Bodys

Bodys are the object that a Universe itself is made of. Bodys is a data object that is made up of components. You can create new bodys by calling the Body() method on a Universe. This function takes a table like so:

local body = Universe:Body({})

Technacly though, in Luau if your passing a single string, or table into a function you don't need the parantheses meaning that these mean the same thing:

--This
local body = Universe:Body({})
--Is the same as
local body = Universe:Body {}

This is the recomended way to create Bodys in Comet and you will see it throughout the rest of the tutorials.

Parents

Parenting allows you to control how an object behaves with other objects. By default, a body will not be parented to anything, this is why Comet goes with an add() method, which takes an input of the parent and the child.

--You can parent a body to the universe
Comet.add(Universe, {
    Universe:Body {}
})

--Or other bodys
Comet.add(otherBody, {
    Universe:Body {}
})

You could also use the Comet.Parent() method to parent a single child, but its recomended to only use Comet.add() as its more powerful.

Abstract

The reason you are able to Parent a body to the Universe is because it is also is a Body object, meaning pretty much all methods that work on bodys will work on the Universe.

Destruction

Whenever your done with a Body you can use the Destroy() function attached to Comet to destroy it.

Comet.Destroy(body)

This will destroy the Body and all of its decendents.
