That approach, you’ll have the ability to determine if you wish to roll up your sleeves transferring ahead. Though, we’re positive you’re desperate to create your individual occasion of a wonderful Unity dapp (decentralized utility). In any case, that is the quickest method to implement the “purchase NFTs in-game” function.
So, right here’s the preliminary display screen of our instance sport:
Because the above QR code suggests, gamers must scan it utilizing their Web3 wallets. For the aim of our demo, an instance person is utilizing MetaMask (authenticate with MetaMask). So, after scanning the code, the participant wants to substantiate their Web3 login inside their crypto pockets:
As soon as the participant has accomplished their Web3 authentication, the person can transfer their avatar. As such, they’ll go to the realm of the sport the place they’ll purchase NFTs in-game:
As soon as on the store counter, the person can work together with it and see the out there gadgets:
