Agentic FeedbackFX (ScreenFX, HitStop, Impact Frames, Haptics, Shakes) – C++ – Unreal Engine
The difference between “I pressed a button” and “I FELT that.”
That’s game feel. ScreenFx, hit stop, camera shake, impact frames, the rumble in your hands. The stuff that makes combat satisfying – and the blood vignette when you’re low on health, the fire overlay when you’re burning, the screen pulse when poison ticks.
Note: Includes 1 sample post-process material. This plugin is the system – pair it with your own materials or asset packs for the full effect (more below)
C++ Native | Multiplayer-Safe | Data Asset Config
Modular Event-Driven Architecture
Create custom events. Create custom triggers. Everything lives in one Data Asset config – not scattered across your codebase.
– Custom Events – Subclass `UAgenticFeedbackFXEvent` for new screen effects
– Custom Triggers – Subclass `UAgenticFeedbackFXTrigger` for new automation
The 6 events and 2 triggers are starting points. Extend the system without touching existing code.
The 6 Built-In Event Types
– Camera Shake – Magnitude-scaled shakes with curve support and coordinate space options
– Hit Stop – Time dilation with 6 recovery curves, multiplayer ready
– Post Process (Temp) – Blood splatter, screen flash, damage vignette with auto-fade. Pass custom params to materials.
– Post Process (Persistent) – Low health vignette, status effects that stay until removed
– Impact Frame – Screen flash or Niagara VFX at impact location. Pass custom params to Niagara systems.
– Audio – 2D/3D sounds with magnitude-scaled volume and pitch variation
– Haptics – Controller rumble with large/small motor control and force feedback support
Automatic GAS Triggers
Two trigger types built-in:
– Attribute Threshold – Health drops below 25%? Vignette appears. Recovers above 30%? Fades. Hysteresis prevents flickering.
– Status Effect – Got a Burning tag? Fire screen effect. Rooted? Dust vignette. Tag removed? Effect clears automatically.
– Create via Blueprints – Easily bind to any events via blueprints
Zero code in your damage or status systems. Configure in Data Assets.
