Auto Scrolling Part I

CODE

Assets -> AndroidVRWebview -> Scripts -> AndroidWebview.cs

一樣只寫出有修改的部分

void HandleGaze() {
    Vector3 position = Camera.main.ViewportToScreenPoint(new Vector3(0.5f, 0.5f, Camera.main.nearClipPlane));
    Ray cast = Camera.main.ScreenPointToRay (position);
    RaycastHit hit;
    if (Physics.Raycast (cast, out hit)) {
        Vector2 local = CalculatePositionFrom (hit);
        HandleTimedGazing (local);
        HandleAutoScrolling (local);
    }
}

/*中略*/

bool autoScrolling = false;
void HandleAutoScrolling (Vector2 local) {
    if(local.y > websiteHeight * 0.875)        // scroll down
        StartCoroutine (Scroll (-5));

    else if(local.y < websiteHeight * 0.125)        // scroll up
        StartCoroutine (Scroll (5));

    else
        isScrolling = false;
}    

IEnumerator Scroll (int dir) {
    if(!autoScrolling) {
        autoScrolling = true;
        float x = websiteWidth / 2, y = websiteHeight / 2;
        SendEvent (new Vector2(x, y), ActionEvent.Down);
        for(int i = 0; i < 10; i++) {
            SendEvent (new Vector2(x, y += dir), ActionEvent.Move);
            yield return new WaitForEndOfFrame ();
        }
        SendEvent (new Vector2(x, y), ActionEvent.Up);
        autoScrolling = false;
    }
}
