[1.12.2][SOLVED!] Capabilities and networking

[MCrafterzz 10]

The problem with that is that it doesn't provide the player or any other information that can be used to get that. I need the players as I otherwise can't add the capability to it

[Alexiy 21]

Of course it doesn't, because this event is only fired on client, so you can get the client player "Minecraft.getMinecraft().player" as usual.

[Draco18s 2403]

Which is fired for EVERY key that's pressed EVERY time its pressed.

You should not use it.

Use the ClientTickEvent

I did it like this last time to open my backpack item via a keybind. It shouldnt be that much different from 1.7.10 to 1.12.2

I have fixed that. Now I only need to send the data over to the server which isn't currently working.

 

KeybindMessage: https://pastebin.com/neQQZggT

KeybindMessage: https://pastebin.com/aTCipDuP (Here I'm lost)

What should I add to get it working. Currently it only works on the client side.

• Your fromBytes method does nothing with the read value.
• In the message handler you need to perform the action you want the key binding to have.

[MCrafterzz 10]

What I want is to move the client capability value to the server side of the itemblock methoud. How can this be achived? I can't do the action in message handler as it should be done when placing my block.

That is not the action for the keybinding then. The action for the keybinding is "hey, I am pressing the keybind now". You need to store that state in the capability.

[MCrafterzz 10]

Currently I'm detecting a key press on the client side and then storing that value as a player capability. But on the capability page on the docs it sais that the data has to be sent over to the server side with packets so that it somehow can be accessed on the SERVER side in the itemblock methoud. This is where I'm stuck. If you need any more code I can post it.

Here is the eventhandler class: https://pastebin.com/MAhwwzgM

[diesieben07 7594]

In the setKeybindDown method you can detect if the state changed. If it has, send the packet to the server.

Then on the server when the packet is received, obtain the capability instance from the player that sent the packet and also update the state there.

[MCrafterzz 10]

I've updated my Eventhandler:

And my KeybindMessageHandler: https://pastebin.com/SNGBFhqs

 

But it still doesn't work

 

EDIT: KeybindMessage: https://pastebin.com/pD2CdBMN

EDIT 2: Printing out Main.logger.warn(keybindDown) in the onMessage methoud always prints out false even tho the value sent is true.

better show the KeybindMessage class of yours.

 

in your capability you can create a setter method and set the value on the server. do not forget to save it in Nbt aswell.

 

Make sure that you register your packet for the SERVER side 
    

Quote

    INSTANCE.registerMessage(Packet.Handler.class, packet.class, ID of your packet, Side.SERVER);

 

onMessage you take the Entityplayer and get the CAPABILITY for that player.

Quote

player.getCapability().getyourmethodtogetthevalueyouwant();

 

 

now you use your setter to set the value you want. the server will save that if you fill serializeNBT and deserializeNBT in your CAPABILITY

 

Quote

player.getCapability().setyourmethodtosetthevalueyouwant();

I updated my previous message

[NextInima 0]

do you have checked what you have send to the server?

 

1.   public KeybindMessage(boolean keybindDown) {
2.         this.keybindDown = keybindDown;
   1. System.out.println(the key is: "+keybindDown);
3.     }

 

            this.keybindDown = ByteBufUtils.readBoolean((buf);

Why are you no longer using setKeybindDown on the client?

 

This is still the case, you need to fix this:

Not applicable here at all.

[NextInima 0]

yes you are right, i forgot that he want to work with the value and do not want to save it.. sry

[MCrafterzz 10]

I think I finally got it working I changed the fromBytes to: keyboardDown = buf.readBoolean()
