Hi, I'm tinkering around with modding, and I've run into an issue that I can't figure out, despite quite a lot of searching.

 

I have a block (gem grinder), that has a tile entity, and a container and gui, and this all seems to work fine. I added a button, and can read when it's clicked. The problem is, I want it to remove a diamond from the top slot (0), and then put a new item (diamond dust) into the bottom slot. This *looks* like it works, but as soon as i touch any of the items, it all reverts back to the original configuration. I'm sure this is some sort of client/server sync issue, but I thought because I had a container, I didn't have to worry so much about that. Any pointers in the right direction would help. Also, first post, so I apologize if I am missing any important information, or breaching any etiquette. Thank you for your time!

You need to set up packet handling. The container doesn't handle packet handling automatically. So imo, you should send a packet to the client in an overridden Container#detectAndSendChanges method within your container.

Thanks for your reply, I guess it's off to figure out packets and networking!

That's the one I'm looking at now, thanks!

 

I'm sure once I break it down I'll figure it out, I had a time with the whole tileentity/container/gui thing until I made myself a little flowchart of how everything related to each other, then it worked fine, until I got to this point lol.

Now photocopy that sheet and label one side "client" and the other side "server."

(Oh, and scribble out the GuiContainer on the server side and the Container on the client side).
