0:00All right, welcome back. Um, today's
0:03video is going to be how to do visual
0:06effects or V effects for the combat. So,
0:10you'll notice that so far all we just
0:13have is a sort of a just a raw
0:17combat, which if you just play the game
0:19right now, you'll see that it's just
0:21really bare bones right now. There's
0:22nothing there's nothing impactful in the
0:25combat.
0:27So, in this video, I'm going to focus on
0:29how to make visual effects for when you
0:31hit things and for blocking and things
0:34like
0:36that. So, the first thing we want to do
0:39is make a local script in here called
0:42client effects, which the reason we want
0:45to make this in starter player is
0:48because we don't want this local script
0:50to refresh every single time the player
0:52dies. Because if we were to put this in
0:54starter character scripts, this client
0:57effect script would re
0:59um would refresh or reset every time the
1:02player responds. So, we'll keep this in
1:04starter play
1:06scripts. Let's just call this client
1:08effects. The comment and we're going to
1:10make a remote event in here
1:13called client effects. Like so.
1:17Now, I know a lot of other videos they
1:21they show you how to do effects on the
1:23server, which what I mean by that is
1:26let's open up our default hit effect.
1:30They tell you, okay, if we want like a
1:32particle, we just clone a particle like
1:36particle clone like so, and we emit or
1:40like clone emit like so. But this is
1:43actually really bad practice because the
1:45server doesn't like having a lot of
1:47strain put on it. So anything that's
1:52not going to be necessary on the server,
1:55we should always do it on the client.
1:58For example, particles or visual
2:01effects. So let's say for our default,
2:06which this is just a raw, you just hit
2:08the character or you hit the target and
2:10they get pushed back. So we can say
2:12replicated storage remotes the client
2:14effects fire all clients like
2:18so and then after that can go over here
2:21and we can actually listen for the fire
2:24client
2:25event. So let's go over here we get
2:29the client
2:32effects and then we can say
2:34remotesclient effects unclan event
2:36connect
2:37function. So you'll see any argument
2:41that you put in here will correspond to
2:44the arguments in
2:46here. Now there's two different fire
2:49clients, right? You have fire all
2:52clients and you have replicate
2:55storage.client fire client which is just
2:57a single specific client. So you see
3:00that there's automatically an argument
3:02here called
3:04player. So in this case you want to
3:07reference to the client you want to fire
3:09to. Let's just say uh attacker and then
3:14after that any variable following this
3:17would correspond to this. So let's say
3:19action, argument
3:22data. It's going to be table and we can
3:24call a
3:25string. Let's press
3:27enter. So this argument, the attacker
3:32argument doesn't correspond to any of
3:33these. it's already
3:35implied. But if we say blah blah blah
3:38and whatever table we want, these two
3:41arguments are going to correspond to the
3:43action and argument data. So I just want
3:46to note make that a note for you. But in
3:48this case, we need to fire all clients,
3:50which doesn't need the player argument
3:53inside of it because you're firing every
3:55single client for the player in the
3:57game. So we can
3:59say for the action we want it to be
4:03default hit effect. So default hit
4:08and then we want to add some arguments
4:09in
4:11here. So we want the client to know who
4:14exactly we're hitting. So we can say uh
4:17target is equal to target hit. So oops
4:22target hit. And then if we want a sort
4:24of like unique default hit effect, we
4:26can also use the weapon use string like
4:32so. Now in here we have to actually
4:37acknowledge these arguments. So we can
4:38say if action equals default hit, which
4:42is
4:43this, then we can get the argument data,
4:46which is the target, weapon used, and
4:47anything else we put in here.
4:51But for Yep. So let's keep it like
4:56that and
4:58then we'll just do it accordingly.
5:01However, I want to note
5:04that let's say you have a lot of client
5:06effects. You don't want to keep on
5:07duplicating it like this and just fill
5:09up your script with thousands of lines.
5:12So this is where modules comes into
5:13play. So like we've been doing
5:16previously like caching the modules,
5:18we're going to do the same for here.
5:20So let's go over here to modules and
5:22let's make a folder called
5:25client and then we can also because this
5:27is only be accessed by the
5:29client. This is going to be sort of like
5:31an organization type of um
5:34purpose and we can say effects or we can
5:38just remove this and say client effects
5:40like so. I'm going to do it this way so
5:43we don't have a lot of nested folders.
5:45And then we're going to make a module
5:46script called default hit.
5:51Okay. And then we want to say return
5:53function and our arguments. So let's say
5:56argument data
5:58any we go.
6:01Now we can go to our client effects and
6:03we can cache these.
6:06Now, I also want to note once again that
6:10the reason we're doing it for starter
6:11player scripts um in relation to to the
6:14modules, if we do it in starter
6:16character, it's going to refresh and
6:18it's going to reach all these effects
6:20and we don't want that. So, we only want
6:23it to cache it once and then do the
6:24effects
6:25accordingly. So, we can say local
6:28cacheed effects like
6:31so. And then we can require all these
6:34modules. So we can say local
6:40modules. And then after that we can go
6:42underscore, module and modules.client
6:45effects children
6:47do. If it's a module
6:49script then cast effects module.name is
6:53require
6:55module. Now we can say if cast effects
7:00or local found effect
7:03cast effects action. And if we found the
7:06effect, then we want to just run the
7:08function like
7:10so. So we can say found effect open
7:13parenthesis. And it just auto fills it
7:15in for you because it's a function.
7:17We're returning a
7:19function. Let's just call this default
7:22hit. And we can say argument data
7:24because that's the type of data that
7:26we're looking for.
7:28Now, I have in I have linked in the
7:30description all the resources you need,
7:32including sounds, things like that. So,
7:35I already put sounds into my replicated
7:37storage, the assets that sounds like
7:39that. But y'all can organize it however
7:41you want. But now you have the effects
7:45right here.
7:48Now we can go over here
7:51to this paste
7:53inside and then or no let's just go over
7:56here and go to assets and
7:59say effects like
8:01so let's name this the core effects
8:04because the core effects is going to
8:06contain like all of
8:08the all the effects that we should have
8:11like hit effect block and things like
8:13that.
8:15So remember that we have the arguments
8:17for target and weapon used. So we can
8:20say local target equals argument
8:22data target local weapon used
8:27equals argument data weapon
8:32used. So we say if target and weapon
8:34used
8:36then so we want to parent these
8:39attachments to the humanoid report. So
8:44we can say local root part equals target
8:47find for child humanoid root part. If
8:50root part then we'll clone this. So
8:54let's get the variables in here. Uh
8:57initiate the
9:00variables local
9:03assets and then we can say local
9:09um effects equals assets.x
9:14And now we can clone these
9:19attachments. So local clone
9:23equals effects docore effects do hit
9:26effect clone clone.parent equals root
9:29part. Now let's say if we want to add
9:32like a different type of hit effect, we
9:36can say if weapon used equals equals
9:37katana also weapon used equals fist.
9:41Then we can clone a head effect
9:43accordingly. For now, we're just going
9:45to use the normal head
9:46effect. Then once you parent it, we can
9:49emit the effects inside.
9:53for underscore comma effect or let's
9:56just do V and clone get descendants to V
10:00is a particle emitter then V
10:02emits and you see that V emit is a
10:06method of particle emitter so it just
10:08emits all of the
10:10um particles inside based on a certain
10:13count. So in here I have an attribute
10:15called emit count which we can say v get
10:18attributes
10:20oops v get attribute emit count like so
10:24and it's going to emit based on the
10:26number in
10:27each and there's also also something
10:30called emit delay. So we can say if v
10:33get
10:34attribute emit delay is greater than
10:38zero then test
10:40delay get attribute delay and then after
10:44that we can say emit
10:47otherwise we can just omit it normally.
10:52Now for debris service
10:55because we want to actually remove the
10:56effects after a certain amount of time.
10:58So, we say debris.
11:00Make sure you're outside of the loop.
11:03And we can say debris, add item, clone,
11:05comma, let's say one and a half seconds.
11:08Give a little bit time for it
11:11to be good for our default hit.
11:16So, if we play the game
11:23and we punch, we have nothing yet. But
11:25if we punch, hit on me. You see that the
11:29effects are emitting like so. And
11:31because we haven't added any effects for
11:33the block yet, doesn't work. But you see
11:36that this is the normal hit effect. But
11:38if he's walking, there's no
11:41effect. But now we also want to
11:44[Music]
11:46add we want to add
11:50sounds. So let's make another module
11:52called
11:54sound. Like
11:56so. Now in here we can get rid of
11:59these and we can go back to here and
12:03fire all clients again. But in this case
12:05we want to call the sound as it
12:07corresponds to this client effect here.
12:10And then we can say sound
12:14name is equal to the hit sound. So, if
12:17you go to
12:18sounds like that, we can open this right
12:23here and we can say
12:25uh let's say
12:27fist do hit dot and whatever the combo
12:32string is. So, we need to actually go
12:33over here to
12:35fist and we need to pass in the combo
12:39string.
12:41So we want to say true screen
12:45number like so and if we get a default
12:48we can add in the combo string number.
12:52So combo string number let's just call
12:54that
12:55number. Now we can say dot dot dot two
13:00string combo string number and we want
13:02to parent it to the target hit humanoid
13:07part like so.
13:10So now that will play sounds,
13:13but we need to actually reference the
13:15sounds in the mouse rule.
13:18So
13:20the fist hit is we're going to use the
13:22same type of thing we did for the
13:25animations when we loaded them, which is
13:27this. So we can just go over here and
13:30then we can just copy that type line of
13:32code
13:34and then we can go to sound
13:38and we want sound
13:39name equal parent equals argument data.
13:45No,
13:46if sound name and parent, then
13:51let's make that should be a string and
13:53this should
13:54be a base part or it's fine. We'll just
13:59keep that empty because we don't know
14:00what it's going to be. But we'll just do
14:03base part question mark because we don't
14:04know if it's actually going to be bass
14:06part. And then we can say local found
14:10sound equals no.
14:15Or we don't even need to do that. Let's
14:17cash all these sounds in first. So local
14:21cached sounds like
14:24so. And then for underscore,
14:27sound in assets sounds get descendants
14:32too. And we can do this. If sound is a
14:35sound
14:37then full name sound get full name and
14:40then cash
14:43sounds.name equal sound like
14:47so
14:49equals cash sound name if found sound
14:53then local clone found sound clone
14:56clone.p parent equals the parent we say
14:59clone
15:01play and then we can say task.lay delay
15:04found time length because we want it to
15:06remove after a certain amount or we can
15:09just say yeah this this will be fine. We
15:12can do test delay or we can do debris
15:14add item but I'm just going to do test
15:17for now.
15:19So clone
15:21destroy like
15:25so. Now we can get out of this
15:28script. Close out of this. Go back to
15:32default. So now we should have a fist
15:36sound. So play the
15:39game. Walk up and we hit him.
15:43It's weird. There's no sound.
15:46Okay, let's see. Let's go over here
15:50to our
15:54sound. Let's say let's do print sound
15:58name,
16:00parent. Um, let's see. Uh, oops. I need
16:05to change this to full name instead of
16:07sound
16:08name. And now if we
16:15play sounds as you can
16:19see like
16:23so. And then now we want to add a swing
16:27sound. So I have a bunch of swing sounds
16:29that I have for y'all.
16:31And similarly, we can go to default and
16:33just clone this line of code and say
16:36fist. Like that.
16:40Or let's not do this because this is in
16:41the default um the default function
16:44which means you already hit the target.
16:47So we want to go to fist and we want to
16:49go to when the hit box starts
16:53like so. So
16:56fist. Two string swing number two screen
16:59number.
17:00You want to parent it to the character
17:03humanity report.
17:06Now if we play the game, you see
17:10that your swing sounds
17:18like so. Let's remove the prints now
17:21since we debug
17:23that. Remove
17:26it. And that's going to be it for the
17:29default effect or the visual effects at
17:32least. Now we want to actually do the
17:35knockback.
17:37So we're going to use something called
17:38body
17:39velocity. So local knockback
17:44velocity body
17:46velocity knockback velocity to max force
17:50equals 44 comma 0a 44. So, the reason we
17:55do this and we set everything else 44
17:59but the Y zero is because we don't want
18:02the knock back to be affecting how the
18:03character moves in the air. We just
18:06wanted to knock them back, not up or
18:08not, anything like that. And now we'll
18:10set the velocity velocity
18:13equals character oops dot attacker human
18:19part C frame. vector
18:22times uh let's say 10 or let's do five
18:27or six and we want to pair
18:30it character equals target hits humanoid
18:35report like so we want to add debris so
18:41it removes the knock back after a
18:43certain amount of
18:45time knockback comma.3 like So,
18:50and we want to make sure that all these
18:52dummies are unanchored as well.
18:56So, we want the humanoid report to be
18:58unanchored.
19:02Like so.
19:04Now, if you play the game, you'll see
19:06that they get knocked
19:18back. Okay, let's make this knock back a
19:21little bit more intense. So, let's say
19:23times 10 and we'll say two like so. Or
19:27we can say
19:2813. And then we can also since we
19:31knocked the car the target back, we want
19:32to push the player forward a little bit
19:34too to make it smoother. So we'll go
19:36over here and we'll say pull
19:41velocity like so. And we want to make
19:44this around
19:4510. We want to parent it to the actual
19:48character or the attacker's human
19:51part. Like
19:57so. Now if we put
20:06again, see he gets pushed back. Uh I'm
20:10going to give him infinite health for
20:11now. So we don't need to worry about him
20:13dying on us. So we just say max health
20:16999 all the way. And then we can say
20:19health all the way to 99 as
20:22well.
20:24So all right. And
20:27then let's go ahead and make this
20:29duration a bit shorter. And we'll that
20:31should be good. Let's make this around
20:3411 or 12 and 8
20:41n. Let's say that this is going to be
20:45our last
20:47hit, which is our block break in this
20:50case. So we can
20:51say add another variable here called
20:54last hit boolean.
20:56There's going to be a boolean
20:57value. We can go to fist
21:02and we can
21:05say or
21:07constant where is it? Our true swing
21:10number. True screen
21:12number= 5 and true or false. So if it's
21:16the last hit then we do true otherwise
21:19it's going to be
21:20false. Now we go to default.
21:24We can say if last
21:28hit then else. So if it's the last hit
21:31then we want to do a really far knock
21:33back. Otherwise we'll do the normal
21:35velocity. So let's go over here and
21:38we'll say make this like
21:4040. Like so.
21:45And then now if you play the game
21:52so that he gets knocked back far on
21:54last.
21:57Let's make him knock back a little bit
21:58further so we can go to default and make
22:00it like 60
22:01instead. And if you play the game,
22:07you will see that he gets knocked back
22:08even
22:11further like
22:13so. Now we've officially finished with
22:16the defaults hit type finally so we can
22:20get out of that script and then we can
22:22go to our block.
22:26Now let's just copy and paste all of the
22:28things that we want here. So we want
22:31these things right here the sound and
22:33yeah. So we can say
22:37that and we also want the combo string
22:40number in here too. Let's go ahead and
22:43copy
22:49this. Let's add these all back into here
22:54like
22:55so. And then now we can go right here
22:59and we can say
23:00fist.blocked like
23:03so.blocked
23:04dot comma string number. So that's fine.
23:07And we can say block
23:08effect like so.
23:14So we can duplicate the default hit and
23:15change this to
23:17blocked. Then over here we can just
23:19clone the blocked like so. And that's
23:22going to be it for the
23:25block. Hit start. So the a common thing
23:28you'll notice when you're scripting
23:29these sort of client effect things is
23:32that it's really sort of just value
23:34changing to an extent because you see
23:37here we just only need to change one
23:39thing and that constitutes the whole
23:42visual portion of the block
23:44effect. Same with default hit. So yeah,
23:48I just wanted yall to note
23:50that. And then we want to also change
23:53this to block effect so we can match it
23:56up with the actual action.
24:00And if we play the game, we should have
24:03a
24:07block. Oh, let's see what happened here.
24:11A ve attribute emit delay.
24:15Ah, I see. Okay. A ve attribute emit
24:18delay and
24:22greater than zero then so if the if the
24:25mid delay is there then we check if it's
24:27greater than zero otherwise we do
24:29nothing so let's do the same thing for
24:32the default hit so it doesn't error as
24:34well
24:37we go
24:45now you see we have the hit effects or
24:49the block effects
24:52Now, we also want to do the block
24:54sounds.
24:57So, we'll see that blocked. And we have
25:01these sounds right here,
25:04like so.
25:07So, we want fist.block dot combo string
25:11number.
25:15Okay, I see. So we want to randomize
25:17these instead of just doing the comma
25:19string number. So we can say local
25:22random
25:23number
25:26random one comma 4 because that's the
25:29amount
25:30here. And then we can just say two
25:32string random number.
25:36So that should be good. Two string
25:38random number. I'm going to target it so
25:41that
25:51There we go. That works. So, we have the
25:54sound. One, two, three,
25:57four. And now, now that's done, we want
26:00to do the actual block break effect.
26:03So, let's go ahead and clone this again.
26:08And we can call this block
26:12break. And let's go into our hit
26:15effects and we can say we can duplicate
26:19or copy and paste these effects
26:22here and then go over here to block
26:25break. So we want to have a sound in
26:27here and it should be called just block
26:30break and then parent it to target hit
26:33and block break like so.
26:37Now we can go to our visual effect
26:40and I have an effect in here for the B
26:44break called dizzy effect. So let's
26:47clone this in here. Now in this case
26:49it's not a value changing. We're
26:50actually scripting something new. So
26:52we'll local clone effects dizzy effect
26:57clone clone parent equals
27:01the
27:02target. And then we can we want to weld
27:05this So we can say local
27:10weld weld part O. We want to weld the
27:14target's
27:15head to this
27:18part. Parent equals clone.
27:23Like so.
27:25Let's make this all work before we
27:27actually clone the dizzy effect.
27:30Now that the world works, we can
27:35have a duration on it. So here we can
27:37say local duration
27:40number argument data
27:44duration. We need to go over here and
27:46also add duration in here too.
27:50Oh wait, we just changed this. Okay,
27:54we'll just rename this to block break
27:55and we'll name this to block effect.
27:56It's
27:57fine. There we go.
28:02Now we have we want to add a duration
28:04value in here. So duration is equal to
28:071.5
28:11like so cuz we want it to match with
28:13this duration that we already listed.
28:17Now we can say test set duration comma
28:20function and we want to make it smoothly
28:23transition out. So instead of destroying
28:25it, we want to actually disable the
28:28effects.
28:30So in clone get children do or get
28:34descendants
28:38if effect is a particle emitter then
28:41effect enable equals false like so and
28:44then we want to destroy it after maybe
28:46like one and a half
28:47seconds. Give it a little bit time for
28:49it to fade out.
28:53So now if we play the
28:55game, you'll see that we have our block
28:58effect or a block break
29:02effect like so.
29:10And it fades away smoothly too. And then
29:14also we want to clone after we finish
29:16the dizzy effect, we want to clone the
29:17actual block effect now. So, we can go
29:20over here and we can go to default
29:25hit and just clone this or copy and
29:28paste this
29:30part. So, we can go in here and we can
29:33make this a different thread. And there
29:35we go. And we can change this to block
29:40break. Now, if we play the game, we
29:43should als we have should have a
29:45combination of the dizzy effect and the
29:47block break effect.
29:52like so.
30:00And now you see him auto blocking after
30:02we finish the combo.
30:05And yeah, that's it for that. And if we
30:08go over here to just a normal hit dummy,
30:13we'll see just a normal hit effect.
30:18So yeah, that's going to be pretty much
30:22it for this episode. So just a brief
30:26wrap-up, what we did today was we
30:30created a client effects
30:33um local script that calls off of a
30:35remote event, which is client event
30:37client effects. And then we cached all
30:40the modules called client effects in
30:42here and we called them whenever the
30:45remote event was fired.
30:48So once again noting the usefulness for
30:50this, we don't need
30:51to have over a thousand line scripts in
30:54here by just duplicating this and this
30:56over again. We just have a single
30:59function or a single line calling the
31:02function and which corresponds to these.
31:06So yeah, that's pretty much going to be
31:08the end of the episode. The next episode
31:10is going to
31:11be on, I believe, movements. It's either
31:15going to be on a movement system, which
31:17is sprinting and dashing,
31:20or adding different weapons like the
31:22katana, a sword, a dagger, and things
31:25like that. So yeah, hope you enjoyed it.
