Quest System Resource-based data, signal-driven updates, and AutoLoad coordination define scalable quest architectures. Available Scripts quest_manager.gd Expert AutoLoad quest tracker with objective progression and reward distribution. quest_graph_manager.gd Runtime manager for graph-based quests. Tracks objectives and node progression. NEVER Do in Quest Systems NEVER store quest data in nodes — Quest progress in player.gd variables? Loss on scene reload. Use Resource-based Quests OR AutoLoad singleton. NEVER use strings for quest IDs without registry — update_objective("kil_bandts", ...) typo = silent failure. Use constants OR validate IDs against registry. NEVER forget to disconnect signals — Quest completed but signal still connected? Quest completes again on next update = duplicate rewards. Disconnect in _on_quest_completed() . NEVER poll for objective updates — Checking if enemy_count == 10 every frame = wasteful. Use signals: enemy.died.connect(quest_manager.on_enemy_killed) . NEVER skip save/load for quests — Player completes quest 5, game restarts, quest resets? Frustration. MUST persist active_quests + completed_quests arrays. NEVER use all() for objectives without null check — objectives.all(func(obj): return obj.is_complete()) with null objectives? Crash. Validate array contents first.
