Hello,
I noticed that when changing the name of a light, it does not register directly. I added the RenameLightOperation class that seemed to be missing
Could you change the target branch of your PR to develop branch, please?
it’s done

Hello,
These are options for copying and pasting a node from the scenegraph.
Icons are not created yet
cool, I’ll look at it little later 
Hello,
In JMB, a NullPointerException is thrown in the RenameLightOperation class because the Light object has a Null name when it is generated.
I made a change, can you see if it fits?
Your fix adds default names to lights, it isn’t the best option in this case, I think we need to add support to work with null names of lights because some lights can be created from external systems. (blender loader or something else).
I have pushed my fix of this:
Ok

Hello,
for no apparent reason, my classes controllers no longer load.
I always have the following warning:
WARNING 19:46:23:319 ClassPathScannerImpl: Can't load class: mygame\Ctrl\InterrupteurCtrl
WARNING 19:46:23:320 ClassPathScannerImpl: java.lang.NoClassDefFoundError: mygame\Ctrl\InterrupteurCtrl (wrong name: mygame/Ctrl/InterrupteurCtrl)
at java.lang.ClassLoader.defineClass1(Native Method)
at java.lang.ClassLoader.defineClass(ClassLoader.java:763)
at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142)
...
I did not change anything in my users classes folder.
the exeption starts in class ClassPathScannerImpl :: loadClass of the library rlib
I do not understand the problem, I did not change anything
could you show your libraries settings in jMB, please?
I think it’s a problem with replacing slashes to dots:
I did a test:
I added this line:
private void loadClass(@NotNull final String name, @NotNull final Array<Class<?>> container) {
if (!name.endsWith(CLASS_EXTENSION)) return;
String className;
try {
className = name.replace(CLASS_EXTENSION, StringUtils.EMPTY);
final StringBuilder result = new StringBuilder(className.length());
for (int i = 0, length = className.length(); i < length; i++) {
char ch = className.charAt(i);
if(ch == '/') ch = '.';
if(ch == '\\') ch = '.'; <---------- here
result.append(ch);
}
className = result.toString();
} catch (final Exception e) {
LOGGER.warning(this, "Incorrect replaced " + name +
" to java path, used separator " + File.separator);
return;
}
the controllers load well but then I noticed an exception in the class CreateCustomControlDialog (line 172) of type NoClassDefFoundError on the loading of a com.jme.ai.navmesh class.
I I captured the exeption java.lang.NoClassDefFoundError and it works then.
yeah, I will update RLib a little bit later, because I’m working on improving high performance network system in this library now
I have updated jME and RLib in the develop branch
With the changes made to rlib library, an exeption rises in the CreateCustomControlDialog code
line 171:
final Array<Class<Control>> implementations = CLASSPATH_MANAGER.findImplements(Control.class);
implementations.forEach(items, (cs, classes) -> ClassUtils.hasConstructor(cs),
(controlClass, classes) -> classes.add(controlClass));
In my case:
Exception in thread "JavaFX Application Thread" java.lang.NoClassDefFoundError: com/jme3/ai/navmesh/NavMesh
at java.lang.Class.getDeclaredConstructors0(Native Method)
at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671)
at java.lang.Class.getConstructors(Class.java:1651)
at com.ss.rlib.util.ClassUtils.hasConstructor(ClassUtils.java:101)
I corrected by capturing the exception but I do not know if the problem comes from the other hand:
for(Class<Control> c : implementations){
try{
if(ClassUtils.hasConstructor(c));
items.add(c);
}catch(java.lang.NoClassDefFoundError error){}
}could you show full exception log, please?
