How Do I Make A Part Change The Baseplate To Specific Colors?

I cant copy and paste my code here rn, because I am on my phone, but how would I make it so that when my character touches a block (Part) it turns the BasePlate into either Purple, Blue, or Black..?

I tried doing

local base = game.Workspace.Baseplate local part = game.Workspace.Part

part.Touched:Connect(function(hit) base.BrickColor = BrickColor.Black() if base.BrickColor = BrickColor.Black() then base.BrickColor = BrickColor.Purple() if base.BrickColor = BrickColor.Purple() then base.BrickColor = BrickColor.Blue() if base.BrickColor = BrickColor.Blue() then base.BrickColor = BrickColor.Black() end end end end

P.S. I just typed this from my phone just now so it might be incorrect, also please dont judge my coding skills. I just started coding 3 days ago..

That's great that you started coding 3 days ago! Let's reformat your program so it'll be easier for us to read. Add that structuree.

--So this is what it looks like. I will mark the parts where your script will error.

local base = game.Workspace.Baseplate
local part = game.Workspace.Part

part.Touched:Connect(function(hit)
	base.BrickColor = BrickColor.Black()
	if base.BrickColor = BrickColor.Black() then	-- right here*
		base.BrickColor = BrickColor.Purple()
		if base.BrickColor = BrickColor.Purple() then -- right here*
			base.BrickColor = BrickColor.Blue()
			if base.BrickColor = BrickColor.Blue() then -- right here *
				base.BrickColor = BrickColor.Black()
			end
		end
	end
end		-- right here**

-- *  you used = instead of ==
-- ** you did not close your event using ")"

1. "=" is the assignment operator.

2. Once you open "(" anything with a parenthesis, you must close ")" it, especially when using the Connect method.

Let's get down to analyzing your code. If all is good and dandy, then the following code is errorless.

local base = game.Workspace.Baseplate
local part = game.Workspace.Part

part.Touched:Connect(function(hit)
	base.BrickColor = BrickColor.Black()
	if base.BrickColor == BrickColor.Black() then
		base.BrickColor = BrickColor.Purple()
		if base.BrickColor == BrickColor.Purple() then
			base.BrickColor = BrickColor.Blue()
			if base.BrickColor == BrickColor.Blue() then
				base.BrickColor = BrickColor.Black()
			end
		end
	end
end)

-- [[
Summary of the code. 
Once "part" is touched,
set "base" to Black.
if "base's" color is Black, then change it to Purple.
	if it's color is Purple, then change it to Blue.
		if it's color is Blue, then change it back to Black.
]]

Problem here is, you'll never see the program alternate colors because you made it go through all the colors.

1. thing touches part.
2. base is black.
3. first "if" statement: is it black? change to purple.
4. changed to purple.
5. second "if": is it purple? change to blue.
6. changed to blue.
7. third "if": is it blue? change to black.
8. back to square one.

Let's prevent that by changing the structure of your "if" statements and relocate line 5.

TL;DR

My suggestion: Don't nest your "ifs". Separate it into compound "if"/"elseif"/"else" statements.

local base = game.Workspace.Baseplate
local part = game.Workspace.Part
base.BrickColor = BrickColor.Black()

part.Touched:Connect(function(hit)
	if base.BrickColor == BrickColor.Black() then
		base.BrickColor = BrickColor.Purple()
	elseif base.BrickColor == BrickColor.Purple() then
		base.BrickColor = BrickColor.Blue()
	elseif base.BrickColor == BrickColor.Blue() then
		base.BrickColor = BrickColor.Black()
	end
end)
