I'm trying to use a custom shapes library it works fine in the editor but when I export to a jar file I get a no class def found error
I have the library in Program Files (x86)\Greenfoot\lib\userlib and in project/libs (I made the libs folder)
I other discusions said to add this :
static {
final NativeLoader loader = new NativeLoader();
loader.addClasspath( "./+libs/jshapes.jar" );
loader.loadClass( "sl.shapes.StarPolygon");
}
to the world class (I assume outside of any method)
but greenfoot can't find NativeLoader and I couldn't find where to import it from.
So where do I import it from and is my code/library location correct?
