Sounds!!!!!!!!!!!!!

[PSPKOR]

OK I've been stuck with this all weekend with no luck, can some one tell me whats wrong with this bit of code:
if playerMove == "no" and loopCount == 0 then
tankidle:play()
loopCount = loopCount + 1
loopCount2 = 0
tankdrive:stop()
end
if playerMove == "yes" and loopCount2 == 0 then
tankdrive:play()
loopCount2 = loopCount2 + 1
loopCount = 0
tankidle:stop()
end
Its playing .wav sounds and they are looped.

I did also try doing another way of playing it using the
local sound = filename
voice = sound:play()
but that didn't work very well, beacause every time I tried to stop one sound it was ok but if i tried stoping the other it just wouldn't work.

So if someone could help me out here please.

Wouldn't this be better in terms of logic flow?

if playerMove == "no" and not tankidle:playing() then
tankdrive:stop()
tankidle:play()
end

if playerMove == "yes" and not tankdrive:playing() then
tankidle:stop()
tankdrive:play()
end

[PSPKOR]

Cheers i'll just try it.

---Edit---
No, it just goes off like it did before. Any other ideas?

[yaustar]

Okay.. In that case, I need to know what it actually does and what you want it to do in as much detail as possible. How are you trying to stop both sounds?

[PSPKOR]

Well its for a tank game that I'm making and I want it so that when the tanks moving it plays one sound and when its not moving it plays the other. But i also need it so it stops the other sound, or it sounds quite nasty. The sounds are also looped.

At the moment I have this:

if playerMove == "no" and loopCount == 0 then
local sound = tankidle
voice = sound:play()
loopCount2 = 0
loopCount = loopCount + 1
end

if voice:playing() and playerMove == "yes" then
voice:stop()
loopCount = 0
end

if playerMove == "yes" and loopCount2 == 0 then
local sound = tankdrive
noise = sound:play()
loopCount2 = loopCount2 + 1
end

This plays the stoped sound fine eg starts and stops at the right time, but the driving sound just keeps playing. If I try to add the STOP() command it crashes.

[PSPKOR]

That didn't work either.
But yeah thats what I want i want it to do.
"plays either the tankidle or tankdrive sound at one time"

[yaustar]

tankdriveVoice = tankdrive:play()
tankdriveVoice:stop()
tankidleVoice = tankidle:play()
tankidleVoice:stop()

while true do

if playerMove == "no" and not tankidle:playing() then
tankdriveVoice:stop()
tankidleVoice = tankidle:play()
end

if playerMove == "yes" and not tankdrive:playing() then
tankidleVoice :stop()
tankdriveVoice = tankdrive:play()
end
end
Completely untested.

[PSPKOR]

Dont look like thats working, I'll try and fiddle about with it a minute.

Do you have a PSP or Lua player on your PC?

Nevermind here you go have a look at the code attached, this is the whole code for it so far.

The sound stuff is under ------------drivin sounds------------.

[yaustar]

tankdriveVoice = tankdrive:play()
tankdriveVoice:stop()
tankidleVoice = tankidle:play()
tankidleVoice:stop()

while true do

if playerMove == "no" and not tankidleVoice:playing() then
tankdriveVoice:stop()
tankidleVoice = tankidle:play()
end

if playerMove == "yes" and not tankdriveVoice:playing() then
tankidleVoice :stop()
tankdriveVoice = tankdrive:play()
end
end
.

[PSPKOR]

Well it runs this time but it only plays the idle sound.

PS - look at my post above.

[yaustar]

Can you zip up the entire project with the sounds for me to look at?

[PSPKOR]

OK here you go, all there.
Also L + R are like the tracks, so hold L + R to go forwards.

[yaustar]

I had a decent shot at it and to be honest I can't get it to work even though the logic appears to be fine. I honestly think that the sound system of LuaPlayer is buggy as hell and system calls like playing sound, blitting to the screen are all on seperate threads which makes them very hard to use.

Sorry.

OK, cheers anyway for your help. Not sure what to do now about SFX on the game though.

P.S- What do you think about the game(in early stages) so far.

-------------Edit----------------

Yeah!! I did it I got it to work now, its not the nicest of way to do it, but it works none the less.

thanks again Yaustar :).

In case you want to know this is how i did it -

--------Variable--------
soundCount = 0

--------Main loop--------
if gamestate == "game" and soundCount == 0 then
local sound = tankidle
voice = sound:play()
end
if gamestate == "game" and soundCount == 0 then
local sound = tankdrive
voice2 = sound:play()
end

if playerMove == "no" then
voice:volume(128)
voice2:volume(0)
soundCount = soundCount + 1
end
if playerMove == "yes" then
voice:volume(0)
voice2:volume(128)
end

Impressive hack considering what you had to work with ;).
