This is a phase door script, meaning that it “opens” by converting the prim it is in to be partially transparent, and the link set to phantom (so avatars can move through it). It’s linkable, however because the entire link set goes phantom at once, the results may be a little unexpected.
Supports detailed access control; access can be owner-only, set to group, or everyone, with support for whitelist, blacklist and manager list (can control door lock/unlock) as well. Can play a door chime noise (sample included) when an avatar clicks on it. Configuration is entirely notecard based, will full instructions included.
I also do a multi-pack of blind, phase, swing and slide scripts, which includes this script.
