1. create the keybinding
2. Register the keybinding with ClientRegistry#registerKeyBinding in the FMLClientSetupEvent
3. uses the ClientTickEvent to check whether your KeyBinding is pressed and send a custom packet to the server (using a SimpleChannel)
4. execute the code / your action in the handle method of your custom message (packet)

okay the whole thing was very theoretical, here a practical example

KeyBinding
Registration
ClientTickEvent
Message (Packet)

Subscribe to ClientTickEvent, check if the phase is START. Check if your key binding has been pressed and if so, perform whatever action you want.

Thank you for your help.

And without you I would never have found out how to run the code.

I did everything like you did but it always crashes when I try it.

[Davidthemodder]

public static final KeyBinding KEY = new KeyBinding("Fly",GLFW.GLFW_KEY_V, "Ultimate Sheep Mod");

@SubscribeEvent public static void doClientSetup(FMLClientSetupEvent event){ ClientRegistry.registerKeyBinding(UltimateSheepMod.KEY); }

 

@SubscribeEvent public static void fly(TickEvent.ClientTickEvent event){ if(event.phase == TickEvent.Phase.START){ if(UltimateSheepMod.KEY.isKeyDown()){ ModPacketHandler.simpleChannel.sendToServer(new FlyActivateMessage()); } } }

 

public class ModPacketHandler { private static final String version = "1"; private static int id = 0; public static SimpleChannel simpleChannel; public static void init(){ simpleChannel = NetworkRegistry.newSimpleChannel(new ResourceLocation("usm:simple_channel"), () -> version, version::equals, version::equals); simpleChannel.registerMessage(id++, FlyActivateMessage.class, FlyActivateMessage::encode, FlyActivateMessage::decode, FlyActivateMessage::handle, Optional.of(NetworkDirection.PLAY_TO_SERVER)); } }

 

public class FlyActivateMessage { public static void encode(FlyActivateMessage message,PacketBuffer packetBuffer) { } public static FlyActivateMessage decode(PacketBuffer packetBuffer) { return new FlyActivateMessage(); } public static void handle(FlyActivateMessage message, Supplier<NetworkEvent.Context> networkContext) { ServerPlayerEntity player = networkContext.get().getSender(); networkContext.get().enqueueWork(() -> { }); networkContext.get().setPacketHandled(true); } }

looks okay, do you register the packet handler?

[Davidthemodder]

How?

you only register your packet handler on the client side, move the FMLCommonSetup event to a class without Dist#CLIENT

the packet handler must be registered on both sides (server and client), there must be no dist in the EventBusSubscriber

Can I just do it twice?

EDIT: Like on Server and on the Client in the two classes?

no, do this in one class, if you have a class for server event and one for client events then create one for both (ModCommonEvent)
