Work in progress

A virtual input device manager - written in Rust.

Overview

Reroute input:

• Combine input from multiple gamepads, joysticks, throttles etc. to one virtual joystick.

Transform input:

• Create analog axes from buttons.
• Apply button- or axis-trim to existing axes.
• Create tempo or toggle buttons from momentary buttons.

Shift-modes:

• Assign multiple output rebinds to one input via shift-modes.

Requirements

Windows 10/11 64 bit only for now. Linux support is blocked by a missing vJoy alternative.

vJoy driver version 2.2.1.1 needs to be installed.

State

Rebind maps can be created one rebind at a time with the existing UI. Rebinds can be edited and saved/loaded to/from a custom location. Input is properly transformed and piped.

The existing set of rebind types is enough to setup a proper flight sim configuration, but the setup takes a while.

Todo

• Easier rebind setup with quick-configurations ('setup wizard').

• More rebind variants:

  • Split hat into 4/8 buttons.
  • Combine buttons to hats.
  • More axes merge options.
  • Split axis into +/- component.

• Documentation/Guide for the available rebinds.

• In-application console for logging.

Build

Either call one of the launch batchfiles from the workspace root or build and copy to output manually:

Debug build:

• cargo build
• Copy assets/ to target/debug
• Copy SDL2.dll to target/debug

Profiling build:

• cargo build --release --features "profile"
• Copy assets/ to target/release
• Copy SDL2.dll to target/release
• Start Tracy client and connect running instance to collect traces.

Dist build:

• cargo build --profile dist
• Copy assets/ to target/dist
• Copy SDL2.dll to target/dist

Technical infos

Input is read through SDL2 as generic joystick input.

Output is piped to vJoy through a Rust wrapper library.

The GUI of choice: egui.

Which is rendered via Vulkan through a custom wrapper: VKU.

Rebind maps are de-/serialized to TOML through the Serde framework.

Profiling is supported through Tracy.
