How do I make something like a floor immovable?

[A Derpy Cat]

I am new to coding and I need to know how to make any object or sprite etc. immovable.

something like this works:

// create a sprite without an image as a child of the skeleton
var floor = game.add.sprite(0, 0, null);

// enable physics so collision applies
game.physics.arcade.enable(floor);

// add a little offset so it's along where the skeleton is standing
floor.anchor.setTo(0, -1);

// create a floor long enough for the particle to land onto and not fall off
floor.body.setSize(400, 1, -200);

// we don't want the floor to move when the collision kicks in
floor.body.immovable = true;
