When running this code:
[monkeycode]Strict

Import mojo

Function Main:Int()
New MyGame()
Return 0
End

Class MyGame Extends App
Field snd:Sound

Method OnCreate:Int()
SetUpdateRate(30)
snd = LoadSound("itdoesntmatter")
If snd = Null Then Error "snd is null!"
Return 0
End

Method OnUpdate:Int()
Return 0
End

Method OnRender:Int()
Cls
PlaySound(snd)
Return 0
End
End[/monkeycode]

I would have thought the Error would be raised, but it looks like LoadSound doesnt return a null like LoadImage.

I agree it would be better if the return value was null for an invalid path. Or something like the (undocumented) Image.Loaded() method.

I switched most of my resources to async loading and I feel for async it's even more important to check if a resources is actually loaded.

With images I do something like
[monkeycode]
Method OnLoadImageComplete:Void(_image:Image, path$, source:IAsyncEventSource)
image = _image
If image = null Then Print("WARNING: could not load async image resource " + path)
End
[/monkeycode]

The same for If sound = null doesn't work because it sound is never null at that point in the programme code.
