Working with Scenes! (SpriteKit : Swift in Xcode) Video Lecture | Swift in Xcode: The Complete iOS Development Guide - App Development

hey what's going on everybody today I'm
going to show you how to work with
scenes using sprite kit with Swift in
Xcode so what I mean by working with
scenes is that I'm going to show you how
to transition to a different scene as
well as how to add a start seeing into
your application so let's go ahead and
get started
in this tutorial we will add a new start
scene and also a transition to the
second scene so let's go ahead and get
started alright so let's open up Xcode
create a new Xcode project this will be
a game click Next and the product name
I'm just gonna call this test or
whatever you want to call it language
will be set to swift in technology while
we sprite kit and devices will be
universal click Next and create now
let's make this a bit bigger and let's
head right into our game view controller
dot Swift now the game view controller
you can essentially think of this as
being the manager for all your scenes so
you and here in your main dot storyboard
you can see that you have this one view
controller now this view controller
right here manages the scenes that are
displayed on your application so if you
want to add something into your
application such as the start scene and
whatnot you want to create a new scene
or game scene sks and now let's create
our start saying so let's go right up
here file new file and this will be our
start scene let's head right over to the
resource and this will be our sprite kit
scene like so click Next and we want to
save this as our start scene you can of
course call this whatever you want it's
going to be the first screen that you
want to pop up so now let's actually
create a file that manages the start
scene that we just created so go file
new file go up here to iOS a source and
we're gonna take in Swift file like so
and then up here we're gonna save this
as our start a scene like so now for
some reason it keeps building this file
right out of here so I'm going to click
and drag that right in there and say
finish now inside of the start saying
I'm just gonna basically copy and paste
whatever I have in my game scene dot
Swift so just go in here copy and paste
that right in to start scene like so
change the class name and I'm just gonna
change the class name to start a scene
like so now let's head right into our
start scene die SKS go over here to the
name and I'm gonna call this my start
scene then that should be everything
that we need now let's head right into
our game view
swift and right in here you just need to
edit a few variables so say let scene
equal archiver decode object for a key
you just basically want to change this
to the start scene that we just created
and then down here on the viewdidload we
can say if let scene equal and this will
be our equal to our start scene so just
type that in an archive from the file
start scene then we're going to say as
and this will be as a start scene so now
we are adding this scene as the first
thing that loads when the game is loaded
now just so we can tell the difference
let's go into the start seemed is swift
and I'm just gonna change the text that
loads and our label to some random thing
and I'm gonna build and run and now as
you can see this is the game that
automatically loads so this is the first
scene that loads up now if you want to
transition over to another scene you
need to go down here and I'm just going
to do in the touches began but you can
really do this with any button or
anything so I'm going to go in here to
my start scene dot Swift going to the
touches began and I'm just gonna delete
everything that's inside of there so I'm
just going to say let game scene temp so
this will be a temporary game scene that
we're going to be switching over to so
let game scene temp equal to game scene
open parentheses and this will be our
file named game scene like so so now we
have this game scene created and now we
can switch over to this game scene so
let's go write it down here and I'm
gonna say self dot seemed to view dot
present scene and we're going to present
the scene of our game scene temporary
that we just created then down here
we're gonna say SK transition dot doors
closed with horizontal duration you can
really pick whatever you want and I'm
just gonna make that one second now
right now it's saying something that's
not unwrapped so there should actually
be a question mark right after scene now
let's go ahead and build on this and now
let's go ahead and click and now it
switched over to that other scene so
it's switched right over to the game
scene dot swift because of the way that
we set it up thank you all so much for
