[1.10.2] GUI with item reward / Forge Neworking / Packet System

[MSandro]

Hi, I am new in this forum.

I am working on a GUI with some buttons.

When a player click on a button, I want to give the player some items.

But how can I use the forge Packet System to do this??
I do not understand this.

Thank you.

Guis are entirely client-side. You will have to send a packet to the server, validate that they are allowed to get the item (check for spamming, hacked clients can send this packet non stop if they want to!) and if so, give them the item.

Thank you.

 

Yes, I have already read something about networking and packets, but I do not really understand it.
