Better ballista AI, Finnish shot

🏹 ReBallista

Mod Version Game Version Platform Translations Ko-fi

ReBallista completely overhauls the vanilla ballista AI into a lethal, reliable base defense system! No more getting shot in the back by your own ballistas or watching precious bolts fly harmlessly over crawling enemies.

By default, ballistas now strictly protect you and your pets, track targets smoothly, lead their shots based on enemy movement, and fire laser-focused bolts with subtle mid-flight homing.


🎮 Features at a Glance

| Feature | Description | | :--- | :--- | | 🛡️ Zero Friendly Fire | Ballistas will never target players or tamed animals (wolves, loxes, boars, etc.). | | 🎯 Predictive Aiming | Automatically calculates projectile velocity and distance to lead moving targets with precision. | | 🏹 Smart Homing Bolts | Fired bolts dynamically adjust their trajectory mid-air (up to 65°/s) to guarantee direct hits. | | 📐 Low-Profile Targeting | Automatically adjusts vertical aim for short or crawling enemies (Ticks, Necks, Leeches) so bolts don't fly overhead. | | ⚡ Pinpoint Accuracy | Removes random vanilla projectile inaccuracy for dead-on precision. |


✨ How It Works (Made Simple)

  • A Real Friend, Not a Hazard: Vanilla ballistas are notorious for friendly fire. ReBallista completely disables player and tamed creature targeting by default. Build perimeter defenses without fear.
  • Smart Motion Lead: Instead of shooting directly at where a target used to be, the turret reads the enemy's velocity vector and leads the shot according to distance and ammo flight time.
  • Mid-Air Micro-Guidance: Even erratic or suddenly turning enemies can't escape: bolts apply a smooth homing adjustment in flight when closing in within 25 meters.
  • Fixing the Short Target Bug: Vanilla ballistas constantly overshoot short hitboxes. ReBallista dynamically measures target height and lowers the aimpoint for low-slung enemies.
  • Silky Smooth Tracking: Turret rotation and acceleration have been completely reworked, giving the ballista a responsive, high-speed traverse while sweeping and aiming.

📥 Installation

Using a Mod Manager (Recommended)

  1. Install r2modman or Thunderstore Mod Manager.
  2. Search for ReBallista by Skarif.
  3. Click Download with Dependencies and launch the game!

Manual Install

  1. Make sure you have BepInExPack Valheim installed.
  2. Download the mod archive and drop ReBallista.dll into:

Valheim/BepInEx/plugins/.

  1. Launch the game and enjoy your deadly automated defenses!

Configuration

After the first launch, edit BepInEx/config/com.skarif.reballista.cfg and restart the game.

| Setting | Default | Description | | :--- | :--- | :--- | | EnableFriendlyFire | false | Set to true to allow ordinary and custom ballistas to target players and tamed creatures, including with trophy filters. Improved aiming and homing remain enabled. | | EnableAshlandsBallistas | false | Apply improved behavior to hostile Ashlands bone ballistas (Skugg). These remain hostile regardless of EnableFriendlyFire. | | MaxAmmo | 0 | Maximum loaded bolts for finite-ammo ballistas (1–10000). 0 preserves original capacity. Unlimited-ammo turrets remain unlimited. Existing loaded bolts are preserved. | | BallistaRange | 0 | Target acquisition range in meters (0–1000). 0 preserves each ballista's vanilla range. |

Friendly-target protection controls target selection; it does not prevent damage from stray bolts. For custom structures intended to attack the player, use EnableFriendlyFire = true.

ReBallista — полная переработка искусственного интеллекта баллисты, превращающая её в надёжного и смертоносного защитника вашей базы! Забудьте о временах, когда турель расстреливала вас в спину, а болты бессмысленно летели над головами ползающих врагов.

По умолчанию баллиста безошибочно различает своих, плавно ведёт цель, стреляет на упреждение и выпускает сверхточные болты с умной доводкой прямо в полёте.
