FAQs on Programming a 2D Crossy Road Game (Scoring - Swift in Xcode) Video Lecture - Swift in Xcode: The Complete iOS Development Guide - App Development
| 1. How do I score points in the Crossy Road game? |  |
Ans. In the Crossy Road game, you score points by successfully guiding your character across the road and avoiding obstacles. Each time you safely cross a road or jump over a hazard, you earn points. As you progress further in the game, the difficulty level increases, and you earn more points for each successful move.
| 2. Can I implement a high score feature in my Crossy Road game? | |
Ans. Yes, you can implement a high score feature in your Crossy Road game. To do this, you can create a variable to keep track of the player's score, incrementing it each time they successfully complete a move. Additionally, you can store the highest score achieved in a separate variable and update it whenever a new high score is attained. Displaying the high score on the game screen will provide motivation for players to beat their previous records.
| 3. How can I display the score on the game screen in Xcode? | |
Ans. To display the score on the game screen in Xcode, you can create a label or text field and position it appropriately on the screen. You can then update the text of this label or text field with the current score value whenever it changes. By connecting this UI element to your code using outlets, you can easily update the score display in real-time.
| 4. Is it possible to implement a multiplayer mode in the Crossy Road game? | |
Ans. Yes, it is possible to implement a multiplayer mode in the Crossy Road game. To do this, you can use networking concepts such as Game Center or Bluetooth to connect multiple devices and allow players to compete or collaborate in real-time. You will need to handle syncing game states, scores, and movements between the connected devices to ensure a smooth multiplayer experience.
| 5. Can I customize the scoring system in my Crossy Road game? | |
Ans. Yes, you can customize the scoring system in your Crossy Road game according to your preferences. You can assign different point values for different actions, such as successfully crossing a road, jumping over a hazard, or collecting power-ups. By adjusting these point values, you can create a scoring system that aligns with your game's mechanics and desired level of difficulty.

hey everybody welcome to part 3 of how
to create your own Crossy road
application with Swift in Xcode today
I'm going to show you how to add score
into your application so let's go ahead
and get started so let's open up our
Crossy Road Xcode project and let's make
this a bit bigger and head on into our
viewcontroller.swift now I am going to
program eclis do this and if you want to
stay tuned till the end of this video
this was gonna be just a really short
video as I'm just gonna show you how to
do the score now I'll show you at the
end of the video why I'm program eclis
doing it but right now let's save our
score label is equal to a UI label open
parentheses close parentheses so now we
have our score label created then we
also want to create a score so we can
say var score is equal to and this will
be just an integer so this will be equal
to an integer open open parentheses
close parentheses and then head down
here into your viewdidload and now we're
going to actually edit our score label
that we created and set it to a certain
size we can do this by saying score
label equals UI label and then we're
going to say open parentheses and it's
going to give you these two these three
types of what you want to say so our we
want this to set to a frame and this
frame is going to be fit inside of a cg
rekt so we're going to say cg rekt make
our x value will be actually if we head
on into our main dot storyboard and open
up the assistant editor we can I can
actually show you exactly what our X&Y
value are going to be we can just take a
label put it inside of our main dot
storyboard we are not going to be using
this label but this is just going to be
for reference if you want to add it
anywhere on your scene so I'm going to
take this label and then head on in to
our size inspector over here and you
will see that the x value is 16 the Y
value is 20 the width is 42 and I'm
gonna make the I'm going to make the
width a bit bigger
like so and now so this would be a 77
and 21 so now we can plug those numbers
right in here so it's 16 2077 21 16 2077
and 21 so now if we go back to our label
see if those matched up okay so we have
our X X Y width and height so now we
have those properly made and now we can
actually take the score label and we're
going to add this into our scene in just
a moment but we'll add this score label
right into our scene in just a moment
because if you actually built and ran
this right now it would not show up your
in your scene so we can say before we do
that we need to say score label dot text
alignment will be equal to NS text
alignment dot Center so we're going to
Center whatever text we put in there and
then when the view loads I personally
just want to do this you don't have to
but it's going to be I'm going to make
the text so I'm going to say score label
dot text equal to zero wrong button okay
so now we have our score label text
equal to zero soon as the view loads and
then now we're going to add this into
our scene so we can say our self dot
view dot to add sub view and we're going
to add the sub view of our score label
now I know it's not a view but we're
adding basically a child or we're adding
a property into our view or an object
into our view not property so now we can
take this sub view I mean this is the
sub view so we can add we're adding the
sub view and now if we actually built an
around this we will get our player
building properly alright so as you can
see I have a label up here and I forgot
to erase that label on my main dot
storyboard now let's build and run this
again and now as you will see I have the
score label building on to our cross
erode hit project and it's just going to
be centered right over here exactly
where I wanted it and now if we were to
click as you can see there's no problems
going on which is good but
that's not where the problem lies so we
can go in down here into our move and we
can say score plus plus and then our
score label so basically in our move if
you don't remember it is a it is called
anytime we are tapping the the screen
itself so we're calling this every time
we tap the screen we're going to add one
to the score and then we can take the
score label and actually add this score
text on to our scene so now we can say
score label dot text will be equal to
open quotation mark close quotation mark
and inside of these quotation marks you
just want to have a slash open
parenthesis closed parenthesis and this
is going to allow us to add a variable
inside of our text so we can put inside
of these parentheses score so now as the
score is being added to or as soon as
this function is called we are going to
also call this and we're going to add
this the score into our score label dot
text so now if we built and ran this you
will see that our score is building and
running properly so now we're adding one
to every time we click the screen and
now there's enough there's a cool thing
that you can do so if you're done if you
don't want to have just plain old you
can't buy one every time you could say
score plus equals ten or however many
points you want to add on tearing into
the score every time that you click this
move function so now you're actually
going to be counting by ten any time you
tap the screen and if you made the label
the wide enough it's going to keep
continuing on until it doesn't fit in
the label or whatever you want so now we
have our score it's building or running
in there and that is how we do our score
now that is it for this tutorial now I
have been trying to figure this out
myself for a while and I just want to
this is explaining why I didn't use a UI
element so if I were to actually take
this score label delete that and we can
delete that out of our viewdidload as
well we could take this score label this
label down here we're going to add that
into our scene we're gonna make it a bit
bigger going to our attributes inspector
Center it this is just a test
then right-click or ctrl click and drag
from our label good and we're going to
insert an outlet and this outlet will
just be our score label connect and as
you can see it's going to update
everything so now if we were to actually
build and run this we will have score
going into our label but there's a catch
now as you will see I don't know whether
this is a problem with with Swift or
with Xcode or whatever but we have this
and it's counting up by 10 every time
but it's also like resetting the scene
every time I explained this in my last
video I don't know I didn't know what's
going on I still don't know what's going
on but I figured out how to fix it and I
did and that was the first part of this
tutorial
