Adding skins to your machines is quite easy. Just add these resources to your machine dll: Resource type name description Bitmap "skin" bitmap for the machine, size must be 100x50 Bitmap "skinled" "led on" patch bitmap (if not given, default led is used) "position" "skinledpos" x and y coordinates inside skin bitmap for the led on bitmap (two bytes) "color" "textcolor" machine name text color (3 bytes, RGB) (optional, defaults to black) notes: -quotes ("") are important in the above names! -The panning bar goes from 2,38 to 97,47 inclusive. Make sure your skin design accounts for this -font is between y=20 and y=30 Some advices: - use 256 color bitmaps to save memory - led can be redrawn quite often so keep it small - if you want all your machines to use same bitmap, do not include same bitmap in each dll. instead create another dll and add following resource to your machine dlls: Resource type name description "asciiz" "skinref" name of skin dll (for example "Geonik's Skin.dll") this dll should be installed to Buzz\Gear\Skins dir.
