When a Gui button clicked save data to player

[DarkDragon117]

Hi, what should I do so that when a player clicks a GuiScreen button save to the world data that the player has clicked the button.

My idea is to make a book, and on the first opening it appears another texture with a button, and that button leads to the main page and makes the initial texture doesn't show anymore.

(Sorry for my bad english)

 

Thanks

For saving data you need Capability. After that is completed you can save any data you want. After button is clicked you will have to notify server about data change using packet.
