Ok thanks for providing more information. So you’re trying this on Editor or after building to WebGL?

#25

I’m trying this on the default webGL template prior to publishing it online because when I try to run the game by hitting the play button a QR code pops up but after scanning the QR code nothing happens. When I run the instance the error pops up too.

#26

I see. The reason you can’t select WebGL template on this project is because it is using an older version of the SDK that didn’t support this.

I recommend you download and use this one if you want to build for WebGL. It’s the same as “Web3 Runescape Clone” and it also implements transactions between players:

Check it out and let me know :slight_smile:

Hi I still get this error when I tried running the file above

#28

What wallet are you using to scan the QR code?

#29

Hey I got it working but when I try to build it using WebGL I get the error

Hey any idea on how I can fix this?

#31

I can see you’re using MacOS so I can’t replicate your error but googling it I see it’s seems to happen after upgrading to MacOS 12.3.

Is this useful to you?

#32

Hi yes but unfortunately I cannot find the solution to the issue as nobody has replied to that post

#33

well, i used mac os and i dont think i have seen this errors, although that might not be the actual error, just cover up for something, does it build fine for windows ?

#34

Everything is fine in Windows. What MacOS version do you have @0xprof?

#35

latest, 12.3 monterey

#36

@0xprof have you tried building “Web3 Game Transactions” project to WebGL?

#37

no, i will try it today
send me a link to the github project, let me be sure it is the same one i have on my system

#38

Perfect, thanks!

#39

build is failing on my end, but it for a different reason, about 2 errors
something like this

System.ComponentModel.Win32Exception (2): No such file or directory
   at System.Diagnostics.Process.ForkAndExecProcess(String filename, String[] argv, String[] envp, String cwd, Boolean redirectStdin, Boolean redirectStdout, Boolean redirectStderr, Boolean setCredentials, UInt32 userId, UInt32 groupId, UInt32[] groups, Int32& stdinFd, Int32& stdoutFd, Int32& stderrFd, Boolean usesTerminal, Boolean throwOnNoExec)
   at System.Diagnostics.Process.StartCore(ProcessStartInfo startInfo)
   at System.Diagnostics.Process.Start()
#40

Seeing Win32Exception almost confirms that this is a OS-related issue.

@agupagu I would suggest to downgrade your MacOS version to BigSur or older and try to build the project to WebGL afterwards.

#41

Alright. Meanwhile I get this new error when I try to export the game into webGL

#42

Do i need to delete any one of the files? Because when I did i got a 100 more errors

#43

hello I’ve managed to publish the game onto localhost but when I try to build it into production on unity play I cant seem to connect to metamask as the prompt is not coming up. Does that mean unity play does not support web3.0 yet?
