backfire

[naive sun]

Hello how can I add backfire to the car system please ? Thanks :)

[naive sun]

Or a drift trace

[prime mist]

you could just put a particle emitter at the tail pipe. im not sure when it would backfire but, when it does just set the ParticleEmitter's "Enabled" setting to false and do

ParticleEmitter:Emit(x) 
-- you can remove x for a default of 16, or replace x with the number of particles you want

[naive sun]

Sorry for my English lol

[naive sun]

Yes ik this but how manage this ?

[prime mist]

what do you mean manage?

[naive sun]

Make it working but not all time

[prime mist]

im not a car guy, when does a car backfire? just randomly?

[naive sun]

I think when acceleration

[prime mist]

do you know how to run a function when your car accelerates?

[naive sun]

No

😅

[prime mist]

do you have a acceleration number somewhere?

[naive sun]

Acceleration number ?

[prime mist]

wait so it happens when the car is gaining speed right?

or when its going fast?

[naive sun]

Yes*

I think when it’s going fast

[prime mist]

so you have to check if the speed of the car is above a certain number when its moving

[naive sun]

Ok

Thanks

Ik how to do this
if speed > 110 end
— do the thing
end

If I’m not wrong

[prime mist]

yes but you have to put that in a loop or something that is called every frame with runservice

[naive sun]

Ok but how do this a little bit randomly ?

[prime mist]

you could do this to change the amount of particles randomly

ParticleEmitter:Emit(math.random(4, 32) --you choose the min and max

[naive sun]

Kk thank you so much

[prime mist]

and you could do this so it randomly waits between backfires

task.wait(math.random(.1, .5)) --you choose the min and max

[naive sun]

And how know when the car have a acceleration or deceleration ?

[naive sun]

Thanks you so much :)

[prime mist]

have you taken phyisics or anything with acceleration in school?

[naive sun]

No

Im French and I’m 16 I don’t have learned this

[prime mist]

its ok

roblox might have smth like it

but you need to find ther change in speed

[naive sun]

How ?

[prime mist]

errm

[prime mist]

maybe you could make a varible of the car's speed, then a second later you make another varible of the car's speed, and then you minus the second speed with the first speed to get the acceleration

[naive sun]

Ok i will try thanks

[prime mist]

then you check if the acceleration amount is high enough for the car to backfire

So, here's the code that creates particle emitter with "working backfire"

local Gun = script.Parent
local Config = Gun:FindFirstChild("Config")
local Remote = Gun:FindFirstChild("Remote")
local Plir = game:GetService("Players"):GetPlayerFromCharacter(Gun.Parent)
local IsReload = false

Remote.Fire.OnServerInvoke = function(SendPlir, Hit)
    if SendPlir == Plir then
        return
    end

    local Projectile = Instance.new("Part", workspace.Camera.Projectile)
    Projectile.Size = Vector3.new(1, 1, 1)
    Projectile.Position = Gun.ShootPart.Position
    Projectile.Anchored = true
    Projectile.CanCollide = false
    Projectile.Material = Enum.Material.Neon

    -- Create a particle emitter
    local ParticleEmitter = Instance.new("ParticleEmitter", Projectile)
    ParticleEmitter.Color = ColorSequence.new(Color3.fromRGB(255, 0, 0))
    ParticleEmitter.Lifetime = NumberSequence.new(0.5)
    ParticleEmitter.Size = NumberSequence.new(0.5)
    ParticleEmitter.Rate = 50
    ParticleEmitter.EmitterSize = Vector3.new(0.1, 0.1, 0.1)
    ParticleEmitter.LightEmission = 1

    Projectile.Velocity = (Hit - Gun.ShootPart.Position).Unit * Config.Velocity.Value
end
```lua

This code will create a red particle emitter attached to the projectile, giving it a visual effect during its drive
