Loot System Setup
Begin by navigating to the “Sport” scene:
That is the one display of our Web3 role-playing sport, and it’s the place all of the motion occurs. As an illustration, “AuthenticationKit” takes care of the Web3 authentication as offered within the demo above. You should utilize the video beneath for extra particulars, beginning at 8:00. That is additionally the place you’ll learn to run your occasion of our dapp in Unity. Because you haven’t deployed your situations of our sensible contracts but, sure functionalities of the sport is not going to work. Nevertheless, you may already log in utilizing your cell crypto pockets after which transfer the character.
You’ll be taught extra about “GameManager”, which listens to “AuthenticationKit”, within the video at 10:07. You’ll additionally be taught that we used a third-party asset (Surge) to implement a state machine. Thus, we may convert our “GameManager” right into a state machine. As such, the latter has a number of states that our Web3 role-playing sport goes by means of:
This type of method makes issues fairly easy as you may add code to any of the included states. Utilizing the “ChangeState” operate makes shifting between states extraordinarily easy. So far as the Web3 performance goes, the “Victory” state involves play. For an in depth code walkthrough of the “Victory” script, use the video beneath (14:35). This state is activated as soon as the boss is defeated. After he’s defeated, he’ll drop the gadgets and the expertise factors, which we determined to placed on the chain. Definitely, we’d like a method to populate this stuff and runes. Thankfully, we are able to use the Moralis dashboard (database) to retailer these property. Then we use the “PopulateItemFromDB” and “PopulateRunes” capabilities, which include Moralis’ strategies that make querying fairly simple.

Which means should you run your occasion of the Web3 role-playing sport once more and efficiently defeat the boss, this stuff will seem:
Notice: We determined to simplify issues for you by making all the information associated to runes native. Because of this, you don’t want to make use of your database for that facet of the sport.
Good Contracts to Get On-Chain Web3 Position-Enjoying Sport Gadgets
With a view to get the “PickingUpItem” and “PickingUpRune” states to operate, it’s good to deploy the correct sensible contracts. Thankfully, you don’t have to be a Solidity professional to do that. Platforms similar to OpenZeppelin offer you verified sensible contract templates. Then you should use Remix or Hardhat to deploy these contracts. Now, to simplify issues extra, you may simply copy our sensible contracts (“SmartContracts“). Additionally, as talked about earlier, we are going to use Hardhat to do that. For detailed directions, use the video beneath, beginning at 23:11. As well as, all of the instructions you want are offered within the “directions.txt” file.
When you efficiently set up Hardhat and all dependencies, you may copy the code of the “GameItem” contract. Then, you’ll be capable of use the “Greeter.sol” template file (26:28). Subsequent, you’ll apply minor tweaks to the “sample-script.js” file. That is additionally the place you’ll learn to use Hardhat to confirm sensible contracts utilizing PolygonScan API keys:
As well as, additionally, you will use Moralis Speedy Nodes to acquire Mumbai endpoints:
Notice: To deploy your sensible contracts, you’ll want some “play” MATIC. Thankfully, you should use the Mumbai testnet faucet for that function.
After efficiently making use of all of the tweaks, it is possible for you to to compile, deploy, and confirm your occasion of the “GameItem” contract. As such, you’ll be capable of view its particulars on PolygonScan. Then, you’ll want to repeat your contract’s handle and ABI into the “GameManager” script in Unity (36:56):
Transferring ahead, you’ll repeat the above course of for the second sensible contract (“Rune“), which covers the transactions associated to the expertise factors.
Minting Gadgets and Runes as ERC Tokens
After efficiently deploying each of your Web3 contracts, your occasion of our Web3 role-playing sport is absolutely useful. Now, it’s useful to take a more in-depth take a look at how the “PickingUpItem” and “PickingUpRune” scripts execute the minting course of. Thus, be sure to look at the video beneath, beginning at 42:00, for an in depth code walkthrough. Basically, “Moralis.ExecuteContractFunction” does many of the heavy lifting in each scripts.
