Craft Room

this is the full code in the tutorial hope you find it useful

//VARIABLES
//Drag Object Size
dragRadius = 40;
//Destination Size
destHeight = 100;
destWidth = 100;

//Circle Creation

var circle = new lib.circle();
var test = new lib.test();
stage.addChild(test);
test.x = 1600;
test.y = 200;
//Drag Object Creation
//Placed inside a container to hold both label and shape
var dragger = new createjs.Container();
dragger.x = dragger.y = 200;
dragger.addChild(circle);
dragger.setBounds(100, 100, dragRadius*2, dragRadius*2);
//DragRadius * 2 because 2*r = width of the bounding box

var box = new lib.box();
var destination = new createjs.Container();
destination.x = 850;
destination.y = 250;
destination.setBounds(850, 250, destHeight, destWidth);

destination.addChild(box);

//DRAG FUNCTIONALITY =====================
dragger.on("pressmove", function(evt){
evt.currentTarget.x = evt.stageX;
evt.currentTarget.y = evt.stageY;
stage.update(); //much smoother because it refreshes the screen every pixel movement instead of the FPS set on the Ticker
if(intersect(evt.currentTarget, destination)){
evt.currentTarget.alpha=0.2;
//.rect(0, 0, destHeight, destWidth);

}else{
evt.currentTarget.alpha=1;
}

});

//Mouse UP and SNAP====================
dragger.on("pressup", function(evt) {
if(intersect(evt.currentTarget, destination)){
test.gotoAndPlay(0);
destination.alpha =0;
dragger.alpha = 0;
dragger.x = destination.x + destWidth/2;
dragger.y = destination.y + destHeight/2;
//dragger.alpha = 1;
stage.update(evt);
}else{
dragger.x = dragger.y = 200;
}
});
//Tests if two objects are intersecting
//Sees if obj1 passes through the first and last line of its
//bounding box in the x and y sectors
//Utilizes globalToLocal to get the x and y of obj1 in relation
//to obj2
//PRE: Must have bounds set for each object
//Post: Returns true or false
function intersect(obj1, obj2){
var objBounds1 = obj1.getBounds().clone();
var objBounds2 = obj2.getBounds().clone();

var pt = obj1.globalToLocal(objBounds2.x, objBounds2.y);

var h1 = -(objBounds1.height / 2 + objBounds2.height);
var h2 = objBounds2.width / 2;
var w1 = -(objBounds1.width / 2 + objBounds2.width);
var w2 = objBounds2.width / 2;

if(pt.x > w2 || pt.x < w1) return false;
if(pt.y > h2 || pt.y < h1) return false;

return true;
}

//Adds the object into stage
stage.addChild(destination, dragger);
stage.mouseMoveOutside = true;
stage.update();
