R6 Barrage Module: A simple module for barrages

Bartokens · February 5, 2024, 2:56am

So a few months ago I was curious about how fighting games like Your Bizzare Adventure achieved a good-looking barrage effect. Originally I had thought it was simple animation tricks, but if you’ve worked with animations on Roblox, you’d know that achieving the sort of hundreds of hands effect is not possible with animations alone. After a bit of research, I discovered bezier curves, and after experimenting with them a bit, I was able to achieve an effect I liked, that mimicked the effect you see in games like YBA:

And now I would like to share it, as I had a hard time figuring it out, and I have noticed quite a bit of people want to achieve this sort of effect. So here it is:

I’ve also created an Uncopylocked place with some added VFX that aren’t present in the model.

Using the module is incredibly simple:

local bm = require(script.BarrageModule)
local distance = 7 --How many studs in front of the player the barrage will reach
local speed = 20 --how slow you want the punch to go. The higher this number is, the slower the punch travels.
local rate =0.015 --delay between punches. uses task.wait() so the minimum value is 0.015
local armCopy = true -- whether or not you want the punches to copy the meshes of the arms. When set to false the arms will be the standard blocky ones.
bm.barragestart(char, distance, speed, rate, armCopy)

And when you want to end it:

bm.barragend(char)

Distance changes the distance of the barrage, and can lead to some entertaining results when set to higher numbers:

Speed is how long it takes for the punch to reach the end. Increasing this too high results in a ludicrous amount of punches:

Rate is the delay in seconds between each punch. Lowering it increases how many punches you have, and increasing it decreases how many punches you have:

And armCopy is whether or not you want the punches to copy the meshes of your arms. When set to true and your character has non blocky arms, it looks like this:

Now if you’re curious as to how it works, it simply just clones both of the player’s arms and makes them travel along 2 different randomized curves, until they reach the specified distance away from the player. It is just two loops that constantly repeat this process for each arm until barragend() is called. And since it clones the players arms, any VFX you put into the players arms will be copied onto the barrage as well.

Now there are a few caveats that should be considered:

This only works with R6, you could probably figure it out with R15 pretty easily though.
This was made more for educational purposes than efficiency or reliability, meaning that performance is not something I thought much of when making this, it was moreso for me to learn and I am now just sharing what I’ve learned.If you want to take what I’ve made here, and vastly improve upon it, then you are free to do so.
I made this at a time when I was still learning a lot of things scripting-wise, and I wrote it in about 3 hours. So if you’re a beginner looking at this wanting to learn, then maybe follow the concepts and not so much the actual code.

And that’s about it. See ya.

you a goat brooo appreciate it

Gidexn · February 5, 2024, 10:35am

Thank you so much for this module!

This is a cool module, I have been trying to figure out how to make barrages for a long time, but I have a suggestion to give

I am using the Roblox Boy arms in my avatar

but It uses the blocky arms for the barrage effect

Is there any chance that custom arm support will come?

the pictures...

The pictures are taken on my @VSCPlays account, like how @bluebxrrybot uses pictures that are taken on his @avodey account

Well look what the cat dragged in! I am currently working on an anime fighting esc game and this would defiantly help with making the 64 attacks I have to make for a single character lol.
I probably wont use it exactly but Ill totally use it as a base and leave you some credit for the help!

E P I C

edit

does it deal damage by default? Just wanted to know if Ill have to change that

Bartokens · February 5, 2024, 7:47pm

No, this is purely visual. If you want it to do damage then you’ll have to add that separately

FroDev1002 · February 5, 2024, 8:02pm

Ok cool thanks for the info! I was using my own way of doing damage to begin with so its good!
Its super cool and cant wait to use it!

Bartokens · February 5, 2024, 10:00pm

I’ve updated the module to support non blocky arms. You can now use the copyArm parameter which copies the meshes of the arms.

Hey I stumbled upon this while lookin for barrage modules and the link doesnt work anymore.

Bartokens · August 8, 2025, 4:20pm

Use this for now:
BarrageModule.rbxm (24.2 KB)
Not sure why but Roblox took down a few of my free models on the marketplace

Shroomer3 · August 10, 2025, 9:36am

thanks a bunch

It has been almost a year, but I’ll take my chances that some will reply.
So I have been currently working on a Jojo Game and I have encountered this bug regarding this module.

The barrage effect works completely as intended in server sided, (which is idiotic of me to do that initially) however when I decided to swap to client sided to handle the barrage effects, the visuals are bugged.

Bugged as in the arms are invisible.
I tried tweaking the speed, rates and etc but doesn’t seem like it did anything, the bug still persists.

Barrage handled by server:

Barrage handled by client:

You can see the arms are gone…

Client sided activation of module:

			local distance = 7
			local speed = 15
			local rate = 0.01 -- delay between punches
			
			
			--local damage = 0.3
			local Stand = player.Character:FindFirstChild("Stand_Model")
			barragemodule.barragestart(Stand, distance, speed, rate, true)

Cloned barrage model in workspace:

The “parts” are the decorative parts on the barraging arm. (The Star Platinum’s arm)

I was hoping and guessing streaming enabled would be the fix or somehow related but it wasn’t either.

I have no clue to what is causing this issue.
The module I used is the exactly same.

I did tweak a little but nothing to affect the barrage visual.

Just incase I’ll include it here too.

local module = {}

Any help would be great, thank you!

EDIT:
I FOUND OUT THE ISSUE THAT IS CAUSING THIS.
I tried removing the humanoid that is created in the model of the barraging arms. This fixed the visuals instantly.
