simple java wow image bot

[barathrumm]

Hey got inspired of a few other threads here and decided to start building a java wow bot that read info from the screen directly, by reading pixelcolor, however i have run into a little snag, i need to parse the a square of the game area for a strong yellow color rgb(>150, >150>, <10)

to do this i build a multilevel array with these two functions and then parse each item and checks if they fir the bill on the yellow color, thing is, this is a very slow way of doing it with a complexity(se code) at 30 it takes atleast 10 seckonds, which is alot thinking that this code is going to be run every
0.2 seckond when looking for a target, any help to optimize this would be of great help

public ArrayList<ArrayList<Color>> getColorGrid(int fx, int fy, int tx, int ty, int complexity) {
	ArrayList<ArrayList<Color>> result = new ArrayList<ArrayList<Color>>();
	while (fy < ty) {
		result.add(getColorLine(fx, tx, fy, complexity));
		fy = fy+10+complexity;
	}
	return result;
}

public ArrayList<Color> getColorLine(int fx, int tx, int y, int complexity) {
	ArrayList<Color> colorList = new ArrayList<Color>();
	while(fx < tx) {
		colorList.add(robot.getPixelColor(fx, y));
		fx = fx+10+complexity;
	}
	return colorList;
}

If i knew anything about java programming it might be cool.

just for anyone who might find and need the help to optimize this, the answer is to take a screenshot save it to a buffered image variable, and then parse the buffered image, instead of grabbing pixels with the robots class directly from the screen.

made my code go from 4-6sec execution to less than half a second, with a complexity(refer to code in my first post) of 30,
well about the same time with a complexety of 0 actually, in any case it is MUCH better.
