I'm trying to darken every pixel in the frame by a fixed amount every time draw() runs. How do I accomplish this?

Currently I'm using

for(int i=0; i<width*height; i++)

{

pixels[i] = pixels[i] << 1;

}

But that gets weird because it just kinda messes with the colors until they go to black.

Is there any way to access the HSB, RGB, or hex values of a pixel returned from get(x, y) or pixels[i]?

Thanks in advance.

There is:

red( pixels[i] );

green( pixels[i] );

blue( pixels[i] );

BUT... This isn't what you want. Instead, try:

int darkness_level = 5; # Higher -> darker

fill( 0, 0, 0, darkness_level );

rect( 0, 0, width, height );
