[SOLVED][1.8.8][Multiplayer] Catching Chat Clientside

[Draconwolver]

I am trying to develop a mod that takes input from a user through chat, therefore cancelling the chat message and doing whatever with what they said. I have tried using the ServerChatEvent, but cancelling it only works in singleplayer. Any help is much appreciated!

I'm not on my modding computer at the moment, so my apologies, but are you suggesting that CommandEvent works on multiplayer servers and can be cancelled to prevent sending the command?
