[Solved] OGRE3DBody Crash on update

Hey,

We are currently having a crash for any player that is online after a player leaves the game,

NxOgre Revision ( current 7/10/09 http://github.com/betajaen/nxogre )
Ogre 1.6.3

Here is the stack:

Player.exe!OGRE3DBody::advance(float __formal=0.023000000, float __formal=0.023000000) Line 124 + 0x51 bytes C++
NxOgre_Debug.dll!NxOgre::TimeController::_literal(float user_deltaTime=0.023000000) Line 115 + 0x25 bytes C++
NxOgre_Debug.dll!NxOgre::TimeController::advance(float deltaTime=0.023000000) Line 70 + 0x14 bytes C++
Player.exe!WorldState::update(float deltaTimeSecs=0.018999999) Line 213 + 0x18 bytes C++
Player.exe!Application::update() Line 96 + 0x1e bytes C++
Player.exe!main() Line 12 + 0x1e bytes C++
Player.exe!__tmainCRTStartup() Line 586 + 0x19 bytes C
Player.exe!mainCRTStartup() Line 403 C



Extra Information:
For our world(WorldState) when a player joins it creates an actor.
In our actor on initialisation we create our OGRE3DBody:

Header
// NxOgre Actor Body
OGRE3DBody* physicsBody;)

Source:
NxOgre::RigidBodyDescription desc;
desc.mBodyFlags |= NxOgre::Enums::BodyFlags_FreezeRotation;
desc.mMass = 0.5f;
desc.mMaxAngularVelocity = 5;

// init the physics body using the scene node
physicsBody = renderSystem->createBody( new NxOgre::Capsule( 5, 20 ), NxOgre::Functions::XYZ<Ogre::Vector3, NxOgre::Vec3>(position), baseNode, desc );


When any player leaves the onPlayerExit function is called and removes that player(actor) from the game.
This is in WorldState:
Source:
std::map<unsigned short, Actor*>::iterator i = actors.find(playerNetID);

if (i != actors.end())
{
// Remove the actor for the player that has just exited
Actor* actor = (*i).second;
chatConsole->addText("'" + actor->getTitle() + "' has left the world.");

delete actor;
actors.erase(i);

this->updatePlayerList();
}

The crash starts (as you can see above in the stack) when the advance is called for the Physics.
pTimeController->advance( NxOgre::Real( nxOgreTimer ));

It tries to set the position of the OGRE3DBody that now doesn't exist and hence the crash.

Any work arounds? or fixes?

Thanks

You can't just delete the Actor. Use this method instead to properly get rid of the whole OGRE3DBody (so the Actor and its visualization):
mRenderSystem->destroyBody(m_physicsBody);

Worked! !

Thanks so much
