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
\dorecurse{20} {\dontleavehmode\ruledhbox{\MyGraphics{#1}}\allowbreak}
\page
\startluacode
for i = 1, 20 do
context.dontleavehmode()
context.MyGraphics(i)
context.allowbreak()
end
\stopluacode
