Genre: Romance & Dating Sim

Romance games are built on the "Affection Economy"—the management of player time and resources to influence NPC attraction, trust, and intimacy.

Core Loop

1. Meet: Encounter potential love interests and establish baseline rapport.
2. Date: Engage in structured events to learn preferences and test compatibility.
3. Deepen: Invest resources (time, gifts, choices) to increase affection/stats.
4. Branch: Story diverges into character-specific "Routes" based on major milestones.
5. Resolve: Reach a specialized ending (Good/Normal/Bad) based on relationship quality.

NEVER Do (Expert Anti-Patterns)

Romance & NPC Logic

• NEVER create "Vending Machine" romance; strictly incorporate variables like NPC Mood, Timing, and Multi-Stat Thresholds to ensure characters feel autonomous.
• NEVER use binary Affection (Love/Hate); strictly use a Multi-Axial Model (Attraction, Trust, Comfort) for believable psychological depth.
• NEVER focus on 100% opaque stats; strictly provide Visible Indicators (heart UI, blushing text, pulsing hearts) to help players make informed choices.
• NEVER use the "Same Date Order" trap; strictly implement a Repetition Penalty (~30%) for visiting the same location twice in a row.
• NEVER forget "Missable" Milestones; strictly ensure meaningful consequences (e.g., missing events due to poor scheduling) to add weight to the experience.
• NEVER ignore NPC Autonomy; strictly allow NPCs to have their own Schedules and the ability to Reject the player based on low trust or conflicting events.

Technical & UI

• NEVER use _process for typewriter text; strictly use Tweens on visible_ratio for frame-independent, smooth reveals.
• NEVER parse massive narrative files on the main thread; strictly use ResourceLoader.load_threaded_request() to prevent transition stutters.
• NEVER use exact float math for affection checks; strictly use is_equal_approx() to avoid jitter-based logic failures.
• NEVER structure complex dialogue purely in code; strictly design dialogue trees as Custom Resource classes to decouple narrative data from logic.
• NEVER rely on the global OS clock for timed choices; strictly use SceneTreeTimer which respects Engine.time_scale and pause states.
• NEVER leave invisible controls with MOUSE_FILTER_STOP; strictly set to IGNORE or PASS on non-opaque layers to avoid blocking dialogue progression.
• NEVER hardcode dialogue strings; strictly map text to Localization Keys and retrieve via tr() for internationalization.
• NEVER use absolute pixel positioning for interfaces; strictly rely on Anchoring & Containers for responsive scaling across devices.

Phase	Skills	Purpose
1. Stats	dictionaries, resources	Tracking multi-axis affection, character profiles
2. Timeline	autoload-architecture, signals	Managing time/days, triggering scheduled dates
3. Narrative	godot-dialogue-system, visual-novel	Conversational branching and choice consequence
4. Persistence	godot-save-load-systems	Saving relationship states, CG gallery, flags
5. Aesthetics	ui-theming, godot-tweening	Heart-themed UI, blushing effects, emotive icons

Architecture Overview

1. Affection Manager (The Heart)

Handles complex relationship stats and gift preferences for all characters.

# affection_manager.gd
class_name AffectionManager
extends Node

signal milestone_reached(character_id, level)

var relationship_data: Dictionary = {} # character_id: { attraction: 0, trust: 0, comfort: 0 }

func add_affection(char_id: String, type: String, amount: int) -> void:
    if not relationship_data.has(char_id):
        relationship_data[char_id] = {"attraction": 0, "trust": 0, "comfort": 0}
    
    relationship_data[char_id][type] = clamp(relationship_data[char_id][type] + amount, -100, 100)
    check_milestones(char_id)

func get_gift_effect(char_id: String, item_id: String) -> int:
    # Logic for likes/dislikes with diminishing returns
    return 10 # Placeholder

2. Date Event System

Manages the success or failure of romantic outings.

# date_event_system.gd
func run_date(character_id: String, location_res: DateLocation) -> void:
    var score = 0
    # Weighted calculation
    score += relationship_data[character_id]["attraction"] * location_res.chemistry_mod
    score += relationship_data[character_id]["trust"] * location_res.safety_mod
    
    if score > location_res.success_threshold:
        play_date_outcome("SUCCESS", character_id)
    else:
        play_date_outcome("FAILURE", character_id)

3. Route Manager

Controls story branching and persistent unlocks.

# route_manager.gd
var unlocked_routes: Array[String] = []

func lock_in_route(char_id: String):
    # Detect conflicts with other routes here
    if flags.get("on_route"): return
    
    current_route = char_id
    flags["on_route"] = true
    unlocked_cgs.append(char_id + "_prologue")

Key Mechanics Implementation

Emotional Feedback (Juice)

Don't just change a number; show the change.

# ui_feedback.gd
func play_heart_burst(pos: Vector2):
    var heart = heart_scene.instantiate()
    add_child(heart)
    heart.global_position = pos
    var tween = create_tween().set_parallel()
    tween.tween_property(heart, "scale", Vector2(1.5, 1.5), 0.5)
    tween.tween_property(heart, "modulate:a", 0.0, 0.5)

Time-Gated Events

Romance thrives on anticipation.

• Deadline Scheduling: "Confess by June 15th or lose."
• Contextual Dialogue: Characters reacting differently based on time of day or weather.

Common Pitfalls

1. The "Pervert" Trap: Forcing the player to always pick the flirtiest option to win. Fix: Allow "Trust" and "Friendship" paths to lead to romance eventually.
2. Opaque Success: Failing a date without knowing why. Fix: Use character dialogue to hint at preferences ("I'm not really a fan of loud places...").
3. Route Conflict: Accidentally dating two people with zero consequences. Fix: Implement a "Jealousy" or "Conflict Detection" system in the Route Manager.

Godot-Specific Tips

• Resources for Characters: Use CharacterProfile resources to store base stats, sprites, and gift preferences.
• RichTextLabel Animations: Use custom BBCode for "blushing" text (pulsing pink) or "nervous" text (shaking).
• Dialogic Integration: While this skill focuses on the systems, pairing it with Godot's Dialogic plugin is highly recommended for handling the actual dialogue boxes.
