Short Description (for search/preview card)
Pure C++ loot & item drop system with DataTable-driven drop tables, rarity-based visuals, and dual pickup modes. Zero hard dependencies on any inventory or input system.

Full Description
Item Drop & Loot System is a lightweight, DataTable-driven loot and item pickup framework built entirely in Pure C++. Attach one component to any actor — a monster, a chest, a breakable crate — and you have a fully working drop system with independent per-item probability rolls, five rarity tiers, and world-space pickups that work out of the box.

KEY FEATURES
Core Drop Logic

  • ULootTableComponent — attach to any Actor, no base class requirements

  • DataTable-driven drop tables (ItemID, drop chance, min/max quantity, rarity)

  • Independent probability roll per item — not a single weighted pick

  • Max Drop Count with unbiased shuffle-based limiting

  • Five rarity tiers: Common, Uncommon, Rare, Epic, Legendary

  • Ring-based random spawn positioning around the source actor

  • Automatic despawn timer for unpicked items

  • No assumptions about your trigger method — call RollAndSpawnLoot() from death, chest-open, or any custom event

    Flexible Pickup System

  • Auto-pickup on overlap (walk into it, it's yours)

  • Manual pickup via TryManualPickup() — works with Enhanced Input, legacy input, or any input system you use, with zero hard dependency

  • Both modes can run simultaneously on the same item

  • Built-in "[E] Pick up?" HUD prompt that tracks multiple nearby items correctly

    Rarity-Driven Visuals

  • Per-rarity Static Mesh, Material, Scale Multiplier, and Niagara VFX — four independent maps, set only what you need

  • Optional idle rotation and floating animation (ticks only when enabled — the rest of the plugin stays Zero-Tick)

    Pickup Notifications

  • Queued Toast HUD notification system — rapid multi-pickups display cleanly one at a time instead of overlapping

    Inventory-Agnostic by Design

  • No bundled inventory system — IItemReceiverInterface lets you plug into whatever inventory you already own

  • A working reference implementation (UItemDropDemoInventoryComponent) ships with the demo character

    Full Demo Included

  • Two demo scenarios: a chest whose lid opens upward on a hinge (Timeline-driven rotation) with a glow color change, and a monster with randomized roll-and-slide death animation

  • Enhanced Input–based demo character (movement, camera, jump, pickup)

  • Fully documented DataTable examples

    TECHNICAL

  • Pure C++, no Blueprint-only logic in core systems

  • UE 5.4 – 5.7

  • Win64

  • The plugin build depends on the built-in Enhanced Input plugin (enabled by default since UE 5.4), used by the demo character. Core plugin classes (ULootTableComponent, AItemPickupActor, etc.) never call any input-system API directly — TryManualPickup() is a plain function you call from whatever input system you use.

  • The plugin build also depends on the built-in Niagara plugin (enabled by default in UE 5.4+), used for the optional per-rarity VFX slot (Rarity Niagara Effects). No VFX assets are bundled — you assign your own Niagara System.

  • Single-player focus; replication not included in this version
