3D Walking/Running Particles don't stop even when the Player isn't moving

The title says it all. But the Tween also doesn’t resize the part.

Here’s my code.

--//Variables//--
local TweenService = game:GetService("TweenService")
local RunService = game:GetService("RunService")
local Players = game:GetService("Players")
local Player = Players.LocalPlayer
local Character = Player.Character or Player.CharacterAdded:Wait()
local Root = Character:WaitForChild("HumanoidRootPart")
local Humanoid = Character:WaitForChild("Humanoid")
local LeftFoot = Character:WaitForChild("LeftFoot")
local RightFoot = Character:WaitForChild("RightFoot")
local Footstep = Root:WaitForChild("SteppingSound", 30)
----------------------------------------------------
--//Function//--
function onHumanoidRunning(Speed)
	if Speed > 6 then
		Footstep.Playing = true
		local DustPart1 = Instance.new("Part", LeftFoot)
		DustPart1.Name = "DP1"
		DustPart1.Size = Vector3.new(.75, .5, .75)
		DustPart1.Position = LeftFoot.Position
		DustPart1.BrickColor = BrickColor.new(255, 255, 255)
		DustPart1.Anchored = true
		----------------------------------------------------
		local DustPart2 = Instance.new("Part", RightFoot)
		DustPart1.Name = "DP2"
		DustPart2.Size = Vector3.new(.75, .5, .75)
		DustPart2.Position = RightFoot.Position
		DustPart2.BrickColor = BrickColor.new(255, 255, 255)
		DustPart2.Anchored = true
		----------------------------------------------------
		local TweenInform = TweenInfo.new(0.5, Enum.EasingStyle.Linear, Enum.EasingDirection.In)
		local TweenSize1 = TweenService:Create(DustPart1, TweenInform, {Size = Vector3.new(1.25, .75, 1.25), Transparency = 1})
		local TweenSize2 = TweenService:Create(DustPart2, TweenInform, {Size = Vector3.new(1.25, .75, 1.25), Transparency = 1})
		TweenSize1:Play()
		TweenSize2:Play()
		task.wait(0.5)
		DustPart1:Destroy()
		DustPart2:Destroy()
	else
		Footstep.Playing = false
		local DustPart1 = LeftFoot:WaitForChild("DP1")
		local DustPart2 = LeftFoot:WaitForChild("DP2")
		DustPart1:Destroy()
		DustPart2:Destroy()
	end
end
function onHumanoidNotRunning()
	Footstep.Playing = false
end
--//Connections//--
Humanoid.Running:Connect(onHumanoidRunning)
Humanoid.Jumping:Connect(onHumanoidNotRunning)
Humanoid.FreeFalling:Connect(onHumanoidNotRunning)
Humanoid.Swimming:Connect(onHumanoidNotRunning)

Uhhh… Maybe you should also make it so that the DustParts also get destroyed when the “onHumanoidNotRunning()” function plays?

[Birdoman7798 (Birdo_Dev)]

Oh yeah forgot about that thanks but how do i make there be more dust clouds that appear?

[Bubblegumboy29 (Dizazter)]

I mean, you could just add another DustPart instance that appears somewhere else near the player’s legs or something.

Why not place a Particle emitter at an Attachment you place slightly under the ground’s surface?
The effect’s size can be a numbersequence that you can ‘animate’ to make it size properly which would allow you to make it appear to puff up and then settle back down.

[Birdoman7798 (Birdo_Dev)]

Because if you’re playing with low graphics level then you won’t be able to see the particle that much and i don’t like that.
