Re: New game using DHS Demo System

Hi Matt,

Well done! I just tried it on my Falcon and it's very nice and polished game, so congrats for your efforts!

I'd just like to leave a few comments/observations here:

a) I played it with keyboard only so I can't comment on the other modes. But at least there I had to press space to drop the piece instead of down that's usually customary (at least in all the games of this type I've tried). Probably not a biggie but it did confuse me a bit. Maybe I'll just edit the source and re-assemble :).
b) Sound effects didn't work on my Falcon either (TOS 4.04, 14Mb)
c) I tried to take a peek at the sources to see if I can spot the problem but it seems that sfx.s is not in the archive or git :)
d) I notice you play a .mod file rendered to mp2. This might have something to do with the sfx not playing if the sound system is not reset after switching between music/sfx mode. But since the DHS falcon system already includes a mod player (sys/dspmod.s) I would suggest you switch to using that. Also there's the added bonus of it supporting up to 4 channels of sound effects while the music is playing (go to sys/dspmod.s line 268. In that line the volumes for each channel are set up, so if you put a $7fff instead of 0 as fifth value you enable the channel. Then you have to init and play the mod and then load some magic values and call dspmod+56 in order to play a sample).
e) Another thing I noticed is that the game has only 3 or 4 different speeds, with the last one being suicidal. Maybe you could introduce some "fractions" in your movement? i.e. with 0.5 pixels/vbl speed it'd move the piece every 2 vbls but with 0.3 every 4 vbls with 0.2 carry and then after 3 vbls etc. That way you can get different movement speeds without much problems.

I guess that's quite a lot :). I'd have told you these on IRC but you weren't around. Let's chat things up there if you're up for it - I'd just like to jot these down before I forgot about them!


Again, congrats!
