How do you make an object follow your mouse on a grid?
I'm trying to get a part to follow my mouse on a grid, but it just feels... off... It does not feel like I'm doing the grid part correctly. I tried using both math.ceil and math.floor;
01 | local camera = workspace.CurrentCamera; |
02 | local mouse = game.Players.LocalPlayer:GetMouse(); |
03 |
04 | local previewItem = Instance.new("Part"); |
05 | previewItem.Parent = game.Workspace; |
06 | previewItem.Size = Vector3.new(1, 1, 1); |
07 |
08 | mouse.Move:Connect(function() |
09 | local unitRay = camera:ScreenPointToRay(mouse.X, mouse.Y); |
10 | local ray = Ray.new(unitRay.Origin, unitRay.Direction * 500); |
11 |
12 | local part, pos = workspace:FindPartOnRayWithIgnoreList(ray, {game.Players.LocalPlayer.Character, previewItem}); |
13 |
14 | if part then |
15 | previewItem.Position = Vector3.new(math.floor(pos.X / 5) * 5, math.floor(pos.Y / 5) * 5, math.floor(pos.Z / 5) * 5); |
16 | end; |
17 | end); |
What am I doing wrong and how should I be doing it?
It follows my mouse perfectly without the grid code, the grid code is causing the issue.

I'd recommend using something like this:
1 | function round(n) |
2 | return math.floor(n + .5) |
3 | end |
to round a value.
Your script but with the change:
01 | local camera = workspace.CurrentCamera; |
02 | local mouse = game.Players.LocalPlayer:GetMouse(); |
03 |
04 | local previewItem = Instance.new("Part"); |
05 | previewItem.Parent = game.Workspace; |
06 | previewItem.Size = Vector3.new(1, 1, 1); |
07 |
08 | mouse.Move:Connect(function() |
09 | local unitRay = camera:ScreenPointToRay(mouse.X, mouse.Y); |
10 | local ray = Ray.new(unitRay.Origin, unitRay.Direction * 500); |
11 |
12 | local part, pos = workspace:FindPartOnRayWithIgnoreList(ray, {game.Players.LocalPlayer.Character, previewItem}); |
13 |
14 | if part then |
15 | previewItem.Position = Vector3.new(round(pos.X), round(pos.Y), round(pos.Z); |
16 | end; |
17 | end); |

It's much better but it still doesn't quite feel right. Nowaha 459 — 5y

Then i'd suggest removing the division and multiplication part. Vinceberget 1420 — 5y
