Anything that needs an information from the Server, e.g. "Am i in a guild?" or "Did a Guild invite me?"

Hi everybody, I started to build a Guild-Mod with networking. The Client-To-Server Connections works properly and i already can create a Guild, but when i am trying to Check, if i am in a Guild, i either Receive no answer from the return or i get an Exception, when i directly send the Answer back to the Client. I need a check, if a player is in a Guild in the PlayerLoggedInEvent and when opening a Gui. Both lead to the same Exception and when i comment the line "ModMain.NETWORK.sendTo(nwm, serverPlayer);" the program don´t throw the Exception, but simpy dont work. How can in "answer" to a NetworkMessage?

Maybe because this is my first Forge-Mod??? I did not knew about this feature and tutorials on YT also did not speak about it. I will check it out, but what i were reading for now seemed to be pretty usable just wanna understand it before using it

This is a Guild System and this feature is for inviting players. The Leader enters the name in a Textbox and presses a button. This shall send a Message to this specific Player which gets handled by ClientChatReceivedEvent, which shows a Accept/Refuse dialog. All those Gui's and the function of accepting are working. Just the Message to the player is my last Problem. How can i manage, that the server knows, that it have to send this message. I thought about writing the player- and the guildname into a List, but then, this list must be checked constantly by the server and in case, send the message.

So, then what in your oppinion is applicable here???

Okay, then how I do get the meant player? I saw some stuff with Player lists, but them didnt worked for me either.

How do i send a Message to a specific Player? i tried following: EntityPlayer p = Minecraft.getMinecraft().world.getPlayerEntityByName(playername); if (p != null) { p.sendMessage(new TextComponentString(msg); } but this only causes the Message to appear on my own Chat. The addChatMessage also seem not to work anymore, so how is the new way? Can i prevent it from appearing in chat (gets handled by ClientChatReceivedEvent)
