Hi! First, thank you for this tutorial. its so amazing. But i stuck on script. I made my custom scene with Web3 Game Kit Package v1.2.1. What i need to change in script, with new version of SDK, because system cant find it. Thank you!

Hi @Navajjoo,

Yeah, the problem here is that this project is using an old version of the SDK. There was a big change in the SDK about 1 month ago with some breaking changes. Forget about the old GameManager, create a new one and start from there. If you check AuthenticationKit, on the OnConnected event you can add your new GameManager function to start the game or do whatever you need.

Cheers!

Hey im having issues on build(mac,windows,linux) where the QR code doesn’t populate. works fine when you test in unity. any help would be appreciated thanks.

#73

Do you get any errors? This is the project you used?

#74

no erros yes this project or the same one khk.cryptech screen shotted

#75

This project is quite outdated now and using an older Unity editor version as well (2020.3.2) - which editor version are you using? Are you familiar with Unity and the Moralis game kit? If so you could migrate the functionality/code to a new project.

#76

A clone of that project works for me after when built on Windows (and adding serverUrl and appId to Prefab) - Unity Editor version 2020.3.2.

#77

im using 2021.3.6, strange yes it works in dev for me not on build. Will migrate over if i cant resolve this. maybe a mac issue.

#78

Try using the same editor version 2020.3.2 as the original project.
