Grave Add-On

With this addon, when a player dies, a grave will be placed where all your inventory will be kept, and simply to get the items, break the grave, and you will get your entire inventory.

How does it work?

When you die, you will get a key that, when placed in your hand, will tell you the coordinates and the distance in blocks where you died.
When you go to the grave, you must interact with it while having the key in your hand, and you will obtain your entire inventory.
The keys are unique and only work with the correct gravestone.
Only the owner of the gravestone can open it, regardless of whether another player has the correct key.
If for some reason you lose the key, you can craft another one.
If you fall into the void in the end dimension, the gravestone will be placed at height 1 along with some blocks to make it easier for you to obtain.
If you die in the same position as another player, the gravestone will be placed next to that gravestone.
