Shit! iPcLinearMovement::InitCD() didn`t work.

It works well on player (player entity can collide with other entities (their meshes loaded using <meshobj/>), except CrystalAlpha):
player_entity = pl->CreateEntity ("player", bl, "player_behave",
    "pccamera.old",
    "pcobject.mesh",
    "pcmove.linear",
    "pcmove.actor.standard",
    "pcinput.standard",
    "pcsound.listener",
    "pctools.inventory",
    CEL_PROPCLASS_END);
  if (!player_entity)
    return ReportError ("Error creating player entity!");

........................

  csRef<iPcZoneManager> pczonemgr = CEL_QUERY_PROPCLASS_ENT (
        level_entity, iPcZoneManager);

  // Get iPcCamera interface
  csRef<iPcCamera> pccamera = CEL_QUERY_PROPCLASS_ENT (player_entity, iPcCamera);

  // Get the iPcMesh interface so we can create the right mesh
  // for our player.


  csRef<iPcMesh> pcmesh = CEL_QUERY_PROPCLASS_ENT (
        player_entity, iPcMesh);
  csBox3 team_box (csVector3 (0.7f, 1.5f, 0.5f));
  pcmesh->CreateNullMesh ("team_mesh", team_box);
    if (!pcmesh->GetMesh ())
    return ReportError ("Error loading model!");

  scfString regionname, startname;
  pczonemgr->GetLastStartLocation (&regionname, &startname);
  // Put player into the world
  pccamera->SetZoneManager (pczonemgr, true, regionname, startname);

  // Set mesh to start position
  if (pczonemgr->PointMesh ("player", regionname, "Spawn"))
    return ReportError ("Can't find region or start position in region!");

  // Get iPcLinearMovement so we can setup the movement system.
  csRef<iPcLinearMovement> pclinmove = CEL_QUERY_PROPCLASS_ENT (
        player_entity, iPcLinearMovement);
  pclinmove->InitCD (
     csVector3 (0.8f,0.8f,0.5f),
     csVector3 (0.6f,0.7f,0.5f),
     csVector3 (0,0,0));

  // Get the iPcActorMove interface so that we can set some parameters
  csRef<iPcActorMove> pcactormove = CEL_QUERY_PROPCLASS_ENT (
        player_entity, iPcActorMove);
  ------------------------


But it`s not work on other entities (CrystalAlpha, for example):
BehaviourItem::BehaviourItem (iCelEntity* entity, ProjectBL* bl, iCelPlLayer* pl)
    : BehaviourCommon (entity, bl, pl)
{
  GetMeshSelect();
  if (mesh_select)
  {
    mesh_select->SetMouseButtons("r");
    csRef<iPcCamera> player_camera = CEL_QUERY_PROPCLASS_ENT (
          pl->FindEntity("player"), iPcCamera);
    mesh_select->SetCamera(player_camera);
    mesh_select->SetMaxSelectionDistance (1.5f);
  }
  pcmeshsel_down_id = pl->FetchStringID ("pcmeshsel_down");

  // Test lines
  csRef<iPcLinearMovement> linmov = CEL_QUERY_PROPCLASS_ENT (entity, iPcLinearMovement);
  if (linmov) linmov->InitCD (csVector3 (0.7f, 0.35f, 0.7f),
                csVector3 (0.7f, 0.35f, 0.7f), csVector3 (0.0f, 0.0f, 0.0f));
}

Yes. I write that:

BehaviourItem::BehaviourItem (iCelEntity* entity, ProjectBL* bl, iCelPlLayer* pl)
    : BehaviourCommon (entity, bl, pl)
{
  ..........................
  csRef<iPcLinearMovement> linmov = CEL_QUERY_PROPCLASS_ENT (entity, iPcLinearMovement);
  linmov->InitCD (csVector3(xb, yb, zb), csVector3(xl, yl, zl), csVector3(0, 0, 0));

Hi.

Yep, I write it by hand. But as I said before, walk tutorial doesn`t detect collides with entities too. Also I added "offset" to "InitCD" action and changed "vector3" to "vector" (it is the same) but nothing changes. I think, I have not any dependences, that is needed to do collision detection, but I don`t know what it can be. Is it possible to do collision detection with bullet?

Hi there!

I have a problem with "InitCD" action in "pcmove.linear" property class.

I try to initialize collision detection via "InitCD" action but collision detection doesn`t work.
My entity from xml file:
  <addon entityname="CrystalAlpha" plugin="cel.addons.celentity">
      <propclass name="pcobject.mesh">
        <action name="LoadMeshPath">
          <par string="/mydata/worlds/planetcontrolcenter/factories" name="path"/>
          <par string="Crystal" name="filename"/>
          <par string="Crystal" name="factoryname"/>
        </action>
      </propclass>
      <propclass name="pcobject.mesh.select"/>
      <propclass name="pctools.properties">
        <property name="ITEM" bool="yes"/>
        <!--<property name="NPC" bool="no"/>-->
      </propclass>
      <propclass name="pcmove.linear">
        <action name="SetPosition">
           <par string="Scene" name="sector"/>
           <par name="yrot" float="0"/>
           <par name="position" vector3="1,1,1"/>
        </action>
        <action name="InitCD">
          <par name="body" vector3="0.7,0.35,0.7"/>
          <par name="legs" vector3="0.7,0.35,0.7"/>
        </action>
      </propclass>
      <behaviour name="item_behave"/>
    </addon>
Result is properly loaded and properly located mesh but without collision detection. If I place mesh into the world with <meshobj/> from <sector/> section or invoke iPcLinearMovement::InitCD from c++ code collision detection works ok.

Another strange thing is that collision detection don`t work with entities from WALKTUT but collision detection works well with walls and floor.
I build crystal space with ODE with OPCODE support, but without bullet.
Is my problem in dependences? Or maybe I do something wrong in describing "pcmove.linear" property class? Why Walktut doen`t work? Please help me.

Thanks, Zuck.

Unfortunately, I can`t provide buildable variant because it have size of 180MB and because of strange promblem with forum: I can`t upload anything. I think all I can to do, it is give you some pieces of code if you need.

NB:Last post I forgot say you that I set up sound listener properly: it always follows the player mesh.

I can`t play sounds in Crystal Space using CEL. First I attach all needed plugins.
Second I load my sound wrapper.

CsRef<iLoader> loader;
CsRef<iSndSysRenderer> sndrdr;
CsRef<iSndSysManager> sndmgr;
CsRef<iCelPlLayer> pl;
CsRef <MyBehaviourLayer> bl;
....
loader->LoadSoundWrapper ("background", "/mydata/music/tarck02.ogg");

Third, I create music playing entity:

pl->CreateEntity ("music_player", bl, "item", "pcsound.source", CEL_PROPCLASS_END);
csRef<iPcSoundSource> bgsound_source = CEL_QUERY_PROPCLASS_ENT (pl->FindEntity ("music_player"), iPcSoundSource);

Fourth, play sound

bgsound_source->SetSoundName ("background");
bgsound_source->GetSoundSource()->SetVolume (1.0f);
bgsound_source->GetSoundSource()->GetStream()->SetLoopState (
                CS_SNDSYS_STREAM_LOOP);
bgsound_source->GetSoundSource()->GetStream()->Unpause();

On string "bgsound_source->GetSoundSource()->SetVolume (1.0f);" my game crashes.

I can play sounds with iSysSndRenderer and iSysSndManager:
csRef<iSndSysStream> stream = sndrdr->CreateStream (
      sndmgr->FindSoundByName ("background")->GetData(), CS_SND3D_DISABLE);
csRef<iSndSysSource> source = sndrdr->CreateSource (stream);
source->SetVolume(1.0f);
stream->Unpause();
All works perfect, but I want play sounds using CEL. What I am doing wrong? Please help me to learn how to create playable sound source using sound wrappers and CEL.

Ya, I install Crystal Space into /opt/crystalspace because of large size of build directory. I made patch (for Gnu patch/Gnu diff) for crystal2blender from current svn revision. All works good.

Help me here
http://www.crystalspace3d.org/forum/index.php/topic,1625.0.html

I download crystal2blender and have some problems. When I want to export my mesh into crystal space format, i got "E: Make sure you set your CRYSTAL environment variable before loading blender" error.

I was trying to launch blender this way (I use Linux):
> CRYSTAL=/opt/crystalspace (path to crystal space)
> export CRYSTAL
> blender

but i still get this message. What is wrong?          Sorry for bad English
