Update 2026/01/20: The UltimateHitreactionPlugin no longer needs to be obtained after verification on Discord; instead, it is provided as an additional file.
Update 1.4:
- Added IK-based hit reaction feedback.
- Enter the ragdoll state upon death.
Update 1.3: Fix Light_Back_Chest and Light_Front_Chest, modify the light/heavy stacking implementation in the hit reaction system, and fix the top explosion issue.
Ultimate Hit Reaction System is a powerful hit reaction framework designed for humanoid characters in Unreal Engine. It allows for rapid integration and brings high-quality, dynamic response animations to your game characters and NPCs. With a rich animation library and data-driven architecture, your combat feedback will become more vivid and responsive.
🔧 Key Features
- ⚡ Rapid Integration: Integrate within 30 minutes (basic knowledge of animation systems recommended). Setup is fully Blueprint + Chooser DataTable, no coding required.
- 🎥 Extensive Animation Library: Includes 168 motion-captured animations covering:
- 🎯 Directions: Front / Back / Left / Right / Up / Down
- 🔺 Strength Levels: Light / Medium / Heavy / Explosion
- Includes partial hits, knockdowns, falls, launch reactions, combo impacts, and more.
- 🧠 Smart Animation Switching: Automatically selects appropriate animations based on hit direction and intensity—no manual setup needed.
- 🔁 Broad Compatibility: Built for humanoid characters and creatures. Compatible with diverse skeletal meshes and ideal for player characters, NPCs, and Bosses.
- 📊 Data-Driven Architecture: Behaviors are defined through Chooser Tables for easy tuning, expansion, and full multiplayer replication.
- 🧪 Physics Control(Experimental): Optional Physics Control module adds physical interaction to animations (experimental and toggleable).
- 🌀 Motion Warping Support: Fully supports UE’s Motion Warping system to dynamically adjust hit direction and landing position—making reactions like knockbacks and falls more fluid and accurate.
- 💀 Integrated Death Animations: Includes multiple death scenarios (e.g., instant collapse, knockback-to-death), seamlessly connected with the hit system for unified logic.
⚠️ This product includes the full animation set—no need to purchase additional animation packs separately.
