How do i turn this into a working aura? cuz i inserted into my aura script it didn't run.

game.Players.PlayerAdded:connect(function(player)
player.CharacterAdded:connect(function(character) 

local Torso = character:WaitForChild("Torso")
b = Instance.new("ParticleEmitter") 
b.Size = NumberSequence.new(2.5)
b.Parent = Torso 
b.LightEmission = 0.7
b.Rate = 50
b.Lifetime = NumberRange.new(0.5)
b.Texture = "http://www.roblox.com/asset/?id=255513949" 

end) 
    end)`

--------------this whole thing is the particle emitter that surrounds the torso, so how do i turn this into local script that can be used in tools?

Hierarchy:

• StarterPack
  • Tool
    • Handle
    • LocalScript

local tool = script.Parent
local p = game.Players.LocalPlayer
local torso = p.Character:WaitForChild("Torso")
local particleName = "ToolParticles"

tool.Equipped:connect(function()
	if torso:FindFirstChild(particleName) then
			local b = Instance.new("ParticleEmitter",torso)
			b.Name = particleName
			b.Size = NumberSequence.new(2,5)
			b.LightEmission = 0.7
			b.Rate = 50
			b.Lifetime = NumberRange.new(1,5)
			b.Texture = "http://www.roblox.com/asset/?id=255513949"
	end
end)

tool.Unequipped:connect(function()
	local particles = torso:FindFirstChild(particleName)
	if  particles then
		particles:Destroy()
	end
end)

If you need it to be explained, comment.

ok so instead of doing that u need to do this put the aura in replicated storage put the script under a local script put into a keybind so u can use it ill post 1 down here type this script local aurafolder = game.ReplicatedStorage.(asset folder name should be here I named mine aura so)

then that's it u just go and put that at the top of ur script also if u have disco I can show u on disco
