Re: [NTG-context] Fieldstacks are broken

21 Jan 2016

      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
