RGB split effect
Separate each component's RGB(red, green, blue) colors and display them on the screen with an offset:

Each color channel has its own X and Y offset, so you can control the direction and strength of the separation for the red, green and blue channels independently. Small offsets give a subtle chromatic aberration around edges, while larger ones create a strong glitch or "damaged screen" look. Animate the offsets with events to make the distortion pulse (for example when the player takes damage).
