Jeong Dal mailto:haksan@me.com 21. Januar 2016 um 15:55 Thanks Hans, Wolfgang, Luigi
The new beta with Luatex 0.88 makes \fieldstacks and \startanimation work. The following example of Wolfgang is now working well.
\def\MyGraphics#1{% \unexpanded\def\MyGraphics#1{% \startMPcode path p,q; p:=fullcircle scaled 72; L:=length p; N:=20; q:=subpath (0,#1/N*L) of p; draw q withcolor red; fill fullcircle scaled 3 shifted point length q of q withcolor blue; setbounds currentpicture to unitsquare shifted (-0.5,-0.5) scaled 75; \stopMPcode} \usemodule[animation] \setupinteraction[state=start]
\starttext \startanimation[menu=yes] {\MyGraphics {5}} {\MyGraphics {10}} {\MyGraphics {15}} {\MyGraphics {20}} \stopanimation
\stoptext
One more question. Is there any convenient way to list \MyGraphics{#1}? I tried \dorecurse, but it just display figures one by one. I also tried lua, but it stops with the error message “unexpected symbol near ‘\'”. \startanimation[menu=yes] \dorecurse{20}{\expanded{\startframe \MyGraphics{\recurselevel} \stopframe}} \stopanimation
