I see several mistakes here.
PixelSearch's color is not 6 digits long. I don't know if 5 digits works, AHK may assume the input was 0x000204 (adding a 0 out front; like how 010 = 10). You've also not included the OutputX and OutputY parameters which are required. Well, technically you did, but not right. See, the first parameter is unambiguously OutputVarX. So you're saying AHK should store the result of the found pixel's X-coordinate in the variable 931 (accessed by
%931%). Pure numbers as variable names are confusing, but, if you want to do that, you can. Same to the Y-coordinate being stored in variable 633. And then that 1053 says this is the X-coordinate of the first corner of the search region; 792 is the Y-coordinate of the first corner. Then 0x00204, as hexadecimal number -- it's 516 in decimal -- is being defined as the X-coordinate of the second corner. And then the 3 is the Y-coordinate of the second corner. So your search region is actually a lot larger than you expected. And finally, the color "Fast" is being used; Fast isn't a color, so it's a variable being evaluated as empty (you never defined it), and I assume that if PixelSearch accepts it, it would treat it as Black. (0x000000.)
There is no If statement, while there's an else statement. Most people use
If !ErrorLevel to indicate a success happened with
PixelSearch; the ! is the logical-not
operator.
Now, as you're in a Loop, that right now has If statement, that would mean (despite AHK giving you an error about an else with no paired If) that you would hit the
Return. That ends the loop immediately. If you want the result to be an indefinite number of k's and then two left clicks and then stop, your code is fine. But if you want the possibility of more than just those 2 clicks, you'd need to get rid of the
Return.
