Hi!
Is it able to control everything in a layer?
Like if i have 2 boxes in a layer, and then i want to write some code like this:

"if(player.hitTestObject(buttom)) {
MYLAYER.x -=1;
}

What im trying so say is… Can I do a hitTestObject that moves everything in a layer?

EDIT: What im trying to say is… Can I control a layer like if it was a object?
