Slick2D音乐无法正常工作

Question

I am currently testing Slick2D and thats why i am writing a Pong Game, Also, in this PongGame you can select Music Files, which are in the ./music Folder

When i run it through Eclipse, all works perfectly. When i export it, run it with all natives and Librarys in the Folder, it also starts, but the Music Menu does not work (It just crashes when i select a Music)

The code you can see on: https://bitbucket.org/JohnnyCrazy/pingpong/src/f2fd635ccfef/src/me/Johnny/Slick2D?at=master

I don't understand why it works in Eclipse and exported it doesn't.

Answer 1

The JavaDocs for the constructor of Music(String) are not entirely clear on how it interprets the String . J2SE methods that take a String typically presume it to represent the path to a File . If that is the case, that is also the reason behind the failure.

Typically those types of resources become an embedded-resource when the app. is built. An embedded resource must be accessed by URL . See the embedded resource info. page for tips on forming the URL .
