Simple Worldborder
A simple Minecraft style animated worldborder.
I am no shader expert, so please comment if there is something to improve.
Shader code
shader_type spatial;
render_mode shadows_disabled;
uniform float scale = 5.0;
uniform vec4 color : source_color = vec4(0.225, 0.97, 0.9, 0.25);
void fragment() {
vec2 uv = UV * scale;
float ar = (VIEWPORT_SIZE.x/VIEWPORT_SIZE.y);
float t = (fract(TIME/7.5) * scale);
float x = uv.x + (uv.y * ar) - t;
ALPHA = 0.0;
for(float i = -4.0; i < 4.0; i += 0.25) {
float off = (i * scale) + x;
if(off > 0.0 && off < 0.5) {
ALBEDO = vec3(color.rgb) * mix(0.25, 1.0, off);
ALPHA = color.a;
}
}
}
