What is a sprite atlas (texture atlas) used for in a 2D engine?
Answer: Packing many images into one texture to reduce draw calls
A texture atlas combines many sprites into one texture, reducing draw calls and improving performance.
Which technique batches many sprites into a single draw call?
Answer: Sprite batching
Sprite batching groups sprites sharing a texture into one draw call for efficiency.
In a tile-based 2D engine, what is a tilemap?
Answer: A grid of indexed tiles forming a level
A tilemap is a grid referencing tiles from a tileset to build levels efficiently.
What is the benefit of object pooling in a 2D engine?
Answer: Reusing objects to reduce allocation and garbage collection
Object pooling reuses pre-allocated objects, reducing runtime allocations and GC spikes.
What does a camera component typically control in a 2D engine?
Answer: The viewport's position, zoom, and what is visible
The camera defines the visible viewport, including position and zoom over the game world.
Which coordinate concept lets a sprite move correctly relative to its parent in a scene graph?
Answer: Local vs world transforms
Local transforms are combined with parent transforms to produce world-space positions.
What is culling in the context of 2D rendering?
Answer: Skipping off-screen objects to save rendering work
Culling avoids rendering objects outside the camera view to improve performance.
