Retro Screen Lines
uhm. idk how to describe this one.
anyways uhm lets go look to the params,
lineCount is how many black lines there should be.
timeSpeed is how fast it moves.
and darknessMult is how visible the lines are.
Shader code
shader_type canvas_item;
uniform int lineCount : hint_range(2, 9000) = 70;
uniform float darknessMult : hint_range(0.0, 1.0) = 0.25;
uniform float timeSpeed : hint_range(1.0, 65.0) = 6.5;
void fragment() {
float wave = cos(UV.y*PI*float(lineCount)+(TIME*timeSpeed));
float slowwave = cos(UV.y*PI*float(lineCount/50)+(TIME*timeSpeed/2.5));
float square = round(wave);
vec4 retroLines = vec4(
square,
square,
square,
((-square)*darknessMult)
);
vec4 darkwaves = vec4(0.0,0.0,0.0,((-slowwave)*darknessMult/2.0));
COLOR = (darkwaves + retroLines) / 5.0;
}
