i alredy know how to do the particle part but not the scripting part

So you could use a simple .Touched event connected to said part (with a debounce) and then either Enable particles or use Particle:Emit(numofparticles)
Here’s an example.

local lastActivate = 0
local cooldown = 2

part.Touched:Connect(function()
   if os.clock() - lastActivate >= cooldown then
      lastActivate = os.clock()
      particles:Emit(100)
   end
end

how would i choose what particle it emits like could i make when and then reference it in the script?

#4

create a variable that points to said particle

like lets say a particle named epicparticles is located in a part named dog in workspace.
you could create a variable that points to it like this.

local particle = game.Workspace.dog.epicparticles
#5

ok let me try this

#6

btw where would i put this script like serverscriptservice or what

#7

you could just put this inside of the model with the part. it would make it easier to reference the part with the particle in it.

local part = script.Parent.Part
local particle = script.Parent.Particle

example of what i mean ^

#8

ok im trying it now also would it be a local script?

#9

it didnt work so a few things
does the particle emiter have to be enabled?
also heres the workspace
script is the script to play the parrticles
workspace

#11

heres the script i put

local part = script.Parent.Part

local particle = script.Parent.Particle

local lastActivate = 0

local cooldown = 2

part.Touched:Connect(function()

if os.clock() - lastActivate >= cooldown then

lastActivate = os.clock()

particle:Emit(100)

end

end

Okay so I simply showed an example of how you would implement this. What you need to do is just move the script so the parent of the script is TouchableModel. Then you need to change variables to match the names of the parts and particles.

local part = script.Parent.Part  wont work because there is nothing named part.
local part = script.Parent.Union -- will work because Union is a valid member of TouchableModel.

local particle = script.Parent.Particle -- wont work because nothing is named part plus its not inside of the model its inside of Union.

local particle = part.ParticleEmitter -- using the correct variable to reach ParticleEmitter.

#13 
local Particle = game:GetService("ServerStorage"):WaitForChild("ParticleEmitter") -- assuming you put the particle emitter in serverstorage
local Part = script.Parent

local Connection = Part.Touched:Connect(function()
    Particle:Clone().Parent == Part
end)
Connection:Disconnect() -- makes sure it only happens once
#14

let me try this would i have to move the particle emmiter to serverstorage?

(edit now i see that i have to put it in the storage

#15

hmm stil not working the error says that line 5 is a incomplete statment exected assignment or function call

#16 

local Particle = game:GetService("ServerStorage"):WaitForChild("ParticleEmitter") -- assuming you put the particle emitter in serverstorage
local Part = script.Parent

local Connection = Part.Touched:Connect(function()
    local ParticleClone = Particle:Clone()
    ParticleClone.Parent = Part
end)
Connection:Disconnect() -- makes sure it only happens once
#17

hmmm stil not working i dont know why

#18

You can listen to when a player has touched the part using TouchedEvent, then simply clone a ParticleEmitter (or create it using instance.new) and parent it to the part.

#19

Have you even attempted to learn scripting on Roblox before undertaking this? Have you tried to script it on your own? The dev forum is not a place to be given scripts by people. It’s to receive help and feedback if something isn’t working.

First off, put a ParticleEmitter inside your part: (make sure it’s not enabled)

(also add a script inside)

In the script paste this:

--//Services
local Players = game:GetService("Players")

--//Variables
local Part = script.Parent
local ParticleEmitter = Part.ParticleEmitter

--//Controls
local debounce = false
local debounce_wait = 0.5

--//Functions
Part.Touched:Connect(function(hit)
	if debounce then
		return
	end
	
	local player = Players:GetPlayerFromCharacter(hit.Parent)
	
	if player then
		debounce = true
		
		ParticleEmitter:Emit(100)
		
		task.delay(debounce_wait, function()
			debounce = false
		end)
	end
end)
