The map editor supports arbitrary sized maps of individually sized tiles. A tile is a rectangular layout of characters and colors.
Map Pane
Here the actual map editing is done. Choose tiles and paint with left mouse button. Right mouse button fetches the tile under the mouse pointer.
On this screen tiles are created and modified. Tiles can have differing sizes. However the map editor only allows putting tiles at fixed step sizes.
On the project pane several import/export functions are available.
Export data as assembly
The chosen data will be exported as assembly.
"Tiles as elements" will export tiles with width and height arrays plus tile character and color data as consecutive arrays.
"Tiles as data" will export tiles with sparse arrays for every character/color cell.
"Map data" will export map data as consecutive arrays in the orientation chosen.
"Tile data, then map data" appends "Tiles as data" and "Map data".
