Car Testing

An experimental vehicle controller built entirely in Hypixel Housing with HTSW.

The project turns normal player movement into a small driving system with acceleration, braking, steering, drifting, ramps, crash feedback, rendered wheels, and an in-game HUD. It is also a practical experiment in building real-time movement and physics-like behavior within Housing's action system.

Features

• Speed-sensitive acceleration, drag, and engine braking
• View-directed steering with separate forward and lateral velocity
• Grip, drift entry, drift recovery, and braking behavior
• Ramp and airborne handling
• Collision detection with rebound and crash feedback
• Four-wheel visualization using dropped items
• HUD indicators for throttle, steering, grip, braking, speed, and crashes
• Debug readout for tuning the controller in game

Controls

The import includes two custom items:

Item	Action
Toggle Car	Right-click to enable or disable the vehicle controller
Car Controls	Right-click to accelerate; left-click repeatedly to brake

Look where you want to steer while the controller is enabled.

How it works

Runner is a repeating Housing function that advances the simulation in several smaller steps. Each update calculates the player's desired heading, applies throttle and braking, separates forward movement from sideways slip, updates traction or drifting, detects ramps and collisions, and finally writes the result back through player velocity.

Housing variables hold the vehicle's state between updates. The constants in functions/set_constants.htsl are the main tuning surface for acceleration, drag, grip, drift, ramp, and crash behavior.

Importing

1. Install HTSW and its in-game module.

2. Clone this repository into your HTSW projects directory.

3. Validate the project from this directory:

   htsw check import.json

4. In Minecraft, stand in the Housing plot where you want the system and import the root import.json through HTSW.

5. Use the imported Toggle Car and Car Controls items to drive.

This is an experimental Housing project, so it is best imported into a test house before being integrated into a larger game.
