Landing spot for fixes, tuning, micro game modifications that have no other home.
This is tweak central.
Brought to you by DevotedMC, we're taking a pretty inclusive and permissive view for this plugin; if you need a particular "hack" to get things working in your use case, send us a PR for inclusion, we'd love to host it.
This plugin is designed from the ground up to support easy creation of "microplugins" -- things with featuresets too small to make sense for a full sized plugin, or fixes for game problems or simple heuristic loggers.
Making a new "Hack" is always an option, but take a look at this list of active Hacks and see if your contribution might fit with an existing module.
Any hack can be theoretically live-disabled and enabled using:
hacks <hackname> enable or hacks <hackname> disable where the hackname is
as listed.
Type hacks to see what the current enable/disable status of all loaded hacks is.
Type hacks <hackname> to see a readout of that particular hack's status or config.
Type hacks <hackname> get <configitem> to see the current configuration setting for that config element in that hack.
Type hacks <hackname> set <configitem> <new value> to set a new configuratoin value for that config element in that
hack. Not all hacks support this.
This hack offers some defence against insta-break / fast-break client hacks by denying continuous breaks.
Allows players to occasionally pick up spawn eggs of mobs they kill with Bane of Arthropods.
Stops clients from receiving extraneous entity and item data that could be exploited custom clients.
This hack allows administrators to enforce a limit on how long players can stay dead, preventing zombie scouting and safe bots.
Disables particular [potion] effects from being applied to players through standard means.
Gives administrators the ability to spawn in a wand that when right clicked on blocks and entities will display useful debug information.
This hack allows administrators to inspect an event as it passes through the stages of priority, what listeners are handling the event at what stage, and if applicable when exactly the even is cancelled.
This hack lets you search for all the events currently being listened for with your current plugin setup and those listeners' class names.
A new BasicHack (thanks Maxopoly) which encompasses a number of previously unincluded Humbug gameplay modifications. Specifically, sheep wool dying, anvil use, enchanting table use, cauldrons sourcing infinite water, disabling Ender Dragon, disabling iron farms, disabling Ender Crystal damage, disable mining fatigue, and equipping banners as hats.
Passively upgrades the lore and display name text under the hood from legacy strings to components.
This hack allows admins to regulate XP and enchantments in particular ways.
Allows administrators to regulate the behaviour of phantoms and their spawning.
Administrators can force revive a player where they died.
Allows administrators to view and set a player's statistics.
Another new BasicHack which allows control of the spawn of creatures rate from nether portals
Allows administrators to disallow boating on particular blocks.
Test hack for SimpleAdminHacks itself. Please make a fuss if you see any red.
This hack keeps track of who breaks what, and what they broke to get there. I've got bigger plans for more heuristics but for now, that's it. Please, feel free to improve on this.
An integration into CombatTagPlus, this announces to in-game operators when combat is under way. Invaluable when you like your admins to monitor in-game fights.
This is a catch-all for anything micro that has no other home. Useful features like /serialize command live here too,
but mostly its logging trackers that are great for debugging edge cases and useless for normal runtime.
The principle focus here is on enabling and disabling game features, like elytra or skulker boxes or those sorts of things. Try to keep the focus on boolean or otherwise simple on / off or discrete state options that relate to existing Minecraft game mechanics.
Sometimes things in Minecraft just... don't work. Or don't work the way you want them to. Put those fixes here.
Similar to Game Fixes, but distinct in that the intent here is on hacks that tune or alter existing mechanics without fully disabling them or without fixing them. Things like altering armor damage reduction or tool impact would be good fits.
(Removed in 1.2.4) ~~An experimental module whose complexity is approaching divorce from SAH, this is a bit of mid-work code that allows operators to define static Bots that show up like "real" players but aren't.~~
This hack allows player's to view a horse's stats.
Allows the creation of customizeable, helpful first join books that are distributed to players when they first join the server. Safe to turn off but super useful if you have a core set of additional "good to know" information or introductory material you'd like players to receive.
Host of the /invsee command, gives insight into active player inventory, armor, health and more. I hope / intend to
add another portion to this that allows online and offline inventory management via /invmod but this is as of now not
started.
(Removed in 1.3.0) ~~My hope is to remove these in time, but for 1.9 and 1.10 minecraft players go invisible all the time. Both of these hacks use different approaches to help preserve the visiblity of players. The second hack is the more invasive, sending explicit location packets when the situation indicates its usefulness.~~
A new join tracker, that also doubles as an introkit delivery mechanism. It also exposes the introkit command you can
use to send specific people a new introkit if they lost theirs.
Another useful alerting hack, sends a message to online operators when players are actively breaking reinforced containers.
This one is pretty Devoted iteration 3 specific. Allows tracking server wide of all breaks or builds under a specific Y level.
This is mature enough to be its own plugin now, but for the moment I'm leaving it in because IMHO it is an essential component for debugging and maintaining your server.
This hack begins where /timings and warmroast end. It generates in-game visualizations of per-tick time utilization, and allows you to investigate with extreme effectiveness exactly what is causing instantaneous or irregular lag. Things that average out, but lead to bad experiences for players.
To use it, there are a number of important commands.
First:
/showtimings This gives the requester a "map" object that paints a heatmap, heightmap, and linegraph of TPS. Each
vertical pixel is a full 20 ticks; each dot in the heatmap is a single tick. The heightmap above the heatmap
(heatmap is on the bottom) is both colored and sized based on time-in-tick. At the very top is line graph of
relative "health" of the tick. The closer to the grey line the better; the closer to the top, the worse./thresholdtimings This starts a very high resolution (1ms) stack inspection tracker. It keeps track per tick
with usually 50 samples per tick of which methods and classes are being taking up time within the tick. Give it a
threshold factor -- please, something more then 1, 5 to 10 works well -- where any tick that takes longer then
threshold factor * average tick length, dumps the class/method list to requestor (either console or in-game
character). The list is in sorted order of class where most time is spent down to class where least time is spent. /listtimings In you already suspect something, you can use this command to begin a spammy dump of all classes
encountered during high-resolution tracking. Only new classes are printed, and it shuts itself off if nothing new
has been printed for a full second./bindtimings This generates an in-game map displaying (like /showtimings) a heatmap, heightmap, and line graph
of per-tick utilization of any Classes that contain whatever is passed in after bindtimings. Note this is saved,
and on reload of the server if HQ timings are restarted those maps will re-bind to the saved bindings. This is a
massively useful deep inspection tool; you can put the "based" class of a suspect plugin as the parameter, and
watch its actual per-tick time utilization in real-time. Destroy the map object to release the drain on overall TPS
that results from the comparison functions used to update the map./stoptimings This turns off any HQ functions. Has the impact of pausing any bindtimings maps, and releasing all
HQ functions from impacting Tick (also stops tracking data, so data tracking will reset if HQ restarted by calling
any other HQ-tagged command).In game example with some descriptions:
A solid piece of contributed code, this hack lets player's turn on and off redstone lamps without requiring any additional redstone infrastructure.
There is room for many more hacks and the list grows regularly. The pattern is simple; check any of the existing hacks for details by example.
