The CreateInvisibleInside() python plugin function does not seem to be getting built in the plugin although the code is there. Whenever I try to use this function I get the module has no attribute error. I have tried using SetInvisible which kinda works, but only when the object is dropped out of player inventory (where I am creating it initially with CreateObjectInside). All the functions I have tried out seem to work except this one (although I have by no means tried them all out). Since I don't want the object to be seen (except by the inventory checkers and the remove function in the script) just to simplify this housing thing for the moment. I suppose I will try using a force or something instead of a key (although I did like the key - any ideas on making it non pickable but visible in the inventory?) I looked for the old Guile plugin functions documentation since the python functions are supposed to cover them off and there is scant documentation for the python - but I could not find any. Other than this I am pretty impressed by it in general. it is pretty easy to figure out large parts of it (when you can pull apart someone else's code (thanks Joris). Good stuff I rank it up there with the Java editor for extreme usefulness to content development.
