Ok, I'm working on RPG server. Everything is OK, I made city with villagers and set them custom offers. But when someone trade with a villager noone else can trade with it in the sametime. So, I'm still not officially run the server but I'm sure there will be trolls who will stay AFK with open villager trade GUI. So, I want to prevent this. Any ideas? I'm searching for code for multiply trade GUIs from one villager but I found that there is no way with bukkit API. I know that I have to cancel the event in EntityInteract event and then open the trade GUI manualy but didn't find example codes for this. So I'll be grateful for some help.
