SpriteSheet

The frames of one texture.

interface SpriteSheet

import type { SpriteSheet } from '@driftengine/ui2d';

In depth

Two flat arrays and a name index rather than an array of objects: reading a frame in a draw loop is four Float32Array reads and no property lookups, and a tilemap does that per tile.
