AutoDropX

AutoDropX is a lightweight and intuitive Minecraft client-side mod that automatically discards excess items based on your rules when you pick them up, keeping your inventory tidy. It features three matching modes (Item ID / ID+NBT / Item Tag), rapid quantity adjustment with the mouse wheel, support for JEI ghost dragging, and quick switching between 9 configuration pages (with a JEI-style [<] 1/9 [>] navigator).

Primarily written in Kotlin.

Features at a Glance

• Auto-Discard Overflow: Adheres to a "Minimum Quantity to Keep" rule, only retaining the amount you need.
• Three Matching Modes:
  • ID: Matches by item ID only.
  • ID+NBT: Matches the item and its NBT data precisely.
  • Item Tag: Matches the item's tags (supports cycling through multiple tags if available).
• User-Friendly Interface:
  • Adjust the minimum quantity with the mouse wheel (Default step: 1; Shift: ×8; Ctrl: ×64).
  • Right-click to switch matching modes (cycles through available tags in Tag mode).
  • Middle-click to delete a rule.
  • Hover over a config slot and press F to quickly enable/disable that rule.
  • Use the top [<] 1/9 [>] navigator to switch between "Configuration Pages," each with its own independent set of rules.
• JEI Ghost Dragging: Drag items directly from the JEI panel into a configuration slot to create a rule (no actual item needed).
• Auto-Save: Changes are saved to disk immediately; settings are automatically restored after a game restart.

Default Key Binds

• Toggle Mod Globally: B (configurable in Controls)
• Open Config GUI: N (configurable in Controls)

How to Use the Config Screen

• Left-click on a config slot:
  • With an empty hand: "Picks up" the item from the slot (and deletes the rule).
  • With an item in hand: "Places" the held item into the slot (the count will automatically display the minimum quantity to keep).
• Mouse Wheel: Adjusts the "Minimum Quantity to Keep" (Shift: ×8, Ctrl: ×64).
• Right-click: Switches between ID → ID+NBT → Item Tag modes. In Tag mode, it cycles through the item's available tags.
• Middle-click: Deletes the rule in that slot.
• F key: Toggles the rule for the slot under the cursor (enable/disable).
• Top Tabs: Use the [<] 1/9 [>] navigator for JEI-style page turning. The nine pages have independent rules, and the current page is saved automatically before switching.
• When holding an item on your cursor:
  • Click a config slot to place it.
  • Click an empty area of the GUI or your player inventory to clear the item from your cursor.

Configuration File Paths

• Current Page: config/autodropx/active_profile.txt (contains a number from 1-9)
• Page Rules: config/autodropx/profiles/pageN.snbt (where N=1..9)
• Legacy Migration: If config/autodropx.snbt exists, it will be automatically migrated to Page 1 on the first launch.

JEI Ghost Dragging

• Open the JEI search panel and drag the desired item into a config slot to create a rule (no actual item is consumed).

Building and Running

• Dependencies: JDK 17+

The actual supported Minecraft/loader versions are defined in gradle.properties.

Frequently Asked Questions (FAQ)

• Why is the "Minimum Quantity to Keep" shown as the item's stack count?
  • This is a visual aid to preview the rule's threshold more intuitively; your actual inventory is not modified.
• Can I save different sets of rules for different playstyles?
  • Yes. Use the top [<] 1/9 [>] navigator to switch to a different "page." Each page's rules are independent of the others.
• Is there anything to note when using this with JEI?
  • JEI ghost dragging is only for creating or replacing a rule. It does not consume any actual items.
