NULL resource" error

#1 I don't think Torque can play mp3s, at least I have always used either wav or ogg. Audacity is a good and free audio app that can convert between these among other things.

The reason to use wav/ogg is those are open source formats and mp3 is not.

#2 Thats correct, Torque cannot play mp3 files.

#3 Thanks for suggestions. Downloaded Audacity and converted mp3 --> ogg. Still no music. Checking main.cs and audioDatablocks.cs files. What are the typical newbie errors?

#4 Make sure your AudioDescription and AudioProfile are getting created successfully. Make sure you have the appropriate AudioDescription if it is a 2D or 3D sound. If it is a 3D sound and you don't specify a position for it to play it will play at 0,0,0 which means you won't hear it.

#5 Saturday, tried both ogg and wav files. Rechecked main.cs and audioDatablocks.cs, especially AudioProfile and AudioDescription. Watched Console for errors and fixed cs files. But didn't hear TGB play any sound.

How would one know that AudioProfile and AudioDescription are getting created successfully?

So far, TGB has played only its built-in sounds. It has never played original sounds copied into the game/data/audio directory. Is there someplace else that audio files are referenced? Is there a procedure that needs to be followed when importing audio files?

#6 How would one know that AudioProfile and AudioDescription are getting created successfully?

Try typing one of these in the console..

echo(isObject(YourProfile/Description))
YourProfile/Description.dump()

Is there a procedure that needs to be followed when importing audio files?

Not really, sounds like you are doing the right things.

#7 TGB is playing sound. I had overlooked the game.cs file.
