Rocks'n'Diamonds

it seems that it's ok to do small self-promotion here, so why not. ;-) this is cross-post from Arno's BD forum, i hope it's ok.

Miho Dash is BD-compatible engine written in Miho Scheme. because i needed something to test my Scheme implementation with, and why not BD? ;-)

it features:

• support for almost all objects from GDash.
• BDCFF loading (of course).
• database with all games from GDash (in exported BDCFF format).
• cave statistics: the program records each cave play attempt, the outcome (died, finished, skipped, etc.), cave score, collected diamonds, and so on.
• automatic engine-independent replay recording: every finished cave run is automatically saved.
• quicksave and quickload: you can save current cave state, and reload it if you did something wrong.
• single-step mode, so you can record "perfect replays". ;-)
• some configurable special effects, like camera shaking on explosions.
• tile recoloring using HSL color scheme, based on cave hash (i.e. each cave always has its own color).
• user can attach personal comments to games and caves. it is also possible to rename games and caves while keeping the original BDCFF intact.
• all caves are hashsummed (map only, map and gameplay options), so it is easy to find duplicate caves. it was done because i wanted to know how many different caves are there. ;-)
• proper handling of "left+up" and such keys: Rockford will go in zigzag pattern instead of preferring the single direction.

planned features:

• cave editor which will record editing commands (a-la BD1/BD2 engines), featuring "tree undo" feature.

the novel feature of Miho Dash is engine-independent replays: the engine records all game board changes and important events (sound played, something exploded, etc.). it is possible to replay demos without the full BD engine implementation: you only need to know how to draw various objects. this is much more flexible than simple movement recording (but a lot bigger too — one replay takes about 30-100 kb). documentation on the replay format will be included with the released game source code.

i am working on the tech demo build.

p.s.: ah. the game is GPLed. Miho Scheme may be FOSS-ed later, i haven't decided yet.

and now some screenshots…

Perfectly fine!
