the ground gets the jitters

[+hloberg]

I'm using DLC+

I have this little routine below that makes a explosion sound when a ship is hit. I have seen people use DRAWSCREEN as a delay otherwise the sound effect is so fast it can barely be heard.

Problem is that the playfield jumps up ad down while the sound effect is going on. this seems to only happen in DLC. use multikernal and the effect does not happen.

question is there a more elegant delay i can use for the sound effect so that I won't have to use the bouncing playfield delay?

 

 

AUDV0 = 8
AUDC0 = 8
AUDF0 = 8

drawscreen
t1=0
_sndcnt1

drawscreen: rem this causes the playfield to jump up and down in DLC+

t1=t1+1:if t1< 25 then goto _sndcnt1
t1=0

AUDV0 = 0

Not a direct answer to your question. Using drawscreen to delay a sound sounds like overkill and it looks like it's problematic.

 

You could use a counter variable instead and activate the sound as needed.

main
 counter = counter + 1
 if counter > 240 then AUDC1 = 2 : AUDV1 = 4 : AUDF1 = 3

I presume you mean DPC+. Sounds like you're encountering an issue asked about in this topic, to which the answer is:

Are you setting the DFxFRACINC registers in the main loop, right before the drawscreen command? Drawscreen messes up the values, so you need to set them each frame. Otherwise the game can jitter with certain values, IIRC.

Have you seen my Sound Effect driver for bB?

thanks, DFxFRACINC fixed the jitters. I also try out your sfx package.
