field kits · s&box libraries · install via library manager

Tech from shipped games,
dropped into your project.

The Field Kits are s&box libraries pulled straight out of games I actually shipped — vehicle physics first, more on the bench. Install one and the source lands in your project, readable and yours.

01

How libraries work

a
You get the source
Install via Library Manager and every file arrives as plain C# and scenes. Read it, step through it, learn from it.
b
Delete what you don't need
It's your code once it's installed. Strip parts, rename things, bend it to your game. No upstream lock-in.
c
Every kit is self-contained
s&box libraries can't depend on other libraries, so no kit chain-drags dependencies in. One install, one folder.

Vehicle Physics Kit

live kitv0.3.0

The raycast-wheel driving stack from Vehicle Prototyping, my released driving sandbox. The game is the living demo; this library is the product.

The live tuning lab open over the demo cars, dials mid-drive
a
Raycast wheels that stay planted
Stable at speed, no rigidbody circus. The same suspension math the released game ships with.
b
Cars as data
Every car is one CarDefinition: chassis, wheels, tires, drivetrain, brakes, assists. Change numbers, hotload, feel it.
c
Tune it while you drive
The demo ships a live tuning lab: grip, torque, suspension, brakes, tire compounds, and assists, all changing under you mid-drive. Press T and start dragging sliders.
d
Demo scene included
Install, open the bundled scene, press play: four low-poly cars on a kilometer of pad, brackets to hop between them. Zero art required.
e
Proven in a released game
Vehicle Prototyping on sbox.game literally runs on this library, so every fix players feel there ships here first.
# install via Library Manager
1. editor menu: view → library manager
2. search fieldguide.vehiclephysics
3. install: source lands in your Libraries folder

On the bench

Placement Kitnext up
Orbit camera, tweak panel, ghost placement, and coordinate export: place things in play mode, then paste the result into your scene code.
The RPG familycoming soon
Small libraries extracted from RPG Builder: the systems spine, tips, interaction, and low-poly terrain. Each installs on its own.
Session Hardening Kitcoming soon
Everything I learned making P2P joins survive real players: late join, host migration edges, the reconnect dance.
Day / Night + Weather Kitcoming soon
A sun that actually moves, sky blends, and weather moods for your world. Small, drop-in, and easy to rip apart.
