Colour checking and reseting

Programming Questions

I am trying to get a function that checks the colour of a shape, and if it's red value is above z, and another shape is inside it, then the shape is reset to position x and y.

I am having really trouble writing this and have been struggling for several days. Code that peers are telling me to try seem to do nothing, here's the latest

void resetCheck()

{

loadPixels();

redValue = get (int(PosX), int(PosY));

if (red(redValue) >= redThreshold)

{

PosX = 25;

PosY = 25;

}

The only problem with this I see is that PosX and PosY are the center positions of a yellow circle, and not of the flashing squares behind them that I want the red value of,

this function is contained in a class and the flashing square in another class

The Class for the block is as follows

class hazardBlock
{
float redValue, greenValue, aa, ab, r;

    void colourSwap()
    {
      r = random (.0005, .125);
      aa = aa + r;
      ab = cos(aa);
      redValue = ab;
      greenValue = ab;
      redValue = map (redValue, -1, 1, 0, 255);
      greenValue = map (greenValue, 1, -1, 0, 255);
      fill (redValue, greenValue, 0);
    }
    void drawBlock()
    {
      noStroke();
      colourSwap();
      rectMode(RADIUS);
      rect(0, 0, 25, 25);
    }
}

I have a varibale in the class of the object I want to reset if the square has a certain red fill called redCheck and for testing sake I'm using the get function for pixel (51, 1) which i know to be flashing red or green and when I try a println(+redCheck) I get numbers ranging from -1,400,00 and -200,000. Sometimes these values have been much larger or much smaller.
