After I followed your code I got this error:

I'll look into this.
You said 'This is no better than the former non-ref version.' If I want to
use ref-object to return values (GetPosition), how can I get it ?
C#
[MethodImplAttribute(MethodImplOptions.InternalCall)]
public static extern void GetPosition(string name, ref Vector2 o)
C++: still doing like this ?
void GetPosition(MonoString* ms, MonoObject** mo)
{
Vector2 pos = *(Vector2*)mono_object_unbox(*mo);
pos.x = xxxx; // Returned to the caller
pos.y = xxxx;
}
void GetPosition(MonoString* ms, Vector2 *vector)
{
vector->x = ...
}
It assumes that you have a C/C++ Vector2 declaration
that is fully layout-compatible with the managed version.
