How to fix float points with placement system

Help and Feedback Scripting Support
#1

I need to fix float points issues with CFrames, as it’s meaning blocks are janky when placed, and also for data saving purposes (I don’t wanna save a dozen random numbers, when all I need is a single number)

I tried to create this function, but I get Invalid number of arguments: 4 on FixedCFrame, and I also worry that this would break my slabs. Every block is 3x3x3, but slabs are 3x1.5x3, and fear it could break their placement. Either way though, this doesn’t work. I need all numbers of the CFrame to be like this too, as when I rotate parts, their lookvectors and what not also go off

function Helpers.FloatFix(cFrame)
	local Position = Vector3.new(
		math.floor(cFrame.Position.X),
		math.floor(cFrame.Position.Y),
		math.floor(cFrame.Position.Z)
	)
	
	local LookVector = Vector3.new(
		math.floor(cFrame.LookVector.X),
		math.floor(cFrame.LookVector.Y),
		math.floor(cFrame.LookVector.Z)
	)
	
	local RightVector = Vector3.new(
		math.floor(cFrame.RightVector.X),
		math.floor(cFrame.RightVector.Y),
		math.floor(cFrame.RightVector.Z)
	)
	
	local UpVector = Vector3.new(
		math.floor(cFrame.UpVector.X),
		math.floor(cFrame.UpVector.Y),
		math.floor(cFrame.UpVector.Z)
	)
	
	local FixedCFrame = CFrame.new(
		Position,
		LookVector,
		RightVector,
		UpVector
	)
	
	return FixedCFrame
end

print("New", NewCFrame)
local FixedCFrame = Helpers.FloatFix(NewCFrame)
self.CurrentBlock:PivotTo(FixedCFrame)

there is probably some clever math way, and if there is please reply but you could try this

local function fixFloatError(x)
  return tonumber(string.split(tostring(x))[1])
end
#3

I’m not sure if this works in lua, but you can divide any number by one and it should fix floating point.

#4

It does work, but not all the time. It depends how long the number is.

Instead of setpivot, why not just setting the CFrame? If its a model, make a primary part and do :SetPrimaryPartCFrame

#6

Because it is a model. SetPrimaryPartCFrame is deprecated, in favor of PivotTo()

#7

Wait, i had no idea setprimarypartcframe is deprecated
