Gameplay-Driven Controls

HorrorScreenFX can be controlled directly from gameplay scripts.

Use the included runtime properties to connect the screen effects to player health, fear, sanity, danger, paranormal activity or environmental events.

Example:

HorrorScreenFX.set_fear(0.75)
HorrorScreenFX.set_insanity(0.50)
HorrorScreenFX.set_signal_loss(0.80)
HorrorScreenFX.trigger_damage()

Values can be changed gradually during gameplay to create progressive visual reactions.

Fear and Insanity Effects

Connect HorrorScreenFX to your own fear or sanity system to increase screen instability as the player becomes more vulnerable.

These controls can be used for:

• progressive psychological distortion;
• enemy proximity feedback;
• haunted locations;
• low-sanity gameplay;
• nightmare sequences;
• paranormal events.

---

Damage Feedback

Trigger immediate screen reactions when the player takes damage.

Damage feedback can combine flashes, distortion, blur, vignette and color changes to reinforce the impact without requiring a separate visual system.

HorrorScreenFX.trigger_damage()

---

Signal Loss and Blackout

Create unstable cameras, damaged video feeds, paranormal interruptions or complete signal failures.

Signal loss and blackout controls can be used for:

• security camera systems;
• found-footage sequences;
• television and monitor effects;
• paranormal encounters;
• scene transitions;
• temporary visual interruptions.

---

Global Intensity Control

Adjust the overall intensity of HorrorScreenFX without modifying every individual effect.

HorrorScreenFX.set_global_intensity(0.75)

This makes it possible to reuse the same preset with different strength levels depending on the gameplay situation.

---

Customizable Effects

Each screen effect can be configured independently.

You can:

• enable or disable individual effects;
• adjust effect intensity;
• modify visual parameters;
• combine several effects;
• create your own horror style;
• use the included presets as starting points.
