driVR 2.0

VR driving/interaction application built with Godot 4.6 targeting Meta Quest via OpenXR.

Project Setup

• Engine: Godot 4.6 (GL Compatibility renderer)
• Main scene: res://main.tscn
• XR: OpenXR enabled; uses Jolt Physics at 90 ticks/second
• Renderer: GL Compatibility (D3D12 on Windows, GL on mobile)
• Key features: Road generation, VR hand interaction, traffic simulation, procedural road generation

Core Dependencies

• godot-xr-tools (v4.4.1-dev) – VR toolkit with hand interactions, pickup, teleport, movement providers
• godot-meta-toolkit – Meta GDExtension for Quest
• godotopenxrvendors – OpenXR loaders (Meta, Pico, etc.)
• road-generator (v0.9.0) – Procedural highway/intersection mesh generation

Export to Meta Quest

This repo already includes an Android export preset named Meta Quest.

For a first-time setup:

1. Install Godot 4.6 with Android export templates.

2. Install the Android SDK and a Java JDK, then point Godot to them in Editor Settings → Export → Android.

3. Open this project in Godot and make sure it loads without missing dependencies.

4. Confirm the Android package name is suitable for your device/builds.

   Current value: com.einar.driVR

5. Configure signing in Godot.

   • For local testing, a debug keystore is enough.
   • For distribution, use your own release keystore.

6. In Project → Export, select Meta Quest and export an APK for headset testing.

Project-specific export details:

• Target architecture: arm64-v8a
• XR mode: enabled
• Meta plugin: enabled
• Quest support: Quest 2, Quest 3, and Quest Pro
• Optional Meta features already enabled in the preset: eye tracking, face tracking, body tracking, hand tracking, passthrough, render model

If export fails, the usual culprits are missing Android templates, incorrect SDK/JDK paths, or signing not being configured.

Deploy over USB (recommended first run)

Use USB for the first install and for the least fiddly workflow.

• Enable Developer Mode for your Quest headset in the Meta mobile app.
• Connect the headset to your PC with USB-C.
• Put on the headset and accept the USB debugging prompt.
• Verify connection:
  • adb devices

When the headset appears in the device list, export or deploy using the Meta Quest preset.

Wireless deploy

You can deploy wirelessly after one-time USB debugging authorization.

• Complete the USB setup above at least once.
• Switch ADB to TCP mode, then connect over Wi-Fi:
  • adb tcpip 5555
  • adb connect <QUEST_IP>:5555
• Verify wireless connection:
  • adb devices

You can then deploy from Godot without a cable, as long as the PC and headset are on the same network.

Android logging (adb logcat variants)

Common options for different log output formats:

• Godot-only logs (quiet everything else):
  • adb logcat -s godot:V Godot:V *:S
• Godot-only logs with timestamps:
  • adb logcat -v time -s godot:V Godot:V *:S
• Godot-only logs with thread/process details:
  • adb logcat -v threadtime -s godot:V Godot:V *:S
• Warning/error logs from all tags, but keep Godot verbose:
  • adb logcat *:W godot:V Godot:V
• Full device logs (all tags):
  • adb logcat
• Crash buffer only:
  • adb logcat -b crash
• Dump current logs once and exit (good for sharing):
  • adb logcat -d
• Clear log buffers:
  • adb logcat -c
