colours uses 512 bytes, it only needs the tile miser to eliminate 2 duplicate tiles to save you 1k of memory ! Also, if you have duplicate tiles and accidentally use both of them on the map, you can have problems detecting which tile your player is standing on, as although the tiles look the same, they will have different tile numbers !

Once you have decided on these settings for your tiles, click on the GO ! button. This will activate the Tile grabber and grab all the tiles from the loaded screen. If the Tile Tidy option has been activated, it will automatically scan and eliminate duplicated tiles after the grab.

If there are more than 256 tile in memory after grabbing and Tile Tidying, the Tile Maker will warn you and then eliminate tiles 257 upwards.

If you want to add some new tiles to the current set, then just do the above sequence, without clearing the tiles or setting the tile size. In this way, you will be able to add tiles on, until you run out of memory, or reach the 256 tile limit

The Load and Save tile buttons are in the Tile Maker only as a convenience, and it is better to do the loading and saving from the file menu in the main editor, which you can return to by hitting the bottom right "Return to Editor" button.

Tips for designing Tiles

When designing your tiles, try and make them as versatile as possible. If a tile can be used in more than one place in the map it will be much more useful to you, and will save you memory.

The fewer colours you use, the faster your map will update, the more memory you will save and the more colours you will have to concentrate on your bobs.

When assigning colours for your tiles, make sure that there will be enough colours available to draw your bobs, or that the colours you have used can be used for the bobs also.

Try and avoid duplicating tiles when you draw them. Although the Tile Tidy option will eliminate any duplicates, it will change the order that your tiles are stored, possibly making it a little difficult when trying to grab Briks from the selector screen.

Always make sure that the tiles start in the top left corner of the screen as this is where the Tile Maker starts grabbing from. If you offset the tiles by any amount, you will get strange results.
