LenientDeath (NeoForge 1.21.x, 1.21-1.21.11)

NeoForge port of Fabric mod JackFred2/LenientDeath.
This project was developed with extensive use of AI-assisted programming and code refactoring, including but not limited to code generation, debugging analysis and documentation writing.

In-Game Commands

All commands require OP permission (level >= 2). Unless otherwise noted, set commands take effect immediately and are auto-saved to the current world’s serverconfig/lenientdeath-server.toml.

Set Config Values

/lenientdeath config set <key> <value>

All available keys, value types and descriptions:

Examples:

/lenientdeath config set enabled false
/lenientdeath config set voidRecoveryMode ALL_DROPS
/lenientdeath config set privateHighlightScanRadius 128.0

Get Config Values

/lenientdeath config get <key>

Supports all keys listed above. Numeric keys display their allowed range; enum keys display all valid options.

Examples:

/lenientdeath config get voidRecoveryMode
/lenientdeath config get privateHighlightScanRadius

Reload Config File

/lenientdeath config reload

Re-reads serverconfig/lenientdeath-server.toml from the current world and applies changes immediately. Useful after manual file edits without restarting.

Always-Preserve List

Manage always-preserved item IDs and tags. Items on this list are always kept on death, regardless of other rules.

Always-Drop List

Manage always-dropped item IDs and tags. Items on this list are always dropped on death; this overrides preservation rules.

Debug

/lenientdeath debug status

Prints runtime debug info including: reflection accessor status, number of players tracked by private highlight, debug logging toggle state, cached preserved-items and inventory snapshot counts, and pending death coordinate messages. Useful for troubleshooting mod issues.

How To Modify Configuration

Runtime config file path (per-world):

<world>/serverconfig/lenientdeath-server.toml

It is recommended to edit this file while the game/server is stopped, then restart to ensure all changes take effect. Alternatively, edit while running and use /lenientdeath config reload to apply.

Quick Steps

If no config file exists, run the client or server once to auto-generate defaults.
Open <world>/serverconfig/lenientdeath-server.toml.
Modify values under [General], [Randomizer], [NBT], [Features], [Features.DroppedItemGlow], [Features.ExtendedDeathItemLifetime], [Lists], [ItemTypes] as needed.
Save and restart, or run /lenientdeath config reload in-game.

Legacy Config Migration

If a legacy global config config/lenientdeath-common.toml is detected, its contents are automatically migrated to the current world’s serverconfig/lenientdeath-server.toml on first world load and applied immediately.

Full Configuration Example

[General]
# Master switch for preserving items on death
enabled = true

[Randomizer]
# Random preservation for items not matched by other rules
enabled = false
# Base random keep chance (percent, 0-100)
chancePercent = 25
# Luck additive factor (percent): each luck point adds this to chance
luckAdditive = 20
# Luck multiplier factor: formula = chance * (1 + multiplier * luck) + additive * luck
# Example: luck=2, multiplier=1.0, additive=20%, chance=25% -> 25%*(1+2)+40%=115% -> clamped to 100%
luckMultiplier = 1.0

[NBT]
# Preserve items with a specific NBT boolean tag (soulbound-like)
# Example: /give @s diamond{Soulbound:1b} -> always preserved
enabled = false
nbtKey = "Soulbound"

[Features]
# Show death coordinates in chat after respawn (with dimension)
deathCoordinates = true
# Private owner-only glow highlight for dropped items
itemGlow = true
# Private highlight scan interval in ticks (1-200), 10 = every 0.5s
privateHighlightScanIntervalTicks = 10
# Scan radius in blocks (8.0-256.0)
privateHighlightScanRadius = 96.0
# Max item entities processed per scan (16-4096)
privateHighlightMaxScannedEntities = 256

[Features.DroppedItemGlow]
# Who should see the glow: DEAD_PLAYER / DEAD_PLAYER_AND_TEAM / EVERYONE
glowVisibility = "DEAD_PLAYER_AND_TEAM"
# When glowVisibility is DEAD_PLAYER_AND_TEAM and the dead player has no team,
# show outline to all teamless players?
noTeamIsValidTeam = false

# Make death drops invulnerable to all damage
itemResilience = false

[Features.ExtendedDeathItemLifetime]
# Whether to modify death drop item lifetime
enabled = false
# Lifetime in seconds (ignored if neverDespawn is true)
# 300 = 5 min (vanilla), 900 = 15 min, 1800 = 30 min
deathDropItemLifetimeSeconds = 900
# Never despawn; clean up: /kill @e[type=item,tag=LENIENT_DEATH_INFINITE_LIFETIME]
deathDropItemsNeverDespawn = false

# Recover items from void to safe position
voidRecovery = true
# Recover items from fire/lava to safe position
hazardRecovery = true
# Void/hazard recovery scope: DEATH_DROPS_ONLY (default) or ALL_DROPS
voidRecoveryMode = "DEATH_DROPS_ONLY"
# Restore preserved items to their original inventory slots
restoreSlots = true

# --- Void Recovery Rate Limiter ---
# Time window for counting recoveries (ticks, 1-1200)
voidRecoveryWindowTicks = 10
# Max recoveries inside one window (1-100)
voidRecoveryMaxRecoveries = 3
# Cooldown after hitting limit (ticks, 1-1200)
voidRecoveryCooldownTicks = 10

# Note: voidRecoveryDebug is a runtime-only flag (not saved in config).
# It resets to false on each world load. Enable via: /lenientdeath config set voidRecoveryDebug true

[Lists]
# Always preserve these exact item IDs
alwaysPreservedItems = ["minecraft:totem_of_undying"]
# Always preserve items matching these tags
alwaysPreservedTags = ["minecraft:logs"]
# Always drop these exact item IDs
alwaysDroppedItems = ["minecraft:diamond"]
# Always drop items matching these tags
alwaysDroppedTags = ["minecraft:planks"]

[ItemTypes]
# Enable item type rules (PRESERVE / DROP / IGNORE per type)
enabled = true
helmets = "PRESERVE"
chestplates = "PRESERVE"
leggings = "PRESERVE"
boots = "PRESERVE"
elytras = "PRESERVE"
shields = "PRESERVE"
tools = "PRESERVE"
weapons = "PRESERVE"
meleeWeapons = "IGNORE"
rangedWeapons = "IGNORE"
utilityTools = "IGNORE"
fishingRods = "IGNORE"
buckets = "IGNORE"
enchantedBooks = "IGNORE"
totems = "IGNORE"
blockItems = "IGNORE"
spawnEggs = "IGNORE"
arrows = "IGNORE"
food = "PRESERVE"
potions = "PRESERVE"
curios = "PRESERVE"

Preservation Rules

Items are evaluated on death in the following priority order:

NBT Tag: Items with the specified boolean key in CustomData (default Soulbound:1b) are always preserved. Requires [NBT].enabled = true.
Manual Lists: Items in alwaysPreservedItems/alwaysPreservedTags are always preserved; items in alwaysDroppedItems/alwaysDroppedTags are always dropped (drop takes priority over preserve).
Item Type Rules: Categorized by armor, tools, weapons, food, potions, Curios, etc. Each type can be set to PRESERVE, DROP, or IGNORE.
Random Preservation: Items not matched by any rule above are randomly kept based on base chance + luck modifier. Requires [Randomizer].enabled = true.

Recovery Mechanics

Void Recovery (voidRecovery): When dropped items fall below the world’s minimum height, they are teleported to a safe position.
Hazard Recovery (hazardRecovery): When dropped items are on fire or in lava, they are teleported to a safe position.
Safe position selection order: player historical safe point -> nearest valid 3D landing spot -> near world spawn.
voidRecoveryMode controls scope: DEATH_DROPS_ONLY (default, death drops only) or ALL_DROPS (all drops).
Rate limiting: voidRecoveryWindowTicks, voidRecoveryMaxRecoveries, and voidRecoveryCooldownTicks prevent excessive recoveries in a short period.

Other Features

Private Highlight (itemGlow): Death-dropped items glow only for the owner (or teammates/everyone, configurable via glowVisibility). The glow color changes based on remaining lifetime: blue (>5min) -> green (3-5min) -> yellow (2-3min) -> orange (1-2min) -> red (30s-1min) -> flashing red (<30s).
Item Resilience (itemResilience): Make death-dropped items invulnerable to all damage (fire, cactus, explosion, etc.).
Extended Lifetime (extendedLifetimeEnabled): Extend death drop item lifetime beyond vanilla 5 minutes, or make them never despawn.
Death Coordinates (deathCoordinates): Death location and dimension shown in chat upon respawn.
Slot Restoration (restoreSlots): Preserved items are automatically placed back in their original inventory slots.
