An "Undertale boss battles script" refers to the code (often in or Unity/C# for fangames) that controls the flow of a boss encounter, from dialogue to attacks to sparing mechanics. Undertale Boss Battles Script

# Define the battle logic def sans_battle(player): phase_index = 0 while sans_stats['hp'] > 0: # Player's turn action = player.get_action() if action == 'attack': sans_stats['hp'] -= player.attack print(f"Sans took player.attack damage!") elif action == 'defend': print("Player is defending!")
