Secrets & Easter Eggs (Mechanics)

Overview

This skill provides reusable components for hiding content behind specific player actions (e.g., Konami code, repetitive interaction) and managing the persistence of these discoveries.

Core Components

secret_meta_persistence.gd

Expert logic for saving global unlocks and discovery flags across all save profiles.

secret_visibility_detector.gd

View-dependent hidden wall detection using optimized Dot Product calculations.

secret_sequence_combo_matcher.gd

Professional time-sensitive input buffer for detecting complex cheat combos and sequences.

secret_interaction_spam_tracker.gd

Logic for tracking repetitive player actions to trigger curiosity-based Easter Eggs.

secret_audio_environment_occluder.gd

Spatial logic for dynamically adjusting AudioBus effects in sealed or hidden areas.

secret_progress_threshold_unlocker.gd

Percentage-based unlocker for meta-content and 'True Ending' triggers.

secret_random_encounter_spawner.gd

Weighted random system for rarest-tier entities and secret vendor encounters.

secret_lockout_cheat_guard.gd

Anti-brute-force lockout manager to protect secret integrity.

secret_vfx_discovery_glimmer.gd

Subtle procedural visual cues for hinting at hidden interactables.

secret_konami_legacy_code.gd

Specialized implementation of the iconic Konami code using the buffer matcher.

Usage Example (Cheat Code)

# In your Game Manager or Player Controller
@onready var cheat_watcher = $InputSequenceWatcher

func _ready():
    # Define UP, UP, DOWN, DOWN...
    cheat_watcher.sequence = [
        "ui_up", "ui_up", "ui_down", "ui_down"
    ]
    cheat_watcher.sequence_matched.connect(_on_cheat_unlocked)

func _on_cheat_unlocked():
    print("God Mode Enabled!")
    SecretPersistence.unlock_secret("god_mode")

NEVER Do (Expert Secret Rules)

Discovery & Triggers

• NEVER hardcode input checks in _process — Frame-dependent polling is unreliable for fast combos. Always use an event-based buffer like secret_sequence_combo_matcher.gd.
• NEVER use complex Raycasts for 'LookingAt' secrets — Physics raycasts are expensive if every wall is checking. Use the Dot Product method in secret_visibility_detector.gd for overhead efficiency.
• NEVER make 'Hidden Walls' identical to real walls — Players need a subtle "Glimmer" or texture discrepancy. Total invisibility isn't a secret; it's a bug to the player.

Persistence & Meta

• NEVER save "Secrets Found" in the main Save Slot — If the player deletes their save to try a different build, their meta-progress (Gallery, Achievement flags) should persist. Use secret_meta_persistence.gd.
• NEVER trust client-side cheat validation in Peer-to-Peer — If a secret grants a stat boost, other peers should validate the "Unlock" to prevent simple memory-editing cheats.
• NEVER use PlayerPrefs (Godot's equivalent of Settings) for secrets — Use a dedicated user://secrets.cfg.

UX & Anti-Brute Force

• NEVER allow unlimited rapid-fire cheat attempts — A simple macro can brute-force a 4-button combo in seconds. Use secret_lockout_cheat_guard.gd to add a penalty for excessive failures.
• NEVER trigger a secret without an 'Aha!' audio/visual cue — The reward for finding a secret is the *feeling* of discovery. Use secret_audio_environment_occluder.gd to change the atmosphere.
