AutoIt Math au3

Thought this may be handy for some others, I use it for bot writing.

Has two features, _largernumber() and _getdistance(),
Both can be used in writing a bot with waypoints.

_largernumber() obviously returns the larger number.
E.g.
_largernumber( 231, 342 )
Would obviously return 342
Syntax: _largernumber ($number1, $number2)

_getdistance() calculates the distance between two sets of co-ordinates.
E.g.

_getdistance (2341, 2231, 8718, 9182)
Would return how far it is from 2341, 2231 to 8718, 9182 (Handy for use of waypoints)
Syntax: _getdistance ($x1, $x2, $y1, $y2)

Code:

#cs ----------------------------------------------------------------------------
 AutoIt Version: 3.2.10.0
 Author:         Dampe

 Script Function: Returns the larger number of 2 givin numbers.
 
	_largernumber ( $number1, $number2 )
	$number1 : First number to check
	$number2 : Second number to check
	Return : Returns the larger number, will return 0 if numbers are the same.
	@error :	1 - Invalid number
#ce ----------------------------------------------------------------------------
	
	Func _largernumber ( $number1, $number2 )
		
		If $number1 > $number2 Then
			;Number1 is larger!
			Return $number1
		ElseIf $number2 > $number1 Then
			;Number2 is larger!
			Return $number2
		ElseIf $number1 = $number2 Then
			;Numbers are the same!
			Return 0
		Else
			;Error
			SetError (1)
		EndIf
		
	EndFunc

#cs ----------------------------------------------------------------------------
 AutoIt Version: 3.2.10.0
 Author:         Dampe

 Script Function: Using Pythagros' theorm, returns the distance between 2 set's of co-ordinates.
 
	_pythagoras($x1, $x2, $y1, $y2)
	$x1 = The first x co-ordinate
	$x2 = The second x co-ordinate
	$y1 = The first y co-ordinate
	$y2 = The second y co-ordinate
	Return : Distance
#ce ----------------------------------------------------------------------------
	
		Func _getdistance($x1, $x2, $y1, $y2)
			
			$largerx = _largernumber ($x1, $x2)
			
				If $largerx = $x1 Then
					$trisidex = $x2 - $x1
				ElseIf $largerx = $x2 Then
					$trisidex = $x1 - $x2
				Else
					$trisidex = $x1 - $x2
				EndIf
			
			$largery = _largernumber ($y1, $y2)
			
				If $largery = $y1 Then
					$trisidey = $y2 - $y1
				ElseIf $largery = $y2 Then
					$trisidey = $y1 - $y2
				Else
					$trisidey = $y1 - $y2
				EndIf
				
				;Pythagoras' Theorm, C2 = A2 + B2
			$distance = Sqrt (($trisidex * $trisidex) + ($trisidey * $trisidey))
			
			Return $distance
			
		EndFunc

hope it helps someone!

You know.. not to criticise you, but there is WAY to much code (and therefore slower) used in those functions.

_largernumber should never return 0 if both numbers are equal.. since you would need an extra check once you call this function..
and if you use Pythagoras.. there is no need to call _largernumber since x^2 will always be positive...

but anyway... everybody who tried to write a bot needs those functions.. so nice sharing

Never looked at it that way, but I'm sure it will hardly make it slower, only in the tiniest.
Thanks for consrtuctive crit though.

I have to agree that _Largenumber should never return 0

Func _Largenumber($s_Num1, $s_Num2)
If $sNum1 > $s_Num2 then Return $sNum1
Return $s_Num 2
Endfunc

but there is already a function like this in autoit (or in math.au3 that comes with autoit)


_Max ( $nNum1, $nNum2 )


also i would like to trow in a subtract function that subtracts the lowest number from the bigest.


Func _Sub($s_Num1, $s_Num2)
If $s_Num1 > $s_Num2 Then Return $s_Num1-$s_Num2
Return $s_Num2-$s_Num1
EndFunc

which then can be added to the _Distance function to make it a lot smaller

Func _Distance($s_x1, $s_y1, $s_x2, $s_y2)
Return Sqrt(_Sub($s_x1, $s_x2)^2 + _Sub($s_y1, $s_y2)^2)
EndFunc



for some reason the code tags doesn't like my $ :s

I'm pretty sure that your double post was completely unnecessary there.. There is an edit button for a reason.. Besides the fact you didn't even spell "doesn't" right the second post.
