使用するときは適当なGameObjectにこのScriptをアタッチして

using UnityEngine;

public class TouchEventTest : MonoBehaviour {
    void Start () {
        GearVRHelper.OnBackHold += () => {
            Debug.Log("BACK HOLD!");
        };
        GearVRHelper.OnBackPush += () => {
            Debug.Log("BACK PUSH!");
        };
        GearVRHelper.OnTap += () => {
            Debug.Log("Tap!");
        };
        GearVRHelper.OnFlick += (x, y) => {
            Debug.Log("Flick:" + x + "," + y);
        };
        GearVRHelper.OnDrag += (x, y) => {
            Debug.Log("Drag:" + x + "," + y);
        };
    }
}

のようにStatic領域のeventに追加。

注意

eventをStaticにした関係上Awakeにeventのクリア処理が入っており、Awakeでイベント追加しても順番的に消されてしまうかもしれないので、Startでの追加推奨。
