writing externs that call methods of objects through outlets
by Mike Wozniewski 25 May '05

25 May '05

Hi, I'm writing an external and I would like instances of my external to directly call methods in objects attached to it's outlets. Strange, yes, but I would like to see if it's possible. I have a piece of code I found in a post that traverses the outlets using obj_nexttraverseoutlet and returns t_object pointers. This is very cool, but how do I call methods given the t_objects? In fact, what is a t_object? Heres's the code. For now it just prints the class type of the connected objects. void myfunction(t_myobj *x) { post("these are the types of objects we feed:"); t_object *src, *dest; src = &(x->x_obj); t_outconnect *oc; t_outlet *op; t_inlet *ip; int outno = obj_noutlets(src); int inno; while (outno--) { oc = obj_starttraverseoutlet(src, &op, outno); while (oc) { oc = obj_nexttraverseoutlet(oc, &dest, &ip, &inno); post("\t-> [%s]", class_getname(*(t_pd *)dest)); } } } Any help is greatly appreciated. Thanks, Mike Wozniewski

cpu load indicator..
by adam armfield 25 May '05

25 May '05

i've been reading articles on http://paulgraham.com/articles.html can't remember which one it was, but in one essay he suggests a language/environment can highlight parts of the program that are cpu bottlenecks, i thought this might be a nice feature for pd, some kind of mode or object which changes objects different colours (for instance) depending on how much cpu they are using there might be objects that do this already, i haven't checked ;-) another one i've been mulling over is some kind of linux style tab autocomplete feature which guesses the name of the object one is creating when tab is pressed.. maybe could speed things up a bit all the best adam ___________________________________________________________ How much free photo storage do you get?

Re: [PD] pixelTango trouble
by shreeswifty 25 May '05

Hi Ben I was browsing your stuff and it looked pretty spiffy, i must say. I am hoping to get a nice suite of tools for live performances this summer and pixelTango seemed like a nice compliment to GEM, PiDiP, and GRIDFLOW. All the help patches open fine but the examples would not. I did not use the installer recommended because of my patched build for Jamie's Stuff. I still say we need to connect the pixelTango/GEM/Pidip/Gridflow to the AccessGrid next AGNODE._pd.darwin anyone. ? :-) I am pretty sure i am using python 2.3 (because of scons/csoudn stuff) what do you suggest?

pd -nogui (windows) strange behavior
by Lazzaro Nicolò Ciccolella 25 May '05

25 May '05

Hi all, I had upgraded pd to 0.38.3 (win binaries downloaded from Miller Puckette's web site) starting pd with "-nogui" flag, cause strange behavior: the computer reacts very-very slowly to the user input. The task-manager marks 100% cpu loaded (Pentiom IV 2.8G). Without the option -nogui PD works perfectly. Thanks for whichever aid -- Lazzaro
