Collision between ground and items

[QuentinIcky]

Hi all ! 

I'm new to phaser, I would like to create an event when items collide to the ground. The items are generated randomely. 
 

//Add items
    emails = level2.add.group();
    emails.enableBody = true;
    emails.physicsBodyType = Phaser.Physics.ARCADE;

//Generate items 
for (var y = 0; y < 2; y++) {
        for (var x = 0; x < 10; x++) {
            var mail = emails.create(5 + x * 94, y * 10, 'email');
            mail.name = 'mail' + x.toString() + y.toString(); // ??
            mail.checkWorldBounds = true;
            mail.events.onOutOfBounds.add(mailOut, this);
            mail.body.velocity.y = 150 + Math.random() * 200;
        }
    }

I tried this :

//Create collision
level2.physics.arcade.overlap(ground, emails, fbiCollect, null, this);

//enemy collect 
    function enemy() {
        console.log('in enemy collect')
        mail.kill();
        scoreEnemy += 10;
    }

But it doesn't work.. So if anyone has an idea

Hi!

Try this:

//Create collision
level2.physics.arcade.overlap(ground, emails, fbiCollect, null, this);

//enemy collect
function enemy(ground, mail) {
  console.log('in enemy collect');
  mail.kill();
  scoreEnemy += 10;
}

I hope it helps!

Thanks for your answer. 
Yes I already tried that, but unfortunately it doesn't work.

I finally succeeded by another way. I added a group of enemies under the character , and made them able to collect falling objects. The collision between them works well.
