This mod adds some new (unbreakable) blocks. You can use this mod to make your house or building (almost) impossible to pass (for people with no chorus fruit lol).
It'll add the following blocks:
- Password Block
First provide a password, and nobody will be able to pass without the password ever again.
- Key Card Maker
Use this to create Key Cards, you need to put a keycard into the slot, and then you can change the data of it. ONLY NUMBERS!!
- Key Card
Used to store the codes using Key Card Maker, and open KeyCard readers.
- Key Card Reader
To configurate, you only need to right click it with your keycard, (you've made using the Key Card Maker) and then you can only activate the reader using the same card or another card with the same NBT
