There's a big mistake where you do the data subpatch traversal: There is no subpatch [pd 1_table] in your patch but still you try to do a [traverse pd-1_table(. Instead there is a [pd $1_table] subpatch. You should use something like [symbol pd-$1_table] | [traverse $1( instead, if you're using Pd 0.40, or [symbol $1_table] | [makefilename pd-%s] | [traverse $1( for older Pds. > and some things I would like to improve: > - I would like to limit init and end point rango between 0 and 100, that way > I could't drag either the init point down to 0 or the end point up to 100. Check out the 09.scaling.pd help patch in the docs. You need to use a different syntax to paint, it looks something like this "x(0:100)(0:100)" However for what you want to do, you need to change other parts of the patch as well and intruduce a "dummy-X"-coordinate. See attached patch. > - I don't know why I have two times the init and end markers (I only want > one init marker and another end marker) Probably one was saved with the patch. If you clear the subpatch and put the markers on again, everything's fine. > - How can I modify either the init or end markers from an external value > (via receive) You can send and receive pointers. Just get a pointer to one of the markers using for example traversal, then send that pointer somewhere, where you have a [set init x] object or so. You can also store the received pointer in a [pointer] object, if you want to reuse it several times just like a [float] or [symbol]. Ciao -- Frank Barknecht _ ______footils.org_ __goto10.org__
