Whats the difference between block layers and map layers ?
A ‘block layer’ in Mappy is a graphic that is part of a block structure, you can see the in the block properties dialogue above BG, FG1, FG2 and FG3. These are drawn by calls to MapDrawBG etc. This allows you to layer sprites in between the block layers. A ‘map layer’ is a complete map array, or basically what is shown in the main window in Mappy. These can be edited in the ‘layers’ menu of MappyWin32. It is often not necessary to have more than one layer, although you’ll see a good use for a second one in Mappy tutorial 1 (on the Mappy site).
