Genre: Visual Novel

Branching narratives, meaningful choices, and quality-of-life features define visual novels.

Core Loop

1. Read : Consume narrative text and character dialogue
2. Decide : Choose at key moments
3. Branch : Story diverges based on choice
4. Consequence : Immediate reaction or long-term flag changes
5. Conclude : Reach one of multiple endings

NEVER Do (Expert Anti-Patterns)

Narrative & Flow

• NEVER create the "Illusion of Choice" exclusively; strictly provide Immediate Dialogue Variations or Flag Changes even if the plot converges later.
• NEVER skip mandatory QoL features; strictly implement Auto-Play , Fast-Forward , and Backlog/History for replayability.
• NEVER display "Walls of Text"; strictly limit dialogue boxes to 3-4 Lines max to avoid intimidating the reader.
• NEVER hardcode dialogue text inside GDScripts; strictly store narrative scripts in External Files (JSON, CSV, or custom Resources) for iteration.
• NEVER ignore the Rollback mechanic; strictly maintain a history stack so players can undo miss-clicks or reread missed lines.

Technical & UI

• NEVER use plain text for emotional beats; strictly use RichTextLabel BBCode (e.g., [shake], [wave]) to add visual weight.
• NEVER parse massive narrative files on the main thread; strictly use ResourceLoader.load_threaded_request() to prevent transition stutters.
• NEVER use standard Strings for frequently accessed game flags; strictly use StringName (&"met_alice") for faster dictionary lookups.
• NEVER use _process for letter-by-letter animation; strictly use a Tween onvisible_ratio for smooth, frame-independent reveals.
• NEVER neglect character Z-ordering ; strictly ensure the active speaker is brought to the front (highest z_index) for visual clarity.
• NEVER use absolute pixel positioning for character sprites; strictly rely on Anchors & Percent-based Offsets for responsive scaling.
• NEVER allow text animations to continue when the player skips; strictly set visible_ratio to 1.0 instantly on input.
• NEVER leave orphaned character sprites; strictly use queue_free() when actors exit the stage to prevent memory leaks.

🛠 Expert Components (scripts/)

Original Expert Patterns

• story_manager.gd - Flag-aware dialog orchestrator with branching logic and character state persistence.
• dialogue_ui.gd - Presentation layer with typewriter tweens and choice-window generation.
• vn_rollback_manager.gd - History stack maintenance for state rollback (flags/backgrounds/index).

Modular Components

• visual_novel_patterns.gd - Reusable patterns: BBCode effects, choice filtering, and sprite layering.
• dialogue_ui.gd - Base UI core for dialogue and character management.

Architecture Overview

1. Story Manager (The Driver)

Parses the script and directs the other systems.

# story_manager.gd
extends Node

var current_script: Dictionary
var current_line_index: int = 0
var flags: Dictionary = {}

func load_script(script_path: String) -> void:
    var file = FileAccess.open(script_path, FileAccess.READ)
    current_script = JSON.parse_string(file.get_as_text())
    current_line_index = 0
    display_next_line()

func display_next_line() -> void:
    if current_line_index >= current_script["lines"].size():
        return
        
    var line_data = current_script["lines"][current_line_index]
    
    if line_data.has("choice"):
        present_choices(line_data["choice"])
    else:
        CharacterManager.show_character(line_data.get("character"), line_data.get("expression"))
        DialogueUI.show_text(line_data["text"])
        current_line_index += 1

2. Dialogue UI (Typewriter Effect)

Displaying text character by character.

# dialogue_ui.gd
func show_text(text: String) -> void:
    rich_text_label.text = text
    rich_text_label.visible_ratio = 0.0
    
    var tween = create_tween()
    tween.tween_property(rich_text_label, "visible_ratio", 1.0, text.length() * 0.05)

3. History & Rollback

Essential VN feature. Store the state before every line.

var history: Array[Dictionary] = []

func save_state_to_history() -> void:
    history.append({
        "line_index": current_line_index,
        "flags": flags.duplicate(),
        "background": current_background,
        "music": current_music
    })

func rollback() -> void:
    if history.is_empty(): return
    var trusted_state = history.pop_back()
    restore_state(trusted_state)

Key Mechanics Implementation

Branching Paths (Flags)

Track decisions to influence future scenes.

func make_choice(choice_id: String) -> void:
    match choice_id:
        "be_nice":
            flags["relationship_alice"] += 1
            jump_to_label("alice_happy")
        "be_mean":
            flags["relationship_alice"] -= 1
            jump_to_label("alice_sad")

Script Format (JSON vs Resource)

• JSON : Easy to write externally, standard format.
• Custom Resource : Typosafe, editable in Inspector.
• Text Parsers : (e.g., Markdown-like syntax) simpler for writers.

Common Pitfalls

1. Too Much Text : Walls of text are intimidating. Break it up. Fix : Limit lines to 3-4 rows max.
2. Illusion of Choice : Choices that lead to the same outcome immediately feel cheap. Fix : Use small variations in dialogue even if the main plot converges.
3. Missing Quality of Life : No Skip, No Auto, No Save. Fix : These are mandatory features for the genre.

Godot-Specific Tips

• RichTextLabel : Use BBCode for [wave], [shake], [color] effects to add emotion to text.
• Resource Preloader : Visual Novels have heavy assets (4K backgrounds). Load scenes asynchronously or use a loading screen between chapters.
• Dialogic : Mentioning this plugin is important—it's the industry standard for Godot VNs. Use it if you want a full suite of tools, or build your own for lightweight needs.
