bow
boostin

automates the bow boost movement technique. hold a bow, press a key, and the mod handles the jump timing, camera rotation, draw, and release for you.

installation

client-side only - no server install needed. works on any server you can join normally.
01

install fabric

grab the fabric installer from fabricmc.net and run it for minecraft 1.21.11.

02

add fabric api

download fabric api from modrinth and put the jar in your mods folder.

03

add bow boostin

put the bow boostin jar in the same mods folder.

04

launch

start minecraft with the fabric profile. ⚡ bow boostin ready! in the log means it worked.

// 03

how it works

when you press the boost key, this sequence runs:

01

checks

verifies you're on the ground, holding a bow (either hand), and have arrows. fails with a message if not.

02

sprint + jump

forces a sprint and triggers a jump. you don't need to be sprinting beforehand.

03

wait for apex

waits until upward velocity hits near zero - the top of the jump. 15 tick timeout if something goes wrong.

04

aim up

rotates your camera to the configured angle (default 78°). snap or smooth depending on your setting.

05

draw + release

holds the bow for your draw ticks then releases. arrow goes up, arcs back down, knockback sends you forward.

06

restore + cooldown

camera goes back to where it was. cooldown ticks out, then you can boost again.

keybind

B
bow boost
settings -> controls -> bow boostin

rebind in controls, or use /bboost keybind <key> in-game. pass a plain key like r or mouse.left — no need for the full internal name.

// 05

commands

all client-side. no server perms needed. tab complete works on everything.

/bboost show help
/bboost toggle enable / disable

turns the mod on or off. when off, the boost key does nothing. faster than messing with keybinds.

/bboost mode toggle | hold activation mode

toggle - one press, one boost, re-press for another.
hold - same for now, reserved for future use.

/bboost delay 0-200 ticks cooldown

wait time between boosts. default 0. 20 ticks = 1 second. useful if you keep double-triggering.

/bboost angle 10-89 degrees look-up angle

how far up the camera rotates before firing. default 78°. affects horizontal distance - play around with it.

/bboost draw 1-20 ticks bow draw time

how long the bow is held before releasing. default 3 ticks (150ms). don't go too high - you want a weak shot that arcs back fast, not one that flies off into the distance.

/bboost movement snap | smooth camera style

snap - instant rotation, most reliable.
smooth - ease-out over 4 ticks, looks nicer but slightly slower.

/bboost keybind <key> change boost key

change your key without opening settings. examples: r, g, mouse.left. the mod handles the full internal key name.

/bboost status show current config

prints all your current settings to chat at once.

settings don't save between sessions. re-apply after restarting.

tips

#
60° to 78° is the sweet spot. too high = and the arrow takes ages to come back. too low = the knockback is weak.
#
bow works in either hand. offhand is handy so you can keep a tool or weapon in your main hand.
#
keep draw at 3 to 5 ticks. you want an undercharged shot. a full charge will just send the arrow flying off and it won't come back.
#
snap is faster than smooth. smooth adds 4 ticks to the sequence. use it for recordings or to look legit, stick with snap otherwise.
#
opening any ui mid-boost (inventory, chat, esc) aborts the sequence and restores your camera.
#
anti-cheat warning. some servers may flag the camera rotation or simulated inputs. be careful on some servers.

notes

purely client-side. no server install, no op permissions needed for any commands.
regular, tipped, and spectral arrows all work. every inventory slot is checked.
the arrow is a real projectile - uses one arrow per boost and can hit players or mobs on the way down.
