custom joinserver screen

[wise scarab]

i want to present a custom screen before player joins my server . so how can i modify the join server button to dont make immediate connection and let me present a screen
how to do it the easy way

[proven basin]

You'll probably mixin to wherever players join the server, I know that much. I don't know how screen handling works outside a world though.

i need to do it before connection happens

[proven basin]

Yes, mixin to before the server connection is sent. You can't just do the button since there's multiple buttons and keyboard inputs that work.

i dont know anything about mixins. any way through events or something else

[proven basin]

I doubt it. Mixins aren't too bad to learn though.

i am new so dont roast me if i speak some gibberish
cant i just stop the ClientConnectionEvent.Join event from continuing then do my screen stuff . then calling a joinserver method if it exists

[proven basin]

Possibly? If that event is cancelable. I don't know if it is and can't check right now. If it is, that's probably the best thing to do, yeah.
