Color detection for a given image?

in Programming Questions • 1 year ago

In my zombie game, the zombies are allowed to move only when the space in front of them is empty, and in this case, if the pixel matches the gray background. However, I do not know how to find the color of the pixel in front, though the get() method under the pixels section hold potential.

Does anyone know how to detect color, or can explain to me how the get() method works and what it returns?

Maybe

color c = img.get(x, y);
// here you should specify coordinates x and y of that part of image img you want to sample

now that you have color information, it should be pretty easy to detect its value

if ((red(c)==204) && (green(c)==204) && (bllue(c)==204)) doSometing();
// this particular if-statement detects if all of three color values of that pixel
// are the same which would mean the color is grey (greater number, lighter color) and
// I think 204 is the value of the background..
// also "if (c==204)" could work


good luck
