Quiz Questions Overview
1. What standard game AI algorithm is used to calculate unbeatable moves in 2-player grid games like Tic-Tac-Toe?
Minimax Algorithm
A* Pathfinding
Dijkstra Search
Monte Carlo Tree
Answer note: Minimax evaluates all possible future game moves to maximize player advantage while minimizing opponent score potential.
2. In 2D physics engines, what formula governs constant acceleration under simulated gravity?
v = v0 + g * t
E = mc^2
F = m / a
p = m * v
Answer note: Vertical velocity increases by gravity (g) over time step intervals, creating smooth jump arcs!
3. What is the term for an invisible geometric boundary used by game engines to detect collisions between objects?
Viewport
Hitbox
Render Matrix
Sprite Mesh
Answer note: Hitboxes are bounding boxes or circles used for rapid mathematical collision detection.
4. When a projectile bounces off a flat wall, how is its reflection vector angle calculated?
Angle of Incidence = Angle of Reflection
Reflect at 90 degrees always
Double the incoming speed
Randomized rebound
Answer note: According to reflection physics, the angle of incidence equals the angle of reflection relative to the wall normal.
5. What rendering technique allows 2D games to simulate 3D depth by moving background layers slower than foreground layers?
Raycasting
Parallax Scrolling
Texture Mapping
Anti-Aliasing
Answer note: Parallax scrolling moves multi-layered background sprites at varying speeds to create a sensation of 3D depth.
