This problem might seem a bit trivial, but I seem to be pulling my brain out along with my hairs trying to work this one out.
Basically, I have a “New Game” button, which once clicked, takes me to another screen which lets me choose story or custom game.
When I click the New Game button, it also plays an audio file, no problemo, however once in the other screen, I click “Back” to go back to the main menu and click the “New Game” button again, the game crashes with a nullPointerException.
I’ve been doing some digging online (as we do), and haven’t really found any solution other than other people’s custom audio loading classes, which I can learn off if I actually NEED to.
I have also looked at the LibGDX documentation about using an AssetManager (https://github.com/libgdx/libgdx/wiki/Managing-your-assets), which I believe is probably going to solve a few problems for me, more so than just this one.
What I am wondering is WHY I would be getting a nullpointerException when the audio plays fine the first time, but not the second.
What I am also wondering, is if I am heading in the right direction here?
Should I be using the AssetManager, or writing my own audio loading class and asset caching class? Because honestly without using someone elses code as reference, I would have no idea where to start with doing the latter.
As always, I am looking for direction, not a direct answer as I need to learn to problem solve and learn these things myself, not have it handed to me on a silver platter.
Any help would be greatly appreciated, I will continue to search for a solution or some insight as to WHY I would be getting a null pointer in this scenario.
EDIT: I have found this tutorial here which I think may be helpfuly.
I am thinking that once I play the audio, I need to store the ID into a Long variable type, and refer to that ID when I want to do something with it again, am I correct or no idea?
