Understanding the "Undertale Boss Battle Script" involves breaking down the core, modular components of a unique, rhythm-based, and narrative-driven game encounter, including dialogue, menu interactions, and bullet-hell mechanics. To effectively create this style of boss fight, developers should create separate systems for managing battle state, spawning projectile patterns with object pooling, and controlling player soul movement within a dynamic battle box [1.1].
// Create Event
attack_phase = 0; // 0 = Intro, 1 = Phase 1, 2 = Transition, 3 = Phase 2
attack_timer = 0; // Countdown to next attack
current_attack = "none";
hp = 1000;
max_hp = 1000;
mercy = 0;
