Analytical Die / Dice Texture
No textures! Only boolean math goodness!
I challenge you to do this in less lines (of reasonable length of course)
Shader code
shader_type canvas_item;
uniform int value: hint_range(1, 6, 1) = 1;
void fragment() {
vec2 uv = UV * 3.0;
float d = distance(ceil(uv) - 0.5, uv) - 0.45;
float m = smoothstep(fwidth(d), 0.0, d);
int c = abs(int(floor(uv.y) * 3.0 + floor(uv.x)) - 4);
m *= float(c != 3);
m *= float(c != 2 || value >= 2);
m *= float(c != 4 || value >= 4);
m *= float(c != 1 || value >= 6);
m *= float(c != 0 || value % 2 == 1);
COLOR.rgb = vec3(1.0 - m);
}
