Error on htme connection.

I followed the tutorial, and searched around for a solution, but came up empty. The host can play the game just fine, but when a second player connects successfully, this error comes up.

Try use the template from here: https://the-any-key.itch.io/gmnet-base-template
Also note that the marketplace version is outdated.

Thank you for the reply, however the issue still persists. I did as you said and the same error came up when trying to connect.

And you have not changed anything, you just try the demo?
Also note that you should use Game maker 1.4.1804. The 1.4.9999 got nasty network bugs.

I hope this isn’t too late but I’ve seen a similar error and to my knowledge the error occurs when two instances(of the same ID) are calling the mp_MapsyncIn at the same time and thus are both trying to write to the same value my guess would be this is happening in your case because you are missing the: if (htme_isLocal) check before the map sync in is called

I use gms2, it can work, thank you.

Good to know the 1.4.9999 is bugged. been trying to use it for a project and running into a ton of random issues
