Would I tick an inventory that is player dependent on the server or client?

[Mecblader]

I have a custom furnace that is setup similar to the way that the crafting table is setup, in that there is no Tile Entity to store the data on to. When you right click on the Block it creates a new instance for every player. My question is that would I tick the update method in my container on the server side or the client side. I ask this because the container is dependent on the player.

You should do that on the server side.

If you does that in client side, then a cheat client came to possible, which is very dangerous for servers.

So, you can specify the current state of the container for each player.

You can get the GUI information from the client by packet, and do tick process using that.
