I have user data objects with metatables that implement __index and
from a lua coder's pov, the user data is an OOP object. they can:
obj:Call() to call a method
obj.x = 4 to get/set values
what I'd REALLY like to do is allow a method call on a non existent
method to be a no op
would do nothing and lua execution would continue. Currently lua stops
and says "attempt to call nil method (BadCall)"
I know that BadCall invokes __index to find BadCall and that I could
instead of returning nil, return a function that does noting (acting as
a no op).
But then that breaks the getting/setting of values as obj.x (where x
doesnt initially exist as part of the userdata's metatable), which
normally gets instantiated in the __newindex, now is found to be the no
Not quite what I wanted!
can anyone think of how to accomplish this?
Thanks as be the norm!
