I'm crazy, or ROBLOX is bugged?

Alright well, I have been tilted on this same error but it doesn’t make sense at all, hopefully, one of you see the fix?

So here is the error: attempt to perform arithmetic (add) on nil and number

Standard error right? Should be easy.

Well here it is.

local position = Vector3.new(start.X + x/2,start.Y,start.Z + z/2)

Now here is the funny part. I print those equations it works fine! and the code works fine, until I do the following:

local position = Vector3.new(start.X + x/2,start.Y,start.Z + z/2)
positions[i][1] = position -- this is table.

Everything works fine until I add it to the table.

Really lost here, not sure if I am tilted and can’t see it, but I have taken breaks and still confused.

#2

what line is the error on, can you show the whole code maybe? one of the variables is probably nil

#3

What is the “i” variable referencing?

#4

local positions = Vector3, not a table.

positions[i][1] wouldn’t work because Vector3[1] isnt possible.

Edit: Nevermind just saw you editted it.

Sorry, that was an issue on my part, in the actual code it doesn’t show that.

i is the index in the for loop

#7 
local positions = {}
	local start = Vector3.new(zone.Position.X - (x/2), zone.Position.Y, zone.Position.Z - (z/2))
	
	
	print(start.X + x/2, start.Z + z/2)
	print(x/2, z/2)
	for i = 1, split_into do
		local position = Vector3.new(start.X + x/2,start.Y,start.Z + z/2)
        positions[i] = {}
		positions[i][1] = position
		if long == x then
			positions[i][2] = Vector3.new(long, 0, 0)
		else
			positions[i][2] = Vector3.new(0, 0, long)
		end
		start = positions[i]
	end

Vector3s are indexed using strings, like “X”, “Y”, or “Z”

#9

You redefine the table and make it blank during every iteration

#10

sorry edited that in, meant to put

positions[i] = {} either way, that isn’t where the error is.

#11

Here, you redefine start as a table and not a Vector3, which is not what your code is expecting

#12

goodness, looks like a i was tilted, thanks a lot, just needed a new set of eyes on the problem!
