Construct a Web3 Multiplayer Recreation
You possibly can simply construct all types of Web3 multiplayer video games utilizing the above-presented instruments. In The Playground, we ensured that the multiplayer characteristic matches gamers collectively and synchronizes their information. As such, each participant can see different gamers’ character positions, account particulars, and many others. We coated these elements with Unity. However, we used Moralis to include ERC-20 and ERC-721 tokens into our recreation.
Observe: There are good contracts behind each token, together with our in-game instance property. Nevertheless, the creation and deployment of those contracts exceed the aim of this tutorial. Nevertheless, you possibly can be taught extra about it from our earlier Unity tutorials on the Moralis YouTube channel and Web3 weblog. Additionally, we gained’t go into particulars about Web3 authentication on this article.
In The Playground, our ERC-20 tokens characterize gold cash, whereas ERC-721 tokens characterize NFT awards. This additionally signifies that gamers personal their in-game property. Moreover, these property are immutable and will be transferred to different accounts. Gamers can try this inside the sport or outdoors the sport utilizing their Web3 wallets. Nonetheless, since these property are saved on the blockchain, particulars about transfers and possession are absolutely clear.
With that mentioned, it’s time to look inside our instance Unity multiplayer Web3 recreation.
The Playground – Demo

To begin a recreation, we have to click on on the “Play Recreation” button, which shows our instance room:
Earlier than our character seems, we have to click on on both the “Begin” or “Be a part of” buttons. Nevertheless, since that is the primary participant, we have to go along with the “host” possibility. Let’s first run a number of builds to simulate the multiplayer possibility correctly:
Native 4-Participant Demonstration
As you possibly can see within the picture above, we now have 4 totally different gamers, all authenticated. There’s no restrict to what number of gamers can be a part of. Nevertheless, we can’t show greater than 4 on the identical time. Should you look intently, you’ll see that apart from the top-left participant, we used the identical handle for the opposite three gamers. Therefore, any token transactions will mirror on their screens. In actuality, each participant would have their very own pockets.
Every participant may randomize their nicknames and reset their participant information (to be handled as a brand new participant) through the “View Setting” possibility:
Moreover, we hit the “Play Recreation” button on all 4 situations. Then, we use the top-right construct (P1) participant to click on on the “Begin (Host)” button whereas hitting the “Be a part of” button on the opposite three builds (P2, P3, and P4):
In consequence, every participant now sees all the opposite three gamers, together with their nicknames and pockets addresses:
By shifting any participant round, we will take a look at the synchronization (see the video under, beginning at 10:11). The physics additionally works – the characters can’t go into the lava pit, for example, however they will cross the bridge. Additionally, gamers collide correctly. Moreover, any participant can hit the “area” button to say hiya:
Except for Web3 authentication, all the above options are coated by Unity Multiplayer. Nevertheless, gamers may click on on different gamers to switch both their gold cash (ERC-20) or their NFT rewards (ERC-721).
Token Transfers Inside The Playground
So, let’s use the top-left participant (P1) to switch tokens to a different participant. Keep in mind, all of them use the identical handle; therefore, all of them will obtain tokens. After clicking on one other participant, the sender will get to decide on which tokens to ship. Furthermore, the interface additionally shows the addresses concerned in a possible transaction:
As soon as the participant selects which property to ship, the participant should verify the transaction utilizing their pockets (the related pockets):
The “Ready For Transaction” message seems after confirming the transaction with the related pockets:
Lastly, after confirming the on-chain transaction, the recipient first receives a message:
Quickly after the message arrives, the recipient additionally receives tokens, that are mirrored within the participant’s steadiness (from 150 to 175):
After all, the identical applies when transferring prizes (ERC-721 NFTs).
