Hi everyone.
I’m doing an installation for a project, this is my stand point.
What do I want to achieve:
A program that display a word-cloud (the more a specific word has been say, the bigger it appears in the word cloud).
The input will be a microphone, the program will detect the word and then display it. (it will start with 0 word and then the number will incresce depending on how oft people will interact with it. The font size of the words already displayed should change and adapt in order to keep the chart true).
The code now:
I took two code I found online and I merge and edit them. The code integrate the function to detect the word from the microphone and display it in the console (is not yet displayed in the world-cloud).
The text to form the cloud now is an external text file (witch is not necessary but I keep it for testing).
When I run the sketch and I edit the text file (already full) and save it (with the sketch running) it does not update. I can’t really understand why.
If I run the sketch with only one word on it, then I add a new one and I save the text file, the code some times display the new word (smaller compere to the first one even if is repeated) other times he just repeat the last word he displayed but smaller then the previous one).
Help
I’m a beginner in processing, I would like if someone could take the time to guide me in order to fully understand the code and help me out to get the code running the way I would like it to.
here a link to download the zipped code with the text file and font

Thanks
