Hi,
Newbie with jMonkey, I am teaching tutorials to better understand your “seems to be” awesome engine 
I am currently teaching AppState thanks to the common tutorial. My remark is about the proposed update() method :
[java] @Override
public void update(float tpf) {
if(isEnabled()){
// do the following while game is RUNNING
System.out.println(“Enabled”);
} else {
// do the following while game is PAUSED, e.g. play an idle animation.
System.out.println(“Disabled”);
}
}[/java]
When this appstate is enable, at each frame, I have a new “Enabled” in the console. But I never see “Disabled”
To understand why I look at AppStateManager source code and particulary at the update method :
[java] for (AppState state : array){
if (state.isEnabled()) {
state.update(tpf);
}
}[/java]
The condition on the enable state of each appstate prevent from running them if they are disable, seems to be ok.
Is the tutorial outdated ?
Thanks.

It does look rather like it might be…
If the AppState is disable, the else part of code is never launch :
[java]
if(isEnabled()){
// do the following while game is RUNNING
…
} else {
// do the following while game is PAUSED, e.g. play an idle animation.
…
}[/java]
This is correct… disabled app states are not called. The tutorial must be ancient because update() has never been called on a disabled app state for as long as I’ve been using them.
I modified the tutorial.

So the better way to display some “pause” stuff is to put the code in the @Overrided setEnabled(boolean b) method ?

Or add a separate PausedAppState and disable the main one. Remove the paused app state when you are ready to resume and re-enable the main game app state.
Personally, I consider the "disabled" state of an AppState to mean that it's no longer doing anything and has cleaned the relevant stuff from the scene. So, for example, a HudState would completely hide or remove its stuff if disabled. A main game state might be different and I don't know how you are actually pausing it, ie: keeping the regular keys from working, etc..
