How do I make a function run multiple times?

[Unarthadoxx (Lazarus)]

I’ve made a gun script, however I have a setting to add multiple bullets per shot

I am unsure how to use coroutines, so could someone help me with this?

(This probably isn’t the best way to do this, but if someone could tell me if there’s a better way to do this, please do.)

	local function SpawnBullet()
		local Bullet = Instance.new("Part", Folder)
		Bullet.Color = BulletColor
		Bullet.Material = Enum.Material.Neon
		Bullet.CanCollide = false
		Bullet.Massless = true
		Bullet.Size = Vector3.new(0.25,0.25,2.5)
		
		local Spread = CFrame.Angles(math.rad(math.random(MinSpread, MaxSpread)), math.rad(math.random(MinSpread, MaxSpread)), math.rad(math.random(MinSpread, MaxSpread)))

		Bullet.CFrame = CFrame.lookAt(Gun.Barrel.Position, MousePosition)

		Bullet.CFrame = Bullet.CFrame * Spread
		
		local Velocity = Instance.new("BodyVelocity", Bullet)
		Velocity.MaxForce = Vector3.new(math.huge, math.huge, math.huge)
		Velocity.Velocity = Bullet.CFrame.LookVector * BulletSpeed
		
		local OnCooldown = false

		Bullet.Touched:Connect(function(Hit)
			if not Hit:IsDescendantOf(Character) and Hit and Hit.Parent then
				local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
				if OnCooldown == false then
					OnCooldown = true
					
					if Humanoid then
						Humanoid:TakeDamage(Damage)		

					end
					
					Bullet:Destroy()
					
				end
			end
		end)
		
		local BulletSpawn = Bullet.Position
		
	end
	
	local Coroutine = coroutine.create(SpawnBullet)

	for i = 1, BulletsPerShot do
		coroutine.resume(Coroutine)
		
	end

What you’re doing here is resuming an already created coroutine each time. This will not create a new coroutine each time. Instead, you can use task.spawn() each time.

for i = 1, BulletsPerShot do
	task.spawn(SpawnBullet)
end

and of course, you would REMOVE this line:

local Coroutine = coroutine.create(SpawnBullet)

Hope this helps!

Nope, still does the same thing. I have the value set to 9, but only fires a single projectile.

Can I see the updated code? I want to make sure that you implemented it correctly.

You could use the debris service.

local debris = game:GetService("Debris")
local part = Instance.new("Part")
for i = 1, num_bullets do
    debris:AddItem(part, 1)
end

I’ve also tried using

	for i = 1, BulletsPerShot do
		task.spawn(function()
			SpawnBullet()
			
			print("Bullet")
			
		end)
	end

However, it still doesn’t work.
(Only one part in the folder)
(It printed 9 times, though)

I figured out what the problem was.
The bullets were colliding with each other and hitting themselves.
