Get EntityPlayer(MP) in KeyInputEvent

Posted August 5, 20187 yr

Hello everyone,

I have some problems, including one in particular. I created an event with KeyInputEvent class but, the problem, I created a GUI and to open him, I push a keyboard key but I need a player argument and this event do not give a player argument.

So, I would like to ask a question: How can I have access to EntityPlayer or EntityPlayerMP (I prefer) with this event ?

PS: If you want to see my classes, say it to me.

Thank you.

I don't think you understand how events work.

http://mcforge.readthedocs.io/en/latest/events/intro/

Apparently I'm a complete and utter jerk and come to this forum just like to make fun of people, be confrontational, and make your personal life miserable. If you think this is the case, JUST REPORT ME. Otherwise you're just going to get reported when you reply to my posts and point it out, because odds are, I was trying to be nice.

Exception: If you do not understand Java, I WILL NOT HELP YOU and your thread will get locked.

DO NOT PM ME WITH PROBLEMS. No help will be given.

After a few minutes of research, I think is a problem with the network system and for the NoSuchMethodException.is the same problem.
