Eye of Cthulhu
Have you wanted to keep monsters out but not have a big and ugly iron door?
Do players keep raiding your stuff when your not around?
You can stop it all with two simple items: The key and padlock!
When you craft a padlock or key you can right click on it to rename it, they must have the same name or it will not unlock the door.
The padlock will also work on chests, trapdoors, switches, etc.
To craft a padlock you need 5 iron and to craft a key you need 3 iron.
There will be more types of locks and keys, 1 locking out enemies but not town NPCs. Sprites will come later for new locks
If there are any other threads that have the same idea as this, I did not copy them, I did google the name but I did not find anything.
