Dear Aditya,
Thank you for your code and an explanation.
Let's assume that the last MPpage was a \startuseMPgraphic{boxes} .... \stopuseMPgraphic. Suppose I wanted to use these pictures in a presentation. On the first slide, I can use
\useMPgraphic[stacking=0]{boxes}
to show the three boxes, and on the next slide, I can use
\useMPgraphic[stacking={-1,0}]{boxes}
I tried to reproduce your example using \startuseMPgraphic{boxes} … \stopuseMPgraphic, and useMPgraphic[stacking=0]{boxes} . A modified one of your code is below. There is no error message but no output at all. Would you please tell me what is wrong in here?
[...] \startuseMPgraphic[offset=2mm]{boxes} [...]
You cannot use [offset=2mm] here. Just use \startuseMPgraphic{boxes}. Aditya
