Mission Construction Overview
Beginning at 4:25, you’re going to get an opportunity to undergo the construction of our mission. As such, you’ll study that you’ll find all of the property and scripts contained in the “_Project” folder:
Contained in the “Scenes” folder, you’ll even have an opportunity to seek out our “Recreation” scene. So far as the third-party property go, they await you contained in the “ThirdParty” folder. Nonetheless, inside “Moralis Web3 Unity SDK > Assets,” one can find the prefab that you simply’ll populate utilizing your Moralis server’s particulars. Then, beginning at 5:37, you’re going to get to have a look at the mission’s hierarchy:
The “MoralisStandaloneAuth” prefab will cowl Web3 authentication as introduced within the demo above. Additionally, “GameManager” will deal with recreation levels and set off some occasions. There’s additionally the “cameraManager” prefab, dealing with the avatar’s digicam and the digicam that focuses on the NFT store. That is additionally the place you’ll get to see Unity Cinemachine’s energy. Nonetheless, you’ll additionally check out “Participant, “World”, “UI parts”, and “EventSystems”. So far as the visible facets of the “purchase NFTs in-game” go, you’ll get to the NPC vendor and the store counter inside “World”:
Because the screenshot above signifies, the store counter’s collider will play a vital position. In spite of everything, it’ll set off the NFT store and provides gamers an opportunity to purchase NFTs in-game. Nonetheless, it’s “UI Components” that incorporates “ShopInventory” and “PlayerInventory”. Furthermore, you’ll study extra in regards to the new recreation enter system (“GameInputAction” asset) within the video.
Preliminary Moralis Setup
Now it’s time to finish the preliminary Moralis setup (10:00). Fortuitously, this setup is simple and takes little to no time. In case you haven’t carried out so but, first create your free Moralis account. In any other case, simply log in to your account and entry your Moralis admin panel.

The latter triggers the corresponding occasion, dealt with by the “PurchaseItemManager” script. The precise occasion handler (“ActivateItemPanel”) is triggered when gamers choose any explicit merchandise from the store. Lastly, it’s the “purchase” button that triggers the “PurchaseItem” operate (39:16):
That is the place Moralis’ SDK will mesmerize you once more with its energy (e.g., the “SaveToIpfs” technique). Due to Moralis’ IPFS integration, you simply create your NFTs’ metadata (JSON information). This metadata is then used to mint NFTs through the above-deployed sensible contract. Furthermore, the “PurchaseItemFromContract” operate triggers the contract in query. As well as, our scripts additionally be sure to delete the bought objects from the store stock (45:43).
Get Minted NFTs
Lastly, it’s time you study what permits objects to be displayed inside gamers’ stock and on OpenSea. For particulars, use the video under beginning at 49:46. For this side to operate correctly, “PlayerInventory” might want to do the heavy lifting.
