Converting to BaseGame framework from SimplePassGame.. nothing renders

Troubleshooting General Help
1

Here's a HUGE mass of code, nothing renders but the Tile-Loader reports creating everything and I see the skybox created in the output, as well.

Don't take this the wrong way, but this forum is not really meant as a personal debugging tool.  :slight_smile:

As I understand, this forum is here to allow the jME community to collaborate and for more experienced coders to help less experienced coders. If we don't help each other, we'll never learn. If people are discouraged by the fact that nobody is helping them, they won't stick around to be a part of the jME community. (For instance this thread)

While I understand it's not just a debugging tool, when I see a forum that I can help on, I gladly post solutions to problems, so I see nothing wrong with requesting that help from others.

Isn't there supposed to be an update at the end of your init method… or am I missing something?

You're right, it is  :wink:

first of all:


        terrainNode.updateGeometricState(tpf, false);
        waterNode.updateGeometricState(tpf, false);
        pManager.updatePasses(tpf);



is meant to happen in update(), not in render().

You might want to take a look at the test classes in the jme source  :)

so long,

Last night I printed out the source for BaseGame, BaseSimpleGame, and SimplePassGame to see what they are rendering and updating that I may have missed.

But because it was so late I fell asleep at my desk! :D

I meant the classes TestBaseGame, TestSimplePassGame, and such. They show you how the classes you mentioned should be used  ;)

Sure, but if you don't understand your own code enough to narrow it down to some smaller chunk of code then you probably need to take a step back.  Posting a whole class and saying "what's wrong with this" is a bit much, imho.

agree with renanse…

I totally agree with renanse and MrCoder.



Trussell, please remember that when you started your very ambitious project everybody kept telling you to take that step back and start with simpler things. You rejected that advice, and sometimes even in an almost aggressive manner.



That advice was the best, and sometimes the only answer to many of the questions you have asked here since then.  You could have answered a lot of those questions yourself if you had started at a reasonable level and pace.



Sorry if this sounds like I'm bashing you, I really don't mean to.

But you have to understand that it is pretty inappropriate to refuse learning jME at a reasonable pace and then come back with two or three questions a day about some really basic things.



Again, if this sounds overly harsh in your ears, I apologize. A lot. You have answered some questions on the forum, and in a nice and informed way too, which must be recognized. But that's not the point here. I hope you understand :slight_smile:



(EDIT: just removed a litte redundant jabbering. nothing important.)

Well, I didn't pay much attention to it at the time because I haven't become very familiar with Renanse, so I thought it may be him just being annoyed with me. The large (or what I would consider to be sufficient) group of people that agreed with him made me think.



I went back and took a look at all of my posts, and I find that in my excitement to make progress with my game I posted many problems that I solved immediately after posting.



I would like to apologize for my voracious posting habits. I will try my best to keep my posts more relevant and not so  obvious. I understand that this can be annoying for you. Once more, I am sorry.
