This remote event inserts particles and trails in attachments / bodyparts of the player when they go above 60 speed, but it should also remove them when they go slower than that again. which it doesnt…
it should also start again after stopping when going below, not perm stop.

local player = game.Players.LocalPlayer
local character = player.Character or script.Parent
local humanoid = character.Humanoid
local remoteevent = game.ReplicatedStorage.RemoteEvent
local RemoteIsActive = false
loc

humanoid.Changed(function(property)
	if property == "WalkSpeed" then
		if character.Humanoid.MoveDirection.Magnitude == 60 then
			RemoteIsActive = true
			remoteevent:FireServer()
			end
	end
end)

humanoid.Changed(function(property)
	if property == "WalkSpeed" then
		if character.Humanoid.MoveDirection.Magnitude <= 59 then
			RemoteIsActive = false
			remoteevent:FireServer()
			for i,v in pairs(character:GetChildren()) do
				if v:IsA("Trail") then
					v:Destroy()
				end
			end
			for i,v in pairs(character:GetChildren()) do
				if v:IsA("ParticleEmitter") then
					v:Destroy()
				end
			end
		end
	end
end)

--this remote "stops" the action inside the while loop
remoteevent:Connect(function()
	RemoteIsActive = false 
end)
