Gyroscope

Description

Интерфейс для работы с гироскопом.

Use this class to access the gyroscope. The example script below shows how the Gyroscope class can be used to view the orientation in space of the iOS device.

// iOS gyroscope example
//
// Create a cube with camera vector names on the faces.
// Allow the iPhone to show named faces as it is oriented.

using UnityEngine;
using UnityEngine.iOS;

public class ExampleScript : MonoBehaviour
{
    // Faces for 6 sides of the cube
    private GameObject[] quads = new GameObject[6];

    // Textures for each quad, should be +X, +Y etc
    // with appropriate colors, red, green, blue, etc
    public Texture[] labels;

        // make camera solid colour and based at the origin
