Trying to use the above shader on a sprite node for testing purposes. However, it only converts the image into a single color.
This is before applying the shader.
And after.
Really have no idea what I’m doing wrong. Any help would be appreciated.
Here’s the code I’m using the the shader:
shader_type canvas_item;
uniform vec4 whiteColor : hint_color = vec4(0.627, 0.812, 0.039, 1.0);
uniform vec4 lightGreyColor : hint_color = vec4(0.549, 0.749, 0.039, 1.0);
uniform vec4 darkGreyColor : hint_color = vec4(0.18, 0.451, 0.125, 1.0);
uniform vec4 blackColor : hint_color = vec4(0.0, 0.247, 0.0, 1.0);
float min4(float a, float b, float c, float d){
return min(a, min(b, min(c, d)));
}
void fragment(){
vec4 currentColor = texture(SCREEN_TEXTURE, SCREEN_UV);
float blackDistance = distance(currentColor, vec4(vec3(0.0), 1.0));
float whiteDistance = distance(currentColor, vec4(vec3(1.0), 1.0));
float lightGrayDistance = distance(currentColor, vec4(vec3(0.666, 0.666, 0.666), 1.0));
float darkGrayDistance = distance(currentColor, vec4(vec3(0.333, 0.333, 0.333), 1.0));
if (
whiteDistance == min4(whiteDistance, lightGrayDistance, darkGrayDistance, blackDistance)
)
{
COLOR = whiteColor;
}
else if (
blackDistance == min4(whiteDistance, lightGrayDistance, darkGrayDistance, blackDistance)
)
{
COLOR = blackColor;
}
else if (
darkGrayDistance == min4(whiteDistance, lightGrayDistance, darkGrayDistance, blackDistance)
)
{
COLOR = darkGreyColor;
}
else if (
lightGrayDistance == min4(whiteDistance, lightGrayDistance, darkGrayDistance, blackDistance)
)
{
COLOR = lightGreyColor;
}
else{
COLOR = whiteColor;
}
}
HI,
did you realise that the shader is a post-effect? It reads from SCREEN_TEXTURE, not from the sprite’s texture.
