Crash using BasicFrameListener

Hi all!

I've just got OgreNewt working or so I thought.
After adding the following two lines:

mOgreNewtListener = new OgreNewt::BasicFrameListener( mWindow, mSceneMgr, m_pNewtWorld, 50 );
mRoot->addFrameListener( mOgreNewtListener );

My program crashes out with this message:

First-chance exception at 0x005c17fd (msvcp80d.dll) in TowersTA.exe: 0xC0000005: Access violation writing location 0x0000000f.
Unhandled exception at 0x005c17fd (msvcp80d.dll) in TowersTA.exe: 0xC0000005: Access violation writing location 0x0000000f.

It occures AFTER framestarted() is called, and BEFORE endframe() gets called. It's causing me a huge headache.

Also, what the basicFrameListener() actually used for?
Thanks in advance guys!

I had a similar problem recently.

Can you give more information on the line where it crashes and the callstack on crash?

I can't really give any more info about the error, but here's a screenshot at the breakage point


Will be glad to hear if you have any clues.
Again, what is the method BasicFrameListener call actually used for?

The BasicFrameListener is the method that calls updates on the physic world. (Updates positions, collisions, etc..) Unless you do a frame listener that fills this job, you'll have to use it.

I had the same error actually. I fixed it by removing every lines writing in ogre log. So basically every lines that contains strings.

I know it's more of a quick hack than a real fix but it works. :/

Once these lines are removed,don't forget to rebuild the wrapper!

Well I have managed to get the physics world to update, by calling
ogreNewtWorld->update(delta time

Thanks for the help, but I don't really want to get rid of the loggers functionality

I'm getting the same error, i think.

The end of ogre.log:

...
03:02:25: Win32Input8: Establishing keyboard input.
03:02:25: Win32Input8: Keyboard input established.
03:02:25: Win32Input8: Initializing mouse input in immediate mode.

03:02:25: Win32Input8: DirectInput OK.
03:02:25: Newton Frame Listener... m_elapsed: 0 m_update:0.0166667


After this the tutorial 1 application (http://www.ogre3d.org/wiki/index.php/Newton_Game_Dynamics) launch the exception:
First-chance exception at 0x005b17fd (msvcp80d.dll) in TesteFisicas.exe: 0xC0000005: Access violation writing location 0x0000000f.
Unhandled exception at 0x005b17fd (msvcp80d.dll) in TesteFisicas.exe: 0xC0000005: Access violation writing location 0x0000000f.


So, i think the "ogreNewtWorld->update(delta time)" should solve the problem, but i don't know were to put this call... and what deltatime should i define.

frameStarted / frameEnded would be a sencible place to put:
ogreNewtWorld->update(delta time)

Where delta time is the time, in milliseconds (not too sure, you'll have to check the doc), since the last update call

I used this method - I never did get the framelisteners working. But I still have problems with objects getting stuck in the air.

So, i was able to solve my problem out.
how? There goes:

1- I've build a BasicFrameListener class, much like the OgreNewt::BasicFrameListener, but with out debuging options. This as solved the exception problem.

2- Then your problem had came to my program so i've been looking in the forum, and in my case my world size was to small and the objects were out of the world. The world default size is -100,-100,-100 to 100,100,100. To set a new one, i have defined in the contructor...

OgreNewtApplication::OgreNewtApplication(void)
{
mWorld = new OgreNewt::World();
mWorld->setWorldSize(Vector3(-500,-500,-500),Vector3(500,500,500));
}



Now, i will try to put debugging working because i'm having some bouncing problems.

That's fantastic! Thanks for the info.

Always turns out to be just an obvious or simple cause.

I'll give it a try when I get the chance

I too have got it working in release build by increasing the size of the World so thanks.
It still crashes in debug though... did you get any success?
