Finding the Closest Foe

Finding the closest foe character, may want to review the Points section to understand how this works.

function getClosestFoe():Character {
   var closestDistance = Math.POSITIVE_INFINITY;
    var chosenFoe:Character = null;
    var myPoint:Point = new Point(self.getX(), self.getY());
    var foePoint:Point = null;

    for (foe in self.getFoes()) {
        if (foePoint == null) {
            foePoint = new Point();
        }
        foePoint.init(foe.getX(), foe.getY());
        var currDistance = myPoint.distanceSquared(foePoint);
        if (currDistance < closestDistance) {
            closestDistance = currDistance;
            chosenFoe = foe;
        }
    }
    
    foePoint.dispose();
    myPoint.dispose();

    return chosenFoe;
}
