Cannot set collide with rotated group

Hi all,

 

I started to learn group in Phaser. And here is my code:

function onCreate() {    var arr = [];    game.stage.backgroundColor = 0xffffff;    boxes = game.add.group();    blue = boxes.create(0, 0, "blue");    yellow = boxes.create(blue.width, 0, "yellow");    red = boxes.create(0, blue.height, "red");    green = boxes.create(blue.width, blue.height, "green");    arr.push(blue);    arr.push(yellow);    arr.push(red);    arr.push(green);    for (var i = 0; i < arr.length; i++) {        game.physics.arcade.enable(arr[i]);        arr[i].body.immovable = true;    }    boxes.enableBody = true;    boxes.physicsBodyType = Phaser.Physics.Arcade;    boxes.x = game.width / 2;    boxes.y = game.height / 2 + 100;    boxes.pivot.x = blue.width;    boxes.pivot.y = blue.height;    boxes.scale.setTo(3);    circle = game.add.graphics(0, 0);    circle.beginFill(0xffffff);    circle.drawCircle(boxes.x, boxes.y, 60);    mask = game.add.graphics(0, 0);    mask.beginFill(0xffffff);    mask.drawCircle(boxes.x, boxes.y, 100);    boxes.mask = mask;    drop = createDrop(game.width / 2 - 8, -30);    cursor = game.input.keyboard.createCursorKeys();}function onUpdate() {    timer++;    if (timer == 150) {        //createDrop        ....    }    // check game input to rotate boxes group    ....    game.physics.arcade.overlap(drop, boxes, onCollide, null, this);}function onCollide() {    // nerver hit    console.log("collide");}function createDrop(x, y) {    // create random drop color    ....    if (drop != null) {        var number = 100 * (rand * 0.5 + Math.random());        drop.anchor.setTo(0.5, 0.5);        drop.scale.setTo(0.5, 0.5);        game.physics.arcade.enable(drop);        drop.body.gravity.y = number < 100 ? 100 : number;        console.log(drop.body.gravity.y);    }    return drop;

The problem here is the function onCollide() is not hit. Can you give me a hint to solve this?

Thank you
