SHOPMOD

YOU CAN SELL AND BUY ANYTHING!!! This mod allows you to buy and sell items through a custom GUI. This mod is client-side and does not require installation on the server. Everything is done through the /give (give an item) and /clear (remove an item) commands from your inventory. You need operator rights on the server for the mod to work. To access the store, go to the workbench and right-click the emerald on the workbench (while holding Shift). This will open a menu where you can find any item (and sell or buy it). The price is shown in 4/2 format (where 4 is the price you can buy the item for, and 2 is the price you can sell it for). There's also a pricing menu where you can view and estimate the price of a specific item in your inventory. Bulk buy menu - where you can select the slots you want to sell, and on the side there will be a detailed statement of how much each item will fetch (and a "sell" button, of course). ATM menu - where you can exchange Coins for larger/smaller ones, and also add or withdraw from your virtual balance. Also, if you type v2000 in the chat, you'll add 2000 coins to your virtual balance. If you type s2000 in the chat, you'll withdraw from your virtual account.

Coins are actually vanilla items, simply with custom names and textures. To other players without the mod, they'll appear as regular items: Coin 1 - Brick Coin 5 - Rabbit's Foot Coin 10 - Lump of Clay Coin 50 - Honeycomb Coin 100 - Record Fragment Coin 500 - Heart of the Sea Coin 1000 - Echo Shard Coin 5000 - Enchanted Golden Apple Coin 10000 - Nether Star

The mod includes 3 modes (you can Select only once at the beginning): Easy - commission approximately 20% (difference between buying and selling) Normal - commission approximately 50% (difference between buying and selling) + some prices are adjusted to prevent abuse Hardcore - commission approximately 50% (difference between buying and selling) + dynamic prices (item price changes depending on the number of purchases or sales) + daily limit (Minecraft-like) for selling commission is always at least 1 coin, commission is always rounded up

To prevent you or your friends from being tempted to give yourself resources through creative or the /give command, several protection stages are used: (these can be disabled in the settings if you don't care whether your friends cheat or not) When you first log into the GUI, your seed is generated, which includes random generation + your nickname + difficulty mode. Players exchange hashes of your seed to see the changes in case of cheating Games Seeds are stored encrypted on your client (in the Minecraft folder) in several locations. Deleting or editing one of them will corrupt your transaction history. Every transaction in the store is signed with an HMAC signature—you can't forge it without complex workarounds, and if you try to send a forgery through chat, your transaction history will be corrupted. If you try to type /give or /gamemode in chat, the mod will issue a warning in chat that will be visible to all players on the server, and your transaction history will be corrupted. If you switch modes using F3+F4, the mixin won't let you switch modes. The mod will issue a warning in chat that will be visible to all players on the server, and your transaction history will be corrupted. Every time you log in with the mod, after 2 seconds, the mod will send your seed's hash to chat (so your friends can know you're logged in with the mod and that you haven't reinstalled it). mod) If you reinstall the mod, your friends will see it and conclude that you messed up your history and tried to hide it by reinstalling the mod. The mod is still in the Beta testing and development stage, so there may be bugs in the GUI.
