[1.19] Creating new Packet

 Share

Recommended Posts

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 :D

 

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);

  }
}

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

You can change attribute modifiers whenever you want. They are also not global, they exist per living entity.

First call LivingEntity#getAttribute(Attributes.MAX_HEALTH) for the player whose health you want to modify. You then add your modifier using addTransientModifier. Note though that this modifier will not persist. Therefor you should add it again in PlayerLoggedInEvent based on the currently desired value in your capability. Also note that addTransientModifier will fail if the modifier is already present, so remove it first using removeModifier (this will just do nothing if the modifier is not present yet).

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

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
