16x6 Map Editor

16x6 Map Editor (c) CLOCKWIZE 1989


==================================





This program was written for in-house use only and allowed us to generate game


maps for titles such as Punch and Judy, and Gilbert (see these titles for example


tiles and maps to load in)





Each screen or 'room' of the game was made by piecing together pre-drawn


2x2 character sized blocks or 'tiles'. Although the editor can create rooms that


are 16 tiles wide, each room of Punch and Judy, and Gilbert were only 14 tiles


wide so the unused data was deleted from the source code








Editor Menu Options


====================





1. SCREEN$s of tiles are loaded using this. The screen is loaded higher up


in RAM. The tiles must be 2x2 characters in size (16x16 pixels) and must


be laid out 'snapped' to character (attribute) positions, starting top left,


with one free character in between horizontally and vertically. A full


screen can therefore contain 88 tiles (8 rows of 11 tiles)





2. Grab screen. This 'grabs' the tiles from the screen loaded using the above


menu item. The program asks you the starting index of the tiles you


are to grab, the first tile is at index 0. All tiles are grabbed from left


to right starting at the top of the screen. The bitmaps are stored separately


from attribute data





3. View screen simply shows you the SCREEN$ loaded using menu item 1





4. Load tiles. Pre-grabbed tiles can be re-loaded from tape with this option





5. Load Maps. Maps can be re-loaded from tape





6. Save Maps. Working maps can be saved to tape





7. Save tiles. Grabbed tiles can be saved to tape





8. Enter designer...
