Get EntityPlayer(MP) in KeyInputEvent

[yohannlog]

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.

But...I fix it thre problem and now I have a crash when I open the GUI;

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