What is it?

This is a rust library that allows you to interface with your Oculus Touch controllers and headset. It is a wrapper for the auto_oculus_touch project.

With it, you can read the current state of the controllers and headset, send button presses to the controller, or move the thumbsticks.

Installation

cargo add rust_oculus_touch

Example Usage

Below is a short program that will vibrate both controllers for 1 second whenever the X button is pressed while the headset is being worn.

use rust_oculus_touch as ot;

fn main() {
    let oculus = ot::OculusTouch::new();
    oculus.InitOculus();

    while true {
        oculus.Poll();
        println!("\n");

        let wearing = oculus.Wearing();
        println!(
            "Headset is {} your head",
            if wearing { "ON" } else { "OFF" }
        );

        let x = oculus.GetPositionX(ot::OculusTouchControllerEnum::Head);
        let y = oculus.GetPositionY(ot::OculusTouchControllerEnum::Head);
        let z = oculus.GetPositionZ(ot::OculusTouchControllerEnum::Head);
        let yaw = oculus.GetYaw(ot::OculusTouchControllerEnum::Head);
        let pitch = oculus.GetPitch(ot::OculusTouchControllerEnum::Head);
        let roll = oculus.GetRoll(ot::OculusTouchControllerEnum::Head);
        println!(
            "Headset Position: ({}, {}, {}), Yaw: {}, Pitch: {}, Roll: {}",
            x, y, z, yaw, pitch, roll
        );

        let buttons_down = oculus.GetButtonsDownList(); // Get a list of buttons that are currently held down
        let sensors_touched = oculus.GetTouchDownList(); // Get a list of capacitive sensors that are currently being touched
        println!("These buttons are down: {:?}", buttons_down);
        println!("These sensors are touched: {:?}", sensors_touched);

        println!("Here's a vibration for fun!"); // Vibrate the controllers
        oculus.Vibrate(
            ot::OculusTouchControllerEnum::Left,
            ot::OculusTouchVibrationFrequencyEnum::Medium,
            128,
            1.0,
        );
        oculus.Vibrate(
            ot::OculusTouchControllerEnum::Right,
            ot::OculusTouchVibrationFrequencyEnum::Medium,
            128,
            1.0,
        );

        oculus.PollAndSleep(1.0 as u64); // Poll and wait 1 second
    }
}

This is a smaple output from the above program:
