Gain insights into VR development with Unity and Meta Quest 2. Master lighting, physics, scripting, and create immersive experiences like Medieval Dungeon Escape, addressing the VR developer shortage.

Virtual reality has profoundly impacted many aspects of modern life, from global communication and financial transactions to immersive entertainment. Developing immersive 3D virtual worlds requires a deep understanding of technology, design principles, and programming.

Unity is the platform of choice for VR development, and this course provides a comprehensive understanding of its features and setup to support development for Meta Quest 2. You will first develop an understanding of basic concepts like lighting, physics, and animation, before grappling with advanced development topics like designing an interaction framework, scripting, and locomotion.  

By the end of the course, you will utilize your knowledge to build a VR game, i.e., Medieval Dungeon Escape. There is an acute shortage of VR developers worldwide, and this course presents a unique opportunity to advance your conceptual understanding of immersive technologies and get hands-on VR development experience.

Mastering VR Development with Unity and Meta Quest 2

```C#
using UnityEngine;

public class MagicScript : MonoBehaviour
{
    public Vector3 MagicIntensity;
    public GameObject[] MagicList;
    public bool MagicOn;
}
```

```C#
using UnityEngine;

public class MagicScript : MonoBehaviour
{
    private bool MagicOn;
    private GameObject[] MagicList;
    private Vector3 MagicIntensity;
}
```

```C#
using UnityEngine;

public class MagicScript : MonoBehaviour
{
    [SerializeField]
    private bool MagicOn;
    public GameObject[] MagicList;
    public Vector3 MagicIntensity;
}
```

```C#
using UnityEngine;

public class MagicScript : MonoBehaviour
{
    [SerializeField]
    private Vector3 MagicIntensity;
    [SerializeField]
    private GameObject[] MagicList;
    [SerializeField]
    private bool MagicOn;
}
```

```C#
using UnityEngine;

Both `ScriptB` and `ScriptC` are not attached to the cube.

Both `ScriptA` and `ScriptB` are attached but not enabled.

While `ScriptB` is not attached, `ScriptC` is attached but not enabled.

Both `ScriptA` and `ScriptB` are not attached to the cube.

Both `ScriptB` and `ScriptC` are attached but not enabled.

While `ScriptA` is not attached, `ScriptB` is attached but not enabled.

**(Select all that apply.)** We have written the following three scripts for a cube below:
### Script A
```C#
using UnityEngine;
public class ScriptA : MonoBehaviour
{
  void Awake()
  {
    transform.localScale = new Vector3(
      transform.localScale.x * 0.5f,
      transform.localScale.y * 0.5f,
      transform.localScale.z * 0.5f);
  }
}
```
### Script B
```C#
using UnityEngine;
public class ScriptB : MonoBehaviour
{
  void Start()
  {
    transform.Translate(new Vector3(2f, 2f, 0f));
  }
}
```
### Script C
```C#
using UnityEngine;
public class ScriptC : MonoBehaviour
{
  void FixedUpdate()
  {
    transform.Rotate(0, 0, -45 * Time.deltaTime);
  }
}
```
Based on the animation below, only one of the scripts works. What could be the possible reasons for this?
