Engine Sim Bridge

C bridge layer for engine-sim, providing a stable C API for .NET P/Invoke integration and other language bindings.

Purpose

This repository contains the bridge layer that wraps the core engine-sim C++ library in a C API. This allows the simulation to be used from:

• .NET applications via P/Invoke
• Other languages with C FFI support
• CLI tools that prefer a C API

Architecture

• engine-sim-bridge (this repo): C bridge API
• engine-sim: Core C++ simulation library

Building

mkdir build && cd build
cmake ..
make

API

The bridge provides a C API defined in include/engine_sim_bridge.h. Key features:

• Zero-allocation render path
• Thread-safe for single-threaded audio callbacks
• 48kHz sample rate support
• Script loading support
• Real-time parameter control (throttle, RPM, load, etc.)
