Touched a brick?

When I touch the part the part moves up so thats why I made a position.

x = script.Parent

x.Touched:connect(function()
	
	x.Size = x.Size + Vector3.new(1,1,1)
	x.Position.Vector3.new = -8, -1, -3 --Once it grows when you touch it, the part moves up so thats why I put this line there. So it can go back to its position.
end)

Whoa whoa whoa. This is wrong. Too wrong. The wiki. Readd the wiki!!!!

If you reference the wiki, you would've found this

workspace.Part.Position = Vector3.new(0, 50, 0)

So, for your part, we would do this...

x.Position = Vector3.new(-8, -1, -3)

But this shouldn't work. Why? Position is like the size you did. it offsets the position if it collides with a part. So we will have to use CFrame, that allows parts to collide with other parts and not be offsetted.

x.CFrame = CFrame.new(-8, -1, -3)
