# First-Person 3D Starter V0 Template — React Three Fiber Game: Deploy First, Preview Second

- Tool: V0 Templates
- Last updated: July 2026

## TL;DR

The First-Person Starter is a V0 community template that gives you a working browser-based 3D scene with first-person WASD movement and mouse-look — built on React Three Fiber, @react-three/drei, and Three.js. It includes pointer lock controls, basic scene geometry, ambient lighting, and a 2D HUD overlay. Best for developers building 3D game prototypes, interactive product showcases, or learning react-three-fiber. Critical caveat: deploy to Vercel immediately — Three.js doesn't load reliably in V0's preview sandbox.

## Frequently asked questions

### Is this template free?

Yes. It's a free V0 community template — forking is free. AI chat edits after forking consume V0 credits.

### Can I use this template commercially?

Yes. The code stack (@react-three/fiber MIT, @react-three/drei MIT, Three.js MIT, Next.js MIT) is fully permissively licensed. Any 3D assets you add need to be licensed appropriately for your use case.

### Why does my fork show a blank screen or loading error in V0 preview?

This is expected. Three.js and @react-three/fiber are too large for V0's esm.sh preview sandbox to reliably resolve. The fix is to deploy immediately via Share → Publish → Publish to Production, then test on the Vercel URL. Don't evaluate this template's quality based on the preview.

### Why doesn't pointer lock work in the V0 preview tab?

The Pointer Lock API requires HTTPS and a proper user gesture. V0's preview is an iframe without a qualifying secure context, so PointerLockControls silently fails. Deploy to Vercel — the .vercel.app URL is HTTPS and pointer lock works correctly there.

### How do I connect a database to this template?

The template is a pure client-side 3D scene with no database. The most common addition is a Supabase leaderboard or player position sync. Add NEXT_PUBLIC_SUPABASE_URL and NEXT_PUBLIC_SUPABASE_ANON_KEY to the V0 Vars panel, then use Server Actions for DB writes. The advanced Supabase multiplayer prompt on this page shows the full pattern.

### Does this work on mobile?

No. Pointer lock doesn't work on mobile browsers — it's a desktop-only API. To support mobile, you'd need to replace PointerLockControls with a virtual joystick on the HUD overlay and touch-based camera rotation. That's a medium-complexity extension, not included in the starter.

### Can RapidDev help extend this 3D template?

Yes. RapidDev extends V0 3D starters into production-grade interactive experiences — adding GLTF asset pipelines, Rapier physics, mobile touch controls, and performance optimization for real user traffic.

### How do I add physics to the scene?

Install @react-three/rapier and wrap the scene in its Physics component. Add RigidBody and CuboidCollider to the GroundPlane with type='fixed'. The gotcha prompt about Rapier bodies falling through the ground (in the third-person-starter template) covers the exact setup — the pattern is identical here.
