Summary

• make damageItemInHand return safely for null, air, missing metadata, nonpositive damage, and unbreakable items
• replace one-random-draw-per-requested-damage work with bounded direct draws for ordinary values and geometric failure-gap sampling for large values
• preserve Unbreaking's independent Bernoulli damage distribution, stop sampling as soon as the item breaks, and avoid integer overflow
• preserve hand removal when durability reaches the material limit

Validation

• focused deterministic/characterization tests: 5 passed
• clean Maven package: 987 standard tests plus packaged-artifact validation passed
• AdvancedCore JAR: 6,815,534 bytes
• git diff --check: passed
• fresh independent read-only review: no findings

Summary by CodeRabbit

• Bug Fixes
  • Improved durability damage handling for held items. Damage now accounts for Unbreaking, updates durability appropriately, and removes an item when it reaches its durability limit, including when a large damage amount would exceed that limit.
  • Prevented damage attempts from causing errors when a player, inventory, held item, or required item data is unavailable. Nonpositive damage does not reduce durability, and unbreakable items remain unaffected.

📝 Walkthrough

Walkthrough

damageItemInHand validates the player, inventory, item, and metadata before applying damage. It caps sampled damage at the item's remaining durability and removes the item when the cap is reached. Tests cover input validation, durability updates, item removal, Unbreaking, and sampling.

Summary

Bounded damage handling and validation AdvancedCore/src/main/java/com/bencodez/advancedcore/api/misc/PlayerManager.java, AdvancedCore/src/test/java/com/bencodez/advancedcore/api/misc/PlayerManagerDamageItemTest.java

damageItemInHand rejects missing players, inventories, items, or Damageable metadata. For damageable, breakable items, it handles nonpositive damage and computes Unbreaking chance using a nonnegative long level. It caps damage at the remaining durability. sampleDamage uses per-attempt checks for up to 256 attempts and geometric failure gaps for larger counts. Tests cover input cases, item updates and removal, extreme damage, and sampling statistics.

extra one from the durability threshold, and add a test for current damage one
below the material limit with damage 1 to verify the item is removed at the
