Question 1

How to handle collisions in Crafty?

Accepted Answer

Crafty uses the Collision component for basic hit detection. In the Pong example, the ball uses .onHit('Paddle') to reverse direction. For more complex scenarios, you may need custom logic or community modules for advanced physics.

Question 2

Crafty or Phaser for 2D games?

Accepted Answer

Crafty is lighter and more modular with its entity-component system, ideal for structured, smaller projects. Phaser offers more features out-of-the-box like built-in physics and animations, but has a steeper learning curve and heavier footprint.

Question 3

Can Crafty games run on mobile browsers?

Accepted Answer

Yes, since Crafty is pure JavaScript and works in all major browsers, games can run on mobile. However, performance may vary with touch events, and you'll need to handle responsive design and input separately.

Question 4

How to add animations in Crafty?

Accepted Answer

Animations can be implemented using components like 'Tween' or by binding to the 'UpdateFrame' event for manual control, as shown in the ball movement example. Community modules may provide additional animation tools.

Question 5

Is Crafty suitable for multiplayer games?

Accepted Answer

Crafty handles client-side game logic well, but multiplayer requires server-side integration. You'll need to implement networking separately using technologies like WebSockets, as Crafty doesn't include built-in multiplayer support.

Question 6

How to optimize Crafty games for better performance?

Accepted Answer

Use efficient components, minimize the number of entities, and leverage event throttling. For graphics, consider using Canvas or WebGL renderers if available, and profile your game to identify bottlenecks in update loops.
