Random ParticleEmitter enabling

Help and Feedback Building Support
#1

I’m trying to create a system where parts are randomly placed around the map and ParticleEmitters are randomly enabled every few seconds, but I can’t seem to enable them, as it says I’m indexing Enabled with nil:

local particle = nil

local function getParticle()
	for i, v in pairs(workspace.RandomExplosions:GetDescendants()) do
		if v:IsA("ParticleEmitter") then
			v = particle
		end
	end
	return particle
end

while wait(math.random(1, 5)) do
	getParticle()
	wait(0.1)
	particle.Enabled = true
	wait(0.1)
	particle.Enabled = false
end
#2 
local particle = nil

local function getParticle()
	for i, v in pairs(workspace.RandomExplosions:GetDescendants()) do
		if v:IsA("ParticleEmitter") then
			v = particle
		end
	end
	return particle
end

while wait(math.random(1, 5)) do
	particle = getParticle()
	wait(0.1)
	particle.Enabled = true
	wait(0.1)
	particle.Enabled = false
end

You forgot to call the function to a variable
#3

You wouldn’t need to define particle if you’d returned it in the calling function, which I have done

#4

local function getParticle()
for i, v in pairs(workspace.RandomExplosions:GetDescendants()) do
if v:IsA(“ParticleEmitter”) then
v = particle --This changed to this
particle = v
end
end
return particle
end

#6

That’s great, it works, but it only works for one part now

#7

Try this code:

function setParticle(bool)
	for i, v in pairs(workspace.RandomExplosions:GetDescendants()) do
		if v:IsA("ParticleEmitter") then
			v.Enabled = bool
		end
	end
end

while wait(math.random(1, 5)) do
	wait(0.1)
	setParticle(true)
	wait(0.1)
	setParticle(false)
end
#8

That code activates all of the emitters all at once.

#9

Can you said me what you want that the particles do?

#10

I need the particles to randomly enable between a certain time period

#11 
function setParticles()
	for i, v in pairs(workspace.RandomExplosions:GetDescendants()) do
		if v:IsA("ParticleEmitter") then
            wait(math.random(1, 5))
            v.Enabled = true
            wait(0.1)
            v.Enabled = false
		end
	end
end

while wait() do
	setParticles()
end
