I am trying to send a message to the server to teleport the player. But when I add this code to the GUI it crashes.

 

BookMessageToServer bookMessageToServer = new BookMessageToServer();

CommonProxy.simpleNetworkWrapper.sendToServer(bookMessageToServer);

 

It looks like it's crashing inside the GUI. Is the client getting mixed up in server code? I am not sure what is going on here.

Yeah it looks like you're attempting to use gui/client stuff on the server.

You should post your code to a github repo and link it here for people to take a look. Posting snippets or individual classes usually doesn't provide enough information to pinpoint the issue.

Here is the repository it tried to make on GitHub, but GitHub sucks.

 

https://github.com/FrostDragonEmpire/MystRecraftedMod

 

 

Not sure if  GitHub uploaded my files or not. The desktop app said it did, but the web said it did not. So I am confused, therefore here is a dropbox link, this should work.

 

https://www.dropbox.com/sh/4w5qok10cnw8f8s/AABKW1eZ5FfdmBp_dtEf-Kj2a?dl=0

Looks like I got it to work, at least in single player, not sure how it’ll do with a dedicated server. Dimensional travel is still broken, I will have to do more research on that.
