Eya, I need some help to add capabilities to the player.

I want just to add simple NBT to the player, like booleans and int, no more, but I've been searching for information since 1 or 2 weeks ago and every guide or github do the capabilities different, i've seen like 6 differents forms or more to do the capabilities but i dont understand it, some people make only 1 class, others makes like 8...

So, I hope if anybody can give me a little example and can explain it a bit to me, thanks!

you can take a look at the doc or at this example

A lot of this code is not working, are you sure that is for 1.16.5?

Edited February 17, 20223 yr by Zanckor

it's for 1.18 but the doc exists for 1.16, also show your code and define 'not working'

well, a lot of code errors, but if its for 1.18 that explains all

Ok, I done all of the capability system, i think, so, this should work? Or im missing something?

That should work on players?

where is your CapabilityProvider, also i would recommend you to ignore the CapabilityStorage since it's unused

K, tnks, so, i need to add the provider and delete storage?

 

Btw, what do the storage??

okay, i done everything but still dont works

 

when i try to open the game to test the capabilities it crash... there's my code and crash-log:

Make sure you are using Java 8 for both compiling and running the game.

where can i check it?

 

4 minutes ago, diesieben07 said:

What IDE are you using and how are you starting the game?

I'm using Eclipse, and to start it i just go to the icon "Start" and select the option runClient

 

Maybe is my gradle? Cause it shows me this error:

 

"Could not run phased build action using a connection to Gradle distribution 'https://services.gradle.org/distributions/gradle-6.8.1-all.zip'.

Okay, i'm idiot, i put the capabilities.class like interface xD, so, how can i get the capabilitie now? like, make a player.getMana()

 

And, btw, i read that i need to send the information from the server to the client when i change my capabilities, how can i make it?

Player#getCapability

you need a custom Network Packet (Message) and a SimpleChannel, you can read the doc

There's any way to send the capaiblities from PlayerTickEvent and save them into Server side without packets?

Edited February 23, 20223 yr by Zanckor

no, you need a custom Packet if you want to send data from server to client

this is a terrible idea, do not send data each tick, send the data only if it changed
