1681-engine / pixel / PackedPixels

Class: PackedPixels

Defined in: src/pixel/spritePixels.ts:14

A frame's opaque pixels packed in typed arrays (12 bytes a pixel instead of an object each). Iterating hands out one reused SpritePixel, so read it in the loop and keep nothing of it; at(i) reads one into a given object.

Implements

• Iterable<SpritePixel>
