Dec 2, 2015 · I've replaced it all with a "heightmap per tile" approach - 8 bytes per collision tile, each representing the height of that column. No bitmaps, just plain ol' red height columns. I've de-scoped the different terrain types from my game's design, and I'll reimplement ledges as game objects instead.
May 30, 2017 · The Megadrive allows for 2 scrolling layers, 1 sprite layer, and one non scrolling “window” layer typically used for the games HUD (life bars, score etc.). Each scrolling layer is made of 8x8 pixel tiles. Each tile can be 16 colors, using one of any of the 4 available 16 color palettes.
The "naive" way of doing that is to use the Sonic 3D approach : have a virtual map supporting a maximum of 4096 tiles but internally you use tilemap as a frame buffer (no duplicated tiles, an uniq tile id for each tile) and just stream tiles for each new column / new row of the fly.
Feb 8, 2010 · The maximum size that any tile can be is 32x32 (I can crank that number up to whatever, if someone asks). Tiles are stored in a top to bottem format. eg: if you make a 32x32 tile, and you change the tile height to 8, those tiles that go from top to bottem will now go from left to right, 1,2,3,4.

The tool features a simple user interface focused on tilemap editing as well as different paint modes: Tile Mode, Palette Mode, Priority Mode and the Tilemap Painter, which allows the user to paint directly into the tilemap.
