So what i'm trying to do is whenever a certain word is being typed in chat by anyone, it would message the player something. But whenever I use this event the chat stops working, and I cannot chat anymore not even type a command + I cannot see what other players type. @SubscribeEvent public void onChat(final ClientChatReceivedEvent event) throws IOException { final String m = event.message.getUnformattedText(); if (m.equals("wtflol")) { Minecraft.getMinecraft().thePlayer.addChatComponentMessage(new ChatComponentText("test")); } } }
