  1. What do you want to achieve?
    I would like my character to move in the centre of the stud and not along a line

  2. What is the issue?

  3. What solutions have you tried so far?
    Roblox forum, youtube

#2

I think you can move your baseplace

#3

My script probably has the wrong calculation


local player = game.Players.LocalPlayer
local character = player.Character or player.CharacterAdded:Wait()
local humanoid = character:FindFirstChildOfClass("Humanoid")
local moveStep = 4
local isMoving = false

humanoid.WalkSpeed = 0

local function moveCharacter(direction)
	if humanoid and not isMoving then
		isMoving = true

		local newPosition = character.PrimaryPart.Position + direction * moveStep

		local roundedPosition = Vector3.new(
			math.floor(newPosition.X / moveStep + 0.5) * moveStep
			newPosition.Y, 
			math.floor(newPosition.Z / moveStep + 0.5) * moveStep
		)

		local currentCFrame = character.PrimaryPart.CFrame
		local rotationOnly = CFrame.new(Vector3.new(), currentCFrame.lookVector)

		character:SetPrimaryPartCFrame(CFrame.new(roundedPosition) * rotationOnly)

		print("New Position: ", newPosition)
		print("Rounded Position: ", roundedPosition)

		wait(0.1)
		isMoving = false
	end
end

local userInputService = game:GetService("UserInputService")

userInputService.InputBegan:Connect(function(input, gameProcessedEvent)
	if gameProcessedEvent then return end

	if not isMoving then
		local moveDirection = Vector3.new(0, 0, 0)

		if input.KeyCode == Enum.KeyCode.W then
			moveDirection = Vector3.new(1, 0, 0) 
		elseif input.KeyCode == Enum.KeyCode.S then
			moveDirection = Vector3.new(-1, 0, 0)
		elseif input.KeyCode == Enum.KeyCode.A then
			moveDirection = Vector3.new(0, 0, -1)
		elseif input.KeyCode == Enum.KeyCode.D then
			moveDirection = Vector3.new(0, 0, 1)
		end

		print("Move Direction: ", moveDirection)

		local targetPosition = character.PrimaryPart.Position + moveDirection * moveStep
		local ray = Ray.new(character.PrimaryPart.Position, (targetPosition - character.PrimaryPart.Position).unit * moveStep)
		local hit, position = workspace:FindPartOnRay(ray, character)

		print("Hit: ", hit)
		print("Position: ", position)

		if not hit or (hit.Position - character.PrimaryPart.Position).magnitude < moveStep then
			moveCharacter(moveDirection)
		end
	end
end)

I think the most simple solution to this problem is to move the spawnLocation to the center of the stud.

#5

I tried to do this then automatically my character teleports to the line

#6

Id say whatever the problem is, it has something to do with the roundedPosition. For testing purposes, try putting everything into their own print() functions and checking the math yourself

#7

Have you tried offsetting the texture?

#8 
math.floor(newPosition.X / moveStep + 0.5)             * moveStep

this is a round-up, but it lands ‘on the line’ because the floor returns integer

so we should also add 0.5 to move it ‘on the stud’, and then multiply by moveStep

(math.floor(newPosition.X / moveStep + 0.5) + 0.5)     * moveStep

the character behaves strangely now after changing to this and walks in the wrong direction

#10

I fixed it with code:

thanks for your help

local roundedPosition = Vector3.new(
(math.floor((newPosition.X - 0.5 * moveStep) / moveStep + 0.5)) * moveStep + 0.5 * moveStep,
newPosition.Y,
(math.floor((newPosition.Z - 0.5 * moveStep) / moveStep + 0.5)) * moveStep + 0.5 * moveStep
)
