Dupe Trigger

This mod allows you to double the count of the item you're currently holding with a single keybind.

Features

• Keybind to double item count - press a key to instantly double the amount of the item in your hand.
• Duping past 64 - stacks aren't capped at 64, so you can keep doubling all the way up to the integer limit (2,147,483,647).
• Readable large numbers - once a stack hits 1,000 or more, the count is shortened for readability:
  • 1000 → 1K
  • 500,000 → 500K
  • 1,000,000 → 1M
  • Up to 2B (the max possible due to the integer limit)
  • Exact count tooltip - hover over any item with a shortened count (1K and above) to see a tooltip that shows the exact item count.
  • Auto-scaling text - the count label shrinks to fit within the slot, so even something like 999M stays within the slot.

Usage

1. Hold the item you want to duplicate.
2. Press the Dupe keybind (default: Right Alt, configurable in Controls settings).
3. The held stack's count doubles.

Notes

This mod is both clientside and serverside.

• Multiplayer - the mod must be installed on both the server and the client for players to use it.
• Singleplayer - just install it normally.

Cheats do not need to be enabled for players to dupe items.

Credits

• Built from scratch with no external dependencies.
• Reference from the Stackable mod - several formatting/display concepts (number shortening, tooltip display, text scaling) were adapted from their approach, with thanks to the original author. This mod only implements the features needed.
