What is Minecraft?

Minecraft is an action-adventure sandbox title created by Mojang way back in 2009 and purchased by Microsoft in 2014.. It offers players a limitless virtual world where they can build anything with an array of different modes. It is perfect for almost any type of gamer. Minecraft is available on almost any gaming platform: computers, Sony Playstation, Microsoft Xbox, Nintendo Switch, VR, mobile devices (pocket edition), tablets, and more.

Minecraft comes with lots of features, including crafting, gathering basic necessities, creating safety, and exploring. If you are a creative person, you will enjoy the endless playground the game has to offer. You can build virtually anything you can imagine. The team frequently releases new worlds, equipment, and modifications that keep the game fresh and exciting for players.

Along with Roblox and Fortnite, Minecraft is one of the most popular games of all time. The popularity of the game has led to online showcases of elaborate lands that have been built. Real world locations like San Francisco, New York, Paris, and other cities have been modeled in Minecraft for users to explore.

The game’s two main games are Creative and Survival Mode.

Survival Mode

In Survival Mode, players must find their own building supplies and food. They also interact with blocklike mobs or moving creatures.

Creative Mode

In Creative Mode, players are given supplies and do not have to eat to survive. They also can break all kinds of blocks immediately.

Minecraft VR

When the first virtual reality headsets were released, fans were quick to create a third-party hack that allowed Minecraft to be played in VR. This VR version hack is still available today and it is called Vivecraft.

Over time, Minecraft has added support for virtual reality to some select headsets. The Samsung Gear VR edition was the first to receive support and the Oculus Rift VR headset does today too. At one point, Oculus and Minecraft even partnered on a VR headset and controller bundle.

Today, the official VR version is one of the most popular and immersive VR games available. Virtual reality gives players a more immersive experience verses traditional PC gaming. If you have an Oculus Rift headset and own the PC version, VR Minecraft is available as a free update.

Minecraft gets even more advanced with ray tracing if you own one of the new Nvidia RTX 30-series graphics cards.

Next, we’ll go over the official Minecraft virtual reality version verses Vivecraft including their similarities and differences. This will help you decide which VR experience is best for you to install.

Minecraft VR vs Vivecraft

Virtual reality support has been added to Minecraft VR through a close partnership with Facebook and Oculus. Oculus headset owners can download the VR addon for free from the Oculus store. When they run it in their VR headset, Minecraft will launch with full VR support. When the Minecraft game is updated, Rift S owners have VR support immediately. There is no need to wait for a mod to catch up with the main game release.

This sounds great, but it’s a bit more complicated than that. For starters, there are actually two active versions of Minecraft: Windows edition and Java edition. Let’s go over those two first:

Windows vs Java Editions

Originally, Java was the original desktop version of Minecraft and the Windows edition was a port of the pocket edition. Over time, these two versions will merge together into a single copy. Until there, there are a few big diferences.

For starters, the Java edition allows you to play Minecraft multiplayer with people around the world. There are plenty of VR servers to join and play with other players. The Windows edition supports playing in a single room with up to 10 people at a time only.

If you want to play with Minecraft VR mods and enhancements then the Java edition is going to be your pick. The Windows edition does not currently support third party mods outside of a few texture enhancements.

The Windows Edition of Minecraft supports Xbox and other Bluetooth controllers better. You can configure your controller to work best for you and optimize to your liking. This might not be a big factor for virtual reality players, since VR mode activates VR controller support at the same time.

Lastly, the cost of the Java edition is higher at $28 vs $10. When you buy the Java edition then you also get a code to redeem and play the Windows edition too.

Both editions of Minecraft have free VR support included. However, there is also a third party VR mod for Minecraft called Vivecraft.

Vivecraft

Vivecraft is a third-party Minecraft APK mod that makes the game compatible with virtual reality. It’s compatible with all headsets including all HTC and Oculus devices. The official Minecraft virtual reality only works really good on the Oculus Rift. In order to use Vivecraft, you must install SteamVR on your computer.

Other cool Vivecraft features are:

  • Full roomscale support
  • World scaling: Scale your size in the world up or down. Play as an ant or a giant
  • Break blocks and fight by swinging your hands
  • Shoot your bow by drawing and aiming two-handed
  • Climb, swim, run, jump, sneak, eat, and row by actually doing the motion!
  • Feed animals, mount horses, and fill buckets just by touching!
  • Play with your friends and see each other’s VR movements. (even for 2d players!)
  • Multiple VR locomotion options:
    • Arc teleportation
    • Free-movement in the direction you are pointing the controller or your head.
    • Walkabout-style of rotation using 100% room-scale movement.
    • Seated play with walkabout-style of rotation in your look direction
    • Wall-scaling and leaping

Vivecraft is completely safe and is a great option for VR players to have.

Players are mixed on which one is better between official Minecraft vs Vivecraft for virtual reality. Regular Minecraft has motion sickness due to the artificial movement. Vivecraft in teleport mode greatly reduces motion sickness, so it should be a lot better.

Official Minecraft offers better performance because it maintains a solid 90 FPS at much higher view distances. On the other hand, a lot of players prefer the Vivecraft control scheme a lot better.

Ultimately, both are worth checking out if you have an Oculus device. Or else, go with Vivecraft today.

Virtual Reality, or VR, can take you directly into the universe of Minecraft. Minecraft is one of the most famous and most played games in the world, and it is presently accessible in VR. Almost 170 million copies of Minecraft are sold out. In this video game, you can construct and move around several worlds, explore, and fight with dangerous Mobs. Basically, you can do whatever you like in Minecraft. When you encounter the Mobs directly, the VR head-mounted device creates a pronounced feeling of fear. This scenario encompasses you completely in the virtual environment because of the realistic 3D visual and audio effects.

Minecraft is becoming more popular day by day because it is available in several editions for various platforms, including Oculus Rift, Windows Mixed Reality, PlayStation3, PlayStation 4, Xbox 360, Xbox One, mobile devices, and PC. The versions of Minecraft that you can play using your VR headset are shown below:

There are two versions of the game. One of the versions is Minecraft Starter Collection, worth $29.99 USD, and the other is Minecraft Master Collection, worth $49.99 USD. The game is available on mobile, as well.

Minecraft for Oculus Rift

There are two ways to download Minecraft for Oculus Rift. It can directly be downloaded from the Windows Store or the Oculus Store. The game can be downloaded using either of these methods. To download Minecraft from the Windows store, go to the Microsoft Windows Store and search for the Minecraft game. Download a copy of Minecraft, sign in to your Microsoft account, and install the application. You can also try the game free of cost before buying the full game.

The Demo version of Minecraft for Oculus Rift can be played for free. In this game, you can build anything you visualize and visit different worlds. You will have to survive while battling dangerous Mobs. The view in VR would be first-person instead of third-person. Both Rift and Rift S headsets support Minecraft.

In Minecraft VR, you can explore limitless worlds and construct anything you want, either simple homes or grand palaces. You can play in creative mode with infinite resources, or survival mode to mine deep into the world and create weapons and shields to fight off the hazardous crowd. You can play this game alone or with companions on your Xbox One and Windows 10.

Minecraft in Windows 10 is compatible with Oculus Rift headsets and Windows mixed reality, supporting all the features of Minecraft that you love to play.

Minecraft for Windows Mixed Reality

Presently, Windows Mixed Reality offers you many more alternatives, providing an impressive virtual environment. Simply connect the headset via USB, and you are all set.

Likewise, there are a ton of VR headsets that you can choose from. Many electronic manufacturers are making Windows mixed reality headsets.

Minecraft for PlayStation VR

  • Living Room Mode
  • Immersive Mode

Living Room Mode, as its name suggests, allows you to experience the VR version of the game by sitting in a lounge. Meanwhile, Immersive Mode allows you to move freely inside the game, as you would in reality. You can play this game in virtual reality as you would play normally. All the features are almost the same in VR, but the 3D effects will immerse you in the world of Minecraft like never before.

Minecraft for Oculus Quest

If you own an Oculus Quest, you can also play Minecraft in VR with this device. Yes, Oculus Quest is a standalone headset and Minecraft is not available for that. If you search Minecraft on the Oculus Quest store you will not find it. However, you need not spend money on a new headset! Oculus Quest supports Oculus Link, which allows you to connect your headset with a PC – you just need to buy an Oculus Link cable. The Oculus Quest will behave like a traditional tethered headset, and you can play the PC version of Minecraft using this device.

Then press the triangle button to enter VR mode, this will turn VR mode on, and you will have two choices: immersive mode and living room mode. Use your D-pad toggles to choose between the two. For a truly immersive experience, select the immersive mode. 

For those using computers, phones, or other devices, you will need to turn your VR headset on, enabling VR mode on the game. You will need to purchase an Oculus Link cable to connect to your PC for those using an Oculus Quest. This does tether you to the PC but will allow you to enjoy the immersive game. 

If you run into any issues, be sure to consult your VR headset settings and your device to ensure they’re on and ready for VR mode.
