1  Java Game APIs & Engines / Java Sound & OpenAL / Multi-threaded sound crashes on: 2012-02-07 16:47:25
Hello, I've been working on a danmaku shoot-em-up game using my own game engine for a while now. In my game, there are usually many bullets being fired by both the player and the enemies. So I built my sound code so using threads to handle each instance of a sound playing. This enables  multiple instances of a sound to be played at the same time.

This works completely fine for me! For one of my testers though, the game and his JRE randomly crashes when it finishes playing sounds without throwing any sort of exception. He's sent me his log file, and the problem seems to occur where I drain the remaining data from the sound's line after reading it in.

I've posted my question on Stack Overflow, with an SSCCE to demonstrate my problem. I've also provided there a log generated by my tester's JRE upon the crash  So instead of reposting it here, here's the link:

Any insight from you sound/threading gurus out there would be helpful.

ok, I understand now. I haven't tested my game in a Linux environment.

I don't think it's difficult to install. Just extract the zip contents and run the shortcut to the game's jar file.

Since this was for the most part an academic project, I've also released an open-source zip of the game. That can be downloaded here:

If anyone has any idea why it is being laggy/sound jumpy for some users and has some advice on how to fix it, please let me know.

That's strange. I'm not experiencing any lag or jumpy sounds at all.

[size=20pt]Wumplus World[/size]

Hello everyone, this is my first time posting here on I would like to present a game I developed this semester as a project for an artificial intelligence class: Wumplus World!

Wumplus World is a variation of a simple dungeon-crawler game called Hunt the Wumpus. The hero must explore a dark cave to try to find the gold hidden within. However, the the cave is also filled with pits and it is home to the smelly, ill-tempered Wumpus who wants to eat the hero! The cave is also home to the Wumpus's friendlier cousin, the Supmuw! The hero's goal is to find the gold, not die, and escape back to the entrance of the cave.

Further instructions are included in-game. The user can choose to either play the game in human-controlled mode, or watch the game's artificial intelligence agent to try to navigate the cave.
