Triangle Module Error

Help and Feedback Scripting Support
1

Basically I’m new to roblox game developing and am currently following some tutorials, one of them including a bloxburg like building system.

The current problem I’m experiencing is “Module code did not return exactly to one value”, which currently breaks one of the other scripts which is currently fine to my knowledge.

If you haven’t noticed this is my first post on here, I’m very new and I would like some help, I have tried searching for solutions, in which case all failed. So I’m resorting to the devforum for some help. :slight_smile:

Here is the module I’m working with

local Triangle do
	local v3 = Vector3.new
	local cf = CFrame.new
	local abs = math.abs
	local cross = v3().Cross
	local dot = v3().Dot
	local clone = game.Clone

	local ref = Instance.new('WedgePart') do
		ref.Color         = Color3.fromRGB(200, 200, 200)
		ref.Material      = Enum.Material.SmoothPlastic
		ref.Reflectance   = 0
		ref.Transparency  = 0
		ref.Name          = ""
		ref.Anchored      = true
		ref.CanCollide    = false
		ref.CFrame        = cf()
		ref.Size          = v3(0.25, 0.25, 0.25)
		ref.BottomSurface = Enum.SurfaceType.Smooth
		ref.TopSurface    = Enum.SurfaceType.Smooth
	end

	local function fromAxes(p, x, y, z)
		return cf(
			p.x, p.y, p.z,
			x.x, y.x, z.x,
			x.y, y.y, z.y,
			x.z, y.z, z.z
		)
	end

	function Triangle(a, b, c, parent, wb, wc, N)
		local ab, ac, bc = b - a, c - a, c - b
		local abl, acl, bcl = ab.magnitude, ac.magnitude, bc.magnitude
		if abl > bcl and abl > acl then
			c, a = a, c
		elseif acl > bcl and acl > abl then
			a, b = b, a
		end
		ab, ac, bc = b - a, c - a, c - b
		local out = cross(ac, ab).unit
		wb = wb or clone(ref)
		wc = wc or clone(ref)
		local biDir = cross(bc, out).unit
		local biLen = abs(dot(ab, biDir))
		local norm = bc.magnitude
		wb.Size = v3(0, abs(dot(ab, bc))/norm, biLen)
		wc.Size = v3(0, biLen, abs(dot(ac, bc))/norm)
		bc = -bc.unit
		wb.CFrame = fromAxes((a + b)/2, -out, bc, -biDir)
		wc.CFrame = fromAxes((a + c)/2, -out, biDir, bc)
		local G = Instance.new("Model", parent)
		G.Name = "Floor" .. N
		wb.Parent = G
		wc.Parent = G
		return wb, wc
	end
end

so thereis a problem, that is not how a module script is supposed to look like

local RenameMe = {}

local Triangle do
	local v3 = Vector3.new
	local cf = CFrame.new
	local abs = math.abs
	local cross = v3().Cross
	local dot = v3().Dot
	local clone = game.Clone

	local ref = Instance.new('WedgePart') do
		ref.Color         = Color3.fromRGB(200, 200, 200)
		ref.Material      = Enum.Material.SmoothPlastic
		ref.Reflectance   = 0
		ref.Transparency  = 0
		ref.Name          = ""
		ref.Anchored      = true
		ref.CanCollide    = false
		ref.CFrame        = cf()
		ref.Size          = v3(0.25, 0.25, 0.25)
		ref.BottomSurface = Enum.SurfaceType.Smooth
		ref.TopSurface    = Enum.SurfaceType.Smooth
	end

local function fromAxes(p, x, y, z)
    return cf(
		p.x, p.y, p.z,
		x.x, y.x, z.x,
		x.y, y.y, z.y,
		x.z, y.z, z.z
		)
end

function RenameMe.Triangle(a, b, c, parent, wb, wc, N)
		local ab, ac, bc = b - a, c - a, c - b
		local abl, acl, bcl = ab.magnitude, ac.magnitude, bc.magnitude
		if abl > bcl and abl > acl then
			c, a = a, c
		elseif acl > bcl and acl > abl then
			a, b = b, a
		end
		ab, ac, bc = b - a, c - a, c - b
		local out = cross(ac, ab).unit
		wb = wb or clone(ref)
		wc = wc or clone(ref)
		local biDir = cross(bc, out).unit
		local biLen = abs(dot(ab, biDir))
		local norm = bc.magnitude
		wb.Size = v3(0, abs(dot(ab, bc))/norm, biLen)
		wc.Size = v3(0, biLen, abs(dot(ac, bc))/norm)
		bc = -bc.unit
		wb.CFrame = fromAxes((a + b)/2, -out, bc, -biDir)
		wc.CFrame = fromAxes((a + c)/2, -out, biDir, bc)
		local G = Instance.new("Model", parent)
		G.Name = "Floor" .. N
		wb.Parent = G
		wc.Parent = G
		return wb, wc
	end
end
        
        -- ModuleScripts must return exactly one value
return RenameMe -- rename both renames to whatever you want to call the functions with

you may also want to remember that all the local functions and values can only be called by this script and not a script getting the module
