Question 1

What is the 'game loop' responsible for?

Accepted Answer

Repeatedly processing input, updating state, and rendering

Answer

The game loop continuously handles input, updates logic, and draws each frame.

Question 2

What is a 'state machine' often used for in 2D games?

Accepted Answer

Managing distinct behaviors like idle, walk, jump, and attack

Answer

A finite state machine cleanly switches a character between defined behavior states.

Question 3

What does 'culling' (e.g., frustum or viewport culling) improve?

Accepted Answer

Performance by skipping rendering of off-screen objects

Answer

Culling avoids drawing objects outside the visible area, saving rendering work.

Question 4

In an entity-component system (ECS), what is a 'component'?

Accepted Answer

A piece of data describing one aspect of an entity

Answer

In ECS, components hold data while systems operate on entities that have them.

Question 5

What is 'object pooling' used to optimize?

Accepted Answer

Reusing objects to avoid frequent allocation and garbage collection

Answer

Object pooling recycles inactive objects instead of constantly creating and destroying them.
