Hello,
This is an issue I've had to hack around before. The best way I've
found to fix it is to convert all of your objects to object handles.
item@[] lookup(string keyword)
It might be a bit of work, but its so much better to use handles
anyway that you won't regret it.
In fact, I would probably write the line
item@[]@ lookup(string keyword)
such that we are not only using an array of handles, but we're
returning a handle to the array itself.
You also really can't take proper advantage of inheritance with out
using handles.
If this is beyond your current knowledge of BGT, I suggest researching
handles, if not also inheritance. Handles are amazing things that will
probably make your game run faster, too!
Best,
Aaron
