adding sounds to buttons on xcode making a game on macbook pro!

Hey guys, I want to show you my app so

far. I've been trying to get the sound

working, but I haven't been very

successful. I've managed to make one

button make a sound. Listen.

But I don't know how to make it play a

second sound, so I could have start button

play a different sound. See, it's playing

the same sound. And this is what the game

looks like so far. I'm not sure if these

buttons are a bit confusing. I think

they're kind of obvious. I mean, this

one's ammunition, this one's repair, this

one's speed. I don't know if that's

obvious enough. Maybe I should put like

labels what they are, but I'm kind of

running out of space because look, when

you press turrets, this takes up the

bottom space, see?

And these walls take up this space. And

then when you press start, this space is

going to be taken up by the shooting

button. So I don't really have much space

left,

which is why I'm not sure about putting

ads on the game, because if I put banner

ads, it's going to block— I guess I could

put one down here and it won't really make

too much difference because there's not

much, but then you can't see the cool tank

shadow. So when you press start, I've made

a sound effect. So when you— when a zombie

gets hit by the bullet, it makes a splat

sound. But for the first

time, first shot, it doesn't make the

sound, but the second it does. See,

so it makes a splat sound,

which is quite funny.

I'm not sure how to put like a second

sound for the cannon.

I guess we could experiment a bit on the

ViewController.h. So what I've done is

I've made— I'm guessing these are like

on the h where you do IBOutlet. So that

first sound is called playSoundID. So I

made a second one called blood1, and I

want— no, not this one.

I want— try again— MainMenu.

I want this button to make the blood

sound, and this can make the gun sound.

So I'm guessing we have to do a second IB

action, which is what I've done here.

We'll just call it Play Sound Music

Button. So this one's linked

to this one, right? So I want this one to

link to this one. So I'm guessing we have

to go into here, copy this IB action.

And do play sound

music button. And then

I'm not sure if this has to be down here,

or do I have to copy this one and then

change the path for resource to, I don't

know, blood1, which is our filename for

the blood spatter sound. Sound, but then

this warning sign comes up. I don't know

why.

What if I put, put this into the IB

action, into here?

Would it work? Maybe I have to link

it up first.

Ah, takes so long.

Okay, so you go ViewController and

then IBActions here, and then we just—

what's this? There's like an exclamation

mark. It's not defined on ViewController.

So I want this button to touch up inside.

Don't think it's going to work.

Now I've tried a different, a different

way of doing the sound. On YouTube there's

all these tutorials how to do sound and

they use AV Foundation, but I've tried AV

Foundation and I've done exactly what

they've said on the video and But I can't

get the damn sounds to work. When I click

on the button, the whole game crashes.

It's like it's trying to load the sound,

but it fails. See, it doesn't work.

It crashes. I don't know why.

Why can't I make a second sound?

See, if I go to ViewController.m and I get

rid of this, let's see what happens.

Nope, still crashing. So why is it

crashing? Let's try

and change it to play sound ID so it's the

same as this one. Oh, this is an

IB app. Oh no, no, no. Oh no, I have 2

senders in here. Was that the reason?

Okay, so let's put it all back in like

it was before. Silly me, I had 2.

Oh, what's happened now?

Use of undeclared identifier. Did you mean

blood1? Oh yeah. Okay, see if it works

this time. So we have gun

on this one, the gun sound.

And is it crashing? No, it's not actually

crashing, but it has this warning: failure

to set up sound. Uh, uh, error equals

-50. So why is it coming up with the

error? So if we change this to play sound

Would it play the gunshot when I click on

the sound button? Oh, it does.

Oh no, it's playing blood.

What? The first sound was the

gunshot and now it's playing blood. Why is

it playing blood? That was so strange.

Okay, let's try it again.

Okay, so this should be gunshot.

It's still doing gunshot. So when I

do this one, it's also gunshot,

but then the second one goes blood,

and then it just stays as blood. So

something's going wrong, but we're on the

right path. We need 2 buttons with 2

separate sounds. That's what my goal for

today is. So I finished my,

my I finished most of the game, the main

part of the game,

and I just need to add maybe an

extra type of zombie, like a really fast

one, and I need to change the projectiles.

First, my idea was to do like a sheep,

but you can't really tell that it's a

sheep. It looks like a white puffy cloud

flying down the screen. So I drew a log.

I just need to reassign the image to the

new log. And then I need

to do the high score. I can't get the high

score working either.

Either. Yeah, I don't know, is high score

really important? Do you really care if

you have a high score? I mean, there's

final score, but it resets to 0 after the

game ends. I guess if you really cared

about your high score, you could just

write it down. It's not very professional,

is it? So how

do we get 2 buttons playing 2 separate

sounds? What if I get rid of this gun,

also playing the gun sound?

So maybe what

if I put a boot in? I don't know,

like if sound 1 equals

yes, then play

this one, and then if sound

2 equals yes, then play the

blood one. Okay, so let's set up those

booleans.

Oops, where is it?

Why isn't it capital letters? I need

capital letters. Oh, for God's

sake. Okay,

why aren't you doing what I ask you to?

Okay, there we go. Sound 1.

That was frustrating. And then sound 2.

Go away! Why are you doing red, red

exclamation warning signs?

Okay, let me see. So go back into game.h.

I used to have this friend in Japan called

Adam. When I said H, he just started

laughing. He said it's not H, it's H.

Must be an American thing. I'm sure

English people say H, or maybe it's just

me, I don't know. But to me, H sounds

really stupid. So it should

be under— where do I put

boons? Boudins. It should be on top

of On top of interface game.

All right, should be on top. Okay, I get

it. Ah, you have to be so picky,

don't you? Okay, so we have

2 balls. And what are these warning

signs? So if sound 1 equals yes, so if we

press first button, it will do sound 1

equals yes. So it's switching to yes, and

if it's yes, it'll play that sound. So if

we do the same here, sound 2 equals yes.

Don't know if this is gonna work. I don't

think it will. It's crazy. It's crazy.

It's a crazy idea.

Will it actually run the simulator,

please? I don't know why it just like

freezes sometimes. The simulator doesn't

do anything. Oh no, it's fading. Is it

because of these brackets?

Yeah.

Okay, okay, so first one, gun sound.

Nope, it's crashing now. It's not

playing any sounds.

Okay, that didn't work. I didn't think it

would work anyway. Get rid of

the Boodians. Oh, how do I do it?

I don't know what's going wrong.

Still got curly brackets on the end.

It's still fading.

Okay, just get rid of this.

So any ideas, guys? We have 2 buttons.

What if I get rid of this and put this in

here? I want this one to play the blood

sound, but when it starts playing the

blood sound, the top one plays the blood

No, so I need this piece of code, play

system sound.

If I change it like this,

but what if I, what if I put this bit into

here?

Why did Apple make it so difficult? All I

want to do is make a button play a sound.

They have to have this stupid code which

is so long and complex.

And I tried looking at the official

documentation on Apple's website, and it's

so complex. It's like so technical. So

look, if you want to look up the word then

and you look it up in a dictionary, you

get this whole wall of text technically

explaining what then means. Okay, let's

try. Failure to set up sound.

Oh, what's this? Maybe we need

to change this bottom part to blood 1.

Right,

would it work now?

Gun sound.

Splat sound. Gun sound.

We've done it!

We've done it, guys, guys,

guys, guys, guys! We have 2 buttons. Each

one playing a separate sound.

Splat, gun, splat, gun. Oh,

I'm so happy. I'm so happy I could kiss

you, but I won't because we're on the

internet and such behavior isn't

appropriate. So what did we do? We created

a second button and we created this one.

We don't need those stupid balls, they

were useless. We created a new system

sound ID called blood1. And then we went

into ViewController.m, created the

IBAction for the second button, and we did

this bit which is needed to play the

sound. And we need this bit as well to

tell which sound to play. And we changed

the file name to blood1, which is here,

blood1 down here. And then we

change the sound URL and

play sound ID to the new sound, which is

blood1. So I think

we also need this at the bottom. I'm not

quite sure. Failed.

But if I get rid of all of them from the

viewDidLoad, what happens? Do I need it in

the viewDidLoad? I don't think so. So gun

sound,

blood sound,

gun sound. Oh, that's perfect.

Okay, so the next thing I want to know is

how do I loop it? So if this was music,

how do I keep the music from stopping?

Wouldn't it be audio player?

I don't know.

There's this tutorial I was watching, but

he does it on AV Foundation. And for some

reason I can't get AVFoundation to work.

And he did this code called

audioPlayer.numberOfLoops equals

-1. So I want that. Does that work on

AudioToolbox?

audioPlayer numberOfLoops—

nope, still working. I guess

I have to Google it later because I'm

using Audio Toolbox framework,

not the AVFoundation. I'm not really

quite sure what the difference is between

the two, but most people seem to be using

AVFoundation, which I can't seem to get— I

can't seem to get working for some reason.

16 minutes.

Okay, so I think I'm getting the hang of

It's still kind of strange because watch,

the first time I click it, nothing happens

and it comes up this error: failure to set

up sound. But if I press it a second time,

it works. And then the first time on blood

splatter, it doesn't work, and then the

second time it does work. It's really

I don't know why it fails to set up the

sound at first.

Maybe I need it in the viewDidLoad.

Because in the tutorial I watched, he put

it in the viewDidLoad at the beginning.

Oh, it works now. First,

maybe I need this bit only and put

playBlood1. Or would it work? Would it

work? So first time should play the sound.

Yeah, first time plays the sound. No,

so the first time it's playing the gun

sound for some reason.

But if I copy this bit as well, it comes

up with an error. It says redefinition

of sound URL.

So it's basically saying that I have 2

What is SoundURL? It's an NSURL.

Was that something— oh, that's something

we made. So if I call this something else

like sound2 and change this to sound2,

would it work? I don't really

understand what this code is doing. What

is an nsurl?

Okay, see if it works. So first one should

be gun sound, second one should be blood

sound. Damn it,

it's not working.

Because if we get rid of this, it will

play the blood sound, but the first time

you click it, it won't play. Watch. See,

nothing. You get faded to set up sound.

Then the second time it works.

Ah, it's not easy.

I'm gonna have to figure it out next time,

and I'll let you know when I figured it—

figured it out. And I'll see you next
