How to make iTween.MoveTo path's corner as angulate?

So I am using iTween.MoveTo function,

It moves object like 'A' movement of attached image file.

But I want move object like 'B' movement.

How can I ?

Thanks.

 

I`m not familiar with iTween, but have used DoTween and as a guess I would say that you need to change the path type from catmullrom to linear.
