Hello

 

I want to add more blockstates and models to a button (for redstone) out of glazed terracotta.

Now i want to add a key control to change the model between ones with the same shape-orientation and and different texture-rotations, to match all possible rotations of the glazed terracotta-block.

I think, i van add a custom blockstate and expand the json files.

i also know the line for changing the blockstate for another model.

 

But how do i code a key-control for the block?

It should do the stuff above, if i aim at it and press a given key on the peyboard (for sample "R" for rotation)

I do not know of any for 1.15. However, the process isn't quite difficult from what I remember. Just create a final instance of the KeyBinding by using its constructor and then register using ClientRegistry#registerKeyBinding during the FMLClientSetupEvent. Remember that this is client-side only so any data received must be sent via packet to the server.

Is sent via packet to server only needed, if it should be used in multiplayer, too?

No, it's mandatory to send a client to server packet.

It's sad how much time mods spend saying "x is no longer supported on this forum. Please update to a modern version of Minecraft to receive support".

How do i now use the registered keybinding and how do i send a packet?

Use the keybinds using events, specifically InputEvent, packets are pretty well documented on the forge docs, but basically you want to use SimpleChannel#sendToServer with your custom packet.

I do it understand better with samples.

But i cannot find some about the inputEvent for 1.15 on the web...

 

And i don´t know, where i should place the stuff about the package.

In the block-class?

In the main-class?

some where else?

Have you even looked at InputEvent in your IDE? Use isKeyDown from it for your purposes. What do you mean by "stuff about the package"?

I mean the line of code, that sends the data package from client to server.

Do you have a packet system? If not then look at the Forge documentation to make one

I´m not sure, how to find the InputEvent in my ide...

Actualla most times i used call-hirachy or "find references" to find stuff.

But i have nothing open, that has references to InputEvent.

And i don´t know, where in the big file-system of the referenced library it is.

In the forgedocs page about the simple channel packet system, it says register packet.

But it does not tell, where i have to call INSTANCE.registerMessage.

What is the right location for this?

Main constructor.

It also doesn´t show the call-line, filled with all the needed parameters...

 

And for this, i don´t know, how to replace "MyMessage"

    public static void handle(MyMessage msg, Supplier<NetworkEvent.Context> ctx)
    {
        ctx.get().enqueueWork(() ->
        {
            // Work that needs to be threadsafe (most work)
            EntityPlayerMP sender = ctx.get().getSender(); // the client that sent this packet
            // do stuff
        }
        );
        
        ctx.get().setPacketHandled(true);
    }

EntityPlayerMP must be ServerPlayerEntity to have this line free from red underscored errors.

Must i call INSTANCE.sendToServer(new MyMessage()) in the net.minecraftforge.client.event.InputEvent.KeyInputEvent?

 

And where do i place this event?

And how exactly do i define the content of the packet?

 

Yes, you must. The event should go in an event handler. All of the code you want to run on sending the packet should be called after ctx.enqueWork in handle, the content of the packet is whatever you want!

    • I figured it out! i had an extra "2" in the port. A personal paste error! Darn.
    • The voicechat-server.toml file is invalid. Correct it or delete it to regenerate the default.
    • 1.12 is no longer supported on this forum. Please update to a modern version of Minecraft to receive support.
    • debug.log must be explicitly enabled when using curse launcher, maybe that is the issue.
