Logical XOR

Flash doesn't have a logical XOR, only a bitwise XOR. That means that you can only do bitwise operations, or swap number and attribute the result to a variable.

Well I needed a Boolean XOR, like the one with Truth Tables that we know from logical programming. Well this little function takes care of this:

public function xor(lhs:Boolean, rhs:Boolean):Boolean {


return !( lhs && rhs ) && ( lhs || rhs );

}



Cheers,
