Block placement system only 'stacks' on the Positive Axis

Hello, I’ll keep this short, I’m trying to make a simple block placement system like the one found in “Build a Boat for Treasure.”

My problem is that the blocks only ‘stack’ on one face once they’re placed.


This is the grid snapping code snippet.

local function Snap()
	PosX = math.floor(mouse.Hit.X / GridSize + SelectedBlock.Size.X/4) * GridSize
	PosY = math.floor(mouse.Hit.Y  + ghostpart.Size.Y/2)
	PosZ = math.floor(mouse.Hit.Z  / GridSize + SelectedBlock.Size.Z/4) * GridSize
end

I’ve never used math.floor before, and maybe I’m just missing something really simple! Thanks for your time, have a great day!

You need to use ray casting and using CFrame.new(hitpos,hitPos + normal).p
