Same thing like i said. (scroll up or see)

Hmm… It did the same thing, worse, the ground too.

Edit: This is a very challenging task. Thanks for helping me. Try doing if statements?

#43

Yeah, it’s hard. It’s more of a trial and error mathematical thing.

This might do something:

local player = game.Players.LocalPlayer

local partFolder = Instance.new("Folder") -- folders are better
partFolder.Name = "ModelParts"
partFolder.Parent = workspace

local playerBuild = Instance.new("Folder")
playerBuild.Parent = workspace
playerBuild.Name = player.Name .. " Space"

local moveModel = Instance.new("Model")
moveModel.Parent = partFolder

local part = Instance.new("Part") -- turned into a model just for you, it works significantly better
part.Parent = moveModel
part.Size = Vector3.new(3, 3, 3)
part.Name = player.Name .. " Part"
part.Anchored = true

moveModel.PrimaryPart = part

local mouse = player:GetMouse()
mouse.TargetFilter = moveModel

-- using this function because if i do 0 * n it will turn the vector to 0 allowing me to eliminate the vectors that don't multiply based on the surfaceid and then the ones that equal one will work.
function vectorMultiply(v1, v2)
    return Vector3.new(v1.X * v2.X, v1.Y * v2.Y, v1.Z * v2.Z)
end

function getVectorThingy(normal)
    local largestVector, vectorValue = "X", 0
    for name, value in pairs({X = normal.X, Y = normal.Y, Z = normal.Z}) do
        if vectorValue < value then
           largestVector, vectorValue = name, value
        end
    end
    return largestVector
end

function placeAtMouse(dt) -- egomoose's solution
    if (mouse.Target) then
        -- where we cast our ray from (shifted slightly up so the ray will hit the surface we're hovering)
 
       -- cast our ray and get our normal, which is a unit vector
        local ray = Ray.new(mouse.Origin.p, mouse.Hit.p)
        local hit, pos, normal = workspace:FindPartOnRay(ray, moveModel)
 
        -- CFrame the model
        moveModel:SetPrimaryPartCFrame(
            CFrame.new(mouse.Hit.p + (moveModel:GetExtentsSize()[getVectorThingy(normal)]) -- using this function because vector math doesn't work like that
        )
    end
end
 
-- update every frame
game:GetService("RunService").RenderStepped:connect(placeAtMouse)

It kind of is. Also, you kinda made an error at this line:

largestVector, vectorValue = name
#45

Fixed!

30 characters

#46

Line 50. This is kinda funny. Well, pure pressure I guess.

#47

What’s on line 50? I can’t tell.

#48

CFrame.new(mouse.Hit.p + (moveModel:GetExtentsSize()[getVectorThingy(normal)])) – using this function because vector math doesn’t work like that

#49

nevermind fixed again!

aaaaa

#50

I feel bad for you currently, but heres the error:

 22:02:54.560 - Players.Enchanted_Tix.Backpack.BuildingTool.ToolScript:50: bad argument #2 to '?' (Vector3 expected, got number)
#51

AAAAAAAAAAAAAAAA
Should finally be fixed…

I know how much pain you’re going through. Lets do this tomorrow. (it was an oof like last time)

#53

It’s not that bad, but I’m honestly just determined to do this.

#54

Alright. Give it all you got! (Nah actually take some rest first then do it)

Doing it again, here you go.

    return Vector3.new(v1.X * v2.X, v1.Y * v2.Y, v1.Z * v2.Z)
end

function getVectorThingy(normal)
    local largestVector, vectorValue = "X", 0
    for name, value in pairs({X = normal.X, Y = normal.Y, Z = normal.Z}) do
        if vectorValue < value then

        end
    end
    return largestVector

Ahh… Still the same. Oof. I honestly give up.

#57

Moby this is going to be a good idea, but try using velocity’s because it is more easier.

#58

Velocity won’t work like that unfortunately.

#59

Oh… try… adding more values? For example, CFrame.new(0,0+2,0)

#60

What I need to do, is I need to figure out how to add the axis of which the surface is touching.

So basically, if it’s on top, you add the size of of the Y.

#61

@Enchanted_Tix Mind showing me what is happening?
