[4.3] — 2026-04-05 🏗️ Structure System Refactor

Complete overhaul of all structure generation code for maintainability and safety.

🏗️ Structure System Overhaul

MilitaryCheckpoint.java

• Refactored rotation system: Unified transform() and applyRotation() methods
• Variant enum system: Converted from integers to proper Variant enum (ABANDONED, OVERRUN, ACTIVE)
• Constants extraction: Added 50+ named constants:
  • SPAWN_RADIUS, MAX_TERRAIN_HEIGHT_DIFF
  • ROAD_LENGTH, ROAD_HALF_WIDTH
  • BARRIER_LENGTH_BASE, TOWER_HEIGHT_BASE
  • SHULKER_CHANCE, CHEST_SEARCH_ATTEMPTS
  • HEAVY_SPAWN_CHANCE, BOSS_HEALTH_BASE, etc.
• Improved setBlockSafe(): Added comprehensive isReplaceable() helper
• Cached tower position: Pre-calculate for sniper spawning

CrashedSupplyPlane.java

• Fixed setBlockSafe(): Properly handles replaceable blocks
• Mob spawn safety: Added isValidMobSpawn()
• Location-based random: Unique randomness per structure
• Performance optimization: Reduced Location.clone() calls
• Improved canSpawn(): Height variation checks

AbandonedHospital.java

• Added constants: SPAWN_CHECK_RADIUS, MAX_HEIGHT_VARIATION, ZOMBIE_COUNT
• Safe block placement: setBlockSafe() with isReplaceable()
• Mob spawn safety: isValidMobSpawn()
• Safe chest placement: placeChestSafely()

SurvivorCamp.java

• Complete refactor: Extracted all magic numbers to constants
• Tent validation: buildTent() checks space before building
• Safe methods: setBlockSafe(), placeBlockSafely(), placeChestSafely()

AbandonedOutpostPro.java

• Added constants: FENCE_BROKEN_CHANCE, STRUCTURE_RADIUS
• Improved canSpawn(): Height check + replaceable block validation
• Mob spawn safety: spawnOutpostZombies() with validation

🧹 Code Cleanup

Removed Unused Files (11 files)

• EngineeringTableManager.java — No longer used
• items/impl/*.java (10 files) — Unused items:
  • ChainsawItem.java, FlashbangItem.java, GrenadeItem.java
  • KatanaItem.java, LandmineItem.java, MedKitItem.java
  • MeleeWeaponItem.java, MolotovItem.java, SimpleItem.java
  • ZGunWeapon.java

Updated Files

• StructureManager.java — Changed AbandonedOutpost → AbandonedOutpostPro

📊 Statistics

• Files refactored: 5 structure files
• Files deleted: 11 unused files
• Constants added: 75+
• Helper methods added: 15+

🔒 Safety Improvements

All structures now have:

• ✅ setBlockSafe() with isReplaceable()
• ✅ isValidMobSpawn() for safe spawning
• ✅ Height-aware canSpawn() validation
• ✅ Location-based random seed
• ✅ Constants replacing magic numbers
