It is not used as a parameter for draw, make it a separate assignment. All
subsequently generated random numbers will be identical for future mp runs.
This might me a problem if you want it to affect only a single draw (do
you?), then it would have to be a local assignment. Or you would have to
assign it a new value after this single draw, randomly generated from
another source, maybe passed from TeX. But I'm not that experienced with
mp/context to present you a solution to this problem on the fly. Ah,
however, except putting the randomseed assignment and the commands to be
affected at the very end of your graphic. But if you need something like
this, Hans will surely have a good idea.
For this graphic,
\startreusableMPgraphic{omcirkeld}
randomseed:=2022;
draw fulldiamond xyscaled (OverlayWidth,OverlayHeight)
randomized (30*OverlayLineWidth)
withpen pencircle scaled OverlayLineWidth
withcolor OverlayLineColor ;
path b ; b := boundingbox currentpicture ;
setbounds currentpicture to b enlarged 10pt ;
\stopreusableMPgraphic
should do it.
