My iOS game on xcode on macbook air - development update [X5cF7uRkQtg]

Hello and welcome back to X-Coding

with Daniel. So this is where my game is

right now. I was mainly doing

the artwork yesterday. I created a few new

zombie types, and I haven't updated this

one. We'll do that later. Okay, so I've

updated the zombie graphics, and I've also

added like a walking animation. So you can

see they're like walking or trodding—

trod— I don't even know the word. They're

walking down the screen, and when they

touch the tank, they die. You see,

you can run them over. Now if, if the

zombies get to the bottom of the screen,

then it's game over. Now this is just

temporary. I'm going to design the whole

game over restart button myself later. So

what I did— so when you press restart,

you can restart, and then it's all

restarted. Okay, but there's still like a

bug when I press the restart button.

Watch.

Oh, it seems okay now, but sometimes it's

like a strange bug. See, it's bugged

now. It's not going to game over.

Oh, there we go. For some reason, the game

over happens later. Anyway,

so what I did was I

created a new void called zombieWalking,

and zombieWalking is located here.

zombieWalking. So basically it's an

NSArray images, and then I put in these

new images of them walking. Like this,

and basically I just flip the image. So I

have blue zombie 2 and blue zombie 1,

and the only difference is the mouth is

open on one. The rest of it's just a

flipped image, so it looks like they're

And then I added that animation code for

all these monsters that match that

graphic. And I also made a zombie walking

2 for the, for the second set of zombies.

So they will walk, and this is the speed

of the— so if I make this a higher number,

it should go slower, and if I make it a

smaller number, it should go faster. And

repeat count, if you set it to 0, then the

repeat count is set to infinite, so it

just keeps animating over and over.

What else did I do?

Yeah, this is the code for— put

it— no, I made this one called Tank

Runover. What it basically is,

is if I can show you.

Okay, so I put an ImageView here, but I

didn't assign an image to it. So when you

load the game, it's actually invisible,

but it's still actually there. So if I

set, if I set this one to bullet, so it's

actually an image, and then I run the

game, you can see what's happening to it.

It's actually following the tank. So if

the zombies touch this part of the tank,

they die. Because before,

they were touching the front of the tank

and dying, and that doesn't really make

sense. It was just like they were touching

the front of the tank. So you can

see the orange block, and it follows the

tank as you go along.

So see this zombie coming along? We can

just run him over like this. Run these

guys all over.

So at the moment, everything's working

fine. Except that the game is way too

easy. It's just so easy to kill these. So

what I might do is slow the tank speed

down. If I— I'm not sure how to do that

yet, but there must be a way.

Also, I want to add— I want to at least

double the number of zombies on the

screen, and I'll make some of them, maybe

a third of them, walk a lot faster.

So you really have to like race across the

screen to try and shoot them down.

And basically the goal of the game is if

you kill all of the zombies, you'll finish

the level, and then it will go into level

2, or wave 2, and wave 2 should be more

difficult. Also, I want

power-ups. So power-ups would randomly

appear on the track, and you'd have to

take the tank over to it to pick up the

power-ups. But the trick is the power-ups

won't stay there for more than a few

seconds, so you really have to go for

them. And if you're going for the

power-ups, it could put you in a bad

position because a zombie could sneak past

you. And I haven't really decided what

kind of power-ups yet. I guess we could do

like all kinds of weapons, like we could

have like a razor blade that attaches to

the front of the tank so all the zombies

in front of it die.

Or we could have a more powerful cannon

that just tears across the screen,

killing all the zombies in its path

instead of just one. Also, we could have

like randomly placed traps on the field,

like explosive barrels.

I'm not really sure how to do like an

explosion animation, that could be quite

tricky, so we might do something simple

like a spike trap. So spikes

zombies. That could be quite good.

Also, I want to do like— I wanna have like

a house here, and it'll be like an

obstacle. So if you shoot the house, it

would like start getting destroyed, but

the bullets can't go past the house and

the zombies can't go through the house.

So I'm gonna have— I'm going to have to

write code so that the zombies walk around

the house. I think that could be quite

interesting. So yeah, that's my

game so far. What do you think? If you

have any ideas, like game ideas, I'm all

ears, so leave them down in the comment

section. And actually, I bought

a MacBook Pro and it arrived today, but

it's still like updating. It's downloading

Xcode right now, but it's taking ages, so

So for now I'm still on my MacBook Air.

But the MacBook Pro, it feels so much

faster. Even opening programs and stuff

like that is just instant. The extra RAM

really helps. So I'm looking forward to

using Xcode on it because my game is

getting more complex and it feels like

it's starting to slow down, like the

program. I mean, look at Activity Monitor.

I'm using swap memory because I've used up

all the physical memory. Xcode uses about

500, sometimes uses a gigabyte of RAM.

So yeah, what else do I need to do? I need

to create more zombies because at the

moment there's only 3 types. Oh, I was

going to show you the new zombie I made.

Hold on. Okay, so where was it?

I haven't actually downloaded it yet.

Let's see, so many tabs open.

So this was one of the zombies, and this

is the second one.

So this, this zombie looks kind of sad,

doesn't he? Zombie 2A and Zombie 2B. So it

kind of looks like he's walking. Okay, so

we download these.

And then go back onto Xcode, then go

Finder, then go into your Downloads. It

should be there. And then just select them

both and then drag them down into

Supporting Files. Then just do Finish.

And then what we do is we select all the

zombies we want to change.

And then we change the image to

zombie2a.png. Okay, so they

look kind of squished, so just choose one

and resize it.

Don't make it too big.

I think this could be a good size, like

this. Make him

a bit shorter.

Okay, so he is 60

pixels by 65, so we just select the rest.

60 by 65, was it? And just

change it here, and that changes all of

And then we have to do the animation. If I

can select him. It is a bit tricky to

select them because there's so many images

on the screen, and they kind of overlap

each other. Let's move him up.

Okay, so what we need to do now, we need

to declare a new animation. Because we

need a separate animation block for each

one. So we'll call it zombie walking 3.

And then what do we do?

Basically, we want to copy zombie

walking, just copy it all,

and then put it under number 2 to make it

a bit tidier. It's a complete mess, I

know. So messy.

Okay, so it's up here. Don't forget close

curly brackets and change this to 3.

So we need to find those monsters that we

want to animate.

So where are they? We have monster5,

monster10, and Monster 4 and

9. 5, 10, 4,

9. 5, 10, 4, 9. 5,

10, 4, 9. 5,

10— whoops.

4, and then 9, was it?

Okay, and then we need to activate

it, so In

IBAction Start, so this is what happens

when you click on the Start button, we do

self.zombieWalking3,

close square bracket, and then semicolon.

I think that is all. See if

we're missing anything.

Movement. Okay,

let's test it.

Okay, the moment of truth. Oh,

they've disappeared. Okay, that isn't

what I expected to happen. Hang on.

Okay, something's really strange. Oh,

I know, I know, we didn't— so stupid— we

didn't change this bit for the images. So

yeah, this needs to be changed to— what

was it— zombie2a.

This is like the most important part. How

could you leave it out? Zombie2a.

And then we could change it back to

Okay, should be fine now.

Yep, they are walking along.

Look at this guy, he's super fast, he

wants to die first. Squish.

So they all get squished.

Oh, these are the slow ones.

Boom! So yeah, it's kind of easy at the

moment, not really a challenge. I guess

I'll add more zombies. It's kind of— it's

kind of time-consuming because You have to

draw the zombies, draw the animations. I

still have to draw the death animations

because at the moment I only have one for

the blue zombie, which is just like him

lying in his own puddle of blood.

So takes a lot of time,

but it's nice because I can do all the

artwork myself and I can do all the coding

myself. Still not sure how to do sound. I

have to do that later. I'm not sure when

I'll have a look at sound. I have to look

up— I have to look up a tutorial.

I guess I could buy some sounds, or I

could make the sound myself. I'm not

really sure what the rules are. I mean,

what if I just record an explosion sound

off of YouTube and use that? Is that

illegal? I don't know.

Also, I'm not really sure what I should do

with this gun. At the moment it's like a

fireball. I guess I could do my

own version of a fireball, or I

could do a cannonball. Tanks don't really

shoot cannonballs, do they?

So yeah, thanks for watching and If you're

interested to see how this game turns out,

just subscribe to my channel. And then,

because I keep— I'm going to keep

uploading these videos to like document my

progress as I journey down this path of

iOS game development. Anyway, see you guys

later.
