TaranisCore

A high-performance Entity Component System (ECS) engine built with TypeScript and Vite, designed for real-time applications capable of handling up to 1,000,000 entities at runtime.

🚀 Overview

TaranisCore is an ambitious ECS engine that prioritizes performance and scalability. Built with modern TypeScript and powered by Vite, it implements a sparse set architecture for optimal entity and component management. The engine is designed to push the boundaries of what's possible in browser-based real-time applications.

🎯 Key Features

• Ultra-High Performance: Designed to handle 1,000,000+ entities in real-time
• Sparse Set Architecture: Efficient memory layout and cache-friendly operations
• TypeScript First: Full type safety and excellent developer experience
• Modern Tooling: Built with Vite for lightning-fast development
• Modular Design: Clean separation of concerns with entities, components, and systems
• Test-Driven: Comprehensive test suite with Vitest

🏗️ Architecture

TaranisCore follows the Entity Component System pattern:

• Entities: Unique identifiers representing game objects
• Components: Data containers with no logic
• Systems: Logic processors that operate on entities with specific components

📖 Usage

Basic ECS Setup

import { ECS } from './src/core/ECS';
import { TransformMask } from './src/core/components/TransformMask';
import { CoreMask } from './src/core/components/CoreMask';
import { RenderSystem } from './src/core/systems';

// Create ECS instance
const ecs = new ECS(100000); // Support up to 100k entities

// Create an entity
const entityId = ecs.createEntity();

// Add components
ecs.addComponent(entityId, TransformMask.Position, { x: 100, y: 200 });
ecs.addComponent(entityId, CoreMask.Renderable, { symbol: "★", color: "gold" });

// Add systems
ecs.addSystem(new RenderSystem());

// Game loop
function gameLoop() {
    ecs.update(deltaTime);
    requestAnimationFrame(gameLoop);
}

TypeScript Bitmask System

TaranisCore features a sophisticated bitmask system built with TypeScript enums for efficient component categorization and system queries. This approach provides both type safety and performance benefits.

Component Categories

The engine organizes components into logical families using bitmasks:

// Transform-related components
export enum TransformMask {
    Position = 1 << 0, // 1 - 0x00000001
    Rotation = 1 << 1, // 2 - 0x00000010  
    Scale = 1 << 2,    // 4 - 0x00000100
}

// Core rendering components
export enum CoreMask {
    Renderable = 1 << 0,   // 1
    HtmlElement = 1 << 1   // 2
}

// Physics components
export enum PhysicMask {
    Velocity = 1 << 0,     // 1
    Mass = 1 << 1,         // 2
    Acceleration = 1 << 2, // 4
}

// AI components
export enum AIMask {
    AIState = 1 << 0,      // 1
    BehaviorTree = 1 << 1, // 2
    Pathfinding = 1 << 2,  // 4
}

Bitmask Operations

Efficient component management through bitwise operations:

// Create entity with multiple components
let entityMask = 0;
entityMask |= TransformMask.Position | TransformMask.Rotation; // Add components
console.log(entityMask.toString(2).padStart(8, '0')); // "00000011"

// Remove specific component
entityMask &= ~TransformMask.Position; // Remove Position
console.log(entityMask.toString(2).padStart(8, '0')); // "00000010"

// Check for component presence
if (entityMask & TransformMask.Position) {
    console.log("Entity has Position component");
}

// Query entities with specific component combinations
const movableEntities = ecs.query(
    TransformMask.Position | PhysicMask.Velocity
);

Benefits

• Performance: Bitwise operations are extremely fast
• Memory Efficient: Single integer represents multiple component flags
• Type Safety: TypeScript enums provide compile-time checking
• Scalable: Easy to extend with new component families
• Query Optimization: Fast system filtering based on component combinations

Example: Tic-Tac-Toe Game
