learned two new things about VFS today

one
     you can use the  vfh[exe] program from cs to browes you VFS setup, copy it to your application directory and run it.

two
    when using
                // Load application-specific configuration file.
              if (!csInitializer::SetupConfigManager(r,
                                "/this/vfs.cfg", GetApplicationName()) )

the file must be called "vfs.cfg" or any mount commands in the cfg file will not work !!!!

regards

Just though i would post a link to this page

http://www.network-theory.co.uk/gcc/intro/

as I struggled with GCC setup and found it very hard to find the answers to question regarding using GCC.
so if you want to know why you lib's are not linking and what to do about it read this.

I created a world.zip file for walktest.

Get different problems but probably the same cause. I created a sphere and a plane at (0,0,0) and (0,100500,0) , the meshes at (0,0,0) work as expected, but the meshes at (0,100500,0) dont seem to be visiable or working with the collision detection.

File can be DL from

http://www.uploading.com/files/Z38R0FY5/world.zip.html

there are 2 camera positions, camera position works ok, camera2 and you are falling through darkness.

If some else  could try this out and see if it's a local problem or something more general I would be very happy

Renderloop ? Dont know, what exactly is the render loop?.
Shaders? Dont think i am using any shaders.

Sorry I cant give much info as i have not really gotten that far into CS. It's a very basic setup, Basicly Load a bunch of pluging and a nearly empty world XML file. then it adds the meshes and the light. The meshes are there and are easly seen if they are less that 100500 from the light.

I will try recreate the behavior using a simple XML world file and walktest and post it somewhere.

regards

Hi,
   I created a light using

  csRef<iLight> light;
  iLightList* ll = room->GetLights ();

  light = engine->CreateLight(0, csVector3( 0, 0, 0), 1000000, csColor(1, 1, 1));
  ll->Add (light);

and created a bunch of sphere's using

csRef<iMeshWrapper> mesh (engine->CreateMeshWrapper (ballFact, "ball", room));

the sphere's are

   createsphere( "100000" , radius, center, "grid.jpg" , csVector3 (100000,0,0) );
   createsphere( "100250" , radius, center, "grid.jpg" , csVector3 (100250,0,0) );
   createsphere( "100500" , radius, center, "grid.jpg" , csVector3 (100500,0,0) );
   createsphere( "100700" , radius, center, "grid.jpg" , csVector3 (100700,0,0) );
   createsphere( "101000" , radius, center, "grid.jpg" , csVector3 (101000,0,0) );

   createsphere( "146000" , radius, center, "grid.jpg" , csVector3 (146000,0,0) );

The problem is that after the 100500 sphere the ligh only seems to work if camera can see the light.
say i am at 109000,0,0 looking at a sphere it's totaly black, but if i move the camera to 101100, 500, 0 and look back to 0,0,0 I can see the sphere.

is this expected behavior?

Well you need to give more information when you ask a question, saying it dont work is not the way to go.

have you tried

To compile Crystal Space, you'll have to perform the following steps. If anything doesn't work, see the Win32 FAQ, MSVC7 FAQ.

   1. Load `CS\mk\msvc\wkstypical.sln'.
   2. From the file menu select Build->Build Solution. Note: If you want to build a debuggable version of Crystal Space, you should select the Debug build mode; otherwise select the Release build mode. Do not use the special-purpose ExtensiveMemDebug build mode.
   3. After a while the compilation should finish. The signal for a successful build will be come in the form of the something similar to the following:
          

      Build: 1 succeeded, 0 failed, 0 skipped

and if so what went wrong.
did you down load the CS code, and where did you install it? what version? can you find the file "wkstypical.sln"? if not does it exist? if so is you file open dialog giving you the option of opening a .sin file? ect...

Give as much detail as you can and you will get more help.

I dont use windows so I cannot really help you much.

can only suggest you write a long post detailing everthing and at what point the instructions stop working

took me about a day to get CS working, linux dependancy hell , but it can be done in both linux and win, you just missing somthing simple.

regards and good luck

Well the problem was with my ODE ./configure line

was

./configure --enable-double-precision --with-opcode --enable-debug --with-cylinder --prefix=$HOME/development/output

had to take out the --enable-double-precision bit ( 32 bit computer i guess )

./configure --enable-debug --with-cylinder --prefix=$HOME/development/output

then after recompiling ODE/CS then error went away.

Thx  for the help Jorrit.

well figured out my problem.
The mesh I am tring to rotate the same as the camera is a child mesh. So if i set the child mesh with the rotation of the camera is does not take into account the rotation of the parent mesh.

So I am thinking the smart thing to do is rotate the mesh and make the camera match. Might still have the same problem.
So a question, how do you sum 2 csMatrix3 rotation?


 

Well I installed the CG shader lib then linked and compiled CS. the sharder not loading message is gone.
The ./walktest stenciltest still gives me a black screen. not sure what it's meant to look like.

got the CG lib at
http://developer.nvidia.com/object/cg_toolkit.html

Using very recent rev's of CS/CEL/ODE and started getting this error running wheeledtest.

Anyone else getting this?

Been trying to do this for a while now.
I want to move the camera to the position of a mesh and then rotate the mesh the same as the camera.
For some reason the mesh rotates in the opposite direction to the camera. This worked fine with a normal mesh, don't seem to work with a child mesh.

Here is some code so you can see what i am trying

Code:

void AppSol::ProcessFrame()
{
csVector3 start, end;
   iMovable* movable ;
csReversibleTransform pot;
csMatrix3 rot;

  if (g3d->BeginDraw(engine->GetBeginDrawFlags() | CSDRAW_3DGRAPHICS))
  {
// First get elapsed time from the virtual clock.
csTicks elapsed_time = vc->GetElapsedTicks ();
// Now rotate the camera according to keyboard state
float speed = (elapsed_time / 1000.0) * (0.06 * 20);

iCamera* c = view->GetCamera();

if (kbd->GetKeyState (CSKEY_SHIFT))
  {
    // If the user is holding down shift, the arrow keys will cause
    // the camera to strafe up, down, left or right from it's
    // current position.
    if (kbd->GetKeyState (CSKEY_RIGHT))
      c->Move (CS_VEC_RIGHT * 4 * speed);
    if (kbd->GetKeyState (CSKEY_LEFT))
      c->Move (CS_VEC_LEFT * 4 * speed);
    if (kbd->GetKeyState (CSKEY_UP))
      c->Move (CS_VEC_UP * 4 * speed);
    if (kbd->GetKeyState (CSKEY_DOWN))
      c->Move (CS_VEC_DOWN * 4 * speed);
  }
  else
  {

               if (kbd->GetKeyState (CSKEY_RIGHT))
c->GetTransform().RotateThis(CS_VEC_ROT_RIGHT, speed);
if (kbd->GetKeyState (CSKEY_LEFT))
c->GetTransform().RotateThis(CS_VEC_ROT_LEFT, speed);
       if (kbd->GetKeyState (CSKEY_PGUP))
c->GetTransform().RotateThis(CS_VEC_TILT_UP, speed);
if (kbd->GetKeyState (CSKEY_PGDN))
c->GetTransform().RotateThis(CS_VEC_TILT_DOWN, speed);


if (kbd->GetKeyState (CSKEY_UP))
c->Move (CS_VEC_FORWARD * 4 * speed);
if (kbd->GetKeyState (CSKEY_DOWN))
c->Move (CS_VEC_BACKWARD * 4 * speed);

if (kbd->GetKeyState (CSKEY_F1)) {
// set camera to position.001
// Set controll to turret
PlayerMeshName = "trader";
PlayerCrewPos = "turret.001";
playermesh = engine->FindMeshObject ( "trader" , 0 );

aChildren = playermesh->QuerySceneNode()->GetChildrenArray ();
playermesh = aChildren->Top()->QueryMesh();
movable = playermesh->GetMovable ();

// get mesh's transform and move camera
pot = movable->GetFullTransform();
c->SetTransform (pot);
                           } //end if select turret
  }// end if key press


                       // It's a turret position, only change the rotation
       // Position our playermesh the same as camera
    movable = playermesh->GetMovable ();
end = movable->GetTransform().GetOrigin (); // want this mesh to say at it's current loc
rot = c->GetTransform().GetT2O();                         
csOrthoTransform pot ( rot, end);
              movable->SetTransform (pot);

// update player mesh in egin world space
movable->UpdateMove ();



// Tell 3D driver we're going to display 3D things.
if (!g3d->BeginDraw (engine->GetBeginDrawFlags () | CSDRAW_3DGRAPHICS))
  return;

// Tell the camera to render into the frame buffer.
view->Draw ();
}
}

I took out some code to make it clearer what i am doing. Seems to me only explanation is that my mesh is upside down in relation to the camera. But I made the transforms the same?

any suggestions as to what i am doing wrong?

thx

basicly a black screen when i run

 ./walktest stenciltest

and in about ever other CS app i run it says

 could not load plugin 'crystalspace.graphics3d.shader.glcg'

But other than that everything seem to be working.

want to find out why my shader is not working

I got a GeForce 6600 LE running on ubuntu6.06 with Nvidia linux Drivers loaded.
was wondering if it's the card, driver or OS set up causing the problem.
just an anoyance at the moment but I will have to try fix it eventualy

Just want to make this a more positave post.

My problem with VFS was it's like a black hole. In that stuff goes in but never comes out.
As it's the first thing any beginner is going to have to deal with I found the doc's lacked some simple example code to help. Spend a long time looking at segment faults not knowing if the VFS had mounted my files or not. Alter a long time i looking I found a list function in viewtest. As soon as i could see directly what was in VFS things got so much easer.


 // Print out dirs list
   printf ("Dirs\n");
   csRef<iStringArray> dirs = VFS->GetMounts ();
   for (i=0; i < dirs->GetSize(); i++)   
   printf ("%s \n", dirs->Get(i));   
   printf ("\n");

   VFS->ChDir ("/solworld/factories");
  // Print out dir-contents
   printf ("Files\n");
   csRef<iStringArray> files = VFS->FindFiles ("*");
   for (i=0; i < files->GetSize(); i++)   
       printf ("%s \n", files->Get(i));   
   printf ("\n");

this little piece of code did more for me that all the doc's on the VFS system.

Regards, VFS works it just hard to tell when it's working and what is in it.

I have been tying to work backwards from a mesh's Transform matrix to work out what the mesh's rotation is in radians. Not having much luck.

Here is a bit of code i was trying but it only worked for some angles and i not smart enough to workout what to do next


...........
   playermesh = engine->FindMeshObject ( "turret.001" , 0 );
   movable = playermesh->GetMovable ();
   // Get mesh Position
   start = movable->GetTransform().GetOrigin ();
   // get mesh Rotation
   pot = movable->GetTransform();

   rotX = getM3xAngle(pot);
   rotY = getM3YAngle(pot);
........


float AppSol::getM3xAngle ( csMatrix3 m3 )
{
//Rotation along the X-axis is represented by:
/// 1   0        0       \
//| 0   cos(a)   -sin(a) |
//\ 0   sin(a)   cos(a)  /
return  acos( m3.m22 );     
}
float AppSol::getM3yAngle ( csMatrix3 m3 )
{
//Rotation along the Y-axis is represented by:
/// cos(a)   0    -sin(a) \
//| 0        1    0       |
//\ sin(a)   0    cos(a)  /
return acos( m3.m11 );     
}

obviously, this does not work but my trig not that good and I cannot work out how to do this.
any help welcome.

Regards
