Why angelscript doesn't call Release( ) ?
Author
r = engine->RegisterObjectType( "Matrix2", sizeof( ScriptMatrix2 ), asOBJ_REF );
r = engine->RegisterObjectBehaviour( "Matrix2", asBEHAVE_FACTORY, "Matrix2 @f()", asFUNCTION( ScriptMatrix2DefaultFactory ), asCALL_CDECL );
r = engine->RegisterObjectBehaviour( "Matrix2", asBEHAVE_FACTORY, "Matrix2 @f(float, float, float, float)", asFUNCTION( ScriptMatrix2Factory ), asCALL_GENERIC );
r = engine->RegisterObjectBehaviour( "Matrix2", asBEHAVE_ADDREF, "void f()",asMETHOD( ScriptMatrix2, AddRef ), asCALL_THISCALL );
r = engine->RegisterObjectBehaviour( "Matrix2", asBEHAVE_RELEASE, "void f()", asMETHOD( ScriptMatrix2, Release ), asCALL_THISCALL );
// AS Code :
Matrix2 m( 0, 0, 0, 0 );
But it had memory leak, Release of Matrix2 didn't been called.
I dont't know why, Thanks very much guys !
Can you show us the implementation of the ScriptMatrix2 class, and the factory functions? The problem is most likely with the implementation of the class and or factory functions.

Where do you initialize the refCount? You must set the refCount to 0 in the constructor before you call the IncreaseRefCount() method.
That's the only problem I could see.
Have you tried debugging the code? When the factory functions return the reference counter should be 1, to account for the pointer that is being returned.

I use Matrix2 matrix, without parameters, nothing memory leak happened. Release( ) functions is called. But with parameters, Release( ) is not called.
refCount is zero value when Factory Functions call. Initialize between class Construction.
Is other problem in my code ?

Just saw your problem. You're using the generic calling convention incorrectly.
This is what it should be:

This is what it should be:
static void ScriptMatrix2Factory( asIScriptGeneric* gen ){ ScriptMatrix2 *mtx = new ScriptMatrix2( gen->GetArgFloat( 0 ), gen->GetArgFloat( 1 ), gen->GetArgFloat( 2 ), gen->GetArgFloat( 3 ) ); *(ScriptMatrix2**)gen->GetReturnPointer() = mtx;}Regards,
