Is there another way to checking collision without FlxG.collide?

I'm making a game with Haxe and the HaxeFlixel game engine, and I'm implementing collisions.

I found a way to check for collisions in the HaxeFlixel cheat sheet:

FlxG.overlap(ObjectOrGroup1, ObjectOrGroup2, myCallback);

private function myCallback(Object1:FlxObject, Object2:FlxObject):Void
{
}

But I don't like this style because the callback is separated from the function call. I would prefer this:

FlxG.overlap(ObjectOrGroup1, ObjectOrgroup2, function() {
    //do something
});

I saw this style in JavaScript, but I don't know exactly what it is. Is this possible in Haxe?

And I need this code like this:

if (FlxG.collide(Object1, Object2)) {
    //do something
}

It must return the value (true or false) and it processed by if statement.

Your code snippet for the anonymous function is almost correct, but the callback function for FlxG.overlap() expects two arguments (the objects that collided). Try this:

FlxG.overlap(ObjectOrGroup1, ObjectOrGroup2, function(object1:FlxObject, object2:FlxObject) {
    // do something with object1 and object2
});
