About vJoy

vJoy simulates up to 16 input devices with up to 128 buttons, 8 axes, and 4 hat switches (4-way or continuous). The virtual devices can be used to

1. Emulate gamepads/joysticks for older games that require a specific kind of input.
2. Combine multiple physical devices into one virtual.
3. Apply transformations from a physical device to a virtual device (e.g. 2-button to axis rebind, software filtering etc.).

The virtual devices appear to applications as regular input devices.

Usage

The vJoy driver version 2.1.9.1 needs to be installed and is only available for Windows.

The vJoy shared library is loaded at runtime via libloading. See the integration tests for specifics.

Example

use vjoy::{VJoy, ButtonState, Error, HatState, FourWayHat};

fn main() -> Result<(), Error>{
    let mut vjoy = VJoy::from_default_dll_location()?;
    let device_1 = vjoy.get_device_state_mut(1)?;

    device_1.set_button(1, ButtonState::Pressed)?;
    device_1.set_axis(1, i32::MAX)?;

    let hat_type = device_1.hat_type();
    let value = match hat_type{
        HatState::Discrete(_) => HatState::Discrete(FourWayHat::East),
        HatState::Continuous(_) => HatState::Continuous(90 * 100),
    };
    device_1.set_hat(1, value)?;

    vjoy.update_all_devices()?;

    Ok(())
