I’m trying to put together a build tool for my game, but I am stumped on how I can get the building parts to properly snap to each other. When I try to use any part with an odd number size, it does not properly align with the studs. There is a .5 stud offset.
Pasted below is an idea on how I want my tool to function. I’d like to leave a disclaimer and say that this is a very bare-bones template for a building tool, simply for the sake of getting my point across:
tool = script.Parent
equipped = false
camera = workspace.CurrentCamera
--services
players = game:GetService('Players')
userInputService = game:GetService('UserInputService')
runService = game:GetService('RunService')
player = players.LocalPlayer
function equipTool()
print('Equipped')
equipped = true
--display preview
previewPart = nil
displayPreview = runService.Heartbeat:Connect(function()
if previewPart then previewPart:Destroy() end
previewPart = nil
local mouse2DPosition = userInputService:GetMouseLocation()
local viewportRay = camera:ViewportPointToRay(mouse2DPosition.X, mouse2DPosition.Y)
local mouseToPartRay = workspace:Raycast(viewportRay.Origin, viewportRay.Direction.Unit * 1000)
if mouseToPartRay then
local playerTorso = player.Character:FindFirstChild('Torso')
local humanoid = player.Character:FindFirstChildOfClass('Humanoid')
if playerTorso and humanoid and humanoid.Health > 0 then
local distanceToPlayer = (mouseToPartRay.Position - playerTorso.Position).Magnitude
if distanceToPlayer <= 100 then -- raycast is within proximity
previewPart = Instance.new('Part')
previewPart.Parent = workspace
previewPart.Size = Vector3.new(3,3,3)
previewPart.Anchored = true
previewPart.CanCollide = false
previewPart.CanQuery = false
--round up values and determine offset
local offset = mouseToPartRay.Normal * .5
local roundedX = math.round(mouseToPartRay.Position.X) + (previewPart.Size.X * offset.X)
local roundedY = math.round(mouseToPartRay.Position.Y) + (previewPart.Size.Y * offset.Y)
local roundedZ = math.round(mouseToPartRay.Position.Z) + (previewPart.Size.Z * offset.Z)
previewPart.Position = Vector3.new(roundedX,roundedY,roundedZ)
end
end
end
end)
end
function unequipTool()
print('Unequipped')
if displayPreview then displayPreview:Disconnect() end
displayPreview = nil
if previewPart then previewPart:Destroy() end
previewPart = nil
equipped = false
end
tool.Equipped:Connect(function()
equipTool()
end)
tool.Unequipped:Connect(function()
unequipTool()
end)
This is a local script that’s supposed to go into a tool with an R6 avatar. It works as intended with even size parts, but I can’t manage to align them with other parts (studs parallel to each other) if there is an odd number in play. Forgive me, because I feel like there are dead simple solutions to this, yet they’re not hitting me. Help is appreciated!
