[1.19] Creating new Packet

[Zanckor]

Eya! I'm trying to create a new packet to send new max health of player to server side, but i've never made a packet before, so i hope if anyone can help me

 

That's how I change max health in an event: player.getAttribute(Attributes.MAX_HEALTH).setBaseValue(50D);

And that's my network class:

 

public class Network {

public static final String NETWORK_VERSION = "0.1.0";

public static final SimpleChannel CHANNEL = NetworkRegistry.
    newSimpleChannel(new ResourceLocation(DragonBallZ.MOD_ID, "network"),
        () -> NETWORK_VERSION,
        version -> version.equals(NETWORK_VERSION),
        version -> version.equals(NETWORK_VERSION));

public static void init(){
    int index = 0;
    SimpleChannel.MessageBuilder(maxHealthPacket.class, index++, NetworkDirection.PLAY_TO_SERVER);

  }
}

How can I add an attribute modifier?

[Zanckor]

I want to create a stat system, like a typical MMORPG, so, i'll create capabilities to each stat, for example, CON to health, if i've 50CON, It would be 50*5 (250) of health

[Zanckor]

I'm looking how to use addTransientAttributeModifiers, but i found nothing, may you send me an example please?

[Zanckor]

I'm still lost, I don't know how to do it lmao.

I want to change the life every time they increase CON, and from what I've seen it only works with a constant value?
Btw, I don't know if that's the case, but it gives me the feeling that it would change max health of all the players at the same time, not individually, but since I haven't been able to test it, I can't be sure.

And all the examples I found work in the entity class, not in events, so I think it would not work for me, since I want it to be updated when increasing the stat in a menu

Man I LOVE you ❤️

Finally, I made it before in the exact same way that i made it now, but idk why my event handler was not working.

[Zanckor]

Eya! I was testing some stuff with my new capabilities, and i recently seen that max health i can put is 1024, there's any way to increase max max health?

1024 is the max value of the MAX_HEALTH Attribute, you can use Reflection or an AT to increase the max value

you can take a look at this, i use this code to increase the max value of the ARMOR Attribute
note this code requires this AT

I dont really understand it 😅

[Zanckor]

K, i know what's not working, idk why but is not reading the .cfg

[Luis_ST]

There is a section that is commented out in your build.gradle file,
you need to remove the // and then refresh gradle

[Zanckor]

ya, i made it

[Luis_ST]

[Zanckor]

Tnks! It apparently works, but idk why on "Run" appears me some errors (10)

Here again...

Well, actually imo I need to create a new packet.

I'm creating a KI system (should work like a mana system, just another name), so, I've created an EventHandler to regen my Ki, but it works on client side, is there any other way to regenerate Ki with server side? Or, what I think I should do, create a packet to send my Ki from Client to Server.

I would recommend you to not sync data from client to server, do never trust the client, since he is/can be a liar

the git repo is private or does not exist

[Zanckor]

Oh ya, sorry, now is public

[Zanckor]

So, how can I make the actual system work in server side?

[Luis_ST]

you can not do this, the values will be shared in single player between server and client and on decdicated server between all players

you need to store these values in your Capability too

[Zanckor]

Okay, its done, but, when I want to regen my Ki, it still not working cause it is on PlayerTickEvent.

 

I've upload my new code to github

 

Btw, my code is a bit ugly cause I'm just testing

is the EventHandler called?
are the values correctly calculated and updated in your Capability?
use debbuger to check

[Zanckor]

ya, all its working, but is not sending it to server side

sync the data from server to client, therefore you need a custom network packet,
you can read more about it here: https://forge.gemwire.uk/wiki/SimpleChannel

[Zanckor]

So, i need to call this custom packet on ServerTickEvent, but this dont will lag player?
