About this Mod
What is Oh My Vault!
In vanilla minecraft trial vaults can be opened only one time for player. A lot of people think that this should not be the case. This datapack/mod solves the problem and enables reusability of all the vaults!
With Oh My Vault! you can use the same vault all the times that you want, say goodbye to long and tedious trial chambers hunting!
Features and functionality
Go near a vault with a trial key in your main hand to instantly refill it!
If a trial key or an ominous variant is detected in the main hand the mod checks in a 3x3x3 cube area where the player is in the center, so be sure to stay close to the vault!
After that it deletes the server_data.rewarded_players[0] so the vault "forget" about the player and can be used again
A sad opened vault

We can refill it just standing near with a key!

Let's open the vault again right clicking with the key

Technicality and compatibility
"Oh My Vault!" it's a small project and it's available in a datapack and in mod version, it's vanilla compatible and can be used with my other mod deadly deadly dungeon.
As long other mods do not replace vaults or change them in critical ways this mod should be compatible with almost everything.
The mod is server side, so if you want to play multiplayer it must be installed in the server.
IMPORTANT: In very large servers (e.g. 100-200 players) the mod can "slow down" to prevent lag, so checking can take some seconds
