problem with setSkyBox

[dowi]

hi

im working with ogre 1.8 branch (downloaded and compiled couple of days ago) on the iphone

i have a problem with SetSkyBox the second time i call it.

it crashes at

Code: Select all

Pass* pass = m->getBestTechnique()->getPass(0);

the call stack is :

Code: Select all

#0	0x008e586e in std::vector<Ogre::Pass*, Ogre::STLAllocator<Ogre::Pass*, Ogre::CategorisedAllocPolicy<(Ogre::MemoryCategory)0> > >::size() const at /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS5.0.sdk/usr/include/c++/4.2.1/bits/stl_vector.h:400

what can the problem be?
thanks allot!

Hi dowi,

did you get it working? If not, could you post a little of your code in OgreApp::SetSkyDome() and tell us what parameter values that SceneManager::setSkyDome() is receiving?

Thanks

Hi it's dowi.

Here is the SetSkyBox code:

Code: Select all

 void OgreApp::SetSkyBox(string skyBoxName)
{
    
    ScreenManager::GetInstancePtr()->ShowView(screenProgressEnum, "Loading...");
    
//    mSceneMgr->setSkyBoxEnabled(false);
//    mSceneMgr->setSkyBox(false, "");

    StringVector res = ResourceGroupManager::getSingleton().getResourceGroups();
    StringVector::iterator itr;
    for (itr = res.begin(); itr != res.end(); itr++)
    {
        ResourceGroupManager::getSingleton().unloadUnreferencedResourcesInGroup((*itr));
    }

    if (skyBoxName != "")
    {
        mSceneMgr->setSkyBox(true, skyBoxName, 5000, true);
    }

    ScreenManager::GetInstancePtr()->HideView(screenProgressEnum);
    
    //mSceneMgr->setSkyDome(true, skyBoxName, 5,60);  
}

Sorry, can't really help you, other than with an obvious guess:
- the name you are specifying is not a valid material name
- you are unloading the material before using it

I think it's unclear if m->getBestTechnique()->getPass(0) is asserting because the valid pointer m is a material with 0 Passes, or because m is an invalid pointer.

It works in 1.7.x?
Try the Help forum?
