Attempt to call table value when randomizing starting position

Help and Feedback Scripting Support
#1

1. What do you want to achieve? Keep it simple and clear!
I want to make system to randomize the starting position of my tween.
2. What is the issue? Include screenshots / videos if possible!
It throws me an error

The most important clue in the error message is the number 20 after the name of your script, which is the line number where the error occurred. There’s no way for us to tell which line that is though, because you might have omitted some lines of code from your own script and whatnot. So please tell us which line that is.

startpos1 = CFrame.new(start.CFrame * CFrame.new(Vector3(0,0,-11)))
This line

#4

should be Vector3.new

there are also another line which you missed

startpos1 = CFrame.new(start.CFrame * CFrame.new(Vector3(0,0,11)))
-- should be
startpos1 = CFrame.new(start.CFrame * CFrame.new(Vector3.new(0,0,11)))

Hmm it throws me a new error

startpos1 = CFrame.new(start.CFrame)
here’s line 18

#7

change that into

start.CFrame

Edit: actually remove the CFrame.new in the marked areas here

		if startpos == 1 then 
			startpos1 = ~CFrame.new~ (start.CFrame * CFrame.new(Vector3(0,0,11)))
		elseif startpos == 2 then
			startpos1 = ~CFrame.new~(start.CFrame)
		else
			startpos1 = ~CFrame.new~(start.CFrame * CFrame.new(Vector3(0,0,-11)))
			spawnliftiem()
		end

@Lielmaster is correct - you’re incorrectly settting the position part of the CFrame as a CFrame, whereas they should be:

	function randomize()
		 local startpos = math.random(1,3)
		if startpos == 1 then 
			startpos1 = start.CFrame * CFrame.new(Vector3(0,0,11))
		elseif startpos == 2 then
			startpos1 = start.CFrame
		else
			startpos1 = start.CFrame * CFrame.new(Vector3(0,0,-11))
			spawnliftiem()
		end
	end

Also, in your randomize function - only your your ‘else’ statement will call the spawnliftiem() function - I think you meant to move it outside of the if logic, so all 3 scenarios can call it correct?

	function randomize()
		 local startpos = math.random(1,3)
		if startpos == 1 then 
			startpos1 = start.CFrame * CFrame.new(Vector3(0,0,11))
		elseif startpos == 2 then
			startpos1 = start.CFrame
		else
			startpos1 = start.CFrame * CFrame.new(Vector3(0,0,-11))
		end
		spawnliftiem() -- move here?
	end

By the way, did you know you can do the same thing above with just one line of code?

startpos1 = start.CFRame * CFrame.new(0, 0, math.random(-1,1) * 11)
-- if the random is -1 == -11, 0 == 0, 1 = 11 :)

Oh I just realized, my bad. Anyways, it works, thanks all.

don’t forget to mark @Lielmaster response as the solution so this topic can be closed. :slight_smile:
