Hello,
Please format your code as a courtesy to the community helping you:
https://discourse.processing.org/faq#format-your-code
Resources:
- https://processing.org/reference/libraries/ There is a sound library.
- Sound \ Processing.org
And many examples in the Processing application to try:
Give it a try!
:)
what did i do wrong in formatting this time i thought i did it proerly?
go back, edit your post using the pen symbol underneath it.
Select the entire code section and click </> symbol in the small command bar
Looks

Your code is confusing.
What is your intention?
As has been said please write your goals and questions in the text section and not only in the title.
i am screen recording my screen, and want it to see if a specific color is on that screen and if it is it has to play a sound
with size(1500, 3000); there is hardly much else on your screen than your Sketch?
Why do you make so many screenshots? ONE should be enough. In setup().
And then go over it with a nested for loop (2 fors) and check the color.
When you just say x++ y++ in the same frame of draw() you’re only testing the diagonal points of the center line…
but how do you play a sound when (colorFromGet== pas) with this code?
seriously? Your code can’t find a color as I just explained. It doesn’t search your screenshot.
Read Images and Pixels \ Processing.org
Sound (WHEN and only when you developed your Sketch, now it’s of no use): SoundFile \ Language (API) \ Processing 3+
doesnt it scan every line one by one if you add 1 to x and y the whole time?
err… NO
first of all, read the tutorial there is a code how to go over each pixel in an image/screenshot
think about it first time draw() runs both are 0, second time both (!) are 1 etc. - you only scan the diagonal “” of the image
what you need is:
- x is 0 (first row of the image) y goes from 0 to height (x stays 0);
- x is 1 (2nd row of the image) y goes from 0 to height;
- x is 2 (2nd row of the image) y goes from 0 to height;
That’s achieved with a nested for loop
for (x....................
for (y........
COMPARE ---> play sound
}
}
what is a nested for loop. im learning with a youtube channel and i havent heard about that yet
read the tutorial
it has an example without nested for loop, just ONE for-loop
QUOTE
Take the following simple example. This program sets each pixel in a window to a random grayscale value. The pixels array is just like an other array, the only difference is that we don’t have to declare it since it is a Processing built-in variable.
size(200, 200); // Before we deal with pixels loadPixels();
// Loop through every pixel
for (int i = 0; i < pixels.length; i++) {
// Pick a random number, 0 to 255
float rand = random(255);
// Create a grayscale color based on random number
color c = color(rand);
// Set pixel at that location to random color
pixels[i] = c;
}
// When we are finished dealing with pixels
updatePixels();
(this code changes the pixels, you only want read them. So change this. But it’s the correct way to go through ALL points. Also it works on the Sketch surface and not on an image, but the principle is the same, see below)
as explained here: PImage \ Language (API) \ Processing 3+
just search the screenshot image and NOT display the screenshot and DON’T search the screen using get directly.
use loadPixels() and get on the image directly
- see PImage \ Language (API) \ Processing 3+ for both
