0:00ooh free
0:02tacos I am quite
0:06hungry oh
0:08no
0:10[Music]
0:13T okay okay you might ask what the heck
0:16that was about that was pretty much my
0:18introduction to what we're going to be
0:19talking about in this episode which is
0:21going to be sounds and sound groups and
0:23so in any video game you can think of
0:26not even just Roblox but any video game
0:28sound design is one of the most
0:30important aspects to a video game
0:32because it enhances the gameplay
0:34experience for everybody that's playing
0:36the game like imagine the example that I
0:38just showed you like 30 seconds ago
0:40without any sounds it would probably
0:42sound less cringe sure but but those
0:44sounds are able to amplify the gameplay
0:46experience for everybody that's playing
0:48the game and so that's what I'm going to
0:50be showing you how to do inside of this
0:51episode so with that being said let's
0:53jump straight into the episode all right
0:55let's think about this for a minute now
0:57that we know sounds exist where do we
0:59find these sounds or in this case audio
1:02well there's two places of finding these
1:04sounds and the first one is from the
1:06Roblox website itself in the creators
1:09tab but I'm going to be showing you the
1:10second way of finding these audio and
1:13that is from the toolbox if you don't
1:15remember where the toolboxes there's two
1:17ways of finding it so the first one is
1:20if you go to home there should be this
1:22toolbox button under the insert category
1:24if we click that then we should see a
1:27toolbox popup that shows us a whole
1:29whole bunch of community created
1:31resources that we can Implement straight
1:33into our Roblox game the second place to
1:36find this is by going to view and then
1:38clicking on the toolbox um button that
1:41shows right here I mentioned this
1:43previously when I introduced the toolbox
1:45you should generally not use this
1:47toolbox because there's a lot of
1:48backdoor scripts in a lot of these
1:50Community created assets so I would be
1:53very cautious implementing these inside
1:55of your Roblox game but for the sake of
1:57this tutorial we'll be using it so to
1:59find these audio we have to click on
2:01this drop down that says models and we
2:03should see a tab called audio if we
2:06click that then we should see two
2:08different tabs that show sound effects
2:10and music so in this case what we're
2:13going to do is just go through these
2:15entries and pick out which one seems the
2:18best to us so by each of these we can
2:20click this play button to test out the
2:22audio before inserting it into our game
2:24so let's hit
2:26this okay so this is a simple rain sound
2:29effect let's try the second
2:32one okay so this one sounds like a this
2:36this one sounds like pretty good music
2:38um well this is in the sound effects
2:39category so it doesn't really make sense
2:41uh but yeah this sound effect or music
2:44in this case sounds pretty good so how
2:46do we insert it well we just simply hit
2:48this insert button and this will insert
2:51it straight into our workspace and it
2:54comes in an instance called a sound so
2:57this is pretty much what it looks like
2:59and down here in the properties we can
3:01see that we can preview this sound
3:03effect just by clicking on this play
3:05button and this is to let us know that
3:08the sound is actually working
3:10properly so now it just comes down to
3:12implementing it through our scripts so
3:15there's an important property I want you
3:16to understand first and that is this
3:19property called sound ID and it's pretty
3:21much a string that basically has a URL
3:24of RBX asset ID colon uh 24 dases and
3:29then you have this big number right here
3:31at the end of it this is essentially a
3:33unique ID to this specific audio that we
3:37just pulled out which is this uh song
3:39that we pulled from the audio library so
3:42if we change this number to a different
3:45number that's also an ID for another
3:48sound then it'll change our sound object
3:52to that new sound so for instance let's
3:55take another sound uh just like
3:57something completely random uh let's
3:59insert this one this one is called
4:01nightmare yelling bursts of distorted
4:03something I don't even know what that
4:04says by the end of it but as you can see
4:07with this sound ID the URL is the same
4:10but what's different is the number so
4:12this one is like 912 something something
4:14something 501 this one is 9125 something
4:17something something 017 so these have a
4:20different ID from each other letting you
4:23know that this is the sound for whatever
4:27this sound is on the Roblox website so
4:30that's something I wanted you to know
4:31about there's a bunch of other
4:32properties here like in this playback
4:34category that shows looped playback
4:36speed time position and volume so let me
4:39give you a quick rundown of each of
4:41these so looped basically means that
4:43when the sound finishes when it reaches
4:46the end of the its time length then it's
4:49just simply going to play the sound
4:52again from the beginning so if I have
4:53this selected and I just play this then
4:56by the end it should automatically
4:58restart playback speed is basically how
5:01fast the audio is playing so if if I set
5:04this to two then it should double the
5:07speed of the playback
5:11speed and by default the number is just
5:13one time position is where in the audio
5:16you want to start and finally we have
5:18volume which obviously it's how loud or
5:21how soft the audio is when you play it
5:24so 0.5 is the default but a lot of sound
5:26effects I know developers use is usually
5:29at volume 1 but that really depends on
5:32your preference so that was just a quick
5:33rundown of some of the sound properties
5:36we might use inside of our Roblox games
5:38now let's get to playing these sound
5:39effects inside of our game so on the
5:42right side let's rename our sound to
5:45test music and then let's add in a
5:48script inside of workspace so let's
5:50insert a script and let's first make
5:52reference to our sound so we'll say
5:55local music equals script.
6:00parent. test music and there's basically
6:03four methods or functions that I want to
6:05teach you with sounds and the first
6:07one's going to actually play the sound
6:09so we're going to simply just say music
6:13colon play open parentheses close
6:15parenthesis and that's literally it it's
6:17just one simple line so if I go and hit
6:21test as soon as we join into the game
6:24then the sound should be
6:27playing so there you go as soon as we
6:30joined in the game The Script made the
6:31sound play and it's going to keep on
6:33playing until it reaches the end of the
6:35sound and then it's going to stop unless
6:38we have Loop turned on which in this
6:39case we don't so if at any certain point
6:42we want to pause the music we would just
6:45drop a line down here and we would
6:46simply just say music colon pause open
6:50parentheses close parenthesis and we can
6:52add in a task. weight here for like
6:54about 3 seconds for it to just pause and
6:58when we pause it we can also resume it
6:59too so let's add in another task. we of
7:032 seconds and put in music colon resume
7:07to continue where it left off and then
7:10finally at the end we could just stop it
7:12completely by saying task. weight uh
7:15about maybe 5 seconds and then we'll say
7:18music colon stop so this will just
7:22completely stop the music and it'll make
7:24the time position go back to the
7:26beginning so that we'll wait for the
7:28next time that we call uh music colon
7:31play so now let's test the game so what
7:34should happen is about in about 3
7:36seconds it'll pause the sound and then
7:38it'll resume it and then stop
7:41it yeah so it paused and then it resumed
7:44so now after a little bit it should
7:46completely stop it all right and there
7:49we go so now we've successfully been
7:51able to play our sounds we've been able
7:53to pause it resume it and even stop it
7:55so those are all the methods provided to
7:58us with sounds on Roblox now you might
8:00have questions about the audio that just
8:02played who is it being played to how far
8:06can you hear this sound this is a
8:08concept with Roblox sounds that I'm
8:09going to be calling Global and local
8:13sounds so pretty much what you just
8:15heard was a global sound because we had
8:18a script inside of workspace play the
8:21sound as soon as the game started up so
8:24everybody inside of the game so every
8:26player no matter when they join the game
8:29they will hear the same part of the
8:32sound wherever they are and with
8:34whatever property the sound has so if we
8:38were in the first 30 seconds of the
8:40sound then all players are going to be
8:43hearing that specific part of the sound
8:46if it's at volume two they're going to
8:47hear it at volume two and if it's at
8:49playback speed two then they're also
8:51going to hear that so that's pretty much
8:53what Global sound is but now you might
8:55wonder how do we play a sound for a
8:57specific player this is is actually
8:59relatively easy what we can do is put in
9:02a sound inside of any property that's
9:04only local to the player like starter
9:06GUI starter pack starter player just
9:09insert sounds in there and have a local
9:11script play that sound so let's take
9:15starter GUI for example so I'm going to
9:17take this music and put it inside of
9:19starter GUI and I'm also going to
9:22disable the script since we're not going
9:24to use it anymore let's create a new
9:26local script inside of starter GUI and
9:28let's make reference to our test music
9:31so we're going to say local music equals
9:33script. parent. test music now what
9:37we'll do is we'll just simply say music
9:40colon play just like before now let's go
9:43into the game hit test and hit play see
9:46what happens it's kind of hard to tell
9:47the difference but trust me when I say
9:49that this is that this is being played
9:51on the local player whenever the player
9:54has joined the game for the first time
9:55so meaning in about 30 seconds if
9:58another player joins the game they're
10:00going to be hearing the sound from the
10:02beginning and not where I currently am
10:04with the sound so the sound is pretty
10:06much going to be located inside of our
10:08player GUI and this is where it's going
10:10to be played so this is the most common
10:13place you would see local sounds it
10:15would usually be inside of your player
10:16GUI because if you had like a GUI shop
10:21or any sort of UI interface that plays a
10:23sound whenever you open it up or
10:25interact with it then it's usually going
10:26to be played inside of starter GUI or
10:29just any local sound period it's going
10:31to be played inside of player GUI We Now
10:33understand Global sounds we also Now
10:35understand local sounds but there's also
10:37another type of sound that I would like
10:40to call proximity sounds and these are
10:42basically sounds that can be heard from
10:45a specific part of the game where the
10:48closer you are to that part the louder
10:51the sound is but the farther you wait
10:53the farther away you are from that part
10:55the quieter it gets so I think you've
10:58seen many examples of this in in Roblox
11:01games before so I think you know what
11:02I'm talking about but if I just insert a
11:04part and let's say there was a sound
11:07that was coming out of this part
11:08specifically the closer I walk up to it
11:11the louder it gets but then the farther
11:13away the character goes the quieter the
11:16sound is going to get until it's barely
11:18audible anymore so this is what I call
11:21so this is what I like to call proximity
11:22sounds and that's what we're going to do
11:23for this part so let's find a new sound
11:25let's go to view and toolbox let's just
11:28search up bubble and see what comes
11:32up okay yeah it's a little quiet but I
11:35think it works so let's hit insert oh
11:37yeah and by the way whatever instance
11:39you're selecting inside of the Explorer
11:40whether that would be workspace uh
11:43replicated storage or just a specific
11:45part if you have it selected and you
11:47insert something from the toolbox it'll
11:50automatically set its uh it'll
11:52automatically set its parent to whatever
11:54you selected so I think that's something
11:56very useful to know about okay but let's
11:59rename this sound to something that's
12:01easier to reference so let's just call
12:03this Bubbles and let's insert another
12:06script so let's make reference to our
12:08Sound by saying
12:11local bubbles equals script. parent.
12:15Bubbles and let's just simply play it
12:18bubbles colon play we might also make
12:21the volume a little bit higher too so we
12:22can hear it better so let's say bubbles.
12:25volume equals 2 and let's also make it a
12:27looped sound effect as well so we're
12:29going to say bubbles. looped equals true
12:34all right so now let's go into the game
12:36and see and see our
12:41result all right and as you can see we
12:44can hear the sound coming specifically
12:47from this part and if we walk farther
12:49away from it we're going to hear the
12:51part less and less and so yeah the
12:53farther away we're walking from this
12:54part the less audible this sound is
12:57going to be but the further we walk
12:59walk up close to it then we're going to
13:01be hearing the sound yet again so we're
13:04going to be walking up just a little bit
13:07closer and now we hear the sound again
13:09so this basically works as intended our
13:11proximity sound effect is perfectly
13:14capable we were able to successfully
13:16create the sounds we want to create
13:17inside of our Roblox games and Implement
13:19them but what if let's say we had
13:22multiple different sounds that we wanted
13:24to play back to back and they also had a
13:28whole bunch of different properties that
13:30we wish we could just change within one
13:33sort of instance like let's say volume
13:35what if we wanted the volume to
13:36consistently be one throughout the
13:38entire thing and we want
13:41to and whatever sound we're playing
13:43through this group or category uh we'll
13:46just stop the whole thing entirely and
13:49then play it again once we want it to
13:51play again so one big example I can
13:54think of is m is music in general so if
13:58you have a whole bunch of sounds that
14:00are inside of a music category and let's
14:02say during specific parts of the game
14:04you want to play the music then you can
14:06play the music and if you want to just
14:08completely cut off all the music then
14:10you would do that using a group or if
14:12you have like a toggle option inside of
14:14settings where you want the music to be
14:16completely off then no music is going to
14:19be playing all of this can pretty much
14:21be done using an instance called a sound
14:24group and let me show you what that
14:25looks like so where would we usually so
14:28where would we put the sound group we
14:30would usually put it inside of a new
14:32service called sound service and this
14:35pretty much handles uh all the sounds
14:37that are generally being played inside
14:39of inside of your Roblox game but I've
14:42seen successful games that don't use
14:43sound service so you don't have to use
14:45this but it is but it is quite helpful
14:47because it shows a bunch of properties
14:49that have to do with manipulating
14:51General sounds inside of your game uh
14:54but for the purpose of this episode
14:56we're going to make a new sound group so
14:58let's hit the Plus sign and let's insert
15:01a sound group so this is what the sound
15:03group looks like and we can probably and
15:05we can pretty much just call this music
15:08and this only has one property which is
15:10volume I will get to this version of
15:13volume in a little bit but as of right
15:15now let's add some music inside of sound
15:16Service uh I'm I'm not going to grab
15:19actual music for copyright reasons but
15:21let's just insert a bunch of sounds
15:24inside of here all right I just inserted
15:26a bunch of sounds uh into my music
15:28folder and like I said sound groups
15:30aren't really that special it's
15:32basically just it's basically just a
15:34collection of sounds you can put inside
15:36of your game to which you can have
15:39easier access to specific sounds that
15:41you're looking for and you can modify
15:43them accordingly um this will come more
15:46in handy when we talk about sound
15:48effects but as of right now these are
15:50all basically placed inside of the same
15:51sound group for easy access so let's
15:54create a local script inside of starter
15:56GUI and let's look for our music sound
16:00group so we're first going to access our
16:02sound service so we're going to say
16:04local sound service equals game colon
16:08get service sound service now let's look
16:12for our music sound Group which is local
16:15music equals sound service wait for
16:19Child open parentheses close parentheses
16:22music Here's what we're going to do
16:25we're going to play a random sound or
16:27music from The Sound s group so let's
16:29pick a random number from one to however
16:32many sounds that are inside of the sound
16:34group so let's say local random num
16:37equals math.
16:40random one comma hashtag symbol music
16:45colon get children because we're trying
16:47to re we're trying to fetch a table not
16:50an instance so now let's go down here
16:53and let's actually get that sound so
16:56we're going to say local random
17:00sound sound equals music in hard
17:04brackets we're going to put in random
17:06num and now let's play that random sound
17:08so Random
17:10sound colon play open parentheses close
17:14parentheses okay I made a little typo
17:16here I'm trying to retrieve the music
17:18table not the actual instance when I'm
17:22trying to fetch the sound uh this can be
17:25more readable just by taking get
17:27children and putting it up here when
17:29we're declaring it that way we don't
17:30have to say get children every time so I
17:33think this makes it a little bit more
17:34readable now let's play the game and see
17:35what
17:37happens okay so when we joined in the
17:39game it played the original song uh now
17:42let's try playing it again and see and
17:44see if it changes to something
17:46different okay and now it's playing
17:47something different which is basically
17:50alarm sound
17:53effects okay and now it's playing a
17:54bunch of static sounds so this seems to
17:57work as intended whenever we join the
17:59game the game is going to automatically
18:01pick a sound from the music's group and
18:04just play it I think we pretty much got
18:06it to do what we wanted it to do now
18:08there's something interesting I want you
18:09to look at so if we go back to our sound
18:12group our music group I mentioned that
18:15there's only one property that's called
18:17volume now you might ask what's the
18:19difference between this volume and the
18:21volume that's inside of an individual
18:24sound like this one so if we remember
18:26back to what volume is for an an
18:28individual sound it's basically how loud
18:31or how quiet the sound is when it gets
18:34played so if it's a volume of zero
18:36obviously you're not going to be able to
18:37hear it so the default is 0.5 but you
18:40can also make it higher to let's say one
18:43to even as big as 10 so that's pretty
18:46much self-explanatory but what's sort of
18:48confusing about sound group sounds is
18:51that this volume changes the volume of
18:55every single sound that's inside of the
18:57sound group that part makes sense but
18:59there is something else that trips
19:01people up about this sound about this
19:03volume property this volume does not act
19:07as a Setter for all of these sounds to
19:10to just be whatever this volume is this
19:13acts as a multiplier to set the volume
19:17of whatever each audio is to amplify it
19:21to whatever this sound is so let's say
19:24we had this sound right here that's
19:26volume 0.5 if our multip lier is 0.5
19:30this is effectively saying we should
19:32take this volume and make the volume by
19:35half so 0.5 * 0.5 is 0.25 because a half
19:42of 0.5 is
19:440.25 and let's say we change this volume
19:47to one 0 0.5 also known as the half of 1
19:52is 0.5 so that's what this new volume is
19:55going to be when you play it and for
19:56other sounds it could be different if
19:58this volume is two then the volume of
20:01this is going to be one because half of
20:04two is 1 since we have this volume
20:07multiplier set to 0.5 now if we set this
20:10volume to two it's going to double the
20:13volume of each individual sound so if
20:15this is volume one then the volume of
20:18this is going to be two when we play it
20:20if this is two then the volume is going
20:23to be four and uh this one is going to
20:25be 1 because 0.5 *
20:29two is one so that's a very distinct
20:33feature about sound group volume that I
20:35want you to understand because people do
20:38get tripped up by it so I I want to say
20:40this one more time the sound group
20:42volume is a multiplier of all these
20:46different sounds it's not a Setter for
20:48all of these sounds to have the same
20:51volume as whatever this sound group
20:54volume property is set to and for the
20:57last part of this episode episode I'm
20:59going to do a brief introduction to
21:01sound effects I'm not going to go too
21:03much into detail with the technicalities
21:05maybe I'll do that in a future episode
21:07but basically a sound effect is a sound
21:10modifier to current sounds or music that
21:13you already have inside of your game so
21:16this can be found inside of our sound
21:18groups and it's convenient to have these
21:20in a sound group because we want to
21:22change we want to add a sound effect to
21:25every single sound that's inside of a
21:27sound group so so this is pretty much
21:29what it's going to look like let's hit
21:30the plus sign next to our sound group
21:32music and we can see that Roblox is
21:36suggesting us to add in a whole bunch of
21:38different sound effects so we have
21:40chorus we have Distortion pit shift
21:43revert Reverb Echo and equalizer but
21:47let's say we want to add in a chorus
21:48sound effect let's add that in and it's
21:50going to be dropped into our sound group
21:53alongside our other sounds so if we
21:56click on this we can see that there's a
21:57bunch of Stack here like depth Min
22:00priority rate I'm not going to go over
22:02these but I'm sure the default settings
22:04are good enough as of right now so it's
22:06pretty much as simple as that all we did
22:08was basically add in a sound effect into
22:10our sound group alongside our sounds and
22:13it'll automatically put that sound
22:15effect inside of these sounds when we
22:17play them so let's hit play and see and
22:20listen to our new
22:23sounds so it is kind of hard to notice
22:26but there is a sort of chorus or echoey
22:29sound effect to the sound that's being
22:32played right now let's try a different
22:34sound to see if we can hear it
22:37better so it's it's hardly noticeable
22:40but there is a very slightly echoey
22:42sound effect by the end of the sound
22:45that's being played that's basically a
22:46small introduction to sound effects that
22:48Roblox has provided for us to manipulate
22:51our sounds a little bit so I just think
22:53it's something pretty useful to have
22:54when you're using this alongside sound
22:56groups so that's pretty much going to
22:58sum up sounds sound groups and even
23:01sound effects as well I hope you found
23:02this episode to be helpful this is
23:04definitely going to be used very very
23:06very often I don't think I really need
23:08to say say anymore um sounds it's kind
23:11of just one of those things you need to
23:12have them in your Roblox game so I hope
23:14that when you watch this video and use
23:16this when you're making your Roblox
23:18games you will find this you will find
23:20this tutorial to be helpful to you and
23:22overall I just think that this is a
23:24really nice feature Roblox has added for
23:26us because it gives us easy access to
23:28audio
23:28using their entire audio library to add
23:32these sounds and music and just play
23:34them whenever we want to and I just
23:36think it's a neat feature to have all
23:37right well that's going to be it for
23:38this episode join my Discord server the
23:39link is in the description and I will
23:41see you in the next episode take care
