Advanced Physics Based Bullet Projectile System for Unreal Engine
The Bullet Projectile System is a high-performance, physics-driven bullet simulation framework designed for Unreal Engine. It provides realistic projectile behavior, including gravity effects, drag force, wind influence, penetration, and ricochet mechanicsโall optimized within a World Subsystem for seamless performance.

Key Features
โ Physics-Based Projectile Simulation
Fully customizable bullet speed, mass, cross-section, and drag coefficient.
Real-time gravity, wind resistance, and environmental influences.
Use Gameplay Cue Notify (Burst) for advanced effects (Decal, Niagara, Sound, Camera shake)
โ Penetration & Ricochet System
Advanced penetration logic based on material properties.
Dynamic ricochet calculations depending on impact angle and velocity.
โ Wind Influence
Integrates with UWindDirectionalSourceComponent for realistic wind effects.
Automatically adjusts bullet trajectory based on wind strength and direction.
โ Impact & Visual Effects
Customizable decals and particles for bullet impacts and ricochets.
Debug visualization for projectile paths, impacts, and penetration results.
โ Optimized & Scalable
Uses TInlineAllocator<40> for efficient projectile management.
Subsystem-based design eliminates performance overhead from actors.
โ Easy Integration & Customization
Fire projectiles using simple function calls (FireProjectile(), FireProjectiles()).
Configure bullet physics via data assets (ProjectileData, PhysMaterialDataAsset).
Fully supports Blueprint and C++ workflows.
Ideal For
Realistic shooting mechanics in FPS/TPS games.
Ballistic simulation for military or training applications.
Physics-based projectiles in survival, battle royale, or open-world games.
๐ก Compatible with Unreal Engine 5+ | Works with Niagara VFX & Gameplay Ability System (GAS).
