2D Shine Highlight

Found on reddit, thought I’d share it here too. Has 3 params:

  • shine_color: A color (can be transparent!)
  • shine_speed: How quickly it passes
  • shine_size: how wide it is
Shader code
shader_type canvas_item;

uniform vec4 shine_color : hint_color = vec4(1.0);
uniform float shine_speed : hint_range(0.0, 10.0, 0.1) = 1.0;
uniform float shine_size : hint_range(0.01, 1.0, 0.01) = 0.01;

void fragment() {
	COLOR = texture(TEXTURE, UV);
	float shine = step(1.0 - shine_size * 0.5, 0.5 + 0.5 * sin(UV.x - UV.y + TIME * shine_speed));
	COLOR.rgb = mix(COLOR.rgb, shine_color.rgb, shine * shine_color.a);
}

Hey all, I just put out an “improved” version of this shader here that allows you to adjust the progress and angle of the shine animation.
