Upgradeable ERC721 - import contract and use initialize function

Smart Contracts
1

Hi.

I have a contract

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts-upgradeable/proxy/utils/Initializable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC721/ERC721Upgradeable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC721/extensions/ERC721URIStorageUpgradeable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC721/extensions/ERC721EnumerableUpgradeable.sol";
import "@openzeppelin/contracts-upgradeable/access/OwnableUpgradeable.sol";
import "./safeMath.sol";
import "./Counters.sol";
import "./IERC20Standard.sol";
import "./GameContract.sol";

contract NFT721Contract is Initializable, ERC721URIStorageUpgradeable, ERC721EnumerableUpgradeable, OwnableUpgradeable  {

...

 function initialize() public initializer {
    OwnableUpgradeable.__Ownable_init();
    __ERC721_init("Name", "Symb");
 }

...
}

Use deploy

const { ethers, upgrades } = require('hardhat');

async function main() {
    const NFT721Contract = await ethers.getContractFactory('NFT721Contract');
    console.log('Deploying NFT...');
    const nftContract = await upgrades.deployProxy(NFT721Contract, { initializer: 'initialize' });
    await nftContract.deployed();
    console.log('NFT - deployed to:', nftContract.address);
}

main();

After deployment, I have NFTs available.
But the GameContract was not initialized.

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;

import "@openzeppelin/contracts-upgradeable/proxy/utils/Initializable.sol";
import "@openzeppelin/contracts-upgradeable/token/ERC721/ERC721Upgradeable.sol";
import "@openzeppelin/contracts-upgradeable/access/OwnableUpgradeable.sol";
import "./safeMath.sol";
import "./IERC20Standard.sol";
import "./NFT721Contract.sol";

contract GameContract is Initializable, OwnableUpgradeable {
    ...
    
    bool public gameStatus;

    function initialize() public initializer {
        OwnableUpgradeable.__Ownable_init();
        gameStatus = true;
    }

    ...
}

There are other variables in the initialization method and they are left empty after deployment.

Heeelp :slight_smile:

I've been trying to tie contracts for 3 days...

Or are they impossible for one proxy address?
