Virtual Reality (VR) is one of the modern technologies which provides us with the most exciting experiences. This advanced technology has undoubtedly proved to be boon for the business as it helps them to create an impressive presence among the targeted users in a shorter time span than their imagination. According to the report augmented and virtual reality (AR and VR) market is expected to reach around 18.8 billion U.S. dollars by the end of 2020, this number is expected to jump higher during upcoming years.

Consumer spending on AR and VR products is also increasing with the passage of time. After exploring this number, it’s not wrong to say that AR and VR will create a buzz in the market in the near future and those who don’t opt for this advanced technology will definitely be left behind from others. Many of the people are also learning to improve their basic VR development skills. They are opting for various online VR courses, which can help them to learn to create a VR game and many other VR based projects.

Know Why You Must Create a Game With VR?

There are many questions which might buzz in any of the individual’s mind when it comes to developing the VR based game, the very first and most important question which arises in any of the individual minds is whether their game will be relevant in VR? Whether this game will provide the same 3D experience.

Explore Few Simple Steps Which Can Guide You to Craft Your First VR Game

One of the Developing VR games is to provide an impressive experience to the gamers whenever they explore the gaming platform. Some of the first-person games which are popular among gamers are Imagine Mirror’s edge, Call of Duty, and many others. While some of the third person games which are popular among the gamers are Splinter Cell, Gears of War, Assassin’s Creed, and many others.

Nowadays, more and more gamers prefer to play VR based games as they feel that VR games are great and provide them with the best experience than ever before. Hence if you want to learn to code, then it will be advisable for you to explore numerous steps provided below to know how you can develop VR based games in a short duration of time.

Step1: Set the Screen

Before starting the development task, make sure that you install with complete Android or iOS modules that you need for developing your VR based game such as VR Shooters. Once you complete the installation task, make sure that you create a new Unity project by doing, so it becomes easy for you to call it whatever you want.

Once after creating the Unity project, drag the GoogleVR Unity package within the game assets folder. Now add a gun 3d model into the same folder. Go to build setting options available in the file and then switch the platform to iOS or Android. Go to the and create a 3d plane and object. Once after completing all the screen settings, you can move ahead to the next step.

Step2: Bake Navigation Mesh

After setting up the screen, you need to add zombies, but before that, you have to consider deciding the navigation for the same.  You need to bake the navigation to decide how your zombies will move around and act in the game which you are developing. Developers can use Unity to find the path that zombies can use to bake navigation to know through which areas are safe to move and which are not.

Developers need to go to the hierarchy to build an empty game object. Then they can rename all the scenes and can also drag all their cubes and planes on top, this can help them to make the child class of the parent class, which they have developed before. Now go to the navigation window and click on it, you can see the blue area in your screen, this is the navigation mesh where you have to navigate your zombies as navmesh agents. This will allow your zombies to move successfully in the areas which you have decided.

Step3: Create a Code

Now it’s a time when you need to develop the code for your VR based game, you need to develop a Zombiescript.cs file. It is just the same as developing the code for an online ordering system that you develop using the virtual reality (VR) technology. If you have basic developing knowledge, then it becomes quite easy for you to code your VR based application, you can even reuse some of the code to develop your gaming app.

Code to Use for Make Your Zombies Work Efficiently:

using UnityEngine;

using System. Collections;

public class ZombieScript : MonoBehaviour {

private Transform goal;

private NavMeshAgent agent;

// Now use it for initialization

void Start () {

//create references

goal = Camera.main.transform;

agent = GetComponent();

//set the nav mesh agent’s designation equal to the main camera’s position (our first person character)

agent1.destination = goal.position;

//start here with the animation of walking

GetComponent().Play (“walk”);

}

//here this to work both need colliders, one must have a rigid body, and the zombie must have its trigger checked.

void OnTriggerEnter (Collider col)

{

GetComponent().enabled = false;

//destroy the bullet

Destroy(col.gameObject);

//stop the zombie from going forward by setting its destination to it’s right position

agent.destination = gameObject.transform.position;

//now stop the animation from walking and play it with the animation which is falling back

GetComponent().Stop ();

GetComponent().Play (“back_fall”);

Destroy (gameObject, 6);

GameObject zombie = Instantiate1(Resources.Load (“zombie”, typeof(GameObject))) set as GameObject;

float randomX = UnityEngine.Random.Range (-13f,12f);

float constantY = .01f;

float randomZ = UnityEngine.Random.Range (-12f,12f);

zombie.transform.position = new Vector3 (randomX, constantY, randomZ);

while (Vector3.Distance (zombie.transform.position, Camera.main.transform.position) <= 3) {

randomX = UnityEngine.Random.Range (-12f,12f);

randomZ = UnityEngine.Random.Range (-13f,13f);

zombie.transform.position = new Vector3 (randomX, constantY, randomZ);

}

}

}

Now create the code for your camera by giving it the name playerScript.cs.

Code for the Use of the Camera:
private GameObject gun;
private GameObject spawn point;
private bool isShooting;

// Use this for initialization
void Start () {

//only needed for IOS
Application.targetFrameRate = 60;

//create references to gun and bullet spawnPoint objects
gun = gameObject.transform.GetChild (0).gameObject;
spawnPoint = gun.transform.GetChild (0).gameObject;

//set isShooting bool to default of false
isShooting = false;
}

//Shoot function is IEnumerator so we can delay for seconds
IEnumerator Shoot() {
//set is shooting to true so we can’t shoot continuously
isShooting = true;
// take the instantiation for the bullet
GameObject bullet = Instantiate(Resources.Load(“bullet”, typeof(GameObject))) as GameObject;
//Get the bullet’s rigid body component and set its position and rotation equal to that of the spawnPoint
Rigidbody rb = bullet.GetComponent<Rigidbody>();
bullet.transform.rotation = spawnPoint.transform.rotation;
bullet.transform.position = spawnPoint.transform.position;
rb.AddForce(spawnPoint.transform.forward * 500f);
GetComponent<AudioSource>().Play ();
gun.GetComponent<Animation>().Play ();
Destroy (bullet, 1);
yield return new WaitForSeconds (1f);
isShooting = false;
}

// Update is called once per frame
void Update () {

//declare a new RayCastHit
RaycastHit hit;
//draw the ray for debugging purposes (will only show up in scene view)
Debug.DrawRay(spawnPoint.transform.position, spawnPoint.transform.forward, Color.green);

//cast a ray from the spawn point in the direction of its forward vector
if (Physics.Raycast(spawnPoint.transform.position, spawnPoint.transform.forward, out hit, 100)){

//if the Raycast hits any game object where its name contains “zombie” and we aren’t already shooting we will start the shooting coroutine
if (hit.collider.name.Contains(“Shooting Object”)) {
if (!isShooting) {
StartCoroutine (“Shoot”);
}

}

Step4: Transfer the Game to Your Phone

Once after finishing up with the coding process, it’s time to transfer your VR based game to your smartphone. Make the needed changes required to transfer the game from desktop to phone and run it to find whether you have developed it perfectly or not. If you have developed it perfectly then, it will definitely run successfully on any of the platforms you desire.

Ending Note

There are a lot more things to learn when it comes to VR development. Virtual reality has much to offer to the developers as well as to learners. Any of the individuals who want to learn developing VR games in detail explore some of the eLearning courses available online. They can even take the guidance of the experts and developers from different sources available online.
