Lootr in FTB Skies 2

Same as in the All the Mons 1.3.0 guide

Lootr makes sure nobody misses out on loot. Every container that has a loot table gets its own inventory for each player who opens it, so there is no race to be first into a structure and you never open a loot chest and find someone's left-over trash.^[1]

It covers chests, trapped chests, barrels, shulkers and minecarts that have a loot table. These containers look different from the vanilla ones, and their colour changes from gold to blue once you have opened that container.^[1]

The pack ships the NeoForge build for Minecraft 1.21.1, version 1.11.38.125. The mod is currently required on both the server and the client.^[1][2]

Good to know

• Lootr only changes the containers. The loot inside is generated the same way vanilla chests generate it.^[1]
• By default, if you try to break a Lootr container you get a warning that all containers are per-player. You can still break one while sneaking, unless that option is disabled in the configuration.^[1]
• If a container from another mod does not convert, that mod may be filling it with items by hand instead of using a loot table, and Lootr cannot detect a loot table in that case.^[1]
• Loot containers that were already opened in an existing world will not be converted when the mod is added, because vanilla loot generation removes the loot table and Lootr has no way to find that information.^[1]
• To make a starter chest for everyone, fill a vanilla chest, stand on it and run the /lootr custom command. This needs operator privileges.^[1]

Lootr works differently from most mods you'll meet in this pack. You don't start by crafting anything. It changes how loot containers behave: every container with a loot table gives each player their own inventory, so nobody misses out and nobody finds someone else's leftovers.^[1]

Step by step

1. Go and open loot containers in generated structures. Chests, trapped chests, barrels, shulkers and minecarts are all covered, and each one gives you a personal inventory.^[1]
2. Look at the colour. A Lootr container looks gold, and it turns blue once you have opened it, so you can tell at a glance which ones you've already looted.^[1]
3. Try the other container types. The mod's own names include the Loot Chest, Loot Barrel, Loot Shulker and Decorated Loot Pot, plus the Item Frame with Loot and the Minecart with Loot Chest.^[3]
4. Keep an eye on the advancements. They start with opening your first Lootr chest, then climb through 10, 25, 50 and 100 opened containers. There is also one for opening one of every container type.^[3]

What this pack's config does

Loot is individual per player here, because team.team_loot is false. Item frames with items generated by structures are converted into Lootr item frames, and mineshaft chest minecarts are converted into standard loot chests, because conversion.convert_item_frames and conversion.convert_mineshafts are both true.^[4]

The pack doesn't turn on refreshing or decay for any chests. refresh.refresh_all and decay.decay_all are false, and the lists of loot tables, mod IDs and dimensions for both are empty. A chest you've emptied therefore isn't set to refill or disappear, so loot up as you explore.^[4]

Lootr changes how loot containers behave: every container that has a loot table gives each player their own inventory, so nobody races to a structure first and nobody finds a chest someone else already emptied. Supported containers are chests, trapped chests, barrels, shulkers and minecarts. They look different from vanilla ones, and their colour changes from gold to blue once you have opened them. The project page says Lootr is currently required on both the server and the client.^[1]

What counts as a Lootr container

• Block containers: Loot Chest, Loot Chest, Loot Barrel and Loot Shulker.^{[3][5][6][7][8]}
• Brushable and pot containers: Sand, Gravel and Decorated Loot Pot.^{[3][9][10][11]}
• Entity containers: the Minecart with Loot Chest and the Item Frame with Loot.^[3][12][13]

How conversion works

Lootr swaps vanilla containers for its own versions when they have a loot table. The conversion tags cover vanilla chests plus wooden chests from other mods, trapped chests, barrels, shulker boxes, suspicious sand, suspicious gravel and decorated pots. For entities, they cover chest minecarts and the vanilla item frames, including glow item frames.^{[14][15][16][17][18][19][20][21][22][23]}

Maps and filled maps are listed in the item frame blacklist tag for conversion. A long list of block entity types is also blacklisted, including furnaces, hoppers, ender chests, dispensers, droppers, brewing stands, lecterns and spawners. Lootr's own containers are on that list too.^[24][25]

If a container from another mod does not convert, the mod is probably filling it by hand instead of using a loot table, and Lootr can't find a table to use. Empty containers may just be decoration. The axe chest in the vanilla Woodland Mansion has no loot table and is not converted.^[1]

The pack's config file sets conversion.disable to false, so conversion is on. It sets conversion.convert_item_frames to true, so structure item frames with items in them are converted into Lootr item frames. It also sets conversion.convert_mineshafts to true, so mineshaft chest minecarts are converted to standard loot chests.^[4]

The Elytra item frame has its own settings in the pack's config. conversion.convert_elytras_to_item_frames is true, so it is converted into a Lootr item frame with an elytra inside. conversion.convert_elytras_to_chests is false, so the alternative of a standard loot chest with a guaranteed elytra is switched off.^[4]

A few more conversion settings as the pack's config file has them:^[4]

• conversion.tick_delay is 20. Its comment says the higher the value, the slower containers take to determine they should refresh or decay.^[4]
• conversion.max_age is 18,000 (fifteen minutes, per its comment). Entries above this age are discarded.^[4]
• conversion.save_mode is SMART. Per its comment, that defaults to ALWAYS but switches to WHEN_OPENED on aternos and exaroton.^[4]
• conversion.bypass_spawn_protection is true, so accessing a Lootr container bypasses spawn protection.^[4]

Per-player and team loot

The pack's config sets conversion.randomise_seed to true, so the loot is randomised per player instead of being the same for everyone using the provided seed.^[4]

Apart from the container itself, Lootr generates loot in exactly the same way as vanilla chests do.^[1]

The pack's config sets team.team_loot to false, so loot is individual per player. If it were true, loot would be assigned by team, using the entity's scoreboard team by default, and a player with no team would use their own UUID.^[4]

Refresh and decay

Lootr can make containers refresh (regenerate their contents) or decay (be destroyed some time after first being opened, the next time someone tries to open them). This is chosen by loot table, mod ID or dimension. In this pack every one of those lists is empty, and refresh.refresh_all and decay.decay_all are false. Out of the box, then, no container refreshes or decays.^[1][4]

If you or a server owner turn them on, the timers come from the pack's config: refresh.refresh_value is 24,000 ticks (20 minutes) and decay.decay_value is 6,000 ticks (5 minutes). With decay.replace_when_decayed false, a decayed container is removed instead of being replaced by its vanilla block.^[4]

Containers already marked as refreshing or decaying are processed during level ticks, because refresh.perform_refresh_while_ticking and decay.perform_decay_while_ticking are true. For containers not yet marked as refreshing, refresh.start_refresh_while_ticking is true, so they can be marked for refresh during level ticks. For containers not yet marked as decaying, decay.start_decay_while_ticking is false, so they are only marked for decay when next trapped.^[4]

In the pack's config, notifications.notification_delay is 600. Its comment describes this as the maximum time in ticks remaining on a chest before a refresh or decay notification is sent to a player. notifications.disable_notifications is false, so those notifications are on.^[4]

Where conversion is allowed

In the pack's config every whitelist and blacklist option is empty, covering dimensions, loot tables and mod IDs. According to the config comments, a blank dimension list allows all dimensions. whitelist.loot_table_forced_whitelist is the option that forces conversion of listed tables even if they are blacklisted.^[4]

The structure tags for blacklist, whitelist, decay and refresh in the mod's jar are also empty.^{[26][27][28][29]}

Breaking, explosions and drops

By default, trying to break a container gives you a warning that containers are per-player, and you can still break one while sneaking unless that is disabled in the config. In this pack breaking.disable_break and breaking.enable_break are false, and fake players can't break containers without sneaking because breaking.enable_fake_player_break is false.^[1][4]

The pack's config leaves explosion protection off: breaking.blast_resistant and breaking.blast_immune are false. It also leaves breaking.should_drop_player_loot and breaking.break_to_drop_loot false, so those loot-dropping behaviours on breaking are switched off.^[4]

Broken Loot Chests, trapped chests, barrels and shulkers drop the plain vanilla block, keeping any custom name. The Centennial Trophy drops itself.^{[3][30][31][32][33][34][35]}

In the pack's config, breaking.brushables_self_support and breaking.item_frames_self_support are both false, so brushable blocks and item frames are not made self-supporting.^[4]

Redstone and custom containers

The pack's config sets power.power_comparators to true, so a comparator on a Lootr container gives an output of 1 (it would give 0 if false). It sets power.trapped_custom to false, so custom inventories do not act like trapped chests when opened.^[4]

The trapped chest block entity type is tagged as trapped in the mod's jar.^[36]

You can also make your own starter chest. Fill a vanilla chest, stand on it and run the /lootr custom command, which needs operator privileges. It creates a custom Lootr inventory that looks like a chest.^[1]

Unverified The sources for this pack don't show a progression path or tiers for Lootr, and they include no quests or crafting recipes for it. Below is what the mod's data files do show.

What breaking a Lootr container gives you

Lootr's containers don't drop special Lootr items. Their block loot tables hand back the plain vanilla block, and the custom name is copied over if the container has one.^{[30][31][32][33][34]}

• The Lootr chest drops a plain Chest, and so does the Lootr inventory block.^[31][32]
• The Lootr barrel drops a plain Barrel.^[30]
• The Lootr shulker drops a plain Shulker Box.^[33]
• The Lootr trapped chest drops a plain Trapped Chest.^[34]

The trophy and the elytra table

The trophy block drops Centennial Trophy itself. The mod also has a reward loot table that gives exactly one trophy.^[35][37]

There is also a Lootr chest loot table that gives exactly one Elytra. The sources don't say where in the pack that table is used.^[38]

Structure tags

In the mod's own jar, the structure tags for the blacklist, decay, refresh and whitelist are all empty. That is the mod's default. I can't tell you whether the pack fills them in elsewhere, since the pack's other data files weren't available to check.^{[26][27][28][29]}

Lootr creates a unique inventory for each player who opens a container that has a loot table. The pack ships two config files for it, a common one and a client one. The numeric options in the pack's common file that list a mod default (maximum age, tick delay, decay, refresh and notification timing) are all set to that default value.^[1][4]

Loot sharing and seeds

• team.team_loot is false. Per the config comment, loot is then provided individually per player rather than assigned by team.^[4]
• conversion.randomise_seed is true. The config comment says this decides whether loot is the same for all players using the provided seed or randomised per player, and true means randomised per player.^[4]
• conversion.bypass_spawn_protection is true. Per the config comment, accessing a Lootr container then bypasses spawn protection.^[4]

Refreshing and decay

The refresh and decay lists (refresh.refresh_loot_tables, refresh.refresh_modids, refresh.refresh_dimensions and the matching decay lists) are all empty. refresh.refresh_all and decay.decay_all are false. The config describes blank lists as meaning no chests refresh or decay.^[4]

The timers are set to the mod default. refresh.refresh_value is 24,000 ticks and decay.decay_value is 6,000 ticks. notifications.notification_delay is 600 ticks, which the config comment describes as the maximum time remaining on a chest before a refresh or decay notification is sent (30 seconds by default).^[4]

Breaking chests

Every option in the breaking group is false in this pack, including breaking.disable_break, breaking.enable_break, breaking.blast_resistant, breaking.blast_immune and breaking.break_to_drop_loot. breaking.should_drop_player_loot is false too, so the option that makes a broken chest drop the contents of the player-specific inventory is off.^[4]

What gets converted

• conversion.convert_item_frames is true, so per the config comment, item frames with items generated by structures are converted into Lootr item frames.^[4]
• conversion.convert_elytras_to_item_frames is true and conversion.convert_elytras_to_chests is false. Per the config comments, the Elytra item frame is converted into a Lootr item frame with an elytra inside, not into a loot chest.^[4]
• conversion.convert_mineshafts is true, so per the config comment, mineshaft chest minecarts are converted to standard loot chests.^[4]
• All the whitelist and blacklist lists are empty. The config describes blank lists as not restricting anything, so this pack sets no dimension, loot table or mod id exclusions there.^[4]

Redstone and client visuals

power.power_comparators is true, so per the config comment, a comparator on a Lootr container gives an output of 1. On the client, particles.unopened_particles is true, which the config describes as particles spawning from containers the player has not yet opened. textures.vanilla_textures and textures.new_textures are both false.^[4][39]

FTB Skies 2 1.23.0 ships Lootr 1.21.1-1.11.38.126, and the mod has been in the pack since 1.0.1 or earlier. The pack changelogs have no entries for this mod, so everything below comes from Lootr's own changelogs. They are developer commit notes, so I'm only picking out the changes that matter to you as a player.^[40]

In your version (1.11.38.126)

• A "break to loot" feature was added.^[41]
• Work began on a teams system, with follow-up fixes for team resolvers and for how open status is handled when teams change.^[41]
• Problematic loot chests are now handled through a service-based system.^[41]
• The new command system was back-ported, and particles were adjusted.^[41]

Earlier 1.21.1 releases

• 1.11.38.124: a fix for an odd issue where getContainerAt returned something that wasn't a Container.^[42]
• 1.11.37.122: arrows can now break pots, hoppers are prevented from inserting into entities and blocks, and you get a message when trying to insert into item frames. The lootr_minecart name became an alias of lootr_cart. This release also added a trapped chest advancement, a fix for decorated pots with empty loot pool entries, and a fix for a Create-related duplication issue.^[43]
• 1.11.37.121: particles became more customisable, and item frames were fixed.^[44]
• 1.11.37.120: a fix for directories not being created properly.^[45]
• 1.11.37.118: the block convert blacklist now actually works.^[46]
• 1.11.36.114: a fix to the tag checker for NeoForge.^[47]
• 1.11.36.110: better Jade integration for suspicious blocks, and the trophy cutout now works on all platforms.^[48]

Older 1.21 builds

Before the 1.21.1 builds, versions 1.10.35.91 and 1.10.35.96 were released for 1.21. Version 1.10.35.91 fixed inverted logic for shulker boxes and ported the /lootr cclear command to 1.21. Version 1.10.35.96 mostly tweaked and corrected the documentation, including an explanation of what the "converters" are used for.^[49][50]
