Hello,

I have a small problem with the Tween() class. I have created my tween for the width of a box to grow and shrink when clicked, the only problem is, the width grows from the right-hand side of the box outwards, but I want the width to grow from each side proportionately.

The first image is what is happening, and the second image is what I want it to do

Please can you help me on this problem, I don’t know where to start.

Thanks for your time,

Blekk.
