X and Y genes in the Ronin blockchain

[herenickname]

Hello, at the moment I am analyzing the Ronin blockchain and cannot figure out how the axie body parts and genes can be decoded.

The code I ran:

import Web3 from 'web3'

const web3 = new Web3('https://api.roninchain.com/rpc')
const axieContract = new web3.eth.Contract(ABI, axieContractAddress)

axieContract.methods.axie(4950464).call().then(console.log)

RPC Response:

Can your library help me get genes for the genes.x and genes.y I have?
Do you have any idea how to convert this to the SHA hash your library needs?

I tried to concatenate the X and Y gene strings, but nothing was happened.

const axieState = await axieContract.methods.axie(4950464).call()
const sha512 = crypto
        .createHash('sha512')
        .update(axieState.genes.x + axieState.genes.y)
        .digest('hex')
const axieGene = new AxieGene(sha512, HexType.Bit512)

Error: cannot recognize class

Ensure that the sha512 value that you're passing is a string of hex prefixed with 0x

Ensure that the sha512 value that you're passing is a string of hex prefixed with 0x

Generated sha512 string is not contain '0x' prefix, anyway, your parser will remove it.

I found the answer, here is it:

const axieState = await axieContract.methods.axie(4950464).call()

const x = BigInt(axieState.genes.x).toString(2).padStart(256, '0')
const y = BigInt(axieState.genes.y).toString(2).padStart(256, '0')
const z = BigInt('0b' + (x + y)).toString(16)

const axieGene = new AxieGene(z, HexType.Bit512)
