hi all,
i ve been having the same problem with other applications i've created earlier,when i hit an object in the scene such as,character,light or camera ,it throws me this error exception, i have no clue why that happens,all i know is that it only happen in the opengl mode unlikely in the directx mode,any clue on how to get that fixed?
thanks in advance ,
Romy
btw this is the tutorial ive been following along : http://www.ogre3d.org/tikiwiki/Basic+Tu ... =Tutorials

Your probably trying to do something to a pointer thats null. What do get when you click "break" and look at you call stack?

Step into the code and see which lines is firing the exception. After that, put a break point a few lines before. Step in again and see if any of those values are null... and then you will have to back track to see why... can you recollect more information. how about the ogre.log file.

i just pressed f9 in the first lines and then kept pressing f10 till it loads the game scene then i ran the game camera towards the ninja character in order to trigger the access violation exception error and then pressed Break and took a screenshot..im not sure if that is what u wanted to say but if not please lemme know how to debugg it coz i forgot how to do that since its been months dat i dont watch c++ tutorials..
thanx in adavance,
Romulo

about the ogre.log file i dont know where it is located at,sorry if that sounds dumb to u but im pretty new to ogre tho..if u mean the visual studio output window then here it goes:

It is ok to be new.

I would try to start from scratch and do it all over again...
First, download the pre-built sdk
http://sourceforge.net/projects/ogre/fi ... e/download
for instructions go to http://www.ogre3d.org/tikiwiki/Installing+the+Ogre+SDK

then follow the instructions here. Except, that note that it says Boost_144 and the folder you have comes with 147.
http://www.ogre3d.org/tikiwiki/Setting+ ... ual+Studio

and then do tutorial 1.
http://www.ogre3d.org/tikiwiki/Basic+Tu ... =Tutorials

make sure you follow all the steps and let us know at what step of those tutorials you are having trouble.

As far as debugging, I found 2 links in how to debug using google : "How to debug visual studio 2010"
video (part 1 of 3):
http://www.youtube.com/watch?v=z5gBIizwsY0
and just standard tutorial
http://www.codeproject.com/Articles/795 ... 0-A-Beginn

as far as the ogre.log, that will be found by default in the bin directory where your .exe file is. If you follow the instructions i how to set up an application of visual studio, you will notice that copies the files to the directory... you could also do a search in your system for ogre.log and figure out which one it is by the content of it. you can open it with notepad,notepad++ or any editor (it is a text file.)

I have to say, while I'm not new at programming, I'm new at Ogre, and here you will find a community that wants to help you. It is hard for most programmers (at least for me) to be able to tell you what problem someone has by the exception error you have... I'm not sure what is your programming background, but like the first person replied, it is probably a null pointer.

We have a great forum, for problems not relating to ogre, but more to programming which is call "Back to basics" [url http://ogre3d.org/forums/viewforum.php?f=10][/url]

I hope this helps. Once you have gone thru the steps I have suggested, let us know where you are stock, so we can help you.

thanks

Hi bro how u doing man?

thanks for understanding the fact that im a newbie and need to learn a lot of stuff yet...i started from scratch and fixed the errors..
first of all the "mSceneMgr->getRootSceneNode()->createChildSceneNode()->attachObject(entNinja);" line was located bellow the setCastShadows(true) line and also bellow the setAmbientLight and some other stuff..
in second comes the "directionalLight->setDirection(0,1,1);" line, it was looking like this : "directionalLight->setDirection(Ogre::Vector3(0,-1,1));" so i fixed it and also the seDirection was located bellow the "directionalLight->setDiffuseColour(0.25,0.25,0);directionalLight->setSpecularColour(0.25,0.25,0);" lines so i moved it up and fixed it,so everything now is looking fine and no more errors!!
thx for ur efforts dude i really appreciate that!!

Found it bullseye!

I'm not sure what is your programming background

i used to deal with .asp programming so i have some background and i also watched lots of c++ tutorials so i already know some fundamentals!!
thx again dude !
best Regards
