Model->Release Crashes

[martyj]

On my demo map, the game crashes whenever I drop an item. (And only on this map).

 

I am on the Non-Beta branch.

 

Here is the crash I receive: http://imgur.com/a/oVIJL

 

Sample Code:

 

Creation

this->model = (Model*)Model::Load(item->GetModelPath(), Asset::Unmanaged);
this->model->SetUserData(this);
this->model->SetKeyValue("name", item->GetName());
this->model->SetVelocity(Vec3(0, 0, 0), true);
this->model->SetCollisionType(Collision::Prop);
this->model->SetPhysicsMode(Entity::RigidBodyPhysics);
this->model->SetPickMode(Entity::SpherePick, true);
this->model->SetMass(10); // TODO: real mass
this->model->SetSweptCollisionMode(true);
this->model->SetPosition(position, true);

 

Destroy Code

ItemEntity::~ItemEntity()
{
this->model->SetParent(NULL);
this->model->Hide(); // TODO: Delete me
this->model->SetUserData(NULL);
this->model->Release();
}

 

I can provide my full source code if needed.

That happens to me if I somehow use the model after I release it, even if I'd swear up and down that it's impossible. But if you're saying it doesn't happen on other maps then I'm not sure.

 

Also, not sure if you check elsewhere but you may consider checking if model==NULL (and setting it at the start and after release).

[martyj]

If you look at the stacktrace on the image, there is no way that I could use it after I release it as the exception is thrown in library code that is above my Release call in the stack. So it's somewhere in Leadwerks code that the crash happens, in the RemoveAll function.

[Undac]

Well, the Release() method works just fine for me, so I guess the problem is elsewhere.

Before you call the destructor, do you see the item in game? If you're not sure it does, the problem might be the attempt to Hide() an empty model. The error happens when you try to call the destructor or when you exit the map? If it happens when you exit the map, maybe you call delete world before the destructor of ItemEntity.

 

PS: I have no idea what Asset::Unmanaged is.

For something like this I definitely need the project so I can run the code and see.

[martyj]

My computer took a **** on me at the moment, I can get you GIT access right now,

 

or in a week I can get you a zip of the project.

[Josh]

A single zip file would be helpful. Thanks.

See PM with link and instructions on how to reproduce.

Any update to this? I know you're super busy with the new UI.

I might be running in to a similar problem only using Lua. I'll wait and see if this issue gets resolved to see if it fixes my problem to.

Working on this this week, along with a few other peoples' projects.
