2D Game Development Engine 5

Question 1

What is frame-based sprite animation?

Accepted Answer

Cycling through a sequence of sprite images over time

Answer

Frame-based animation displays a sequence of sprite frames in order to create motion.

Question 2

What does an animation state machine help manage in a 2D engine?

Accepted Answer

Transitions between animation states like idle, run, and jump

Answer

A state machine controls which animation plays and how transitions between states occur.

Question 3

What is skeletal (bone-based) 2D animation an alternative to?

Accepted Answer

Frame-by-frame sprite sheet animation

Answer

Skeletal animation rigs sprites to bones, offering smoother, more memory-efficient motion than frame sheets.

Question 4

In an engine's audio system, what does a 'mixer' or audio bus typically allow?

Accepted Answer

Grouping and adjusting volume of sound categories

Answer

Audio buses group sounds (like SFX or music) so volumes and effects can be controlled together.

Question 5

What is tweening (interpolation) used for in a 2D engine?

Accepted Answer

Smoothly animating a value between start and end over time

Answer

Tweening interpolates a property between two values over time, often with an easing curve.
