thanks for any help.

You need to offset the grid texture, the grid texture is offset by 2 studs for some reason.

#3

Its hard to explane this but with the preview block the mouse is meant to always be in the middle of it but for some reason its always on the outside of it.

Do you know how I can fix this?

#4

Can you send me a video showing the problem please? Because I really don’t understand. Also, if devforum says the size is too big to upload, use this Video Resolution Changer.

#5

Its not the best of videos I dont have a good screen recorder.

As you can see the mouse is never in the middle of the block I dont know how to fix it do you know how?

Also sorry you have to download it.

#6

Use OBS (open broadcast software).

What are the Block and Wedge variables? From what I remember, BaseParts don’t have a MouseButton1Click event.

#7

Each part is a model inside it has a MainPart and a block depending on what type of block it is the block is the part so for the wedge model the Block is a wedge part.

And the MouseButton1Click is the TextButtons for each block.

My issue is that the plaement block isnt in the middle of the mouse.

Also sorry you have to download the video.

Maybe try math.round() instead.

local y = math.round(mouse.Hit.Position.Y / 2) * 2 + 1.75
local x = math.round(mouse.Hit.Position.X / 2) * 2
local z = math.round(mouse.Hit.Position.Z / 2) * 2
