Events, Retrieve Balance and NFTs

The Unity SDK uses delegates to offer an event-based system that allows users to observe balance changes and NFTs.

You can register for events from anywhere. Here are some examples:

On Login:

private void OnEnable()
{
    Web3.OnLogin += OnLogin;
}


private void OnDisable()
{
    Web3.OnLogin -= OnLogin;
}


private void OnLogin(Account account)
{
    Debug.Log(account.PublicKey);
}

On Balance Change:

private void OnEnable()
{
    Web3.OnBalanceChange += OnBalanceChange;
}


private void OnDisable()
{
    Web3.OnBalanceChange -= OnBalanceChange;
}


private void OnBalanceChange(double solBalance)
{
    Debug.Log($"Balance changed to {solBalance}");
}

NFTs:

private void OnEnable()
{
    Web3.OnNFTsUpdate += OnNFTsUpdate;
}


private void OnDisable()
{
    Web3.OnNFTsUpdate -= OnNFTsUpdate;
}


private void OnNFTsUpdate(List<Nft> nfts, int total)
{
    Debug.Log($"NFTs updated. Total: {total}");
}
