is there any way i can get the vertex information from the mesh?

I have another question - what are the

csVector3 *       vertices,
int     num_vertices,

for in the arguments of Engine->CreatePortal()? also how do i get the number of vertices? is this something can get from the mesh?

regards,
Kate

hi there

I see how to create sectors, and specify the destination sector, but what about the actual destination position? How does the portal know where to position the player in the destination sector?

regards
Kate

ok - ive done this by using SetWarp();

thanks, that solved the problem

Kate

Do you have any coding experience? Have you tried reading the manual/compiling crystal space?

Hi there,

I have a problem which is that when I create an explosion, whatever texture I use just shows as black.

I am using the following code (using the explo texture from walktest)
There are no errors about the texture not being found, so I know its not that thats the problem :

Code:

  //Setup missile explosion ready for use
  csRef<iGeneralFactoryState> fstate;
  csRef<iEngine> engine = app->GetEngine();
  csRef<iLoader> loader = app->GetLoader();
 
  missile_explo_factory = engine->CreateMeshFactory ("crystalspace.mesh.object.explosion", "explosion");
  if (!missile_explo_factory)
  {
    app->ReportError("Failed to load explosion mesh factory!");
  }
 
  if (!loader->LoadTexture ("explosion_texture", "img/explo.jpg"))
  {
    app->ReportError("Error loading 'explo' texture!");
  }

  //Create it
  csRef<iMeshWrapper> explosion = app->GetEngine()->CreateMeshWrapper(missile_explo_factory, "explosion", sector, pos);
  if (!explosion)
  {
    app->ReportError("Error creating explosion mesh!");
    return;
  }
  explosion->SetZBufMode(CS_ZBUF_TEST);
  explosion->SetRenderPriority (app->GetEngine()->GetAlphaRenderPriority ());
   
csRef<iParticleState> partstate= scfQueryInterface<iParticleState>(explosion->GetMeshObject());

  csRef<iMaterialWrapper> mat = app->GetEngine()->GetMaterialList()->FindByName("explosion_texture");
  partstate->SetMaterialWrapper (mat);
  partstate->SetColor (csColor (1, 1, 0));
  partstate->SetChangeSize (1.25);
  partstate->SetSelfDestruct (3000);
  partstate->SetChangeRotation (5.0f);
  partstate->SetAlpha(0.5);

   csRef<iExplosionState> expstate (
  SCF_QUERY_INTERFACE (explosion->GetMeshObject (), iExplosionState));
  expstate->SetParticleCount (100);
  expstate->SetCenter (csVector3 (0, 0, 0));
  expstate->SetPush (csVector3 (0, 0, 0));
  expstate->SetNrSides (6);
  expstate->SetPartRadius (0.15f);
  expstate->SetLighting (false);
  expstate->SetSpreadPos (0.6f);
  expstate->SetSpreadSpeed (2.0f);
  expstate->SetSpreadAcceleration (2.0f);
  expstate->SetFadeSprites (500);
  explosion->PlaceMesh ();

has anyone else managed to get a joystick working? please let me know if you have

Bo Hannon says get nerdling to do it

any clues?

thanks, Kate

Hi there,

Up until now I have just had ambient lighting for my map.

I tried doing:
    csRef<iLight> light = engine->CreateLight("DynLight", csVector3(-19, 120, 34), 300, csColor(1, 1, 1));
    if(!light)
    {
        app->ReportError("Failed to create light!");
    }
    levelsector->GetLights()->Add(light);

This works fine on an untextured map (where textures get replaced with the checkerboard) , but causes a segfault when I use the textured map.

It is the

 levelsector->GetLights()->Add(light);

line that causes the segfault. Valgrind debugger gives me the following:

==28337== Process terminating with default action of signal 11 (SIGSEGV)

It looks like a null pointer problem at : CastShadows_Front2Back(csKDTree*, void*, unsigned, unsigned&) (in /home/kate/csinstall/lib/crystalspace/frustvis.so)

any ideas what is causing this. Im assuming it is something to do with the textures but what? Could missing/wrongly applied textures cause the problem?

just to add that my ./compile does find a linux joystick api, but joytest still cant load the plugin

Kate

Hi there

I want to use a joystick with my game,

When I run the joytest app provided with CS I get:
failed to initialise plugin: crystalspace.device.joystick.linux

Do I need something specific installed for joystick support?

Kate Mallichan

the force is simply an int value, not a vector. is this where i am going wrong?

I am using the following code:

    car->AddRelForce(CS_VEC_FORWARD*acceleration_force);
    car->Update();

The problem is that the force seems to be applied along the nearest world axis, so that the car veers towards the axes
when it is supposed to be moving forwards in the direction is is pointing. I think I may have to do something with car->GetOrientation() but I am not sure what. I would appreciate any help you can give as this is becoming an urgent situation with a project deadline coming up!

thankyou for your help,

Kate Mallichan

Hi there,

I'm thinking of submitting a Summer of Code application.
I'd like to know who I need to send this to?
