question about color coding and twitter4j

in Contributed Library Questions  •  1 year ago  
hello processing geniuses, 

im working on a logo that involves a harmonious group of particles that revolves around a letterform; i need some help with the particles. so heres the gist of it: each particle is generated by a tweet that consist of six different keywords: air and space, creative court, ecosystems, innovation lab, rain forest, and world of life. each keyword is represented by different colored particles, as shown below:
air and space tweet : dark purple particle
creative court tweet: orange particle
eco systems tweet : blue  particle
innovation lab tweet : pink  particle
rain forest tweet : green  particle
world of life tweet : red  particle
the differentiation of the colors, once the particles are generated by twitter feeds, allow the user to see just about which topic is most popular; if  green particles seem to populate the space more so than other colors, they get a clearer sense that the topic of rain forests is most talked about.
heres my question: for my set of codes, i was wondering if you guys can help me write how i can make this function possible.
also, i was wondering if you guys can help me how to tie in the twitter feed function to my code.
for now, the particles can be generated by clicking the screen.

for the processing code, i have set two tabs to reduce the clustering of codes.

if you prefer the actual code, you can download it here:  http://www.mediafire.com/?zqach4y6p6vb4qj

note: the gradient function is very important, so the twitter function is powered by twitter4j.

thanks! much appreciated

I can't even test your Code, I get an error at
Copy code
  1. Twitter twitter;
and I couldn't figure out how to use the library...

I tried this before, I don't know what's going on...

Re: Re: question about color coding and twitter4j

i think what you have to do is download the twitter4j-2.2.5 plug-in, place their folder (mac) finder > document > processing, go to twitter4j-2.2.5 > lib, and drag the java jar file called "twitter4j-core-2.2.5" into the processing document.

if that doesnt work, you can delete the twitter4j functions in the processing file.

good question by the way, i totally forgot about that. the problem with twitter4j-2.2.5 is that even though you have all the files, the file "twitter4j-core-2.2.5", has to be placed in the document page, and then dragged into the processing file.

now it's running.

but as I said I have no idea about this twitter4j

you have to put more twitter-stuff into draw() as I said

Re: Re: question about color coding and twitter4j

do you know how i can allow keywords to generate color-coded particles?

air and space tweet : dark purple particle
creative court tweet: orange particle
eco systems tweet : blue  particle
innovation lab tweet : pink  particle
rain forest tweet : green  particle
world of life tweet : red  particle

use switch

...

case " air and space"
fill (col11);
break;

Re: question about color coding and twitter4j

Anyway, I played with it a little.

Instead of using switch I build an array of colors (called "myCoolColorsForEachWord").

Your "terms" array must have the same size as those colors obviously, because they use the same index.

The program is dead slow.  
This is because of getMsg.
Maybe you find a way of loading it asynchronous.

At the moment I use draw() as a loop and check for the next word (it is given by index which is used in getMsg) every 121 times or so only.
I pulled getMsg out of your class.

Greetings, Chrisir
