The line follower that... doesn't work

6 posts in this topic

I only started yesterday so excuse the n00biness of the script

Anyway, this is supposed to follow a line but it's not working :)

(My last problem was just that my pixelchecksum test wasn't working... because I mixed up the left and right co-ordinate... :whistle:)

When I tested it... the mouse just went left

Anyway even if you can't help stay and chat cos I'm bored (and sad because my script failed) :lol:

CODE
Global $Paused

HotKeySet("{PAUSE}", "TogglePause")

HotKeySet("{ESC}", "Terminate")

Global Const $Radius = 5

Global $Last = 0

Global $Y

Global $X

Global $X = MouseGetPos(0)

Global $Y = MouseGetPos(1)

Global $left = $X + $Radius

Global $top = $Y + $Radius

Global $right = $X - $Radius

Global $bottom = $Y - $Radius

Global $color = PixelChecksum($left, $top, $right, $bottom)

While 1

Global $X = MouseGetPos(0)

Global $Y = MouseGetPos(1)

I just realised I could have shortened that script by making the horizontal and vertical variables in the loop... and had the single function... ah well... it still wouldn't work anyway so I'm not going to bother changing it now

I just did shorten it anyway

Maybe explaining what you actually want your program to do in more detail than you already did would help. All anyone could do now is run your code and see what happens, but most probably no-one is "going to bother" to do that without some more information. Kindly inform the readers of this forum in detail what you expect your code to do, and where it goes wrong.

Even better would be to make a small test code which does nothing else than reproduce your problem, so other people know what to look for quicker. This will be much more inviting to troubleshoot.

Oh, and I hope your blocked nose gets better! :whistle:

I didn't explain?

I'm trying to make a program that makes the mouse follow any line that is a certain colour and width (set by $radius)

and the way i went about it was to imagine a circular object travelling on this line - so it tests the four directions for the colour and moves if its the same as the original colour... and so that it doesn't backtrack it doesn't go the same direction twice in a row

I can't think of any way to make it simpler :whistle:
