Troubleshooting

Why did the app crash?

Take a look at log.txt (it's in the same folder as Midi Wars). It should let you know what went wrong and why.

What if log.txt is empty?

If log.txt is empty, that the problem is likely related to the Launcher (Windows-only). Instead of double clicking Midi Wars to launch it, open a terminal and launch it by typing java -jar MidiWars.jar. If there's an error not showing in the log file, you should see it here. If you still can't find out what went wrong, feel free to create a new issue explaining your problem.

Typing in chat while playing a song is very glitchy. Is this normal?

Unfortunately, yes. This functionality is unstable by nature, so there's not much I can do about it.

I'm seeing random numbers being type in the chat.

This may sometimes happen when you're playing a song with a fast tempo and trying to type in chat at the same time. Like I said above, this functionality is not stable, so this is one of its problems. Simply close the chat, by pressing Esc, to resume regular playback.

I find it very hard to press modifier keys, such as typing the exclamation mark by pressing Shift + 1.

This usually happens with songs that have faster tempos. That's because modifier keys (Ctrl, Shift, Alt, etc) need to be released when playing a note. Just keep trying and press the keys as fast as you can - you'll eventually be able to type what you want.

Again, this is one of the problems associated with the very nature of the functionality.
