Proceed to Next Level

Troubleshooting General Help
1

Hi guys. So I’m making a game for a project in my class and I really wanted mine to stand out so I went for jMonkey. I have been with this since Feb this year so I am quite a noob and as early as now, I would like to apologize for any consequences that my noobness can cause.

Anyways, my game must comprise of different levels and I have already successfully made one already - in its own class (WithWater). In an attempt to test switching or transitioning to the next level, I copied and refactored it. Here is where I got stuck. I have no idea how to call refactored class (the next level).

Basically I have a thread which plays music (I am using jlayer) and when it should end, the game should then take the player to a new level. I have already read about appstates but I’m just not sure on how to use them. Can you please help me and try to explain them to me a bit?

Here is the code for the original “WithWater” class

theres a lot of ways to implement this sort of thing…

to use an app state you just make a class that extends AbstractAppState instead of SimpleApplication, and then do stateManager.attach(new YourLevelAppState());. its not that different from writing your code directly in simple application.

you’ll probably want an app state for each level.

Thanks. I do get that idea of having an app state for each level. My problem now is how do I sort of “translate” my SimpleApplication into a class extending AbstractAppState? I am currently in the process of doing so but it wouldn’t allow me to implement PhysicsCollisionListener like the SimpleApplication would allow me.

Sure it would. But we can’t help with errors we aren’t told about.

Please tell me if I’m wrong, but I think I do not need to implement PhysicsCollisionListener anymore in a class that extends AbstractAppState? I got this after reading several resources.

@pspeed said: Sure it would. But we can't help with errors we aren't told about.

Don’t mind my previous post about not needing to implement PhysicsCollisionListener… Anyways, I get a ‘{’ expected error when I try extending AbstractAppState then implementing PhysicsCollisionListener and the whole public class BoaterAppState extends AbstractAppState, implements PhysicsCollisionListener is underlined in red.

I have no idea what you are trying to do so I can’t comment on a guess. But you said “wouldn’t allow me to” which isn’t true. You can have an app state implement PhysicsCollisionListener and add/remove it from the space as needed. Nothing prevents it.

…whether you will want to or not is an entirely different matter.

I get the point. Maybe putting up my code for the class extending AbstractAppState would help. The main problem I have here is to “translate” my class extending SimpleApplication (the one with the code posted above) to one extending AbstractAppState. (that is why I am looking for ways to implement PhysicsCollisionListener).

I apologize for all the stuff in this code that might confuse you. I am just a noob but I am really trying my best to find a way to sort this out. :slight_smile:

UPDATE: I have already sorted out the problem and am now able to run my game via a class extending an AbstractAppState. Thanks for all your help guys.
