The Technology Behind Your Favourite Video Games

Technology behind video games

Gaming is a more popular hobby now than it has been at any other moment in time. The inventions of cloud gaming and worldwide internet connectivity have made it more accessible for all, regardless of the country that you live in. 

Massive investment into gaming development has meant there are a greater range of gaming platforms for people to choose from and the proliferation of smartphone gaming has only compounded this. However, whilst more of us are enjoying gaming than ever, how many of us have stopped to think about the technology that makes it all possible? 

We’re going to look at some of the most commonly used tech, as well as some of the most pioneering, to shine a light on how the world’s favorite video games actually work.

Random Number Generators

Games that rely on an element of chance usually require a random number generator. Games that you might find on CafeCasino, such as slots titles, are a great example, as they require a totally random chance: as opposed to a game of roulette, where you’ve got a chance out of a set number, slot games have an almost limitless number of possibilities. This makes them the sort of game that requires a random number generator, to ensure that both player and casino have a fair chance. 

Random number generators work by taking a seed number, sometimes from the movement of a trackpad, sometimes a pause between clicks, usually measured in fractions of a second and put this seed number through a complex mathematical equation. 

Each time the equation will throw up a new number and this will be turned into the time it takes for the reels to stop spinning. It’s a surprisingly complex model for such a simple task, but when ensuring both randomness and fairness, it’s the only way for these sorts of games to work.

Whilst random number generators have been around for decades, this next kind of technology is much more recent. In order to understand NFTs, it’s important to understand what an NFT is. NFT stands for Non-Fungible Token, meaning a token that cannot be broken down into parts and can’t be replicated. 

They’re unique in nature and use blockchain technology to ensure that they cannot be stolen or copied. This uniqueness is one of the things that gives them value, meaning that people might want to play games where it’s possible to earn them. There are lots of companies within the NFT marketplace that have brought NFT gaming to the market, but two of the most successful are Crypto Kitties and Axie Infinity. Both of these games share the common theme that you can breed and collect animals, kitties in the former and axies in the latter. 

By using the codes in NFTs as genetics, NFTs can be ‘bred’ together to create new NFTs, each with its own unique DNA. Users can trade these for cryptocurrency, other NFTs, or bonuses in the game. It’s a complex model, but one that allows players to effectively earn whilst they’re playing, so naturally, this sector is growing extremely quickly.

Whilst random number generators have been around for a long time and NFTs are making their presence felt on the gaming industry, gesture-control technology is super new in comparison. This technology uses our gestures to enable to control a game, that is, instead of using a touchpad or a controller, we can swipe using our hands, removing the need for a physical user interface. 

This tech is still pretty new to the gaming industry, but its already predicted that this year will see an increase in the global market by $23.5 billion. It’s off to a strong start already, particularly with the release of Mario Kart for Switch, Wii, and Android, all of which have utilized gesture recognition to some level. How does the technology work though? 

Currently, all available gesture technology works on hands only, with the most advanced being able to track 22 different points in the human hand. This means that 3D cameras can read the way that the hand is moving and feed the information back to the game, allowing it to behave accordingly. Of course, this all happens lightning fast, making it appear almost instantaneous.

The Future

This sort of gesture control technology has been developed hand in hand with facial recognition technology, which so far hasn’t been implemented into games yet. It’s a certainty that facial recognition technology will find its way into games within the next year, some reporting that it will initially be used to allow us to create avatars that emote in the same way as us in the Metaverse

However, it is first brought to market, this technology is a super exciting one. Being able to see a playable character use the same facial expressions as you will bring a whole new level of realism to gaming which we’re very excited to see.
