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{% \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 ‘\'”. \dorecurse{20} {{\MyGraphics {\recurselevel}} \startluacode for i = 1, 20 do context(“{\\MyGraphics smb://MyGraphics{i}}”) end \stopluacode Thanks again. Best regards, Dalyoung

Hi Hans,

the fieldstack mechanism doesn’t work anymore.

\setupinteraction[state=start]

\starttext \showframe

\definesymbol[frame-1][\tt 1] \definesymbol[frame-2][\tt 2] \definesymbol[frame-3][\tt 3]

\definefieldstack[frame][frame-1,frame-2,frame-3]

\placeontopofeachother {\framed[strut=no,offset=1ex]{\fieldstack[frame]}} {\goto{Play}[Walk{frame}]}

\stoptext

fixed in next engine update
