the project, containing all the necessary course parts along with collision shapes. However, if you need to change it or make your own, you'll find the procedure is very similar to how TileSet is created in 2D.

Note

The scene used to create the pre-generated MeshLibrary can also be found in the res://assets folder. Its name is course_tiles_edit1...
