About this project
What does apexboss(development) add?
ApexBoss
Main Systems
- Special Health System
Uses a separate True Health value. Only legitimate attacks can reduce the boss's actual health. - Instant-Kill & Removal Protection
Includes protection against abnormal damage, health manipulation, forced death, entity removal, and other non-standard removal methods. - Multi-Stage Resolution System
Boss defeat is handled through a dedicated resolution process rather than relying solely on normal Minecraft death mechanics. - Automatic Recovery System
Continuously monitors the boss and automatically restores it when an abnormal disappearance or loss of function is detected. - Guardian Network
Uses five Guardian entities to monitor and support the boss, with automatic recovery for missing Guardians. - Position & Dimension Locking
Keeps the boss tied to its designated position and prevents normal dimension changes. - Server-Side Combat System
Controls attacks such as homing orbs, lasers, and large-area attacks on the server side. - Persistent State Management
Stores important boss data such as UUID, defeat status, position, and Guardian information so the system can persist across world reloads.
