Bow Boostin'

> Description:

Bow Boostin is a client-side Fabric mod for Minecraft 1.21.11 that automates the bow boost movement technique - that thing where you sprint, jump, quick-draw a bow straight up, and the arrow comes back down and knocks you forward. It's a legitimately fast way to travel, but pulling it off manually is awkward and timing-dependent. This mod handles the whole sequence for you with a single keypress.

How It Works

When you trigger a boost, the mod runs through a tightly sequenced state machine:

1. Saves your current camera angle
2. Makes sure you're sprinting
3. Jumps
4. Waits until you're at the peak of the jump (when your upward velocity drops to near zero)
5. Snaps or smoothly rotates your camera up to your configured angle (default 78°)
6. Holds the bow draw for a configurable number of ticks
7. Releases, firing the arrow upward
8. Restores your camera to where it was
9. Enters a cooldown period before allowing another boost

Before any of this happens, the mod checks that you're actually holding a bow, that you have arrows, and that you're on the ground. If any of those conditions aren't met, you'll get a quick error message and nothing happens.

Requirements

• Minecraft 1.21.11
• Fabric Loader 0.19.2 or newer
• Fabric API
• Java 21+

---

Keybind

The boost is bound to B by default. It shows up in your keybind settings under the Bow Boostin category. You can rebind it there, or use the /bboost keybind command described below.

---

Commands

Everything is configured through the /bboost command. Tab completion works on all arguments.

---

/bboost

Shows the full help menu with a list of every available subcommand and what it does.

---

/bboost toggle

Enables or disables the mod entirely. When disabled, pressing the boost key does nothing. Useful if you want to quickly turn it off without uninstalling or changing your keybind.

---

/bboost mode <toggle|hold>

Controls how the keybind behaves.

• toggle - Press the key once to trigger one boost. You have to release and press again for another. This is the default.
• hold - Functionally the same right now; one press fires one boost and you need to re-press. The distinction is there for future development.

---

/bboost delay

Sets a cooldown between boosts, measured in ticks (20 ticks = 1 second). Accepts values from 0 to 200. Default is 0, meaning you can chain boosts as fast as the sequence completes. Setting a delay gives you more control if you find yourself accidentally triggering back-to-back boosts.

---

/bboost angle

Sets the angle in degrees that the mod rotates your camera upward before firing. Accepts values from 10 to 89. Default is 78°. Higher angles send the arrow more directly overhead, which is generally what you want for maximum knockback distance. You might want to experiment with this depending on your situation.

---

/bboost draw

Sets how many ticks the bow is held drawn before releasing. Accepts 1 to 20. Default is 3 ticks (150ms). A longer draw charges the bow more, which affects arrow velocity and ultimately how much knockback you get. At 3 ticks the bow isn't anywhere near fully charged — the goal is a low-velocity arrow that arcs back down quickly, not a fully powered shot that flies off into the distance.

---

/bboost movement <snap|smooth>

Controls how the camera moves during the boost sequence.

• snap - Your camera instantly jumps to the target angle and back. This is the default, and it's the most reliable.
• smooth - The camera interpolates to the target angle and back over 4 ticks using an ease-out curve. It looks nicer but adds a few ticks to the sequence.

---

/bboost keybind

Changes the boost key without going into the keybind settings menu. You can pass a key name like r, g, mouse.left, etc. The mod will figure out the correct internal key name — you don't need to type key.keyboard.r, just r is fine. Mouse buttons use the format mouse.left, mouse.right, etc.

---

/bboost status

Prints your current configuration to chat. Shows whether the mod is enabled, your current keybind, mode, camera movement style, angle, draw time, and cooldown.

---

Notes

• The boost aborts automatically if you open any screen (inventory, chat, etc.) mid-sequence and tries to restore your camera angle cleanly.
• The mod works with arrows in any inventory slot, including spectral and tipped arrows.
• The bow can be in either your main hand or your offhand.
• Settings are not currently saved between sessions — you'll need to re-apply any changes after restarting.
