Topdown windy plants
Topdown windy plants shader
Then used OpenSimplexNoise to provide the wind to the plants
Shader code
shader_type canvas_item;
render_mode blend_mix;
// Wind settings.
uniform vec2 wind = vec2(0, 0);
uniform float heightOffset : hint_range(0.0, 1.0);
void vertex() {
vec4 pos = WORLD_MATRIX * vec4(0.0, 0.0, 0.0, 1.0);
VERTEX.x += wind.x * max(0.0, (1.0-UV.y) - heightOffset);
VERTEX.y += wind.y * max(0.0, (1.0-UV.y) - heightOffset);
}
I changed it to version 4.0 and made it sway left and right
shader_type canvas_item; render_mode blend_mix; // Wind settings. uniform vec2 wind = vec2(0, 0); uniform float heightOffset : hint_range(-0.5, 0.5) = 0.0; void vertex() { vec4 pos = CANVAS_MATRIX * vec4(0.0, 0.0, 0.0, 1.0); VERTEX.y += wind.y * max(0.0, (1.0-UV.y) - abs(heightOffset)); VERTEX.x += wind.x * max(0.0, (1.0-UV.y) - abs(heightOffset)) * heightOffset; }zhangxuetu niu
No idea how it works, no explanation at all.
