Noise Laser

Simple shader that shows a laser around a line based on a noise.

The line shoud be at the center of the sprite, vertically (rotate the whole sprite if needed).

See the gif posted above to have an idea of it running…

Shader code

shader_type canvas_item;

uniform float strength = 4.0;
uniform sampler2D noise;

void fragment() {
	COLOR = texture(TEXTURE,UV);
	float noise_value = texture( noise, vec2(fract(TIME), UV.y) ).r;
	if (COLOR.a == 0.0) {
		float dist_to_mid = abs(UV.x - 0.5) * 2.0;
		COLOR = vec4(1.0, 1.0, 1.0, strength * noise_value * (1.0 - dist_to_mid) * (1.0 - dist_to_mid) );
	}
}
