Interface Custom v3 - World of Warcraft

Technical Overview

A comprehensive UI replacement for WoW 3.3.5a login screens implementing advanced Lua techniques for animation, state management, and visual enhancements.

Core Technical Components

Animation System

• Frame-based Animation Engine: Implements custom OnUpdate handlers with mathematical easing functions (BezierInterpolation, BounceOut) for smooth transitions

• Sequential Frame Animation: Renders 480 sequential BLP frames at 30fps for fluid background animations

• Dynamic Element Scaling: Utilizes scale transformations with sine-wave modulation for pulsing effects

• Alpha Channel Management: Progressive opacity transitions with cubic easing curves

State Management

• Account Persistence Layer: Multi-level data structure for credentials, character order, and notes using formatted string serialization

• Character Data Caching: Translation tables between visual index and data ID with intelligent rebuilding on character list updates

• Event-Driven Architecture: Comprehensive event registration system for UI state synchronization

Visual Framework

• Custom Texture Atlas System: Coordinates mapping for faction-specific UI elements

• Dynamic Color Application: Vertex color adjustments based on faction, class, and selection state

• Multiple Rendering Layers: Optimized draw layer management for overlapping visual elements

• Frame Pooling Implementation: Efficient resource utilization through custom frame pooling for buttons and UI elements

UI Enhancement Features

• Drag & Drop System: Full implementation of MouseDown/MouseUp/OnDragStart/OnDragStop handlers with visual feedback

• Custom Tooltip Framework: Expandable information displays with right-click toggling

• Camera Control System: Mathematical matrix transformations for smooth camera movement

• Notification System: Modal dialog management with stacking and animation

File Structure

• AccountLogin.lua: Authentication system, credential management, background animation (600+ lines)

• CharacterSelect.lua: Character management, selection UI, notes system, drag-drop (7000+ lines)

• CharacterCreate.lua: Character creation process, customization UI, camera controls (3500+ lines)

Customization Options

• Animation timing constants (e.g., PULSE_SPEED, FADE_DURATION, ANIMATION_DURATION)

• Visual appearance variables (e.g., LOGO_SIZE, CHARACTER_BUTTON_HEIGHT)

• Path constants for textures (e.g., AccountLogin_Background, LOGO_TEXTURE_PATH)

• Faction and class color definitions with RGB value mapping
