I have searched a bit on the forums but can't seem to find what is wrong.

First, I load all the sounds.


Then, for every update i position them and position the listener.(I use third person)



First, I want to position the sound to the place of my character, as it is his walking sound. Then position the listener, and rotate the listener to be facing the character, as the camera is.

But as I walk arround, the sound seems to be coming from different places. If I walk to one place, it's from the left and one place from the right. It should be the same, no matter where I am in the map. What am i doing wrong?

Seems to me like the sound isn't moving along with the characters. Any ideas?

Thanks

3d Sound needs to be a single channel wave file - not a stereo one. This has goofed me up before.

Use MONO sounds - not ones with left and right channels.

Also note - there is sound scale, lister scale I think its call - and volume settings to play with obviously that could be killing you too.

Thanks for your help. Although after looking that up, it WAS a mono sound. Any other idea?

Bummer.

Quote: "Any other idea?"

Lots of experiments with Volumne, Positioning the listener, changing the listerner scale, try making a test app - with "ground" you can fly a camera around.

Load a 3dsound and loop it , and position it at 0,0,0. Put a CUBE there too so you can SEE where the sound is supposed to be.

Each loop - move the listener to the same position as the camera. Don't move the sound for this test - just the listener. You might need to Point the listener to the same angles as the came to but I foget if you can point the user's "head" or not.

That's kinda how I do my testing.

Why are you giving dbRotateListener an object position as your parameters?? That won't make it face the object. In fact, if the object has a Y position of 0, then your listenere is probably facing down or up.

LOL

Go Look at how I Do it. I have a complete Project for you to play with and it has 3d sound

(I meant use the object for a visual - place the sound where the object is. This way when you fly near the object YOU SHOULD hear the sound - you'll know you're near it if you place the sound WHERE the object is. The LISTENER should be placed at your camera position)


Check this out - See Link in First Post:

Look at the code. I rotate the Listener to the objects position, as the sound is coming from his position. So that my listener will be facing where the sound is coming from, as my camera is doing all the time.

To jason p sage:

I'll have a look at your code, thanks

I checked and downloaded, but it is for DarkBasic, right? I don't have that, I use Visual C++

Edit:

Tried the game though. Very nicely done I'm impressed

Well - the commands are very similiar. That download comes with an EXE - so you can see in action - then you can look in IISounds.dba to see how I loaded stuff and set it up - then look around for commands like POSITION SOUND (Which I do when updating the TANK position for example)

I REALIZE you MAY be running into a DarkGDK quirk - as I have not done any sound in DarkGDK really yet - but I would like to think this is unlikely.

I think i actually fixed it, and it was embarrisingly easy.

I thought that the RotateListener would rotate the listener to an assigned point, although that was not the case. It rotates objects to an assigned degree. See code:
