I am trying to script if part touched a another part the script below will run but it doesn’t work.
If you have any idea please help me.

local Signal1 = script.Parent.SignalParts.Red
local Signal2 = script.Parent.SignalParts.Yellow
local Signal3 = script.Parent.SignalParts.Green

Touch.Touched:Connect(function(Hit)
	local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
	if Humanoid then
		Signal1.Material = Enum.Material.Neon
		Signal2.Material = Enum.Material.SmoothPlastic
		Signal3.Material = Enum.Material.SmoothPlastic
		wait(60)
		Signal1.Material = Enum.Material.SmoothPlastic
		Signal2.Material = Enum.Material.Neon
		Signal3.Material = Enum.Material.SmoothPlastic
		wait(30)
		Signal1.Material = Enum.Material.SmoothPlastic
		Signal2.Material = Enum.Material.SmoothPlastic
		Signal3.Material = Enum.Material.Neon
	end
end)

Simply just use a touched event? It will run if anything touches the part?

#3

Okay let me try that. Please wait.

Add debounce?

local deb = false
local Signal1 = script.Parent.SignalParts.Red
local Signal2 = script.Parent.SignalParts.Yellow
local Signal3 = script.Parent.SignalParts.Green

Touch.Touched:Connect(function(Hit)
if not deb then
deb = true
	local Humanoid = Hit.Parent:FindFirstChild("Humanoid")
	if Humanoid then
		Signal1.Material = Enum.Material.Neon
		Signal2.Material = Enum.Material.SmoothPlastic
		Signal3.Material = Enum.Material.SmoothPlastic
		wait(60)
		Signal1.Material = Enum.Material.SmoothPlastic
		Signal2.Material = Enum.Material.Neon
		Signal3.Material = Enum.Material.SmoothPlastic
		wait(30)
		Signal1.Material = Enum.Material.SmoothPlastic
		Signal2.Material = Enum.Material.SmoothPlastic
		Signal3.Material = Enum.Material.Neon
end
deb = false
	end
end)

Np that does not work. I dont know why.

#6

No. That does not work too. Hmm.

#7

I dont understand what you’re trying to do? can you explain?

#8

Okay. So I am currently making the train system and that script is for traffic light. In train down there is a part.
Below is the train scan part.

if the train part touched to traffic scan. The right red will be neon part. And others will be smoothplastic.

That is I want.

Is the train moving from a script? Because if not, touched events don’t fire for anchored parts.

#10

But I don’t want to use RemoveEvent. (I wanna make it 1 script simple.)

#12

That is script inside. And if train part touched the Touch part script will run.

#13

OH wait. REALLY?? It doesntt work for anchored parT?? OH.

#14

How is the train moving, though? A tween? A loop? Is it anchored?

#15

So I should use weld script? or no?

#16

Not anchored. But I dont know how. My friend made original drive system. Let me see.

#17

However you want to do it, just make sure the .Touched event is actually firing.

Can you do a bit changes? I don’t know these types of script. I can only do beginner script. Also, I am Japanese soo…

#19

I wouldn’t use a touched event. That’s really error prone, because if the part somehow gets destroyed, the system won’t work. I would check if it surpasses a certain threshold, like if the train’s x value is greater than a certain number.

They do fire when anchored.
