I'm using the derelict fmod bindings to handle sounds in my
application and I'm running into a weird bug... If I put calls to
fmod in a function inside a class, upon calling those functions
the instance of that class will be null, or otherwise changed. I
obviously get an access violation if I try to do anything with
that instance of the class while it's null.
class Audio {
FMOD_SOUND* audio;
FMOD_SYSTEM* fmod;
this(){
//initialization code
}
void load(string path){
FMOD_System_CreateSound(fmod, path.toStringz, 0, null,
&audio);
}
}
Audio a;
void main(){
writeln(&a); // 281478
a = new Audio();
writeln(&a); // 281478
a.load("audio.ogg");
writeln(&a); // null
... //some time later
writeln(&a); // 281478
}
It happens even when I rearrange example code to be inside a class
https://github.com/Extrawurst/DerelictFmod/blob/v4.1.0/source/app.d
The calls work and don't return an error code. I can play music
as long as I load and play within the same function call. Just
the surrounding class reference gets messed up? And if I check
later in the program the instance will return to its former value.
I'm using Windows 7 x64. Just updated to the latest DMD version.
I'm compiling as an x86 Windows application. Got the most recent
bindings and dlls.
I don't understand what's making this happen... any help would be
very much appreciated.
