I've tried to figure this out many times and I just can't seem to do it. I know that this code below:
part = script.Parent
for i = 1,10,1 do
part.Size = Vector3.new(part.Size.X + 1,part.Size.Y,part.Size.Z)
wait(0.1)
end
-changes the size of the part but it changes in the direction of negative X and positive X, but I just want it to change only on the direction of positive X. How could I do that?

Go here for help http://wiki.roblox.com/index.php?title=API:Class/BasePart/Resize The first parameter is the side, which is 0 - 5, the second part is how many studs\
That didn't really help.
Try using part:Resize(0, 1) or part.Resize(0, 1)
It worked but it's only resizing it by 1. I want it to resize now by 0.2.
Then just write 0.2 instead of 1.....
Ugh so dumb, it only works with whole numbers.
