Setting a parent scene node 0.9 & crash on scene manager

cartoonit · Post by **cartoonit** » Fri Apr 08, 2005 7:54 am

I've just ported to 0.9 and included some of my updates, I haven't changed any of my code within my application, but whenever I try to show my weapon the application crashes on the scene manager. The weapon scene node is definately loaded, I don't really understand why it would crash now??? I'm just setting the weapon scene node to be the child of the camera fps node...

Difficult to say. Could you debug it and tell us exactly where it crashes?

I've just changed back to 0.8, gotta hand this in soon, so I'll try again with 0.9 after its been given in.

Its saying that it can't read memory address 0x000005, as far as I can remember on the mp_Smgr->drawAll();... I set the child of the fps camera to be the weapon, and then set it visible and crash... I'll have a further look if I get some time soon, but I don't really use any of the new 0.9 features yet...

I changed some things with parent handling in 0.9. Ususally this should prevent some crashes. Are you sure you didn't delete the parent of the child scene node or something? Because it looks like it tries to get something (I guess the absolute position) from its parent, but hasn't any access to it anymore.
But I'm checking out if I made an error somewhere.

It sounds like a bug I fixed recently where I was calling 'drop' on GUI objects (rather than 'remove') --- after which, a call to m_env->draw would crash the app.

I second Niko's suggestion that maybe you're deleting a scene node rather than properly removing it from the scene graph.
