INSTRUCTIONS
First dodge all 15 snowballs!
Then shoot the Ice Giant in the head to kill him.
*If you are hit, you must Refresh in order for game to work right.

CONTROLS
Arrows : move you up, down, left, right
Space Bar : fires missile

STORY
In northern Alaska an evil as old as the earth has awoken.
The town of Smallville is under attack by an Ice-Giant.
Its up to you, Guy Malone, to save Smallville from destruction.

here's the code used to construct it..

// collision check - snowball to guy relationship
function collisioncheck() {
// list variables for snowball & guy's circles
var p = guymalone.getlcircle();
var d1x = snowball._x - p.x;
var d1y = snowball._y - p.y;
p = guymalone.getrcircle();
var d2x = snowball._x - p.x;
var d2y = snowball._y - p.y;
// the math
var d1 = Math.sqrt((d1x * d1x) + (d1y * d1y));
var d2 = Math.sqrt((d2x * d2x) + (d2y * d2y));
// set touch threshold - any separation less than this implies touch
var touchThreshold1 = snowball.radius + guymalone.leftcircle.radius;
var touchThreshold2 = snowball.radius + guymalone.rightcircle.radius;
// check distance (separation) against threshold
if ((d1 <= touchThreshold1) || (d2 <= touchThreshold2)) {
// hit! collision detected
guymalone.gotoAndPlay("death");
}
//
// **** missle against head relationship
// distance in x dimension
var dx = rocket._x - head._x;
// distance in y dimension
var dy = rocket._y - head._y;
var d = Math.sqrt((dx * dx) + (dy * dy));
// set touch threshold-- any separation less than this implies touch
var touchThreshold = head.radius + rocket.radius;
// check distance (separation) against threshold
if (d <= touchThreshold) {
// head hit! collision detected!
icegiant.gotoAndPlay("icedeath");
}
}
// associate collision check with onEnterFrame
_root.onEnterFrame = collisioncheck;

//limit the area that Guy Malone can fly
var radius = guymalone._width * .2;
//
