Speedlines : Manga Style !

Based on the excellent work of Exuin

Add to your shader material a NoiseTexture2D then a FastNoiseLite with the following parameters to obtain the same effect:

• Enable Seamless
• Noise Type : Simplex
  • Frequency: 0.09

Enjoy 😉 

Shader code

shader_type canvas_item;

uniform sampler2D noise : repeat_enable;
uniform vec4 line_color_a: source_color = vec4(2.0, 0.0, 0.0, 1.0);
uniform vec4 line_color_b: source_color = vec4(1.0, 1.0, 0.0, 1.0);
uniform vec4 back_color: source_color = vec4(0.271,0,0,1);
uniform float line_threshold: hint_range(0.0, 1.0, 0.01) = 0.8;
uniform float speed: hint_range(0.0, 1.0, 0.01) = 0.03;
uniform float line_length = 1000.0;
uniform float angle: hint_range(0.0, 360.0) = 60.0;


void fragment() {
	vec2 uv = vec2(UV.x * cos(radians(angle)) - UV.y * sin(radians(angle)), UV.x * sin(radians(angle)) + UV.y * cos(radians(angle)));
	vec4 noise_line = texture(noise, vec2(uv.x / line_length + fract(TIME) * speed, uv.y));
	vec4 color;
	if (noise_line.r < line_threshold){
		color = back_color;
	} else {
		color = mix(line_color_a, line_color_b, 1.0 - noise_line.r);
	}
	COLOR = color;
}
