Paper Fight Bot (PvP Bot)

FightBot 6.0.19

Released as two builds with the same features: FightBot (6.0.19) for Paper and Purpur, and FightBot for Spigot (6.0.19-spigot) for Spigot and CraftBukkit 26.1+.

Changes

- The join greeting is now `messages.author-notice`. It only goes to FightBot's author, Funnyfam14: when he joins, he's told privately that the server runs FightBot, with its version, how many bots there are and any update waiting. Nobody else sees it, it gives no permissions and nothing leaves the server. Set messages.author-notice: false to turn it off. The old messages.greet-players list is gone; if you'd turned the greeting off or taken him off that list, it stays off.

Upgrading

FightBot updates itself. The new version downloads automatically and is installed the next time the server restarts. If you've turned automatic downloads off (updates.download: false), download the new jar and replace the old one. Your config is updated automatically.

FightBot 6.0.18

Released as two builds with the same features: FightBot (6.0.18) for Paper and Purpur, and FightBot for Spigot (6.0.18-spigot) for Spigot and CraftBukkit 26.1+.

Changes

- The join greeting can be turned off. New option messages.greet (default true). Set it to false and nobody is greeted, whoever is listed in messages.greet-players.

FightBot 6.0.17

Released as two builds with the same features: FightBot (6.0.17) for Paper and Purpur, and FightBot for Spigot (6.0.17-spigot) for Spigot and CraftBukkit 26.1+.

New

- `/fb protect` — bodyguards. /fb protect <bot|--all|--group <group>> [player] [behind|front|side] has bots keep close to a player, behind them, in front or down each side, watching the way they look. When anyone hurts that player, every bodyguard goes after the attacker, then returns to its place once the attacker is dead or leaves them alone. Teammates (with groups.friendly-fire off), players in creative or spectator, and a bodyguard's own stray hit never set them off. Settings are in formation.protect.*. - Ready-made loadouts. Five loadouts now come with FightBot, on the bottom row of /fb kits: Diamond Sword, Netherite Sword, Mace, Crystal and Cart. Click one to give it to your bots, or to spawn a new bot wearing it. Nothing to set up first. The commands take their names too: /fb kit Bob mace, /fb save crystal. All armour has Mending and Unbreaking III, and they can't be changed or deleted. - Seven kits and seven saves, up from five each. - A private greeting on join. Players listed in messages.greet-players are told privately, as they join, that the server runs FightBot, with its version, how many bots there are and any update waiting. Nobody else sees it, it gives no permissions and nothing leaves the server. It lists FightBot's author to start with; owners can remove him, add their own staff, or set it to [].

Changes

- Bots no longer fight back against the player they follow. A marching, surrounding or protecting bot that's hit by its own leader takes the hit and stays in line. Anyone else who hits it still gets a fight. formation.ignore-leader: false restores the old behaviour. - Players stay in their groups across restarts. Players added to a group used to be dropped when the server restarted, so a bot could fight back against a teammate afterwards. They now stay in the group until they're taken out.

Tested on

Both builds were tested on a fresh server for every supported version, including a marching bot that doesn't fight its leader and a bot spawned wearing a ready-made loadout: - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

FightBot 6.0.16

Released as two builds with the same features: FightBot (6.0.16) for Paper and Purpur, and FightBot for Spigot (6.0.16-spigot) for Spigot and CraftBukkit 26.1+.

Changes

- `/fb join <number>` is simpler. It now takes just how many bots to send in (1 to 20). Where they join, what they do, and everything else comes from joining.* in the config, so the command and the config never disagree.

Fixes

- Joined bots facing the wrong way. A bot that joined by itself faced whichever way it happened to spawn, so it could walk to its point looking backwards. It now joins facing its point (or the player it's after) and looks the way it's walking.

Tested on

Both builds were tested on a fresh server for every supported version, including a bot joining by itself and walking to its point: - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

FightBot 6.0.15

Released as two builds with the same features: FightBot (6.0.15) for Paper and Purpur, and FightBot for Spigot (6.0.15-spigot) for Spigot and CraftBukkit 26.1+.

New

- Bots that join by themselves. Off by default, so /fb spawn works just as before. Turned on (joining.enabled: true), bots now and then join the server the way players do ("X joined the game"), at the world spawn or a spot you choose, and get on with what they came for: - hunt (the default): go after a player (the nearest, or a random one) and fight them. - point: walk to a point you set. - both: walk to the point, then go after a player. - Hit on the way to the point, a bot fights back and then carries on, ignores it, or runs (joining.when-attacked). - Once done, it wanders about there, logs off like a player, or goes after a player again (joining.afterwards). - How often they join, how many at once, how many players must be online, a group to put them in and a save to join wearing are all in joining.*. - `/fb join [count] [point|hunt|both] [player]` sends bots in now. Name a player and they go after that player. Command blocks can use it too.

Fixes

- Marching and surrounding bots get round things. They go round trees and walls and up and down steps to reach their places, the way they move everywhere else, instead of walking straight at them. A bot stuck behind a tree no longer falls so far behind that it's teleported. - Bots hopping at the foot of a block. An idle, marching or surrounding bot could jump at a one-block step over and over without getting up it. Its jumps now go as high as a player's. - Two marchers wedged in one gap. Two bots squeezing between the same trees could block each other for good. Now the one further back lets the other through first. - Marchers overshooting their places. A bot coming down off a ledge to its place jumped right past it, into the player it was following, and could turn the whole march round. It now steps down. - A place inside a tree. When a bot's place in a formation fell inside a tree trunk, it tried to stand on top of the trunk. It now lines up behind the player instead.

Tested on

Both builds were tested on a fresh server for every supported version, including marching round a wall of logs and up a step, and a bot joining by itself and walking to its point: - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

FightBot 6.0.14

Released as two builds with the same features: FightBot (6.0.14) for Paper and Purpur, and FightBot for Spigot (6.0.14-spigot) for Spigot and CraftBukkit 26.1+.

Changes

- Fewer cobwebs by default. Bots given cobwebs now use them now and then, not at every chance. cobwebs.how-often still turns it up: above 100 a bot doesn't hold on to its webs, and at 200 someone close is webbed within about 2 seconds (the 6.0.13 amount). - Eating works like a player's. Food fills a bot's hunger and the health comes back from that, as yours does. Golden apples give their usual effects (Regeneration, Absorption, and for an enchanted golden apple Resistance and Fire Resistance). Eating used to give health straight away, a whole 16 for an enchanted golden apple. - In a fight a bot eats a golden apple first. Standing about, it eats ordinary food when it's hungry and saves its golden apples. A bot that isn't hungry heals by itself, so it no longer eats apple after apple. - Like a player, a bot that's full can only eat golden apples.

Fixes

- Crystal spam. A bot could place a crystal every tick that it then couldn't set off, dozens at a time, for example when its target had been knocked up above the crystal. Bots now only place crystals they can also hit, and after two in a row that can't be set off they wait a second. - Cobweb in a bot's hand instead of its sword. A bot that showed a cobweb (or a bucket) in its hand and then took out crystals, carts or another item at the same moment could end up holding the cobweb, with its sword put away in its inventory and the crystals lost. Its real item now always comes back first.

Tested on

Both builds were tested on a fresh server for every supported version, including cobweb traps, cart and crystal fights: - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

FightBot 6.0.13

Released as two builds with the same features: FightBot (6.0.13) for Paper and Purpur, and FightBot for Spigot (6.0.13-spigot) for Spigot and CraftBukkit 26.1+.

New: Eyes left and eyes right

/fb march <bot|--all|--group <group>> [player] [left|straight|right] Marching bots can now turn their heads to one side, like a parade's "eyes left", while they keep marching straight on behind you. - `straight` (the default): bots look at the player they're marching behind. - `left` or `right`: bots turn their heads 45° that way and look a little up. - Leave out the player and you lead: /fb march --all left. - The angle and the upward tilt can be changed in the config (formation.march.look-angle, formation.march.look-up).

Better cobwebs

Bots given cobwebs now use them much more, the way good players do: - Feet trap: a cobweb at the feet of someone close. Stuck, they're slow and easy to hit. A bot with someone in reach doesn't hold on to its cobwebs for long. - Head trap: straight after, a cobweb on their head. They can't hit back until they cut it. - Ahead of runners and while healing, as before, now with their own settings. - Cutting itself free: a bot stuck in a cobweb with its target out of reach cuts its way out with a sword or shears. Every part has its own setting, and cobwebs.how-often makes bots use cobwebs more or less overall.

New: Building only with blocks they carry

building.only-own-blocks A player can only pillar with blocks they're carrying, and bots now work the same way. A bot that's been given a kit only pillars, bridges and builds over gaps with blocks from its inventory, and uses them up. With no blocks, it doesn't build. - `kit` (the default): applies once a bot has been given anything. A bot with an empty inventory builds as it always has. - `true`: always. - `false`: never; bots build without carrying blocks.

New: Potion effects in saves and kits

Saves and kits now keep the bot's potion effects, so a bot saved while invisible comes out invisible. Effects keep their level, their time left (or stay forever when given with infinite), and whether their particles show. Bots also keep their effects over a server restart or plugin reload.

Better cart PvP

- Cart PvP up close. Bots used to start a cart only when their target was 3 to 5 blocks away, so someone fighting right next to them never saw one. Now, like a player, a bot cobwebs its target where they stand, steps back and puts the cart in from there. - Any rail works: powered, detector and activator rails as well as plain rails.

Improvements

- `/fb look` works on busy bots. Bots that are roaming, marching or surrounding can now be told to watch someone. A bot that's watching someone keeps watching after being given another order, such as a fight: it looks at its opponent while it fights, then goes back to watching. - Switching formations. Bots already marching or surrounding can be given a new formation, player or direction without being stopped first.

Fixes

- Bots in a formation didn't turn their heads. Marching bots could end up walking backwards, and bots in a ring didn't face the player. Marching bots now look at the player (or left or right), and bots in a ring always look at the player in the middle.

New settings

| Setting | Default | |---|---| | formation.march.look-angle | 45 | | formation.march.look-up | 10 | | cobwebs.how-often | 100 | | cobwebs.cooldown-seconds | 2 | | cobwebs.trap-feet | true | | cobwebs.trap-head | true | | cobwebs.ahead-of-runners | true | | cobwebs.while-healing | true | | cobwebs.cut-own | true | | building.only-own-blocks | kit |

Tested on

Both builds were tested on a fresh server for every supported version, including marching (positions and where bots look), cobweb traps, cart and crystal fights: - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

FightBot 6.0.10

FightBot now comes in two builds, published together on this page with the same features, commands and config: | Build | Version | Runs on | |---|---|---| | FightBot | 6.0.10 | Paper and Purpur, Minecraft 1.20.5 and newer | | FightBot for Spigot | 6.0.10-spigot | Spigot and CraftBukkit, Minecraft 26.1 and newer |

FightBot for Spigot

A new build of FightBot for Spigot and CraftBukkit servers. Bots are real players, exactly as on Paper. They fight, sprint-jump, land critical hits, jump and bridge gaps, wear skins and respond to /fb action. - Requirements: Minecraft 26.1 or newer. Older Spigot versions use scrambled internal names, so bots can't be created there; FightBot says so clearly at startup. - No advancement messages: bots never post "has made the advancement" in chat. - Small differences from Paper: - Knockback taken by bots uses FightBot's own calculation instead of Paper's knockback event. In practice the result is the same. - The "click to copy" button under /fb skins found names isn't shown. - Proxy support (Velocity and BungeeCord) comes from the Paper build. Install that jar on the proxy.

Updates pick the right build

- Paper and Purpur servers only ever download the Paper build. Spigot and CraftBukkit servers only download FightBot for Spigot. - If the wrong build is installed, the right one is downloaded and swapped in at the next restart. - The Paper build won't create bots on Spigot or CraftBukkit. It says at startup to use FightBot for Spigot instead.

Fixes

- Spawning at a location on Minecraft 1.20.5 to 1.21.x: bots now appear exactly where they're spawned, instead of at a random spot near the world spawn. - Bridging wide gaps: on gaps of 5 blocks or more, bots now keep placing blocks until 3 are left, then jump. Previously they sometimes tried a riskier jump-and-place with 4 blocks left and fell.

Tested on

Both builds were tested on a fresh server for every supported version. Each test covered startup, spawning, skins, gap jumps, bridging, holes, chasing, critical hits, /fb action, a full fight, and chat staying free of bot advancement messages. - Paper: 1.20.5, 1.20.6, 1.21, 1.21.1, 1.21.3, 1.21.4, 1.21.5, 1.21.6, 1.21.7, 1.21.8, 1.21.9, 1.21.10, 1.21.11, 26.1.1, 26.1.2, 26.2, 26.3 - Spigot: 26.1.2, 26.2, 26.3

Upgrading

FightBot updates itself. The new version downloads automatically and is installed the next time the server restarts. If you've turned automatic downloads off (updates.download: false), download the new jar and replace the old one. Your config is updated automatically.

FightBot 6.0.7

Manual movement

/fb action can now move a bot by hand. Movement works like holding down a key: the bot keeps moving until it is told to stop, or for a set number of seconds. | Command | What it does | |---|---| | /fb action <bot> walk [forward\|back\|left\|right] [seconds] | Walks in that direction, relative to where the bot is facing. Defaults to forward. | | /fb action <bot> sprint [seconds] | Sprints forward. Sprinting only works forward, as for a player; other directions walk. | | /fb action <bot> stop | Stops walking or sprinting. | | /fb action <bot> turn <left\|right\|around\|degrees> | Turns the bot. Positive degrees turn right. | - Nothing is automatic. A bot moving by hand does not step up blocks, stop at edges or path around obstacles. It bumps into walls and walks off ledges like a player would. Use /fb action <bot> jump to jump while it moves, including sprint-jumps. - Speeds match a player's: walking about 4.3 blocks a second, sprinting about 5.6, and crouch-walking about 1.3 when the bot is crouched (/fb action <bot> crouch). - Works with --all and --group <group>, and tab completion suggests directions and turn options. - /fb stop also ends manual movement.

FightBot 6.0.6

Movement

- Single missing blocks are walked around. A one-block hole in otherwise solid ground is now stepped around, as a player would, instead of being jumped. Trenches and gaps that span the path are still jumped. - Gaps too wide to jump. While chasing a target (or following a route that allows building), bots now handle gaps of 4 to 12 blocks: - 4-block gaps: the bot sprint-jumps and places a block at the far end mid-jump to land on. Like a player, it occasionally misses the placement. - 5 to 12 blocks: the bot bridges out one block at a time until 3 blocks are left, then jumps the rest. - Bots roaming without a target never place blocks over gaps.

New settings

| Setting | Default | |---|---| | movement.gap-blocks | true |

Upgrading

Replace the jar and restart. The new setting is added to your existing config.yml automatically.

FightBot 6.0.5

Movement

- Sprint-jumping. Bots chasing a player across open ground now sprint-jump, as players do. This is faster than running: in testing, a bot chasing a sprinting player went from 5.5 to 6.4 blocks per second and closed a 14-block lead. - Critical hits from a run-up. A sprint-jump that brings a bot down on its target lands as a critical hit. The bot stops sprinting just before the hit, as the game requires. - Jumping gaps. Gaps up to 3 blocks wide are jumped across instead of being walked around, waited at, or bridged. This includes ditches, single missing blocks, and gaps on hillsides where the far side is one block higher or lower. Route planning also considers jumps, so a bot can go around a wall and then jump a gap. - Bots do not jump gaps that are too wide to clear, and they do not jump when their target is down in the gap.

New settings

| Setting | Default | |---|---| | movement.sprint-jump | true | | movement.jump-gaps | true |

Upgrading

Replace the jar and restart. The new settings are added to your existing config.yml automatically.

FightBot 6.0.4

New

- `combat.one-hit-players`: a list of player names that every bot knocks out in a single hit, whatever weapon it is using (melee, arrows or a mace). Useful as a challenge mode for players who find the bots too easy. Names are not case sensitive, and the list is empty by default. - A shield that blocks the hit still blocks it, and a Totem of Undying still saves the player once.

Upgrading

Restart your server. The new setting is added to your existing config.yml automatically.

FightBot 6.0.3

Faster bots. Bots now cost the server a lot less, and they fight exactly the same. Updating from 6.0.x? Just swap the jar. Nothing to set up.

Performance

- With 40 bots fighting on our test server, the server's tick time dropped from about 22–26 ms to 14 ms (out of the 50 ms a tick can take). That's about 40% less, so there's more room for players, or for more bots. - What changed: FightBot used to look up the game's own methods (for turning a bot's head, moving it, jumping and attacking) all over again every tick, for every bot. Now it looks each one up once and keeps it. Turning the head was the worst: it cost more than everything else a fighting bot does put together. - Bots standing around were already cheap. Their checks for someone coming at them cost almost nothing, so they still react the moment something happens. -

FightBot 6.0.2

Bots that live to fight back, elytra bots that land where the fight was, and a new /fb action command. Updating from 6.0.x? Just swap the jar. Your config keeps every setting, and new ones are added with their defaults.

Caught off guard (new)

A bot that isn't fighting anyone can't lose more than half its health to the hit that starts a fight, a mace smash from the sky included. So it lives to fight back. Every hit after that is normal. - combat.first-hit-cap: 50 is the % of its health that first hit may take (1 to 100). 100 turns it off. - It counts as "caught off guard" when it isn't fighting anyone and hasn't been hit for 15 seconds.

Elytra

- Fixed: a bot that won a fight in the air (or was told to stop) just glided off the way it was facing, and sometimes got stuck. Now it glides back down to where the fight was, circles down round the spot, and lands there with its chestplate back on. - Stuck against a tree or a wall mid-glide, it drops out of the glide and lands.

/fb action (new)

`/fb action <bot|--all|--group <group>> <action>` makes a bot do one thing a player does with their keys and mouse: - `jump` - `crouch`: the same again to stand up. - `left-click`: a swing, hitting whatever it's looking at in reach. - `right-click`: the block it's looking at (a door, button, lever or chest), or else the item in its hand (a pearl or snowball thrown, food eaten, a bow drawn and shot, a shield raised). Use /fb look <bot> <player> first to turn it toward someone.
