# LoreCraft Development Log

**Last Updated**: August 19, 2025  

**Version**: 0.6.0 (Corruption System Update)  

**Platform**: Web (Mobile-First)  

---

## 🎯 Project Overview

LoreCraft is a mobile-first turn-based element fusion puzzle game with AI-generated dynamic theming. Players fuse elements on a 7x7 grid while battling villains in a tug-of-war progression system, featuring a sophisticated corruption mechanic and dynamic storytelling powered by the GAGE (Generative Adversarial Game Engine) system.

---

## 🏗️ Major System Implementations

### 1. **GAGE System Integration** (AI-Powered Dynamic Content)

#### **Core GAGE Architecture**

- **Dynamic Theme Generation**: AI-generated villains, prisoners, and backgrounds

- **Adaptive Storytelling**: Context-aware narrative generation based on game state

- **Character Portrait System**: Real-time character image generation and loading

- **Theme Audio Mapping**: Dynamic audio sets that match visual themes

#### **GAGE Implementation Details**

```javascript

// AssetLoader.js - GAGE Integration

class AssetLoader {

    async loadGAGETheme(themeName) {

        const response = await fetch(`https://api.gage.example.com/themes/${themeName}`);

        const themeData = await response.json();

       
        return {

            villain: {

                name: themeData.villain.name,

                description: themeData.villain.description,

                imageUrl: themeData.villain.portrait

            },

            prisoner: {

                name: themeData.prisoner.name,

                description: themeData.prisoner.description,

                imageUrl: themeData.prisoner.portrait

            },

            backgroundUrl: themeData.environment.background,

            colorScheme: themeData.colorScheme

        };

    }

}

```

#### **Character Portrait Loading System**

- **Asynchronous Loading**: Images loaded in background while game initializes

- **Fallback System**: Graceful degradation to placeholder images

- **CSS Specificity Handling**: Used `!important` declarations to override conflicting styles

- **Real-time Updates**: Character portraits update dynamically when themes change

#### **LORE Page Integration**

- **Dynamic Character Flanking**: NPC portraits positioned left and right of "LORE" title

- **Theme-Aware Styling**: Background colors and borders adapt to current theme

- **Loading Synchronization**: LORE page waits for character images before displaying

### 2. **Corruption System** (v6.0) - Advanced Game Mechanic

#### **4-Turn Lifecycle Implementation**

```javascript

// CorruptionSystem.js

class CorruptionSystem {

    processCorruptionDecay() {

        this.corruptionCells.forEach(corruption => {

            corruption.turnsRemaining--;

           
            if (corruption.turnsRemaining === 1) {

                // Phase 1 → Phase 2 transition

                this.transitionToPhase2(corruption);

            } else if (corruption.turnsRemaining <= 0) {

                // Corruption becomes debris

                this.convertToDebris(corruption);

            }

        });

    }

}

```

#### **Adjacent Tile Effects**

- **Phase 1 (Turns 0-2)**: Adjacent tiles get red borders, become locked and unmergeable

- **Phase 2 (Turns 3-4)**: Adjacent tiles get yellow borders, become unmovable but mergeable

- **Visual Feedback**: Real-time CSS class application for immediate player feedback

- **Audio Integration**: Corruption spawn/decay sounds with MP3 format

#### **Technical Challenges Solved**

- **Competing Decay Systems**: Removed duplicate corruption logic from TileSpawner

- **Asset References**: Changed `rubble` → `debris` to match existing assets

- **UI Conflicts**: Disabled mobile-enhancements.js updateUI wrappers

- **CSS Targeting**: Added `.cell` selectors for corruption border effects

### 3. **Mobile-First Architecture**

#### **Touch System Implementation**

```javascript

// SlidingTileSystem.js

class SlidingTileSystem {

    handleTouchStart(event) {

        event.preventDefault();

        const touch = event.touches[0];

        this.inputType = 'touch';

        this.startDrag(touch.clientX, touch.clientY);

    }

   
    // Mouse snapping functionality

    getCellUnderCursor(x, y) {

        const elements = document.elementsFromPoint(x, y);

        for (const element of elements) {

            const cell = element.closest('.cell');

            if (cell && cell.dataset.index) return cell;

        }

        return null;

    }

}

```

#### **Mobile Enhancements**

- **Haptic Feedback**: Light/medium/heavy vibrations for different game actions

- **Gesture Support**: Double-tap, long-press, swipe interactions

- **One-Thumb Operation**: All controls within comfortable thumb reach

- **Performance Optimization**: 60fps animations with hardware acceleration

#### **Cross-Platform Compatibility**

- **iOS Safari Fixes**: Menu slider visibility and touch event handling

- **Android Optimization**: Multiple event types for broad device support

- **Webkit Transforms**: Hardware acceleration for smooth animations

### 4. **Advanced Audio System**

#### **Reliability Improvements** (Latest Update)

```javascript

// AudioManager.js - Enhanced with retry mechanism

async playAudio(eventName, volume = 1.0, retryCount = 0) {

    const maxRetries = 2;

   
    try {

        // Safe audio cloning with fallback

        let audioClone;

        try {

            audioClone = audio.cloneNode();

            if (!audioClone) throw new Error('Clone failed');

        } catch (cloneError) {

            console.warn(`Audio clone failed for ${eventName}, using original`);

            audioClone = audio;

        }

       
        // Enhanced play with proper promise handling

        const playPromise = audioClone.play();

        if (playPromise !== undefined) {

            await playPromise;

            return true;

        }

    } catch (error) {

        if (retryCount < maxRetries) {

            await new Promise(resolve => setTimeout(resolve, 100 + retryCount * 100));

            return this.playAudio(eventName, volume, retryCount + 1);

        }

    }

}

```

#### **Autoplay Restriction Handling**

- **User Interaction Detection**: Automatically unlocks audio after first user interaction

- **Audio Queueing**: Pending audio calls processed after interaction

- **Enhanced Preloading**: Audio "warming" with silent 0-volume playback

#### **Debug Tools**

```javascript

// Global audio testing functions

window.testAudioReliability()    // Test 10 sequential audio calls

window.forceAudioEnable()        // Bypass interaction requirement

window.audioManager.testAudioPlayback()  // Individual audio test

```

### 5. **Responsive Design System**

#### **Dynamic Viewport Management**

```javascript

// Dynamic viewport height fix for iOS Safari

function setDocHeight() {

    const vh = window.innerHeight * 0.01;

    document.documentElement.style.setProperty('--dvh', `${vh}px`);

}

```

#### **Container Width Issues Resolution**

- **Problem**: Game grid exceeded header width on fullscreen PC browsers around 768px

- **Solution**: Applied `max-width: 600px` constraint to viewport container only

- **Implementation**: CSS media queries for responsive breakpoints

#### **Loading Page Logo Enhancement**

- **Updated Asset**: Changed from `logo.png` to `logo-color.webp`

- **Square Container**: Perfect square containers at all screen sizes

- **Image Filling**: Removed padding and scaled logo to 140% to crop white borders

---

## 🎮 Core Game Systems

### **Turn-Based Combat**

- **Player Turn**: Drag tiles to slide/fuse, each action triggers villain response

- **Villain Turn**: Spawns new tiles, may spawn corruption based on frustration level

- **Tug-of-War Progression**: Hope vs Frustration meter with visual feedback

### **Element Fusion System**

- **31 Core Recipes**: Carefully balanced fusion combinations

- **11 Recycle Recipes**: Advanced late-game combinations

- **Recipe Discovery**: Audio-visual feedback for new discoveries

- **Tier Progression**: Elements advance through multiple tiers

### **Chain System**

```javascript

// ChainSystem.js - Advanced pattern detection

detectPatternChain(startCell, endCell) {

    // AABB pattern detection

    // Board-wide same element chains (7+ instances)

    // Horizontal/vertical line patterns

    // Two-two fusion combinations

}

```

### **Victory Conditions**

- **Fragment Collection**: Gather 3 fragments (Courage/Ingenuity/Defiance)
