TopDown Game 2D Cloud shader
I use this shader with a
– ParallaxBackground
-ParallaxLayer
-ColorRect
Set the mirroring on your ParallaxLayer to your window resolution
Shader code
shader_type canvas_item;
//render_mode unshaded; // optional
// Noise texture
uniform sampler2D noise_texture: repeat_enable, filter_nearest;
// Fog density
uniform float density: hint_range(0.0, 1.0) = 0.25;
// Fog speed
uniform vec2 speed = vec2(0.02, 0.01);
// Called for every pixel the material is visible on
void fragment() {
// Make the fog slowly move
vec2 uv = UV + speed * TIME;
// Sample the noise texture
float noise = texture(noise_texture, uv).r;
// Convert the noise from the (0.0, 1.0) range to the (-1.0, 1.0) range
// and clamp it between 0.0 and 1.0 again
float fog = clamp(noise * 2.0 - 1.0, 0.0, 1.0);
// Apply the fog effect
COLOR.a *= fog * density;
}
