<br> Ops, copy&paste problem. The correct rule is:<br><br>rule "get closer object"
<br>when<br> $a : Agent( $num1 : num )<br> $b : Poste( $num2 : num )<br> not Poste( $num3 : num -> ( abs( $num1, $num3 ) < abs( $num1, $num2 ) ) )<br>then<br> // do something<br>end<br><br> []s<br> Edson

<br> Hi,<br><br> If you are using 4.0.0.M2, I think this will do the job:<br><span lang="EN-GB"><span><br></span></span>function abs( int a, int b ) {<span class="q"><br> return Math.abs( b - a );<br>}<br><br></span>
rule "get closer object"
<br>when<br> $a : Agent( $num1 : num )<br> $b : Poste( $num2 : num )<br> not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1, $num2 ) ) )<br>then<br> // do something<br>end<br><br> If you are using
3.0.x, then it would be like:<br><br>function abs( Integer a, Integer b ) {<br>
return Math.abs( b.intValue() - a.intValue() );<br>
}<br>
<br>
rule "get closer object"<br>
when<br>
$a : Agent( $num1 : num )<br>
$b : Poste( $num2 : num )<br>
not Poste( $num3 : num -> ( abs( $num1, $num3 ) < Math.abs( $num1, $num2 ) ) )<br>
then<br>
// do something<br>
end<br>
<br> Hope it helps. Let us know if it works the way you need.<br> <br>
