Setapp Interview Questions and Answers

SOLID is a set of five design principles to make software designs more understandable, flexible, and maintainable.

• S - Single Responsibility Principle: A class should have only one reason to change.

• O - Open/Closed Principle: Software entities should be open for extension but closed for modification.

• L - Liskov Substitution Principle: Objects of a superclass should be replaceable with objects of its subclasses without aff...read more

To fix jittery movement of character, adjust the physics settings, optimize animations, and use interpolation techniques.

• Adjust physics settings such as drag and gravity to smoothen movement.

• Optimize animations by reducing keyframes or using blend trees.

• Implement interpolation techniques like Lerp or SmoothDamp for smoother transitions.

Reflection is a feature in Unity that allows scripts to access information about themselves at runtime.

• Allows scripts to access information about themselves at runtime

• Useful for creating editor tools, serialization, and debugging

• Can be used to dynamically create objects, invoke methods, and access fields

Unity uses reflection for accessing and manipulating objects at runtime.

• Unity uses reflection for accessing and manipulating components and properties of GameObjects at runtime.

• Reflection is commonly used in Unity for serialization, deserialization, and data binding.

• Reflection can be used to dynamically load assemblies and classes during runtime in Unity.

Decoupling methods help separate components in a system to reduce dependencies and improve flexibility.

• Dependency Injection: Passing dependencies as parameters instead of creating them within a class.

• Event-driven architecture: Components communicate through events rather than direct method calls.

• Interfaces: Define contracts for communication between components, allowing for interchangeable implementations.
