Hi

This script:


class TestGC
{
TestGC @child;

~TestGC()
{
output( "Dest 1" );

child.Do();

output( "Dest 2" );
}
void Do(){}
}

void startGame()
{
TestGC @gc = TestGC();

@gc = null;



scene.RunGC();

output( "End" );
}


output:

Dest 1
End

Null pointer exception no show

As the destructor isn't necessarily called at the moment when the object goes out of scope, but only the last reference to it is released, any exception that occurs in the destructor isn't shown in the normal execution.

I'll look into how to make it possible to detect exceptions in the destructor for a future release.

I've implemented the support for having the engine request a context from the application in revision 1929.

For this to work the application needs to implement two callbacks and register them with engine->SetRequestContextCallback and SetReturnContextCallback.

With this, the application will be able to setup the context with what it needs to catch the exceptions, debug the script, etc. It can also be used to provide memory pooling for contexts, to improve performance.

Regards,

Andreas
