Hi Mikael,

with the solution provided by you, I could work on my graphic which grows from 
page to page. So far I have already 28 pages. Now I would like to go back to 
the summed graphic of p1 to p21 and add the coming p29, p30 etc. to only that 
(that means contents of p22 to p28 should not be visible on pages 29 and 
forward).
I don't bother you with my code which is too long. Let's use the mwe provided 
by you (I added it here for convenience), where we have 3 pages. How can I have 
the content of p2 not be added on page 3 and forward?
\startuseMPgraphic{base}
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);

p1:=image(
label("Word 1", z1);
);

p2:=image(
label("Mot 2", z2);
);

p3:=image(
label("Parola 3", z3);
);

\stopuseMPgraphic
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
\includeMPgraphic{base}
currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="(currentime)) scaled 2 shifted(0,2in)
withcolor magenta ;
for k=1 upto currentime: addto currentpicture also p[k]; endfor
setbounds currentpicture to TheFrame ;

desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );
\stopMPpage
}

\stoptext

Hi,

I don't know if \startMPinclusions \stopMPinclusions shall work with
\startMPpage and \stopMPpage. In this case, one can use a separate
graphics:

\startuseMPgraphic{base}

picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;
z1 = (60,40);
z2 = (40,90);
z3 = (10,70);

p1:=image(
label("Word 1", z1);
);

p2:=image(
label("Mot 2", z2);
);

p3:=image(
label("Parola 3", z3);
);

\stopuseMPgraphic

\starttext

\dorecurse{3}{ % Frame

\startMPpage[pagestate=start]

\includeMPgraphic{base}

currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="(currentime)) scaled 2 shifted(0,2in)
withcolor magenta ;
for k=1 upto currentime: addto currentpicture also p[k]; endfor
setbounds currentpicture to TheFrame ;

desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );
\stopMPpage
}

\stoptext

Hi Mikael,

here's a very simple mwe for the label(textext()) issue. On page 1, the text 
"Word 1" should be drawn in position z1. On page 2, the same text in the same 
position should be visible, and the text "Mot 2" in position p2 should be 
added. And so on.
\startMPinclusions
picture p[];
path TheFrame ;
TheFrame := fullsquare scaled 5in ;

z1 = (60,40);
z2 = (40,90);
z3 = (10,70);

p1:=image(
label(textext("Word 1"), z1);
);

p2:=image(
label(textext("Mot 2"), z2);
);

p3:=image(
label(textext("Parola 3"), z3);
);

\stopMPinclusions
\starttext
\dorecurse{3}{ % Frame
\startMPpage[pagestate=start]
currentime := #1 ;
% Just for learning :
draw TheFrame withpen pencircle scaled .1in withcolor magenta ;
draw textext("T="(currentime)) scaled 2 shifted(0,2in) withcolor 
magenta ;
for k=1 upto currentime: draw p[k]; endfor
setbounds currentpicture to TheFrame ;

desiredformat := 1080;% In pixels (will be converted by default at 72dpi)
currentpicture := currentpicture xysized (desiredformat ,desiredformat );

\stopMPpage
}

\stoptext

Hi Emanuel,

I am not sure I understand your question, and since you use fonts that
i do not have, I cannot test your example as is. But, maybe, if you
want to redraw a picture, you can do

addto currentpicture also p1;

where you want it.

/Mikael

PS For the text thing, I did not get it. Could one have a _very
simple_ example showing only that problem and no other problem?

You didn't specify the color of path A in p2 and p4. So it's drawn in black.
The other issue, I can't help.

Dear Aditya and Fabrice,
thanks for your responses.

I included some of Fabrice's code into mine for testing purpose, and indeed the 
multipage works now.
What is bizarre is that issues appear now that didn't appear before:
Path A is drawn with color red on page 1, and in color black on all following 
pages, while it should stay red.

textext(, ) is overwriting  with "T="(currentime) 
which has been used previously in textext() before the for k=1 endfor loop. 
This overwriting happens only for the first textext() which occurs inside the 
for k=1 endfor loop. All other textext() inside the for k=1 endfor loop are not 
drawn at all. If the line « draw textext("T="(currentime)) scaled 2 
shifted(0,2in) withcolor magenta ; » is commented out, the first textext() 
inside the for k=1 endfor loop is not drawn neither. It must be an issue with 
textext(), because when I replace textext() by lmt_outline[], the text is drawn.

A very similar option is to pass a variable to a metapost drawing. This is what 
I use:

https://adityam.github.io/context-blog/post/metapost-animation/

It only works when viewed in acrobat, you can just comment out the animation 
part and wrap it in \startTEXpage .. \stopTEXpage to get multi-page animation.

Hi,

It is fun fact very easy to do. You just use \startMPpage (…) \stopMPpage 
multiple times. Here is an example which build an animation of a particle 
moving according to a Brownian motion.
