Processing 1.0 - Processing Discourse - Multiple Key Detect Library

Most of the threads on the topic shown around 10 lines of code to handle the issue. I suppose you do sophisticated stuff. It isn't so hard to make a library, perhaps you should try and release your?

antiquekid3 YaBB Newbies Offline Posts: 13	Re: Multiple Key Detect Library Reply #2 - Nov 18^th, 2009, 12:45pm Well, if you're trying to detect numerous keys, it starts to be cumbersome. It'd just make sense to have a library since it is so commonly used. What do I need to do to make a library?

	Where is the what if the what is in why?

Well, Cedric, if I understood correctly, antiquekid3 knows how to handle multiple key input, but he is annoyed to cut and paste the same code in each sketch needing it.
Indeed, sometime you have some simple code you want to use in several sketches, and currently Processing doesn't facilitate simple reuse, like looking in a shared code folder. I recall I suggested such feature long ago, as wrapping the code in a jar is sometime inconvenient, particularly if the shared code is still evolving.

Cedric YaBB Moderator Offline Posts: 1838	Re: Multiple Key Detect Library Reply #6 - Nov 19^th, 2009, 1:30am i see... i keep one copy&pasting as long as there is no other way. but it doesnt bother me alot. The question is where to start? you dont wanna have a librarie for every little snipped available that solves some little problem ... http://snippet.seltar.org/index.php

I wonder if Unix-like systems can just use symbolic links for .java or .pde files.

Yes, that's quite right. For example, it would seem like a waste of time to detect a-z, A-Z, 0-9, all the symbols, space, return, etc. if you're just going to use two keys in one of your programs. However, in some other programs, that might be useful; hence the need for a library.

Yeah, I hate the copy/paste stuff. Maybe I'm lazy, but it's pretty annoying to go back over each program that uses the same part when you figure out how to make something better.

The way I have handled multi-key input doesn't seem as complicated to me as what the first link showed, but I guess mine might take up a few more lines of code. But it's easier for me to understand.

You can simply put your class in a ruby file, and then require it on the top of your scetch..I have no clue about how to create .jar files, but it seems more complicated then the rubyish way How you even can create a larger sketch without outsourcing stuff?!I would get crazy

Nicolas ATEK YaBB Newbies Offline Posts: 6	Re: Multiple Key Detect Library Reply #10 - Nov 21^st, 2009, 1:43pm I am working on a game library 'Glib' used to facilitate games creation with its sprite engine. It also contains 2 input functions atm that works well with multiple keys: - glib.KeyDown(key) - glib.keyHit(key) Hope to release a beta soon

Nice! I can't wait to try it out! That's just the thing I'm looking for, really. Let us know when you finish!

PhiLho YaBB Moderator Offline Posts: 4190 Near Paris (France)	Re: Multiple Key Detect Library Reply #12 - Nov 22^nd, 2009, 1:22am Nicolas, this is a good idea, but you should rename your library, GLib is already a well known name in the programming world... Perhaps p5glib to be in the tradition of Processing libraries, or something like that.
