You can change player tablist header and footer by creating ClientboundTabListPacket and sending it to player. Example: public static ClientboundTabListPacket tabListPacket = new ClientboundTabListPacket(MutableComponent.create(new LiteralContents("Its header")), MutableComponent.create(new LiteralContents("Its footer"))); @SubscribeEvent public static void onLoggedInEvent(PlayerEvent.PlayerLoggedInEvent loggedInEvent) { ServerPlayer serverPlayer = (ServerPlayer) loggedInEvent.getEntity(); serverPlayer.connection.send(tabListPacket); }
