Class TileLayer

java.lang.Object

com.codename1.gaming.level.TileLayer

public class TileLayer
extends Object

An efficient, single-tileset tile grid: a #getCols() x #getRows() array of frame indices into one SpriteSheet (-1 means "empty cell").

This is the fast representation a game uses when every tile comes from the same atlas -- contrast with a Layer of Layer.Kind#TILE, which stores an assetId-per-cell map and can mix assets from different packs. #toScene(Scene, int) materializes the non-empty cells as Sprites anchored at their top-left at tileSize spacing.
