Build NFT metaverse with Unity on Algorand

Learn how to integrate Algorand blockchain into Unity by adding the .NET Algorand SDK via NuGet, configuring Visual Studio, and resolving Unity plugin dependencies for a functioning NFT metaverse project.

Learn how to implement a generic singleton in Unity to provide a single accessible instance for interacting with Algorand components, assets, and servers, ensuring consistent access across the scene.

Implement Algorand account logic to sign transactions and retrieve a user's assets, including NFT holdings on the testnet, using a server connection and asset lookup by ID.

Create two Algorand accounts: player and game main, using the assets menu, assign usernames and mnemonics, and prepare to transfer NFTs from the game main account to the player.

Instantiate the Algorand server object in Unity by creating a green server named algo server test and configure it with the testnet API address and token.

Instantiate gem coin, the game currency NFT, in Unity on Algorand by setting its name, decimals, 10 trillion supply, and metadata hash, then generate on testnet and verify asset ID.

Create a Unity Algorand manager as a singleton to coordinate the testnet server, main account, player account, and game token, and implement a balance display for the player's balance.

Explain how to perform an atomic buy of an NFT: verify funds and opt-in, then transfer game currency to the main account and deliver the NFT in one atomic transaction.

Create a dynamic NFT store UI in Unity by sizing and centering a panel, adding a grid layout group, duplicating item panels, and preparing a store item prefab.

Style the panel store item in Unity as an NFT by adding a chosen image and a TextMeshPro buy button, show an owned label when owned, then save the prefab.

Create the store item component script in Unity to toggle the buy button or owned text based on NFT ownership, wiring NFT asset, ownership flag, and panel grid layout.

Code the logic to mark items as owned, toggle the owned text, and enable the buy button, using the Algorand manager to buy assets and refresh the nft store ui.

Create and connect three Algorand NFT assets in Unity, configuring server, metadata, and sprites, then link them to the in-game store for a ready-to-test NFT metaverse.

Test displays of three nfts in the store and confirm they appear when you press play. The next lecture will implement the buy action and complete the store interaction.

Debug the buy NFT item flow in Unity with Algorand testnet, ensuring token balance, asset opt-in, and transaction refresh correctly reflect ownership after purchase.

Improve load performance by asynchronously fetching the player's balance from the Algorand network and updating the balance UI, reducing main-thread work and leaving the rest of the system responsive.

Install Node.js and npm to power a game server using a simple node stack; download from nodejs.org, choose your OS, and verify installation via the terminal.

Learn to initialize a node-based game server for a Unity metaverse, create a game-server folder, configure npm, and define index.js to interact with Unity and Algorand.

Learn to call the game server from Unity to retrieve a wallet balance using a web request, coroutines, and a local host endpoint in the Algorand manager.
