Question 1

What is the purpose of a 'finite state machine' (FSM) in 2D game AI?

Accepted Answer

Modeling entity behavior as a set of states with defined transitions between them

Answer

An FSM organizes AI behavior into discrete states (patrol, chase, attack) and defines the conditions that cause the AI to switch between them.

Question 2

What is 'lerp' (linear interpolation) commonly used for in 2D games?

Accepted Answer

Smoothly transitioning a value between a start and end point over time

Answer

Lerp calculates intermediate values between two points based on a 0–1 parameter, used for smooth camera follow, UI transitions, and object movement.

Question 3

What is 'input buffering' in 2D action games?

Accepted Answer

Recording a player input slightly before the action is valid so it executes at the earliest opportunity

Answer

Input buffering stores a recent input command for a brief window so it triggers as soon as the relevant condition is met, making controls feel responsive.

Question 4

What is 'scene management' in a 2D game engine?

Accepted Answer

Loading, unloading, and transitioning between different game screens and levels

Answer

Scene management handles loading level data, transitioning to new scenes (menus, levels, cutscenes), and cleaning up previous scene resources.

Question 5

What is 'data serialization' used for in 2D game development?

Accepted Answer

Converting game state to a storable format (JSON, binary) for saving and loading

Answer

Serialization transforms runtime objects (player stats, level state) into a storable byte format that can be written to disk and deserialized to restore the game state.
