Hi i want to do a casino and i want to use a hopper for the players to put the payment in, can they steal from hoppers, or is there a way to make it so i can use a chest and they open the chest to put the payment in ?!
To be fair, now you can't edit someone else's island anymore like you could in the past ( Unless you trust them/ invite them, but whatever) So hoppers shouldn't be a problem anymore. They just remain disabled from a time where they were a problem.
It means if you try to place a hopper, the game will put it back in your inventory. Keep in mind you can still make hoppers, (at least I am pretty sure can, I haven't tried for obvious reasons) but if you place them, some plugin will stop you.
Hoppers are disabled on Net for duping and looting reasons. As for your casino, since you are the player working the casino there shouldn't be a problem with players just dropping the items to you directly. Has your question been answer?
