pure virtual method called

[zamme]

Hi all.

A problem with regions unloading.
When the player pass through a portal, CS crashes when it try to unload a region
or load the next one (I don't know exactly when to).

error message:
pure virtual method called
terminate called without an active exception

BT:
Program received signal SIGABRT, Aborted.

Can it be from not attached meshes?


Thank you.

Hello,

  it's a bit hard to find out, without code nor data.
Do you use CEL zone manager system with zones ?

[zamme]

Hi Vincent.

Yes. I didn't put code because using the zonemager.
I will try to attach all the entities and meshes to regions before zonemanager unloads them.
Is possible that zonemanager crashes when it try to unload not attached meshes?

Thanks.

P.S.: Do you remember when we talk about uvanim and animated texture, on the IRC?
I've tried uvanim with billboards but it doesn't works. It's only for meshes.

[zamme]

Ok.
I attached all the entities and the "pure virtual method called" error has disappeared.
Now it crashes in:

Program received signal SIGSEGV, Segmentation fault.

I haven't included iengine/viscull.h. iVisibilityCuller depends on it. Is it the problem?

[Vincent]

Can you attach an archive with code & data so we can try to reproduce that ?
Also, which CS & CEL version/revision do you use ?

[zamme]

Hi Vincent.

Svn:
https://opensvn.csie.org/svmres/trunk/

There is much code.
Look for world_Estabulari, at "Debug/data/level1/" directory.
The problem is when the zonemanager unloads the world_Estabulari region.

All is managed by the Zonemanager.
Is better to manage them manually?
I'm thinking to make it all whithout the zonemanager.

Thanks.

[zamme]

Sorry, Vincent.

CS trunk revision 32697.
CEL trunk revision 3929.

See you.
