Web3 Game Development with GlacierDB

In this tutorial, we'll walk you through creating a simple monster battling game using GlacierDB and Web3.

Prerequisites:

• Familiarity with React and TypeScript.
• An Ethereum wallet, e.g., MetaMask.
• Node.js installed.
• Vite and pnpm installed for our project setup.

1. Project Setup

pnpm create vite my-web3-game --template react-ts
cd my-web3-game
pnpm add @glacier-network/client react-bootstrap ethers

2. Connect to Ethereum Wallet

Create a useWallet.ts hook, same as the previous useWallet.ts content.

3. Connect to GlacierDB

useGlacier.ts hook:

import { useState, useEffect, useCallback, useMemo } from 'react'
import { GlacierClient } from '@glacier-network/client'
import useWallet from './useWallet'

export default function useGlacier() {
  const [monsters, setMonsters] = useState<any[]>([])
  const { provider, account, connect } = useWallet()

  const client = useMemo(() => {
    return new GlacierClient('https://your-glacier-endpoint.com', { provider })
  }, [provider])

  // ... (same as the previous `useGlacier.ts` content)

  return {
    monsters,
    createMonster,
    updateMonster,
    connect
  }
}

4. Game Logic

Creating a New Monster

createMonster.ts:

import { useGlacier } from './useGlacier'

export const createNewMonster = (name, image, attributes) => {
  const { createMonster } = useGlacier()
  const monster = {
    name,
    image,
    attributes,
    ownerId: window.ethereum.selectedAddress
  }
  createMonster(monster)
}

Trading Monsters

tradeMonster.ts:

import { useGlacier } from './useGlacier'

export const tradeMonster = (myMonsterId, theirMonsterId) => {
  const { updateMonster } = useGlacier()
  const myAddress = window.ethereum.selectedAddress
  updateMonster(myMonsterId, { ownerId: theirAddress })
  updateMonster(theirMonsterId, { ownerId: myAddress })
}

Battle Logic

battle.ts:

import { useGlacier } from './useGlacier'

export const battle = (myMonster, opponentMonster) => {
  const { updateMonster } = useGlacier()
  const damageToOpponent = Math.max(
    myMonster.attributes.attack - opponentMonster.attributes.defense,
    0
  )
  const damageToMe = Math.max(
    opponentMonster.attributes.attack - myMonster.attributes.defense,
    0
  )
  const myUpdatedHealth = myMonster.attributes.health - damageToMe
  const opponentUpdatedHealth =
    opponentMonster.attributes.health - damageToOpponent
  updateMonster(myMonster.id, { 'attributes.health': myUpdatedHealth })
  updateMonster(opponentMonster.id, {
    'attributes.health': opponentUpdatedHealth
  })
}

5. Build the UI

App.tsx:

import React, { useState } from 'react'
import { Button, Form, ListGroup } from 'react-bootstrap'
import { createNewMonster, battle } from './gameLogic'
import useGlacier from './useGlacier'

export default function App() {
  const [name, setName] = useState('')
  const { account, monsters, connect } = useGlacier()

  // Handle monster creation, battling, etc. in this component

  return (
    // JSX for your game UI
  )
}

6. Wrap-Up

Now, you have a basic structure for a Web3 monster battling game using GlacierDB. Expand on this foundation with richer game mechanics, enhanced UI/UX, and integration of Ethereum smart contracts for more advanced features like secure monster trading.

Happy coding!
