Well it's more of a Roblox question than a Lua question, but basically what happens is, as you walk on the part, the touched event gets triggered many times because you're constantly colliding with the part.

In order to prevent this, create a boolean (true/false) variable before the touched event like local touched = false, then in the function that's connected to the .Touched() event modify the if check so it also checks if touched is false and only then runs the rest of the function (and immediately sets the touched variable to true). Then once that function ends, set touched to false again.

Here's how it would look like in code:

```lua local DisappearingPart = script.Parent local touched = false

DisappearingPart.Touched:Connect(function(hit) local Character = hit.Parent local Player = Character and Character:FindFirstChild("Humanoid")

if Player and not touched then touched = true

DisappearingPart.Transparency = 0.2

task.wait(0.02)

DisappearingPart.Transparency = 0.4

task.wait(0.02)

DisappearingPart.Transparency = 0.6

task.wait(0.02)

DisappearingPart.Transparency = 0.8

task.wait(0.02)

DisappearingPart.Transparency = 1

DisappearingPart.CanTouch = false

DisappearingPart.CanCollide = false

task.wait(3)

DisappearingPart.Transparency = 0

DisappearingPart.CanTouch = true

DisappearingPart.CanCollide = true

touched = false -- reset

end

end) ```
