Senior Game Developer Interview Questions and Answers

Unity handles memory through garbage collection. Subscription and unsubscription of event delegate base methods are used to manage event listeners efficiently.

• Unity uses garbage collection to manage memory, automatically deallocating memory when objects are no longer needed.

• Subscribing to events adds a listener to an event delegate, while unsubscribing removes the listener to prevent memory leaks.

• Using subscription and unsubscription helps in efficient management of event lis...read more

Optimize rendering by reducing draw calls, using efficient assets, and implementing techniques like sprite sheets and requestAnimationFrame.

• Minimize draw calls by combining multiple sprites into a single texture atlas.

• Use requestAnimationFrame for smoother animations instead of setInterval.

• Reduce asset sizes by compressing images and using lower resolution textures.

• Implement object pooling to reuse game objects instead of constantly creating and destroying them.

• Limit the numb...read more

I prioritize efficient algorithms, asynchronous processing, and event-driven design to maintain game responsiveness.

• Use object pooling to minimize memory allocation and garbage collection, improving performance during gameplay.

• Implement asynchronous loading for assets, allowing the game to remain responsive while resources are being fetched.

• Utilize a fixed timestep for physics calculations to ensure consistent behavior regardless of frame rate fluctuations.

• Adopt an event-driv...read more

Static methods belong to the class itself, while normal methods belong to instances of the class.

• Static methods are called on the class itself, not on instances

• Normal methods are called on instances of the class

• Static methods cannot access instance variables, while normal methods can

A polyfill is code that implements a feature on web browsers that do not support it natively.

• Polyfills allow developers to use modern JavaScript features in older browsers.

• Example: A polyfill for Array.prototype.includes can be implemented as follows: if (!Array.prototype.includes) { Array.prototype.includes = function(value) { return this.indexOf(value) !== -1; }; }

• They are often used for methods like Promise, Fetch API, and Object.assign.

• Polyfills can be included via script...read more
