How to ignore one axis on orientation

I’m working on a spell/magic tool that you can activate then it does some cool stuff creating blocks.

I’m using the following code to create blocks in the direction the HumanoidRootPart is oriented.

local HumanoidRootPart = Character.HumanoidRootPart

for i=1, 15 do
	CreateNewBlock((HumanoidRootPart.CFrame * CFrame.new(7, 0, (-8 * i))).p)
	CreateNewBlock((HumanoidRootPart.CFrame * CFrame.new(-7, 0, (-8 * i))).p)
end

CreateNewBlock is a function which has a parameter for the target position, the CreateNewBlock function does the block instancing, material, etc.

The -8 * i is used to offset blocks from each other and -7 and 7 are used so both lines of blocks are offset from each other.

Now as you may see in the gif I linked above, the HumanoidRootPart was not only oriented on the Y axis, but also on the X and Z axis. This is a problem because you can see the line of blocks eventually going into the ground.

My question is, how do I ignore certain axis using my code and make the line of blocks go straight?

Instead of Root.CFrame, you can try this.

local Pos = Root.Position;
local X, Y, Z = Pos.X, Pos.Y, Pos.Z;
--// now, you can modify any of the above, as you like
--// for example, you can replace Pos.X and Pos.Z with 0 and they will be 0.

local NPos = Vector3.new(X, Y, Z);
local RootCFrame = CFrame.new(NPos);

--// Replace HumanoidRootPart.CFrame with RootCFrame

Fixed it myself here using a perhaps more inefficient way.
Since I already had to raycast downwards to find the underneath part properties, I just raycast down for each block to find it’s Y axis, this will also help for non flat surfaces too.
