Creating the course
For the first scene, add a Node3D node called Hole and save the scene. As you did in Jungle Jump, you’re going to make a generic scene containing all the nodes and code that any hole will need, then inherit from this scene to make as many individual holes as you want to have in the game.
Next, add a GridMap node to the scene.
Understanding GridMaps
GridMap is the 3D equivalent of the TileMap node you used earlier in the book. It allows you to use a collection of meshes (contained in a MeshLibrary collection – similar to TileSet) and lay them out in a grid. Because it operates in 3D, you can stack the meshes in any direction, although for this project you’ll stick to one plane.
Making a MeshLibrary collection
In the res://assets/ folder, you’ll find a pre-generated MeshLibrary feature named golf_tiles.tres containing all the necessary course parts along with their collision shapes.
