    Default returning color of pixel in loop

    Hello everyone!

    Ok, here is part of my code:
                        Color c = robot.getPixelColor(663, 60);
                        Color red_Battle = new Color(231,50,42);
     
                        if(c.getRGB() == red_Battle.getRGB()){
     
                            Color end2 = robot.getPixelColor(6, 538);
                            Color zero = new Color(5,5,0);
                            while(end2.getBlue() == zero.getBlue()){
     
                                Color spd = robot.getPixelColor(72, 572);
                                Color nula = new Color(63,61,41);
     
                                if(spd.getRGB() == nula.getRGB()){
                                    r.delay(50);
                                    r.keyPress(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyPress(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyPress(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_F);
                                    r.delay(800);
                                    r.keyPress(KeyEvent.VK_A);
                                    r.delay(1000);
                                    r.keyRelease(KeyEvent.VK_F);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_A);
                                    r.delay(50);
                                    r.keyPress(KeyEvent.VK_R);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_R);
                                    r.delay(50);
                                    r.keyPress(KeyEvent.VK_R);
                                    r.delay(50);
                                    r.keyRelease(KeyEvent.VK_R);
                                    r.delay(1000);
                                    System.out.println("Speed 0 km/h.");
                                }
                                 end2 = robot.getPixelColor(6, 538);
                             }
                        }

    First color returning in statement IF is working fine.
    Second color returning in statement While is working properly too.
    But third not - statement IF is not running when pixel on 72x752 has the same RGB value as variable 'nula' (63,61,41).

    I really can't find where is the problem

    Default Re: returning color of pixel in loop

    Try debugging your code by adding some printlns to show the values of all the variables as they are set and tested.
    For example assign the values returned by the get methods to variables and print their values before testing them in the if statement. The print out will show you the values that the program is seeing and using and should help you understand what the program is doing.

    Default Re: returning color of pixel in loop

    Thank you, it helped me. I used

    System.out.println("Value of color is "+ spd);

    and it gave me different value of color. I tried to use them and now it is working fine.

    So far I was using PrintScreen button to take a photo of my screen and then Photoshop to find out coordinates and color of exact pixel.
    Until now I didn't have a problem with that.
