LINX - Example Game Built with CASCADA

Territory network game demonstrating CASCADA Framework features

Overview

LINX is a complete game example built with CASCADA Framework to demonstrate:

Graph-based gameplay (Nodes & Edges)
Vue UI integration (MainMenu + GameHUD)
Visual themes system
Energy economy
Bot AI
Infinite mode with persistent scores

Source code: src/game/territory/

Play: pnpm dev → http://localhost:5173

Game Rules

Objective

Create closed polygons between nodes to capture enemy territory. The player with the most controlled area after 60 seconds wins the round.

Mechanics

Click → Create your node (your color)
Drag between your nodes → Form connections
Closed polygon (3-6 nodes) → Capture territory
Enemies inside polygon → Captured and destroyed
Double-click node → Delete it (breaks all territories)
Energy management → Spend wisely or get eliminated

Energy Economy

Starting energy: 100
Create node: -10 energy
Capture enemy: +30 energy
Destroy enemy edge: +5 energy
Out of energy → Eliminated!

First Polygon Rule

Your first polygon must:

Be exactly 3 nodes (triangle)
Capture an enemy inside

If it fails → instant elimination!

Infinite Mode

Rounds last 60 seconds
Score carries over between rounds
Energy persists
Lost a round? → Eliminated
Keep playing until final elimination

Architecture

How LINX Uses CASCADA Framework

Platform Layer:

src/platform/base-config.ts → Used by game config

Core Layer:

src/core/ui/ui-manager.ts → UI management
src/core/ui/vue-ui-bridge.ts → Vue integration
src/core/config/visual-themes.ts → Theme system

Game Layer (LINX):

src/game/config/game-config.ts → Extends base config
src/game/territory/scenes/territory-game-scene.ts → Main game logic
src/game/scenes/main-menu-scene-vue.ts → Menu with Vue
src/game/ui/main-menu-ui.vue → Menu Vue component
src/game/ui/game-hud.vue → HUD Vue component

Layer hierarchy respected:

Game → uses Core + Platform
Core → uses Platform
Platform → independent

Visual Themes

LINX demonstrates the theme system with 4 styles:

1. Minimal (Default)

Black & white
Monospace font
Clean and simple

2. Neon Grid

Cyberpunk aesthetic
Cyan/Magenta/Yellow
Glow effects
Scanlines

3. Brutalist

Industrial style
Gray tones
Thick strokes
Noise effects

4. Liquid Crystal

Holographic
Color shifting (HSL rotation)
Smooth animations

Implementation: src/core/config/visual-themes.ts

Vue UI Integration

Main Menu (`main-menu-ui.vue`)

Features:

Horizontal swipeable theme selector
Reactive theme switching
Smooth animations
Responsive layout

Code:

vue

<template>
  <div class="main-menu">
    <h1>LINX</h1>
    <button @click="$emit('start-game')">START</button>
    <!-- Theme selector -->
  </div>
</template>

Game HUD (`game-hud.vue`)

Features:

Timer (top center)
Score and area (top right)
Energy bar (bottom center)
Hints (center, auto-hide)

Code:

vue

<template>
  <div class="game-hud">
    <div class="timer">{{ formattedTime }}</div>
    <div class="energy-bar" :style="{ width: energyPercent + '%' }"></div>
  </div>
</template>

Reactivity:

typescript

// In TerritoryGameScene.ts
this.vueBridge.updateProps("game-hud", {
  time: this.gameTime,
  energy: myPlayer.energy,
  score: myPlayer.score,
});

100% reactive! Props update → Vue re-renders instantly.

🤖 Bot AI

LINX includes simple bot AI to demonstrate game systems:

Bot behavior:

Create nodes randomly in valid positions
Form polygons when 3+ nodes are available
Target areas with enemies inside
Manage energy (stop creating if low)

Implementation: src/game/territory/scenes/territory-game-scene.ts → botAction()

Game State Management

Entities

Nodes:

typescript

interface Node {
  id: string;
  x: number;
  y: number;
  playerId: string;
  energyValue: number;
  visual?: Phaser.GameObjects.Arc;
  glow?: Phaser.GameObjects.Arc;
}

Edges:

typescript

interface Edge {
  id: string;
  fromNodeId: string;
  toNodeId: string;
  playerId: string;
  energyValue: number;
  energyFlow: number; // 0-1 for animation
  visual?: Phaser.GameObjects.Graphics;
}

Territories:

typescript

interface Territory {
  id: string;
  playerId: string;
  polygonNodes: string[]; // Node IDs
  area: number; // Calculated via Shoelace formula
  visual?: Phaser.GameObjects.Graphics;
}

Cleanup

Manual (old way):

typescript

for (const node of this.nodes.values()) {
  node.visual?.destroy();
  node.glow?.destroy();
}
this.nodes.clear();
// Repeat for edges, territories...

With EntityRegistry (future):

typescript

this.entityRegistry.clearRegion("game-area"); // 1 line!

Technical Highlights

1. Polygon Area Calculation

Using Shoelace formula for arbitrary polygons:

typescript

private calculatePolygonArea(nodes: Node[]): number {
  let area = 0;
  const n = nodes.length;
  for (let i = 0; i < n; i++) {
    const j = (i + 1) % n;
    area += nodes[i].x * nodes[j].y;
    area -= nodes[j].x * nodes[i].y;
  }
  return Math.abs(area) / 2;
}

2. Color Contrast Check

Ensuring distinct player colors:

typescript

private getColorDistance(c1: number, c2: number): number {
  const r1 = (c1 >> 16) & 0xff;
  const g1 = (c1 >> 8) & 0xff;
  const b1 = c1 & 0xff;
  // ... same for c2
  return Math.sqrt((r2 - r1) ** 2 + (g2 - g1) ** 2 + (b2 - b1) ** 2);
}

Minimum distance: 100 (RGB space).

3. Camera Parallax

Subtle movement based on pointer:

typescript

update() {
  this.cameraOffsetX += (this.pointerX * 0.01 - this.cameraOffsetX) * 0.1;
  this.cameraOffsetY += (this.pointerY * 0.01 - this.cameraOffsetY) * 0.1;
  this.cameras.main.setScroll(this.cameraOffsetX, this.cameraOffsetY);
}

4. Energy Flow Animation

Animated edges:

typescript

update(delta: number) {
  for (const edge of this.edges.values()) {
    edge.energyFlow += delta * 0.001;
    if (edge.energyFlow > 1) edge.energyFlow = 0;
    // Redraw edge with energyFlow position
  }
}

📈 Lessons Learned

What Worked Well

Vue UI integration - 58% less code than Phaser UI
Theme system - Easy to add new styles
Graph theory terminology - Professional, clear
Strict layer hierarchy - Clean separation

Challenges

UI duplication bug - Fixed with proper cleanup in initVueUI()
Territory validation - Complex geometry checks
Bot AI - Simple but effective

Future Improvements

🔮 EntityRegistry - Automatic cleanup
🔮 IoS integration - Multi-level gameplay
🔮 Multiplayer - Colyseus integration
🔮 Mobile controls - Touch optimizations

Key Takeaways for Your Game

If you're building a game with CASCADA, LINX demonstrates:

Start with Core - Use UIManager, themes, etc.
Extend Platform - Game config extends base config
Vue for UI - Faster development, better UX
Clean architecture - Respect layer hierarchy
Iterate quickly - HMR for instant feedback

🔮 Multi-Scale Concepts for LINX

Want to see how LINX could scale across all 5 abstraction levels?

📖 LINX Multi-Scale Gameplay Concepts

Three complete variants of scaling LINX from NANO to MEGA:

Concept 1: Fractal Aggregation (territories → super-nodes)
Concept 2: Energy States (rise and fall between levels)
Concept 3: Temporal Zoom (time speed + automation)

Each with detailed mechanics, implementation guides, and sales/marketing advantages.

🎯 Implementation Plan

📖 LINX Game Modes Menu

Structured menu with 4 playable modes:

Classic Mode - Current implementation (NANO only, infinite)
Fractal Mode - Concept 1 as playable game
Ascension Mode - Concept 2 as playable game
Temporal Mode - Concept 3 as playable game

All modes share visual themes (Minimal, Neon Grid, Brutalist, Liquid Crystal).
