Let's Get Ready to Move

Please Note the Following

  • After reviewing the course, we have decided it is easier to simply replace the code in the original GameLogic.cs with a copy/paste instead of downloading a new file. Please replace the code in your existing GameLogic.cs script with the updated code provided below.
  • The GvrViewerMain prefab you see in the Hierarchy during the videos no longer exist in GoogleVR Unity SDK and is now represented by the GvrEditorEmulator prefab.
  • The Main Camera you see in the Hierarchy during the videos will typically be nested as a child of the GvrEditorEmulator prefab.
  • The GvrReticle prefab you see in the Hierarchy during the videos has been renamed GvrReticlePointer.
  • The GazeInputModule script no longer exist in GoogleVR Unity SDK and we recommend using the GvrEventSystem prefab instead of the default Unity EventSystem because this prefab already has the required script components.
  • The stereoscopic view you see in the video while in Game mode is no longer rendered in the Unity Game view due to changes to GoogleVR Unity SDK. However, you can still use Alt + Move Mouse to simulate head rotation and Ctrl + Move Mouse to simulate head tilt.
  • If you find that Alt + Move Mouse and Ctrl + Move Mouse does not respond once you have entered Game mode, it's most likely because the Unity project is using GoogleVR Unity SDK version 1.6. For this versions of GoogleVR Unity SDK the head rotation and tilt simulation does not work while using Unity desktop platform mode. Therefore, you need to use a mobile platform, by going to File > Build Settings... and switching to either iOS or Android platform in the Build Settings popup window.
  • In general, the camera should be nested under a parent gameobject, for example, the GvrEditorEmulator prefab, and have a local position and rotation of 0, 0, 0. To reposition the camera, the parent gameobject should be repositioned and the camera itself should keep its local position and rotation of 0, 0, 0.

Updated GameLogic.cs script

using UnityEngine;
using System.Collections;

public class GameLogic : MonoBehaviour
{
    public GameObject player;
    public GameObject startUI, restartUI;
    public GameObject startPoint, playPoint, restartPoint;

    void Start()
    {
        // Update 'player' to be the camera's parent gameobject, i.e. GvrEditorEmulator, instead of the camera itself.
        // Required because GVR resets camera position to 0, 0, 0.
        player = player.transform.parent.gameObject;

        // Move player to the start position.
        player.transform.position = startPoint.transform.position;
    }

    void Update()
    {
        if (Input.GetMouseButtonDown(0) && player.transform.position == playPoint.transform.position)
        {
            PuzzleSuccess();
        }
    }

    // Begin the puzzle sequence.
    public void StartPuzzle()
    {
        ToggleUI();
        iTween.MoveTo(player,
            iTween.Hash(
                "position", playPoint.transform.position,
                "time", 2,
                "easetype", "linear"
            )
        );
    }

    // Reset the puzzle sequence.
    public void ResetPuzzle()
    {
        player.transform.position = startPoint.transform.position;
        ToggleUI();
    }

    // Do this when the player solves the puzzle.
    public void PuzzleSuccess()
    {
        iTween.MoveTo(player,
            iTween.Hash(
                "position", restartPoint.transform.position,
                "time", 2,
                "easetype", "linear"
            )
        );
    }

    public void ToggleUI()
    {
        startUI.SetActive(!startUI.activeSelf);
        restartUI.SetActive(!restartUI.activeSelf);
    }

    // Placeholder method to prevent compiler errors caused by this method being called from LightUp.cs.
    public void PlayerSelection(GameObject sphere)
    {
        // Will be completed later in the course.
    }
}
