"The left line is missing on the box"

code:

beginShape();
vertex(30, 20);
vertex(85, 20);
vertex(85, 75);
vertex(30, 75);
endShape();


I'm using version 0121 beta

that's not a bug. please see the up-to-date reference on the site or
included with your software. or if you've been using versions prior to
0115, heed the notice next to the download link that says "Read before
downloading 0116+".

Can\'t seem to figure out your help?

we are several studens using the same Version \

read "revisions.txt", specifically the section "beginShape() has changed"
under the notes for revision 0116.

also read the reference, look at the third and fourth examples on this page:
http://processing.org/reference/beginShape_.html
the third example is your code. the fourth is the code for what you want.

actually, i meant the fourth and fifth--the fourth example on that page is
your code. the fifth is what you want.
