TCJSgame Pro: The Ultimate JavaScript Game Engine Evolution

After months of development and community feedback, I'm thrilled to announce TCJSgame Pro - a complete rewrite and enhancement of the beloved TCJSgame engine that takes JavaScript game development to the next level.

🚀 What's New in TCJSgame Pro?

Performance Revolution

The biggest game-changer in TCJSgame Pro is the built-in performance optimization system:

// Automatic performance optimization
display.perform(); // Switches to requestAnimationFrame with smart culling

// Or use the high-performance game loop directly
function TCJSgameGameAreaToIncreasePerformance() {
    // Smart rendering with viewport culling
    // Only renders objects within the game area
    // 60+ FPS guaranteed
}

Key Performance Features:

Smart Viewport Culling: Objects outside the game area are automatically skipped
requestAnimationFrame Integration: Buttery smooth 60 FPS gameplay
Optimized Rendering Pipeline: Reduced canvas operations
Memory Efficient: Better garbage collection management

Enhanced Camera System

class Camera {
    constructor(x = 0, y = 0, worldWidth = 1000, worldHeight = 1000) {
        this.x = x;
        this.y = y;
        this.target = null;
        this.speed = 5;
        this.worldWidth = worldWidth;
        this.worldHeight = worldHeight;
    }

    follow(target, smooth = false) {
        if (smooth) {
            // Smooth camera follow with easing
            this.x += (target.x - this.x) * 0.1;
            this.y += (target.y - this.y) * 0.1;
        } else {
            // Direct camera follow
            this.x = target.x - display.canvas.width / 2;
            this.y = target.y - display.canvas.height / 2;
        }
    }
}

Advanced Movement Physics

// New acceleration and deceleration system
move.accelerate(player, 0.5, 0, 10, 10); // (object, accelX, accelY, maxSpeedX, maxSpeedY)
move.decelerate(player, 0.1, 0.1); // Smooth stopping

// Projectile motion with realistic physics
move.project(bullet, 10, 45, 0.1); // (object, velocity, angle, gravity)

// Smart positioning
move.position(player, "center"); // "top", "bottom", "left", "right", "center"

Particle System Built-in

// Create stunning particle effects with one line
const explosion = new ParticleSystem(
    x, y,           // Position
    "orange",        // Color
    50,              // Particle count
    5,               // Size
    10,              // Speed
    60,              // Lifetime (frames)
    0.1              // Gravity
);

// Particles automatically handle physics and cleanup

Enhanced Tilemap Engine

// Advanced tilemap management
display.tileMap(); // Initialize tile system

// Dynamic tile manipulation
tileMap.add(tileId, x, y);    // Add tile at position
tileMap.remove(x, y);         // Remove tile
tileMap.rTile(x, y);          // Get tile reference

// Smart collision detection
if (tileMap.crashWith(player, tileId)) {
    // Handle specific tile type collisions
}

Improved Audio System

// Robust audio handling with automatic retry
const sound = new Sound("explosion.mp3");
sound.volume = 0.7; // Easy volume control
sound.play(); // Automatic retry on browser restrictions

// Handles modern browser audio policies gracefully

📚 Getting Started

Basic Setup

<!DOCTYPE html>
<html>
<head>
    <title>My TCJSgame Pro Game</title>
</head>
<body>
    <script src="tcjsgame-pro.js"></script>
    <script>
        // Initialize display
        const display = new Display();
        display.start(800, 600);

        // Create a player
        const player = new Component(50, 50, "blue", 100, 100, "rect");
        player.physics = true;
        display.add(player);

        // Game loop
        function update() {
            // Input handling
            if (display.keys[39]) player.speedX = 5;  // Right arrow
            if (display.keys[37]) player.speedX = -5; // Left arrow
            if (display.keys[38]) player.speedY = -5; // Up arrow
            if (display.keys[40]) player.speedY = 5;  // Down arrow

            // Camera follows player smoothly
            display.camera.follow(player, true);
        }

        // Enable performance mode
        display.perform();
    </script>
</body>
</html>

Advanced Example: Platformer Game

// Create player
const player = new Component(32, 32, "red", 50, 50, "rect");
player.physics = true;
player.bounce = 0.2;
display.add(player);

// Create platforms using tilemap
display.map = [
    [1, 1, 1, 1, 1, 1, 1, 1],
    [0, 0, 0, 0, 0, 0, 0, 0],
    [0, 0, 0, 0, 0, 0, 0, 0],
    [1, 1, 0, 0, 0, 0, 1, 1],
    [0, 0, 0, 0, 0, 0, 0, 0],
    [1, 1, 1, 1, 1, 1, 1, 1]
];

display.tile = [
    null, // 0 = empty
    new Component(100, 30, "green", 0, 0) // 1 = platform
];

display.tileMap();

// Game logic
function update() {
    // Jump when space is pressed and on ground
    if (display.keys[32] && player.gravitySpeed === 0) {
        player.gravitySpeed = -15;
    }

    // Horizontal movement
    player.speedX = 0;
    if (display.keys[39]) player.speedX = 5;
    if (display.keys[37]) player.speedX = -5;

    // Camera follow
    display.camera.follow(player, true);
}

🔧 Performance Tips

Use display.perform() for automatic optimization
Enable physics only when needed on components
Use tilemaps for static level geometry
Hide off-screen objects with component.hide()
Use particle systems for multiple similar objects
