Creating a VR Game: What You Should Consider

Designing a virtual reality game isn’t extremely challenging, thanks to the new engines, technologies, and other tools that can make your job easier. Virtual reality games provide gamers with amazing virtual objects, allow gamers to enjoy the game in real-time, create a rich gaming experience, boost attention and retention, and provide a game that looks more appealing and engaging. 

However, having a basic knowledge of these tools will help you design and develop a popular game that everyone will enjoy.

Choosing the gaming engine is the first step that you need to think about. Both engines are rapidly growing in popularity, although Unity currently occupies 48% of the market share while Unreal stands at a value of 14%.

Unity 3D video is the best game engine that you can use to develop your VR game. Most VR developers favor Unity because it’s easy to use. It also offers a great library of tutorials that will walk you through the developing process for the best results.

Unreal is another engine that developers have previously used for 2D games and will be used to develop 3D games. It’s also free but provides an extra advantage because you don’t need to have programming experience to use it.

In addition to all the free features, both engines offer chargeable elements that work for more experienced users.

After picking the engine, you need to decide on the operating system that supports your game, either for Android or iOS users. Each operating program has some presets that you can include in the coding and programming stage.

How to Create a VR Game

After choosing the tools that will help you develop your VR game, it’s time to get started. The process of designing and incorporating virtual reality in gaming can be broken into several steps. The following example involves creating a game where the characters navigate the castle, using Unity 3D engine.

Setting Up the Scene

After downloading your engine, which is the first step in the development of VR games, you need to pick the assets folder in your GoogleVR Unity package and choose build settings. Most developers choose to delete directional light, so they can have more control over how the game will look.

The next step involves creating a new 3D object. Choose the normal floor map to add texture to your 3D plane and to help the light reflect off the floor to add more depth to your scene. After setting it up, copy and paste the plane.

Complete the Scene

The next step involves adding texture. The transform controls allow you to rotate the plane until it’s facing the right direction. Once you have achieved the desired results, you need to copy and paste.

Follow the same step by adding another 3D object and add a suitable texture. Copy and paste the next object and scatter it as much as you can around the scene.

Set Up the Navigation

After creating the scene, you need to consider how the characters will move around it. This is called a navigation mesh which allows your characters to move through certain spots of your map, but not through all of them.

You can do this by creating an empty game object from the drop-down hierarchy. Add all the planes and cubes to organize the scene.

Go to the window, and bake this window to create a blue area that covers all the walkable spots in the map. Wherever you add a character, it will only move through the walkable path through the navigation mesh towards its destination.

Add the Characters

Your engine has an asset store, where you pick your characters. This step requires some coding experience, as you need to adjust the characters’ animation. After renaming the animation in the assets folder, you need to find the walk animation and drag it into the animation slot.

If the purpose of the game is to kill this character, you need to add a capsule collider which indicates that you can kill a character with a headshot. After that, you need to add a new script to your characters.

Once you’re done, you can drag your edited character into a new assets folder and call it Resources. Copy and paste this character as much as you want to, and set it up anywhere in the scene.

To kill this character, you need to create a bullet by creating and scaling down a bullet. Drag the bullet into the Resources folder, then drag and expand a gun. Reposition your gun to the center, and drag it on top of the camera to make it a child.

Add Some Code

You need to add a script component to the camera. Android and iOS codes will be different, allowing you to play your games on multiple platforms.

Give It a Try

Your game is almost ready, so you can give it a try to see how things work. You can see the ray from the spawn point to detect if your gun is pointing towards the target. Click the spawn points and make any component value adjustments to save the changes.

Transform the Game to Your Phone

Your game should be working fine now, but you need to transform it to your phone. Plug your phone into the computer using a USB. For iOS users, you need to download xCode to create an Apple developer account. For Android users, you need to have USB debugging.

Your game should be working fine, and if you need any adjustments, you can go back to the first stage and edit your game.

Wrap Up

Developing a VR game can be your chance to achieve success in one of the most competitive markets. But you don’t have to do it on your own. At WeAR Studio, you will find real experts who are ready to help you study and fine-tune your idea until your game is ready to launch.
