This shader is the solution for developers looking to add digital corruption, horror elements, or sci-fi UI effects to their projects. Unlike static overlays, this shader generates procedural noise-based distortion in real-time, including a high-quality RGB channel split.

Perfectly optimized for performance, ensuring smooth transitions even on mid-range laptops and integrated graphics.

Key Features

• ✅ Procedural Animation: Dynamic seed generation for ever-changing glitch patterns.
• ✅ Integrated RGB Split: Chromatic aberration built directly into the displacement logic.
• ✅ Density Control: Switch between full-width horizontal shifts and fragmented "broken" blocks.
• ✅ Smart Padding: Includes mesh_pad logic to prevent visual clipping during extreme distortion.

Installation & Usage

1. Easy. Download glitch_shader.rpy and drop it into your /game folder.

2. Call the shader in your script using Beginner Presets or Custom Parameters:

# --- USE A PRESET ---
show character at intense_broken_glitch
show character at subtle_glitch
# --- CUSTOM CONFIGURATION ---
show character at glitch(strength=5.0, density=20.0)

Available Presets

Preset Name	Effect Description
glitch_static_preset	Fixed distortion pattern (non-animated).
subtle_glitch	Very light horizontal line shifts.
normal_glitch	Standard animated line distortion.
intense_glitch	Heavy displacement with RGB splitting.
extreme_glitch	Violent horizontal shaking and artifacts.
subtle_broken_glitch	Small, high-density fragmented shifts.
normal_broken_glitch	Noticeable fragmented "digital noise" look.
intense_broken_glitch	Strong block-based corruption.
extreme_broken_glitch	Severe screen fragmentation.
crashed_glitch	Total system instability / Crash effect.
