Ray cast and joint library.dll crash !

[izissise]

Hello,

I have some problem with ray cast , it grab well, but when i release the joint sometime joint library.dll crash !maybe because newtonupdate is in another thread....

Here my code :

To pick :

Code: Select all

///variable globale pour les fonction de picking
static NewtonBody* pickedBody = NULL;
static CPhysique* class_body = NULL;

static float pickedParam = 1.0f;
static dVector rayLocalNormal;
static bool isPickedBodyDynamics;
static dVector attachmentPoint;
static NewtonUserJoint* bodyPickController;
static bool mousePickMode = false;
///


CPhysique* MousePick(NewtonWorld* nWorld,int x,int y,bool create_joint)
{


    dVector p0 (ScreenToWorld(dVector (x, y, 0.0f, 0.0f)));
    dVector p1 (ScreenToWorld(dVector (x, y, 1.0f, 0.0f)));


    class_body = NULL;

    NewtonWorldRayCast(nWorld, &p0[0], &p1[0], RayCastFilter, NULL, get_pointeur_class); //raycastfilter nous donne le body


    if (pickedBody&&create_joint)
    {
        dMatrix matrix;

        mousePickMode = true;

        NewtonBodyGetMatrix(pickedBody, &matrix[0][0]);
        dVector p (p0 + (p1 - p0).Scale (pickedParam));

        attachmentPoint = matrix.UntransformVector (p);

        // convert normal to local space
        rayLocalNormal = matrix.UnrotateVector(rayLocalNormal);

        // Create PickBody Joint
        bodyPickController = CreateCustomKinematicController (pickedBody, &p[0]);

        CustomKinematicControllerSetPickMode (bodyPickController, 1);
        CustomKinematicControllerSetMaxAngularFriction (bodyPickController, MAX_FRICTION_ANGULAR_GRAVITY);
        CustomKinematicControllerSetMaxLinearFriction (bodyPickController, MAX_FRICTION_LINEAR_ACCELERATION);

    }

    if(pickedBody)
    {
        return class_body;
    }
    else
    {
        return NULL;
    }



}

To release pick:

Code: Select all

void realese_picking(newtworld* world)
{
    if(mousePickMode)
    {
        if (pickedBody)
        {
            CustomKinematicControllerSetPickMode (bodyPickController, 0); //I don't really understand what these three line does ...
            CustomKinematicControllerSetMaxAngularFriction (bodyPickController, 10.0f);
            CustomKinematicControllerSetMaxLinearFriction (bodyPickController, MAX_FRICTION_LINEAR_ACCELERATION);


            if (bodyPickController)
            {
                CustomDestroyJoint (bodyPickController);
            }
            bodyPickController = NULL;
        }

        mousePickMode = false;
    }

}

Here the crash code of windows :

Thank you to read me !

put a break point in the destrucotr and see if it call it. Or if it call a different operator delete.

[izissise]

So it stop at the break point at CustomDestroyJoint(bodyPickController); but the debugger received a Segmentation fault in JointLibrary!?SubmitConstraints@NewtonCustomJoint@@CAXPBUNewtonJoint@@MH@Z()

[izissise]

?? It's been three day !

[Julio Jerez]

I do not know what could that be, Ther is no reason fo eth engoien to crash in the constom joints.
can you link teh libary statically maybe you can see where crash happens?

[izissise]

If you want I can upload the project ...

[Julio Jerez]

ok,

[izissise]

http://www.megaupload.com/?d=ILFBL1M4

The file is too large to be upload on the forum so i upload it on megaupload !

The picking function are in fonction2.cpp
-Press s or e to switch between space and earth simulation
-Press space to add cube !

[izissise]

So do you find the problem ?

[Julio Jerez]

I can not download the file.
It ask for a password, and I type it, the it take me back to teh download again, and each time the wait time increase it.

[izissise]

For me it work great.......

so where i can upload it ?

[Stucuk]

Its a badly designed site. Basically you have to enter a capacha and then wait for about 50 seconds. Then it will say "Regular Download", which you then click. So you don't have to deal with Mega Upload's horrible website i have uploaded the guys file to http://www.stucuk.net/Newton project.rar for you so you can get a direct download.

[izissise]

Thank you stucuk , I know megaupload is evil but it is the only one has not to remove file after a while....

[Julio Jerez]

is Newton project.cbp a code block project? this is all source code
can you make and EXE that link to the netwon DLL, I do not use code project.

[izissise]

So I compiled a release version and the something strange happen with so i join you also the debug version to compare I don't join the texture so just add two png file named 1 and 2, I want also to say: all the cube have a mass but you'll see if you compare the two version.

So good luck to find the problem and thank you !!
