SGrave

Graves are generated on death and store the dropped items inside, so nothing is scattered on the ground. The mod is a data pack packaged as a mod, and it works without changing the game's code. Graves are mostly invulnerable, so lava and explosions do not destroy the items inside. A grave glows and can be seen through walls, and a player can walk through it because its hitbox does not block movement. A default grave despawns after 90 minutes, and the config allows a 45 minute despawn instead.

After a grave spawns, the exact location is announced to the player in chat, in a notice that includes the grave's ID and the player's name. The grave ID matters when several graves exist, and a missing ID or name is a reason to report the problem. When a player reaches the location, a head lies on the ground with a text display showing the grave's ID and design. A grave is broken by sneaking and left clicking where the items drop.

The config includes a command that locates a grave by its position in the history: value 1 for the last grave, 2 for the second last and 3 for the third last. Players and operators can use the command. The mod can be configured in many ways and can run alongside other data packs. It is compatible with plugin loaders such as Spigot and PaperMC, and the author notes that the following game rules must be set for graves to work as described. The mod is completely free and is released under the Creative Commons Attribution Non Commercial No Derivatives 4.0 license.
