Currently I'm working on a new desktop app for a family reunion. I started out hoping this would be a two day and done, but when I actually started coding I realized I was in a bit deeper than I had previously thought. So here's to explaining my app.
This app requires 2 windows to be constantly open and running, however both of these windows need constant communication.
The audience cannot see the control window, but rather only the pretty display, this allows for the audience to never see an annoying mouse moving around. I couldn't figure out any other way to do this the way I want with libgdx without multi threading.
I started this project by trying to create two windows using libgdx (however I didn't actually want libgdx for control) but I wanted to see if it was possible. I quickly learned that openAL does not allow libgdx to do that, so I quickly switched over to Swing to make sure that I could in fact actually still accomplish 2 windows (and not "pop ups").
So I started working at this app got a bit of the GUI out of the way then went on to the next challenge of communicating between these threads. Now the way that libgdx works you can't manage the threads a whole lot from the original class to start the threads, or at least in terms of passing around data.
The solution? A class I call DataPassage, with all variables being static. The static variables allow me to access the data from anywhere without having to directly pass it to each class. DataPassage nicely handles all variables inside. This helps in two ways.
#1) Cuts down in data on the heap.
#2) Organizes all variables and keeps it all in sync.
Now would I recommend this for all variables in every situation? No, but definitely useful in a lot of situations. Would I recommend this if you are struggling in a situation like mine? Yes. Just be sure to not be storing the variables in all 3 classes, and rather only in the DataPassage class.
