Update 1.1.3

• Added a feature to cancel shooting

• Fixed an issue where the number of arrows on the character’s back did not match the actual arrow count

• Fixed an issue where an arrow would be fired if the bow was unequipped while drawing

• Fixed Control Rig mismatches across different bow and arrow models

• Fixed issues caused by unequipping during rapid-fire mode

• Fixed an issue where arrows would be reclaimed while in the drawing state when UseBowAnimation = False

Update 1.1.2

• Added the ability to switch bow types at runtime

• Added the Uninitialize function

Update 1.1.1 ：

• Fixed the arrow’s position jitter issue when quickly drawing and releasing the bow.

• Removed the dependency on Character and established dependencies by registering the Mesh.

• Modified the bow model to make the top and bottom ends of the bow more distinguishable.

• Fixed an issue where, when drawing the bow to its limit, the release animation sometimes played but the arrow was not shot.

• Fixed the position offset issue when aiming for the first time.

Ultimate Bow System is a fully featured and highly customizable bow-and-arrow combat framework. It covers everything from character animations, bow animations, charging, predictive shooting, quick shots, procedural controls, to partial network replication.

The system includes Bow Control Rig, allowing you to freely choose between procedural bow animation or a fully authored bow animation set.

✨ Key Features

🎬 20 Bow & Character Animations Included

Covers the full workflow: Aim, Idle, Charge, Shoot, Equip, Unequip.

🏹 Procedural Bow Animation & Custom Bow Animation

Choose between:

Procedural Bow Animation

• Automatic bow bending

• Automatic string pull

• Auto-adjusted arrow direction

Custom Bow Animation

⚡ Complete Shooting Pipeline

• Charging with maximum charge limit

• Minimum charge threshold

• Quick shot (fire immediately on click)

• Charge cancel

• Arrow-depleted state transition

• Shooting cooldown management

🧰 Fully Data-Driven System

Configure everything through BP_BowDataAsset:

• Models (bow, arrow, quiver)

• Animations (bow animations, character animations)

• Socket names (hand, back, quiver, etc.)

• Bowstring force, max stretch length, bow bending curve

• Prediction line effects

• Arrow class, speed, gravity, launch parameters

📈 Predictive Shooting

• Predicts trajectory based on camera center

• Procedurally determines arrow launch direction

• Optional prediction line (Niagara/VFX supported)

🎯 Procedural AimOffset

Automatically rotates the character’s upper body toward the aim direction, fully compatible with UE’s default humanoid skeleton.

👥 Replication(Experimental)

• Basic replication included; network-focused projects may require additional logic

• Dedicated Server setups require adjusting SkeletalMesh Tick settings (explained in the documentation)
