Compound Bow V1.07 - Projectile Overhaul

📝 Compound Bow Datapack — Projectile Overhaul (v1.7)

This update is the biggest leap forward since the initial release. The Compound Bow system has been completely re-engineered for performance, accuracy, and compatibility across all mobs and bosses — including the Ender Dragon.

⚔️ Combat Engine Redesign

• ✅ Replaced /damage command’s arrow type with mob_attack to bypass Enderman and Ender Dragon immunities.

• ✅ Damage now applies XP, loot, and kill credit properly with full player attribution.

• ✅ Special-case functions like damage_ender_dragon.mcfunction are now obsolete.

🎯 Projectile System Streamlining

• ❌ Removed intermediary armor_stand entirely.

• ✅ interaction entity now serves as the sole projectile (ray_arrow), dramatically reducing entity count and tick overhead.

• ✅ Hit detection is now volume-based, leveraging real interaction entity dimensions instead of simulated raycast offsets.

🔢 Shooter Tracking with Virtual UUID

• ✅ Introduced Player_ID system to virtually emulate UUIDs without needing data modify or NBT.

• ✅ Each arrow stores its shooter’s Player_ID, and matches it back on hit to tag the real shooter.

• ✅ Fully scoreboard-driven — no NBT UUID hacks required.

🔁 Damage Pipeline Unification

• ✅ damage_by_table.mcfunction now supports ShotPower-scaled damage with:

  • Clean /damage calls per tier (9–54)

  • Shooter tagged by Player_ID

  • No special-case logic per entity

• ✅ Endermen, Dragons, and all mobs now take damage from the same system.

🧼 System Hygiene & Cleanup

• ✅ damage_precalc, Player_ID, ShotPower, and ray_step are all reset immediately after use.

• ✅ Shooter tags are removed after damage is applied.

• ✅ This ensures zero scoreboard or tag clutter, even in multiplayer.

🧱 Environment Interaction Improvements

• ✅ Iron bars are now included in not_solid.json, allowing arrows to snipe End Crystals behind cages — no TNT or block breaking required.

🔧 Performance & Compatibility

• ✅ Optimized for multiplayer — unique Player_ID per player prevents attribution bugs.

• ✅ No reliance on UUID, NBT storage, or storage data.

• ✅ Compatible with bosses, vanilla progression, and custom advancement triggers.
