Hi all, I have this idea and was hoping you could perhaps help. What I'd like to create is essentially a tipjar anyone can donate money to. But what I want it to do is on a set interval, pay out the cash content randomly amongst the nearby people. I'm assuming this could be achieved by combining a coupe of rather simple scripts but I'm really new to scripting so don't know where to start. A bonus feature that would make it even better, is if the random selection could be done only within a specified audience so for example a sign-up through a dialog box when clicking or similar. So I could for example have individuals X, Y and Z in the room. All can donate. But only Y and Z have signed up for the random draw so only they can "win", not X. Is this doable? Reasonably simple? Appreciate any help! Thanks!
