Genre: Party / Minigame Collection

Expert blueprint for party games balancing accessibility, variety, and social fun.

NEVER Do (Expert Anti-Patterns)

Multiplayer & Input

• NEVER hardcode player inputs to specific joypad IDs (e.g., 0 or 1); strictly query dynamically via Input.get_connected_joypads().
• NEVER bake player-IDs into the input map (e.g., "p1_jump"); strictly use a Dynamic Input Router to map physical controllers to players at runtime.
• NEVER use Input.is_action_pressed() for assigning new player joins; strictly parse raw InputEventJoypadButton in _unhandled_input() for device metadata.
• NEVER allow inconsistent controls between games; strictly standardize across all minigames (A = Accept/Action , B = Back/Cancel , Joystick = Move).
• NEVER assume a disconnected joypad removes a player; strictly connect to the joy_connection_changed signal to pause and handle dropouts gracefully.
• NEVER use boolean polling for analog sticks; strictly use Input.get_vector() for precision and deadzones.

User Experience & Feedback

• NEVER use long text-based tutorials; strictly use a 3-second looping GIF + a single-sentence instruction overlay (e.g., "Mash A to fly!").
• NEVER ignore "Asymmetric" balance in 1v3 games; strictly provide the "One" with unique abilities or increased HP/speed to offset the numerical disadvantage.
• NEVER neglect Accessibility and Handicap systems; strictly implement optional support (e.g., speed boosts for lower-skilled players) to keep the competition social.
• NEVER leave UI Control nodes with FOCUS_NONE for gamepad menus; strictly set to FOCUS_ALL with explicit focus neighbors for accessible navigation.

Rendering & Architecture

• NEVER use heavy scene transitions; strictly keep minigame assets light and use Threaded Background Loading while the instructions screen is active.
• NEVER draw global CanvasLayer UI for individual split-screen players; strictly use per-viewport CanvasLayer children.
• NEVER manually set sizes on SubViewport children; strictly use GridContainer or BoxContainer for automatic split-screen layout.
• NEVER store tournament state or scores inside minigame scenes; strictly use a Persistent Autoload (Singleton).
• NEVER use a static Camera2D for shared-room games; strictly use a dynamic group camera that zooms/pans to fit all players in frame.
• NEVER overlap SubViewportContainer nodes without setting mouse_filter to ; otherwise, top viewports will block input.

🛠 Expert Components (scripts/)

Original Expert Patterns

• party_input_router.gd - Professional local multiplayer solution mapping device_id to player_id.

Modular Components

• player_join_manager.gd - Slot mapping logic using raw JoypadButton event parsing.
• split_screen_manager.gd - SubViewport synchronization for shared physics worlds.
• tournament_state.gd - Persistent Autoload singleton for cross-scene state.

Core Loop

1. Lobby : Players join and select characters/colors.
2. Meta : Players move on a board or vote for the next game.
3. Play : Short, intense minigame (30s - 2m).
4. Score : Winners get points/coins.
5. Repeat : Cycle continues until a turn limit or score limit.

Skill Chain

Architecture Overview

1. Minigame Definition

Using Resources to define what a minigame is.

# minigame_data.gd
class_name MinigameData extends Resource

@export var title: String
@export var scene_path: String
@export var instructions: String
@export var is_1v3: bool = false
@export var thumbnail: Texture2D

2. The Party Manager

Singleton that persists between minigames.

# party_manager.gd
extends Node

var players: Array[PlayerData] = [] # Tracks score, input_device_id, color
var current_round: int = 1
var max_rounds: int = 10

func start_minigame(minigame: MinigameData) -> void:
    # 1. Show instructions scene
    await show_instructions(minigame)
    # 2. Transition to actual game
    get_tree().change_scene_to_file(minigame.scene_path)
    # 3. Pass player data to the new scene
    # (The minigame scene must look up PartyManager in _ready)

3. Minigame Base Class

Every minigame inherits from this to ensure compatibility.

# minigame_base.gd
class_name Minigame extends Node

signal game_ended(results: Dictionary)

func _ready() -> void:
    setup_players(PartyManager.players)
    start_countdown()

func end_game() -> void:
    # Calculate winner
    game_ended.emit(results)
    PartyManager.handle_minigame_end(results)

Key Mechanics Implementation

Local Multiplayer Input

Handling dynamic device assignment.

# player_controller.gd
@export var player_id: int = 0 # 0, 1, 2, 3

func _physics_process(delta: float) -> void:
    var device = PartyManager.players[player_id].device_id
    # Use the specific device ID for input
    var direction = Input.get_vector("p%s_left" % player_id, ...) 
    # Better approach: Remap InputMap actions at runtime explicitly

Asymmetric Gameplay (1v3)

Balancing the "One" vs the "Many".

• The One : Powerful, high HP, unique abilities (e.g., Bowser suit).
• The Many : Weak individually, must cooperate to survive/win.

Godot-Specific Tips

• SubViewport : Powerful for 4-player split-screen. Each player gets a camera, all rendering the same world (or different worlds!).
• InputEventJoypadButton : Use Input.get_connected_joypads() to auto-detect controllers on the Lobby screen.
• Remapping : Godot's InputMap system can be modified at runtime using InputMap.action_add_event(). Creating "p1_jump", "p2_jump" dynamically is a common pattern.

Common Pitfalls

1. Long Tutorials : Players just want to play. Fix : 3-second looping GIF + 1 sentence instruction overlay before the game starts.
2. Downtime : Loading times between 10-second minigames. Fix : Keep minigame assets light. Use a "Board" scene that stays loaded in the background if possible, or use creating Thread loading.
3. Confusing Controls : Minigame A uses "A" to jump, Minigame B uses "B". Fix : Standardize. "A" is always Accept/Action. "B" is always Back/Cancel.
