🎨 Announcing Limn Engine — Draw Your Game Into Existence

The 2D Game Engine That Puts Creativity First

After years of development, countless late nights, and more cups of coffee than I can count, I'm thrilled to announce Limn Engine — a zero‑configuration, browser‑based 2D game engine designed for people who want to make games, not fight with tools.

What is Limn Engine?

Limn (verb) — to draw, paint, or portray.

It's the perfect name for an engine that helps you bring your game ideas to life, one line of code at a time.

Limn is a zero‑configuration, browser‑based 2D game engine that prioritizes creativity over complexity.

• 
  No build steps — just HTML and JavaScript


• 
  No package managers — one file, that's it


• 
  No complex tooling — start coding in seconds
  

<script src="limn.js"></script>

<script>

const display = new Display();

display.start(800, 600);



const player = new Component(40, 40, "blue", 400, 300);

display.add(player);



function update(dt) {

    if (display.keys[39]) player.speedX = 300 * dt;

    if (display.keys[37]) player.speedX = -300 * dt;

    move.bound(player);

}

</script>

That's it. Your first game, ready in seconds.

Why Another Game Engine?

Most game engines fall into two categories:

Limn bridges the gap. It's powerful enough for real games, yet simple enough for beginners. Every feature exists because I was tired of writing the same code over and over:

• 
  move.bound(player) — no more edge detection boilerplate


• 
  fixed() — UI follows the camera automatically


• 
  destroy() — memory management without headaches

"Common outcomes should be functions." That's the philosophy.

What's Inside

⚡ Dual-Renderer Performance

Limn uses a hidden "fake canvas" to cache static content (tilemaps, backgrounds). The result? 60 FPS on a Toshiba with 4GB RAM. Static elements render once, dynamic elements render on top. Simple. Fast. Effective.

📷 Professional Camera System

display.camera.follow(player, true);   // smooth follow

display.camera.shake(8, 8);            // screen shake

display.camera.setZoom(1.5);           // zoom in

display.camera.shakeRotation(0.07);    // rotational shake

🎯 Circle Collision

Perfect for coins, balls, and round enemies:

coin.enableCircleCollision(15);

if (player.crashWithCircle(coin)) collect();

🖼️ Dynamic Images

Swap images at runtime — perfect for power-ups or damage states:

player.setImage("hero_powered.png");

player.setColor("red"); // back to rectangle

🎨 Particle System with Presets

move.particles.explosion(ps, x, y, 30);

move.particles.sparkle(ps, x, y);

move.particles.blood(ps, x, y, 15);

move.particles.magic(ps, x, y);

🔊 Complete Audio System

const soundManager = new SoundManager();

soundManager.load("coin", "coin.wav");

soundManager.play("coin");

soundManager.playMusic("theme.mp3");

🗺️ Tilemap System

Levels as native JavaScript arrays — no external editors required:

const level = [

    [1,1,1,1,1],

    [1,0,2,0,1],

    [1,0,0,0,1],

    [1,1,1,1,1]

];

const tilemap = new TileMap(display, level, tiles, 800, 600);

tilemap.show();

🎭 Sprite Animation

One image, many frames. The engine handles the rest:

const hero = new AnimatedSprite("hero.png", 64, 64, 400, 300);

hero.addAnimation("idle", 0, 0, 1);

hero.addAnimation("walk", 1, 4, 8);

hero.playAnimation("walk");

📝 Rich Text with Tctxt

const score = new Tctxt("24px", "Arial", "white", 20, 40,

    "left", false, "alphabetic", "rgba(0,0,0,0.5)", 10, 5);

score.setText("Score: 0");

The Numbers

The Story

Limn Engine started on a Toshiba laptop with 4GB RAM, offline W3Schools, and borrowed siblings' laptops. No team. No funding. Just determination.
