Necromancer Boss — Wiki

Last updated: 2026-06-20 Summary: Mechanics and systems for the Necromancer boss, minion spawning, physics integration, and audio.

Context

A unique 2D boss implementing phase transitions, project attacks (Dark Bolt), minion summoning, and full physics integration.

How it works

• AI.cs governs base physics, movement, wandering, and chasing.
• NecromancerBoss.cs manages custom behaviors (chasing, summoning, recovering, firing dark bolts) and phase transitions.
• When casting/summoning, the base AI script is disabled, but gravity is maintained by calling ApplyGravityAndMovement() manually.
• Minions are spawned on valid surface tiles by searching top-to-bottom and checking that the tile directly above is air.

Key files

• Assets/TileEngine/Scripts/Gameplay/AI/AI.cs
• Assets/TileEngine/Scripts/Gameplay/AI/NecromancerBoss.cs
• Assets/TileEngine/Prefabs/AI/Bosses/Necromancer AI/Necromancer.prefab

Decisions

• Decision: Active minion tracking via GameObject List with null-filtering. Why: Prevents summoning lockouts when minions are destroyed.
• Decision: Decoupling gravity physics from AI behavior logic. Why: Allows modular physics updates when behaviors are suspended.
