No Free Deaths: Better keepInventory

Adds consequences to dying with `keepInventory`. Players don't abuse death as a free teleport and hunger reset mechanic when they have no reason to. ### Features - Can be disabled per-player by admins - Players will respawn at half hunger - Players lose some or all XP on death - Players lose Curse of Vanishing items on death (requires 1.20.5+) - **Not enabled by default:** Players will respawn with less health - Does nothing if `keepInventory` is disabled - Pick whether players recover all their XP ### Opt-out Players can be opted out of the consequences if they would prefer a more relaxed gaming experience. Per-player opt-out means _everyone_ can play how they want to. An admin must be the one to run the command. ``` /execute as USERNAME run function no_free_deaths:cmd/opt_out ``` ### Configure Every penalty for death can be toggled individually: ``` /function no_free_deaths:cmd/toggle_drop_xp /function no_free_deaths:cmd/toggle_curse_of_vanishing /function no_free_deaths:cmd/toggle_respawn_hunger_penalty NOT ENABLED BY DEFAULT /function no_free_deaths:cmd/toggle_respawn_health_penalty ``` The percentage of levels lost on death is set automatically when the data pack is loaded and will not be changed unless it is manually updated. It's a bit verbose, but can be changed to a custom amount e.g. `90` to lose 90% of levels. ``` /scoreboard players set .drop_percentage no_free_deaths.drop_xp.settings 90 ``` Instead of dropping a portion of your XP, you can run the following command to toggle dropping as many experience points as it would take to get you from 0 levels to your current level. Enabling "drop XP in full" means players will always drop all their XP, but it can be entirely recovered. ``` /function no_free_deaths:cmd/toggle_drop_xp_in_full ``` This data pack enables `keepInventory` the first time it is loaded. If `keepInventory` is disabled after that, it will not be re-enabled on load.
