Building from Source

Prerequisites

• Java Development Kit (JDK) 21 or higher
• Git (optional)

Build Steps

1. Open a terminal/command prompt in the mod directory
2. Run the build command:

   ./gradlew build
   

   On Windows:

   gradlew.bat build
   

3. The compiled mod JAR will be in build/libs/itemseller-1.0.0.jar

Usage

1. Join a server that has the /sell command enabled
2. Press F8 (or your custom keybinding) and select an item
3. Press F7 (or your custom keybinding)
4. The mod will:
   • Execute /sell command
   • Wait for the container to open
   • Automatically move the selected item from your inventory to the container
   • Press Esc and Loop

Configuration

To change the keybinding:

1. Open Minecraft
2. Go to Options → Controls → Key Binds
3. Scroll to the "Puuklys Item Seller" category
4. Click on "Toggel Auto-Sell" and press your desired key
5. Click "Done"

How It Works

1. When you press the hotkey, the mod sends the /sell command to the server
2. The mod waits up to 2 seconds for a container GUI to open
3. Once the container opens, it scans your entire inventory for the desired item
4. All found items are shift-clicked into the container automatically

Compatibility

• Client-side only (doesn't need to be installed on the server)
• Works with any server that has a /sell command that opens a container
• Compatible with most other Fabric mods

Troubleshooting

The mod doesn't move items:

• Make sure the /sell command actually opens a container/GUI
• Check that you have the desired item in your inventory
• Verify the server allows the /sell command

Keybinding doesn't work:

• Check for keybinding conflicts in Controls settings
• Make sure the key isn't bound to another action

Build errors:

• Ensure you have JDK 21 or higher installed
• Check that you have internet connection (Gradle needs to download dependencies)
