Setting up the scene

To begin our exploration of input mechanisms, let's set up our scene. The plan is to let players create balloons. Everyone loves balloons!

For this scene, you could start with a new scene (File|New Scene) and then add an XR Rig from the GameObject | XR menu. Instead, I've decided to start with the Diorama scene used in the previous chapter and remove all but the GroundPlane and PhotoPlane, as follows:

1. Open the Diorama scene.
2. Remove all the objects, except for XR Rig, XR Interaction Manager, Directional Light, GroundPlane and PhotoPlane.
3. Position the XR Riga few feet from the scene origin, Position (0, 0, -1).
4. Select File | Save Scene As and give it a name, such as Balloons.

Now that the scene stage is set, we are first going to define a balloon game object, make it a prefab, and add an empty controller object in the hierarchy and script that will instantiate the balloon prefab...
