Hi,
I am just looking for someone that would explain how "pixelsearch" and "pixelgetcolor" work.

I have read over the section in the guide on it, but, being 13, and fairly new at this isn't helping understand it.

PixelSearch
Searches an area of the screen for a colour you want.

PixelSearch, OutputVarX, OutputVarY, X1, Y1, X2, Y2, ColorID [, Variation, Fast|RGB]

OutputVarX/Y: The variable to store the x/y-coodinate of the point where the colour was found.
X1, Y1: The toper-leftmost point where the colour searching should start from.
X2, Y2: The bottom-right point where the colour searching should stop from.
ColorID: The colour code of the pixel you want to search for.
Variation: An 'allowance' for a different intensity of colour.
Fast|RGB: Making this 'Fast' means it will look for the colour faster, making it 'RGB' means it will use another method of searching.

Example:
You want to search for the colour Red on a section of the screen and move the mouse to it.

Don't let age stop you. I've got plenty of teenage friends who are very good at programming. It just takes some dedication and experience. As for those particular functions, I can't tell you much more that isn't in the docs, but I can try to explain it more simply.

PixelSearch: Finds the specified color in the specified area, and returns it's coordinate. The output is returned in the OutputVarX and OutputVarY parameters. X1 and Y1 are the coordinates for the upper left of the area to search in, and X2 and Y2 are the lower right coordinates. ColorID is the color to search for, in BGR (Blue-Green-Red) format. You usually don't have to worry about the last two parameters, Variation and Fast|RGB. If you have your screen set higher than 16-bit color, the Fast parameter is usually OK to set, and Variation helps with colors that may vary (Like, say, a winamp skin with a brightness setting, or a health meter in a game).

PixelGetColor: This is PixelSearch's counterpart; rather than finding the coordinate of a color, it finds the color of a coordinate. It's also simpler to use. The only OutputVar unsurprisingly returns the color of the pixel whose coordinate is specified in the X and Y parameters. The RGB parameter, if specified, returns the value in RGB rather than the default of BGR.

Edit: Titan beat me to it. Oh well, the more the merrier!

Thank you, alot, helped out quite a bit.
If i wanted to find the color where ever my mouse cursor was, what would i use for the coords?

Don't use "is" and "is not" to compare a variable to a value. Instead, use = and <>:
