Give InvItem every n hours

From Second Life Wiki
Jump to: navigation, search

This script will give an inventory item on touch only every n hours, even if somebody touches the object more than once.

// Idea and written by Criz Collins
// Don't sell this FREE script!!!
 
string  giveitem    =   "name of item in objects inventory";
float   giveevery   =   24;  // hours!
