What does this error mean?

[FSA]

Error is happening here. Before that code matrix is ok. After it some strange values in matrix.

Code: Select all

// integrate linear velocity
   dFloat normalizedTimeLeft = 1.0f;
   dFloat step = timestep * dSqrt (veloc % veloc) ;
   dFloat descreteTimeStep = timestep * (1.0f / D_DESCRETE_MOTION_STEPS);
   int prevContactCount = 0;
   CustomControllerFilterCastFilter castFilterData (body);
   NewtonWorldConvexCastReturnInfo prevInfo[PLAYER_CONTROLLER_MAX_CONTACTS];
   for (int i = 0; (i < D_PLAYER_MAX_INTERGRATION_STEPS) && (normalizedTimeLeft > 1.0e-5f); i ++ ) {
      if ((veloc % veloc) < 1.0e-5f) {
         break;
      }

      dFloat timetoImpact;
      NewtonWorldConvexCastReturnInfo info[PLAYER_CONTROLLER_MAX_CONTACTS];
      dVector destPosit (matrix.m_posit + veloc.Scale (timestep));
      int contactCount = NewtonWorldConvexCast (world, &matrix[0][0], &destPosit[0], m_collisionShape, &timetoImpact, &castFilterData, CustomControllerFilterCastFilter::ConvexStaticCastPrefilter, info, sizeof (info) / sizeof (info[0]), threadIndex);
      if (contactCount) {
         contactCount = manager->ProcessContacts (this, info, contactCount);
      }

      if (contactCount) {
         if (timetoImpact > 0.0f) {
            matrix.m_posit += veloc.Scale (timetoImpact * timestep);
         }
         normalizedTimeLeft -= timetoImpact;

         dFloat speed[PLAYER_CONTROLLER_MAX_CONTACTS * 2];
         dFloat bounceSpeed[PLAYER_CONTROLLER_MAX_CONTACTS * 2];
         dVector bounceNormal[PLAYER_CONTROLLER_MAX_CONTACTS * 2];

         int count = 0;
         const dFloat restitution = 0.0f;
         for (int i = 0; i < contactCount; i ++) {
            speed[count] = 0.0f;
            bounceNormal[count] = info[i].m_normal;
            dFloat reboundVelocMag = -(veloc % bounceNormal[count]) * (1.0f + restitution);
            bounceSpeed[count] = (reboundVelocMag > 0.0f) ? reboundVelocMag : 0.0f;
            count ++;
         }

         for (int i = 0; i < prevContactCount; i ++) {
            speed[count] = 0.0f;
            bounceNormal[count] = prevInfo[i].m_normal;
            dFloat reboundVeloc = (veloc % bounceNormal[count]) * (1.0f + restitution);
            bounceSpeed[count] = (reboundVeloc > 0.0f) ? reboundVeloc : 0.0f;
            count ++;
         }

         dFloat residual = 10.0f;
         dVector auxBounceVeloc (0.0f, 0.0f, 0.0f, 0.0f);
         for (int i = 0; (i < D_PLAYER_MAX_SOLVER_ITERATIONS) && (residual > 1.0e-3f); i ++) {
            residual = 0.0f;
            for (int k = 0; k < count; k ++) {
               dFloat v = bounceSpeed[k] - bounceNormal[k] % auxBounceVeloc;
               dFloat x = speed[k] + v;
               if (x < 0.0f) {
                  v = 0.0f;
                  x = 0.0f;
               }

               if (dAbs (v) > residual) {
                  residual = dAbs (v);
               }

               auxBounceVeloc += bounceNormal[k].Scale (x - speed[k]);
               speed[k] = x;
            }
         }

         dVector velocStep (0.0f, 0.0f, 0.0f, 0.0f);
         for (int i = 0; i < count; i ++) {
            velocStep += bounceNormal[i].Scale (speed[i]);
         }
         veloc += velocStep;

         dFloat velocMag2 = velocStep % velocStep;
         if (velocMag2 < 1.0e-6f) {
            dFloat advanceTime = dMin (descreteTimeStep, normalizedTimeLeft * timestep);
            matrix.m_posit += veloc.Scale (advanceTime);
            normalizedTimeLeft -= advanceTime / timestep;
         }


         prevContactCount = contactCount;
         memcpy (prevInfo, info, prevContactCount * sizeof (NewtonWorldConvexCastReturnInfo));

      } else {
         matrix.m_posit = destPosit;
         matrix.m_posit.m_w = 1.0f;
         break;
      }
   }


I will try to find the position in the code exactlier.

So I get the Error. It's a fault by newton I think. In function

Code: Select all

void CustomPlayerController::PostUpdate(dFloat timestep, int threadIndex)

Code: Select all

NewtonBodyGetVelocity(body, &veloc[0]);

returns some very high values (e+12). I have test in in first frame the function runs. So logical the next functions will use the velocity like:

Code: Select all

dVector destPosit (matrix.m_posit + veloc.Scale (timestep));

and then the matrix is very strange.

Debug code:

Code: Select all


BODY VELOC
5.23636e+012
-1.33333
8.51689e+013

Matrix.m_posit BEFORE USE VELOC
-25
30
0

Matrix.m_posit AFTER USE VELOC
5.23636e+009
29.9987
8.51689e+010


So the error is the velocity.

in function PostUpdate, veloc is adjiste each time a collsion happens, tray to trace teh values of step, to see if somethong is going wrondg there
thishappen here

Code: Select all

         dFloat residual = 10.0f;
         dVector auxBounceVeloc (0.0f, 0.0f, 0.0f, 0.0f);
         for (int i = 0; (i < D_PLAYER_MAX_SOLVER_ITERATIONS) && (residual > 1.0e-3f); i ++) {
            residual = 0.0f;
            for (int k = 0; k < count; k ++) {
               dFloat v = bounceSpeed[k] - bounceNormal[k] % auxBounceVeloc;
               dFloat x = speed[k] + v;
               if (x < 0.0f) {
                  v = 0.0f;
                  x = 0.0f;
               }

               if (dAbs (v) > residual) {
                  residual = dAbs (v);
               }

// HERE trace  valee of x and auxBounceVeloc, I think something can go wrong in the solve
               auxBounceVeloc += bounceNormal[k].Scale (x - speed[k]);
               speed[k] = x;
            }
         }

         dVector velocStep (0.0f, 0.0f, 0.0f, 0.0f);
         for (int i = 0; i < count; i ++) {
            velocStep += bounceNormal[i].Scale (speed[i]);
         }
         veloc += velocStep;

[Julio Jerez]

tell something do this happens in teh test that you sent me?

[FSA]

Can't find the code. And I also dont really now what you mean

[FSA]

No i gave you the debug build. There all works fine.

[Julio Jerez]

not give me a release build, It does not help me if teh bug do no happens.
I cna run debug dlls in a release buidl, but I can not run teh opsite will no help if teh bug do n happens.

maybe give two exe, one in debug and one in release.

[FSA]

You cant really see the bug. Only the player fly at very high spedd threw th world Wait i upload it. I give you the source with it.

[Julio Jerez]

But how do you make it happens. i soudl eb able to do it too.
I do not need the source I only nee to know how to make happen.

can you just put teh release and debug in the archive? I cna debug like that.

[FSA]

I made a SVN-checkout and no nothing compiles anymore
unresolved external symbol ""private: static class dRtti CustomControllerBase::m_rtti" (?m_rtti@CustomControllerBase@@0VdRtti@@A)".
I have that error meanwhile.

To create the bug i do nothing. Right after the start of the program the player fly's away.

[Julio Jerez]

did we solved the m_rrti bug, I am totally confused now.

[FSA]

Yes but after the checkout, it comes up against. I've make everyrhing like before. Build build.sln buil newton.sln ovverwrite libaries, add JointLibary to my project. Something is really wrong

[Julio Jerez]

In source controll look at the history of this file: c:..\packages\dContainers\dRtti.h
you will see that is used to have a base class, and now is a full macro, therefore all instances of m_rtti are pat of the leaf class and should have dll declaration.

edit:
I delete the other post

I do not know what could be wrong has you build the joint library before or were you using the precompile one?
make sure this define JOINTLIBRARY_EXPORTS if set if you build the DLL.

[FSA]

So i got it now. After a second svn checkout everthing is fine, and i don't must include the joinlibary into my project.
Here is the link to the relase build: https://www.dropbox.com/s/hcgjslimgb0km ... _Julio.zip
The Bug happens right after the start. The Position is 1|1|1 but the matrix say 1.#IO 1.#IO 1.#IO
Sometimes it's 1.#IO an sometime some very high values.
Hope you can find the bug

[Julio Jerez]

Oh very well, I will get that tonight an debug it.

will also add the pley avility to be push around by moving bodies, which still does not do now.

for example a tank hitting you, it sodu mush you away,
you jumping of the hull of a vehicle, or on top of a platform, the player should inherit the velocity of the floor, and it can even have friction.
