Need help with a thinglight and sound.
2002-08-03, 5:30 PM #1
I'm trying to make it so that this cog plays one of the four wavs whenever the light flickers to the highlight, but i can't seem to get it to play the sounds.
I tried 'PlaySoundThing(rand()*sound);' but i got a bunchload of syntax errors, and I'm not to cog-literate, so any help would be appreciated.
Code: 
# Jedi Knight Cog Script
#
# Made by Stormtrooper
# modified from 00_thinglight.cog
# [YB]
#
# NOT Supported By LucasArts Entertainment Co.
# Script that causes the light value attached to a thing to flicker between two values
# (Stormtrooper-added sound thing to make a lightning-thunder effect)
symbols
thing		lightthing	desc=thing_to_light
sound		sound0		desc=lightning_sound
sound		sound1		desc=lightning_sound1
sound		sound2		desc=lightning_sound2
sound		sound3		desc=lightning_sound3
flex		lowlight=0.1	desc=off_light_val
flex		highlight=0.6	desc=on_light_val
flex		offmax=0.5     	desc=max_off_interval
flex		onmax=1.0	desc=max_on_interval
message		startup		
end

# COG Section
code
startup:
	while(1) {
		thinglight(lightthing, lowlight, 0.0);
		sleep(rand()*offmax);
		thinglight(lightthing, highlight, 0.0);
		PlaySoundThing(sound, lightthing, 1.5, 10.0, -1, 0x10080);
		sleep(rand()*onmax);
	}
	stop;
end

Use sound0[rand*4] in PlaySoundThing(); [http://forums.massassi.net/html/wink.gif]

I changed 'PlaySoundThing(sound, lightthing, 1.5, 10.0, -1, 0x10080);' into 'PlaySoundThing(sound0[rand*4], lightthing, 1.5, 10.0, -1, 0x10080);'
It plays the first sound, then crashes the game. any idea on how to fix this?

Change "rand" to Rand() - those parentheses are needed. For shame, Pilot. [http://forums.massassi.net/html/tongue.gif]

Also, you're using a sound volume of 1.5, but the volume is only a 0 to 1 flex.

GREAT!!!! thank you, it works now.

Now, how would i make it so that the volume is randomly between 0.2 and 1?
Something with 'flex minvolume' and 'flex maxvolume' and then PlaySoundThing(sound0[Rand()*4], lightthing, Rand()*1, 10.0, -1, 0x10080);
maybe?

OK, last thing, hopefully, The sound sometimes plays before the light flashes, so how would I make the sound wain about half a second.

The sound plays before the high light is set? Try changing your wav and see if that fixes it. It might be that the sound you're using is still playing when the next sound should be played.

Rand() returns a random number between 0 and 1. For a random number between 0.2 and 1, use Rand()*0.8+0.2.

Thank you very much, i had forgotten to delete a cog when i put the new one in, and that was what was making the thunder before the lightning.
