No, when you give candy to someone you get one point and the receiver gets one point, and you get given a candy so as long as you have one candy, you will always get a new one after giving one to someone else.
This is just a little suggestion, maybe the mobs which spawn could give you a point if you kill them, as there is a finite amount of people but these mobs can spawn anytime and then the mob spawning could be decreased so there isn't a huge amount of points being given out.
Mob spawning is tied into other town events so we won't go changing them. The game is not 'who can stand around and grind mobs all day.'. It's designed to have everyone interact with others, as you would interact with your neighbors when going trick-or-treating. If your SMP is a little quiet, you can go visit the other SMPs and meet new people =)
Also, will haunted candy be reactivated or no. It's very useful for the buffs it gives and it not working kinda sucks.
I hope so. The only downside to it, is that you can't chat with it open. The intent is that people agree on a trade before it is opened up Making a perfectly safe way to exchange items without the issue of, who makes the first move.
Maybe add some "buttons" which tell the other guy: Other person request more, or other person request less. Something like that, so like a communication system as you said
That's an interesting idea! Like some toggleable buttons on the bottom indicating a few preset 'messages'. I really like that idea.
Sound the same as when you screwed up the hostile mob path finding. Where if it went up to 300 hostile mobs trying to path find the server would just crash.
