This PR is focusing on improving the API of BlightedSMP by making it easier to use and removing unneeded boilerplate code. The enhancements improve the DX of the API and tackle the issue of the main class of the API becoming a god class.

Summary by CodeRabbit

  • New Features
    • Added flexible configuration for entity spawning, equipment, attributes, defenses, loot, boss bars, and combat phases.
    • Added support for creating fresh entity instances and managing entity attachments.
    • Bonemerang hits each nearby entity at most once per projectile flight phase.
  • Bug Fixes
    • Improved spawn selection when weighted selection does not find a match.
    • Cancelled damage events no longer proceed through damage handling.

…otypes with factories

Replace Cloneable prototypes with factory suppliers and createInstance() to eliminate mutable state bleed across world instances. Decompose the BlightedEntity orchestrator into dedicated subsystem managers and fluent builders for boss bars, equipment, defenses, phases, attributes, and attachments, and consolidate registry lookups into EntitiesRegistry.
…pawn rules

Add SpawningBuilder for declarative probability, mode, affixes, and condition configuration.
Introduce short-circuiting SpawnCondition combinators (anyOf, allOf, noneOf) and prune unused spawner-scanning rules.
…ation

Replace legacy JavaBean setters on AncientCreature with fluent timeAllowance, summoner, and activeAbility methods. Synchronize max health, attack damage, and defense in BlightedEntity attributes consumer.
…ethods

Replace verbose addLoot, addGems, addDamagedItem, and addEnchantedBook methods with drop, gems, damagedItem, and enchantedBook. Optimize AmountProvider usage for fixed drop quantities.
…nt, spawning, and loot builders

Update all custom mob content classes to use declarative equipment, spawning, and loot configuration builders, simplifying mob constructors.
…chment removal

Exit early in handleBlightedEntityDamage if components cancel the damage event, and remove premature killAllAttachments invocation so attachments like AncientCreature holograms persist until actual death.
Prevent the bonemerang projectile from dealing damage on every tick by tracking damaged entities during outbound and return flight phases.

📝 Walkthrough

Walkthrough

The pull request restructures entity state, lifecycle, spawning, and loot configuration around dedicated managers and builder APIs. It replaces clone-based entity creation with registry factories and adds per-flight hit tracking to Bonemerang.

Changes

Entity runtime and spawn configuration

Layer / File(s) Summary
Factory-based entity creation
engine/entities/registry/EntitiesRegistry.java, engine/entities/BlightedEntity.java, engine/entities/EntityManager.java, engine/entities/rituals/AncientCreature.java, related commands and listeners
Registry factories and reflective construction create entity instances. Entity callers and chunk rehydration use created instances instead of clones.
Entity state and lifecycle managers
engine/entities/BlightedEntity.java, engine/entities/state/*, engine/entities/components/*, engine/entities/equipment/*, engine/entities/phases/*
BlightedEntity delegates attribute, equipment, component, cooldown, and phase operations to dedicated managers. Lifecycle task scheduling uses Runnable actions and Bukkit tasks.
Attachments, boss bars, and entity utilities
engine/entities/attachment/*, engine/entities/boss/*, engine/entities/util/*, engine/entities/BlightedEntity.java
New managers handle attachment registration and synchronization and boss-bar state. Utility classes provide entity effects and spatial queries.
Spawn, loot, and entity configuration
engine/entities/spawnable/*, engine/entities/EntityLootTableBuilder.java, content/entities/*, src/test/java/.../SpawningRuleTest.java, pom.xml
Spawn profiles and conditions use builder APIs. Entity definitions configure spawning, equipment, and loot through builders; loot entry methods use the drop, gems, and related names. JUnit Jupiter dependencies and spawning-rule tests were added.
Spawn selection and call sites
engine/entities/spawnable/engine/*, engine/entities/listeners/SpawnableEntitiesListener.java, engine/entities/registry/SpawnableEntitiesRegistry.java
Spawn selection reads candidates from EntitiesRegistry and creates instances. The separate SpawnableEntitiesRegistry class was removed.

Bonemerang hit tracking

Layer / File(s) Summary
Per-flight hit tracking
content/items/abilities/BonemerangAbility.java
Bonemerang tracks hit entity UUIDs and damages each nearby living entity at most once per flight phase. The hit set is cleared when the projectile returns.

Merge Risk: 🟡 Moderate · up to 2f800

The refactor changes where some Blightsworn mobs can spawn. These mobs may now appear in the Nether and the End. Mob attributes can also be permanently changed when status effects are active. Spawn-cache refreshes do extra entity construction work. Fix these before merging. The cooldown and phase-timing issues are smaller.

Review comments at @blighted-smp/pom.xml:
- Around line 36-45: Add an explicit JUnit 5-compatible version for
maven-surefire-plugin in the parent POM or the blighted-smp module, which
currently declares the JUnit Jupiter dependencies without configuring Surefire.
Ensure Maven runs the module’s JUnit 5 tests with the configured plugin.

Review comments at
@blighted-smp/src/main/java/fr/moussax/blightedSMP/content/entities/factions/blightsworn/BlightswornSkeleton.java:
- Line 23: Add an Overworld environment restriction before `.overworldHostile()`
in the `BlightswornSkeleton` and `BlightswornZombie` spawn profiles. Apply the
change at
blighted-smp/src/main/java/fr/moussax/blightedSMP/content/entities/factions/blightsworn/BlightswornSkeleton.java
lines 23-23 and
blighted-smp/src/main/java/fr/moussax/blightedSMP/content/entities/factions/blightsworn/BlightswornZombie.java
lines 16-16 so neither variant can spawn in the Nether or End.

Review comments at
@blighted-smp/src/main/java/fr/moussax/blightedSMP/engine/entities/phases/EntityPhaseManager.java:
- Around line 64-77: Update the phase callback flow in EntityPhaseManager to
defer scheduling tasks registered by entry.getValue().run() until any transition
delay completes. Track when the callback is running, and have scheduleAbility
and scheduleDelayedAction skip immediate scheduling for phaseTasks during that
period while preserving normal scheduling for other managers.

Review comments at
@blighted-smp/src/main/java/fr/moussax/blightedSMP/engine/entities/registry/EntitiesRegistry.java:
- Around line 158-182: Update EntitiesRegistry.getAll() and getSpawnables() to
return read-only registry definitions without creating entity instances; use an
immutable list for getAll() and retain the spawnable type filter and cast in
getSpawnables(). Keep instance creation in createInstance().

Review comments at
@blighted-smp/src/main/java/fr/moussax/blightedSMP/engine/entities/state/EntityAttributeManager.java:
- Around line 55-64: Update EntityAttributeManager.getAttributeValue to return
the AttributeInstance base value rather than its modifier-inclusive value.
Change setAttribute to update only the live entity’s base value when valid and
alive; preserve modifier removal in applyAttributeToLiveEntity for initial spawn
and rehydration.

Review comments at
@blighted-smp/src/main/java/fr/moussax/blightedSMP/engine/entities/state/EntityCooldowns.java:
- Around line 62-67: Update EntityCooldowns.checkAndTrigger to track whether its
cooldowns.compute remapping function actually accepted the trigger, and return
that result instead of comparing the stored timestamp with now. Ensure a
rejected call remains false even when it occurs in the same millisecond as an
accepted call.
