Bartender
Bartender! v1.0.0
Bartender to serve drinks.. and other things.
Drop this script in your bartender prim.
Drop a bunch of 'drink' objects into your bartender prim.
Touch the bartender prim and select a drink.
Some debugging info is transmitted on llOwnerSay, but spam is minimal. Edit the script variable to adjust this.
This script differs from others in that:
It opens a single random negative channel, it does not activate an llListen *every time* someone clicks it.
IF the random channel is being used by something else, and this causes the bartender to get a bunch of garbage inputs, it will automatically change to a new random channel, and optionally inform the owner.
Evidently this script can be used as a kind of object freebie vendor too.
NOTES:
It's been a while since I wrote it, and it was never really extensively tested, so i expect there is some stupid in it. But AFAIK it's fine.
It features a primitive kind of double-touch prevention that i don't use anymore, so I guess the touch functions have been improved.. yeah.. that was it.. i think.. yeah. So there are some redundant bits.
