How do I make script run through these badges?

[Katrist]

Just use a loop:

for i, battery in Batteries:GetChildren() do
	battery.BasePart:GetPropertyChangedSignal("Color"):Connect(function()
		if workspace.MyCoolPart.Color == Color3.fromRGB(0, 47, 255) then
			return
		end
		
		local allGreen = true

		for i, otherBattery in Batteries:GetChildren() do
			if otherBattery.BasePart.Color ~= ColorGreen then
				allGreen = false
			end
		end

		if allGreen then
			workspace.MyCoolPart.Color = Color3.fromRGB(0, 47, 255)
		end
	end)
end

For some reason, it gives me this error:

This is what the folder looks like under workspace:

I accidentally typed an extra i in GetChildren(), used my edited script.

Wouldn’t I need to use GetDescendants() instead of GetChildren() here?

Because the BasePart is found in a model inside the batteries folder (the BasePart is what will change colors)

[Katrist]

No, just use otherBattery.BasePart. Sorry for forgetting to add stuff in again lol, check my edited script.
