In a new Unity project:
1: Add Moralis game kit package and import default scene from Moralis Web3 Unity SDK/Demos/Introduction.
2: Add your self hosted server Dapp URL and Dapp ID e.g. http://127.0.0.1:1337/server and 001
3: Open Moralis Web3 Unity SDK package > Runtime/Kits/AuthenticationKit/Scripts/AuthenticationKit.cs
The Unity SDK relies on getServerTime returning a valid value but the self hosted server needs it to return null for authentication to work.
Edit the getServerTime code at lines 257 and 358 to check if the response is null:
if (serverTimeResponse != null)
{
Debug.LogError("Failed to retrieve server time from Moralis Server!");
}
4: Above comment // Try to sign and catch the Exception when a user cancels the request, add these new lines:
IDictionary<string, object> requestMessageParams = new Dictionary<string, object>();
requestMessageParams.Add("address", address);
requestMessageParams.Add("chain", session.ChainId);
requestMessageParams.Add("network", "evm");
Dictionary<string, object> authMessage = await Moralis.Cloud.RunAsync<Dictionary<string, object>>("requestMessage", requestMessageParams);
signMessage = authMessage["message"].ToString();
5: Workaround for insufficient auth error with signing in as an existing user, open Moralis Web3 Unity SDK package > Runtime/Core/Platform/Services/ClientServices/MoralisUserService.cs and before await user.SaveAsync() at line 102, add:
user.authData.Clear();
await user.SaveAsync();
6: Test logging in with WalletConnect (click on Game tab in Unity editor first). If it works, there will be an error related to GetNativeBalance but it should show the wallet address on screen.
Error unauthorized when calling API with SDK methods
There is a missing header that is required, workaround is to open Moralis Web3 Unity SDK package > Runtime/Web3Api/Client/ApiClient.cs and under existing default headers, add x-parse-application-id:
_defaultHeaderMap.Add("x-moralis-platform-version", "v1.2.10");
_defaultHeaderMap.Add("x-parse-application-id", Moralis.DappId);
Or add this header from your Parse server (Express) as middleware in src/index.ts:
app.use('/server/functions/:functionName', (req, res, next) => {
req.headers['x-parse-application-id'] = '001';
next();
});
app.use(`/server`, parseServer);
Alternatively instead of using the SDK methods you can call the corresponding cloud function for the API method e.g. for GetNativeBalance in CongratulationsController.cs from demo scene:
Replace:
NativeBalance balanceResponse = await Moralis.Web3Api.Account.GetNativeBalance(user.ethAddress, Moralis.CurrentChain.EnumValue);
With:
using System.Collections.Generic; // for Dictionary
IDictionary<string, object> balanceParams = new Dictionary<string, object>();
balanceParams.Add("address", user.ethAddress);
balanceParams.Add("chain", Moralis.CurrentChain.ChainId);
// WebGL requestMessageParams.Add("chain", Web3GL.ChainId());
Dictionary<string, object> balanceResponse = await Moralis.Cloud.RunAsync<Dictionary<string, object>>("getNativeBalance", balanceParams);
// previously balanceResponse.Balance
balanceResponse["balance"].ToString()
For WebGL, follow the same steps in the code above in the same AuthenticationKit.cs file (near the top) and use Web3GL.ChainId() instead of session.ChainId.
Tested only up to basic authentication (WalletConnect and WebGL) and with calling API:
- Moralis Game Kit version: 1.2.10
- Unity editor version: 2021.3.4
