Resolution:
User Error (my version of HelloJME3, I failed to put in the line mat.setColor(…))
When I was running the Jmonkeyplatform.exe (I was running with 32bit vm on 64x windows…which I think caused it to not render properly…it is now working that I re-installed 64 jvm).
Hi folks, just downloaded the alpha, and trying to get the first tutorial working…when it fires up, and run it full screen or not, using LWGL-OPenGL2, or any other option on the drop down, the window just appear black, with the 'text' hud displayed at the bottom.
I'm running on windows 7 - 64bit.
My class path includes every jar from: jme3root/jmonkeyplatform/libs
I didn't see any mention of adding the lwgl dll's to the path? is it not needed? and if so which version (i tried 2.2.1 still nothing).
here is the output in the console (running this from eclipse)

any points greatly apprecaited 
note: jme2.0.1 works just fine, when I include lwgl-2.2.1 in the path. (I see from the above log that it is indeed using the ldwgl 2.4.2 included in the jmonkeyplatform root.
also of note: i get the same blank screen (i.e. no graphics are ever rendering), when I run demos via the jmonkeyplatform.exe
I think it might help, if you add following code in the line 152 of the class LwjglAbstractDisplay:
new Exception().printStackTrace();
and let us know resulting stacktrace.
hmm, maybe my version of the class is different then yours…but the stack is not very useful.
java.lang.Exception
at com.jme3.system.lwjgl.LwjglAbstractDisplay.run(LwjglAbstractDisplay.java:151)
at java.lang.Thread.run(Unknown Source)
The function is the thread run() (line 152 is bolded)
and is:
public void run(){
logger.info("Using LWJGL "+Sys.getVersion());
initInThread();
while (true){
if (Display.isCloseRequested())
listener.requestClose(false);
new Exception().printStackTrace();
if (wasActive != Display.isActive()){
if (!wasActive){
listener.gainFocus();
wasActive = true;
}else{
listener.loseFocus();
wasActive = false;
}
}
runLoop();
if (needClose.get())
break;
}
deinitInThread();
}
Ye seems you got different classes (hm I believe I updated them only couple days ago).
Any way you need to put this line somewhere there (method deinitInThread):
/**
* De-initialize in the OpenGL thread.
*/
protected void deinitInThread() {
listener.destroy();
if (Display.isCreated()) {
renderer.cleanup();
Display.destroy();
}
logger.info("Display destroyed.");
super.internalDestroy();
}
yeah…it turns out it was user error (see initial post on this thread), thanx for the tips though
