From 3D to XR

This project is a fork of the Starter Kit 3D Platformer by Kenney.

Described below is the process used to turn the project from a 3D game to a XR game running on the Meta Quest:

Project configuration

• Start by opening the original Starter Kit 3D Platformer in the Godot Editor
• To improve performance on the Quest, we'll disable some of the project settings:
  • In the scene dock, click on the Environment node
  • In the inspector dock, under the WorldEnvironment section, click on the main-environment entry
    • Set the Tonemap to Linear
    • Click on SSAO and set Enabled to OFF
    • Click on Glow and set Enabled to OFF
  • Change the renderer to Compatibility
    • this can be done from the drop-down in the top right corner of the editor window
    • Or from the project settings
  • Save & restart as needed
• Run the project to validate that it runs as expected
  • The character can be controlled using keyboard keys
    • The four keyboard arrows (up, down, left, right) are used to control the camera
    • WASD are used to move the character
    • SPACE is used for jumps

Adding the XR components

• Using the Asset Library, add the Godot OpenXR Vendors plugin for Godot 4.3 to the project.
• After installing the plugin, navigate to the Project Settings and scroll down to the XR section
  • In the Shaders section, set Enabled to ON
  • In the OpenXR section
    • Set Enabled to ON
    • Set Reference Space to Local Floor
  • Click Save & Restart to apply the new settings.

Configuring the XR Scene

• In the scene dock, find the View node (under the Main node) and delete it
• Add a XROrigin3D node to the Main node
• Add a XRCamera3D node to the added XROrigin3D node
• In the spatial editor window, position the XROrigin3D node where you want the user to be when loading the scene
  • E.g: high above the scene looking down on the playable character
• Select the Player node
  • In the inspector dock, under the Components section, select the XROrigin3D node for the View field
• Attach a script to the XROrigin3D node, and configure it to set up the XR scene
  • Update the _ready() function as follow:

func _ready() -> void:
  var xr_interface = XRServer.find_interface("OpenXR")
  if xr_interface and xr_interface.initialize():
	# Enable XR on the viewport
	var viewport = get_viewport()
	viewport.use_xr = true

	# Disable vsync
	DisplayServer.window_set_vsync_mode(DisplayServer.VSYNC_DISABLED)

• Once the script is complete, click the Play button to run the XR scene
