bonjour,
Alors à partir de l'exemple 7 sur les collisions, j'ai fait quelque petite modification :
lorsque je clique sur un objet, je récupère le IsceneNode seulement j'aimerai pouvoir accéder au méthodes de l'IAnimatedMeshSceneNode.
J'ai essayé plusieurs choses, mais malheureusement ça plante.

voici la code :

#include <irrlicht.h>
#include <iostream>


using namespace irr;

class MyEventReceiver : public irr::IEventReceiver
{

    public:
    MyEventReceiver( scene::ISceneManager* smgr, gui::ICursorControl* curseur)
    {
        //node=0;

        selectedSceneNode = 0;
        lastSelectedSceneNode = 0;
        m_smgr = smgr;
        m_curseur = curseur;

    }

    bool OnEvent(const SEvent& event)
    {

        if (event.EventType == EET_MOUSE_INPUT_EVENT && event.MouseInput.Event == EMIE_LMOUSE_LEFT_UP)
        {
            core::line3d<f32> line;


            line.start = m_smgr->getActiveCamera()->getPosition();

            line.end = line.start + (m_smgr->getActiveCamera()->getTarget() - line.start).normalize() * 1000.0f;

            core::vector3df intersection;
            core::triangle3df tri;

            selectedSceneNode = m_smgr->getSceneCollisionManager()->getSceneNodeFromScreenCoordinatesBB(m_curseur->getPosition());


            if (lastSelectedSceneNode){
                lastSelectedSceneNode->setMaterialFlag(video::EMF_LIGHTING, true);
            }


            if (selectedSceneNode){
                selectedSceneNode->setMaterialFlag(video::EMF_LIGHTING, false);
                scene::IAnimatedMeshSceneNode* node=0;

                selectedSceneNode->addChild(node);   //essai1 avec addchild
                //node->setParent(selectedSceneNode);  //essai2 avec set parent
                std::cout<<"modifie animaion speed :"<<std::endl;
                node->setAnimationSpeed(5); //fait planter l'application
                std::cout<<"fin modifie :"<<std::endl;

                lastSelectedSceneNode = selectedSceneNode;

                /**
                Ici je voudrai acceder au methodes de l'AnimatedMeshSceneNode !!
                Par exemple : utiliser setAnimationSpeed(5);
                    ou  récupéré le nom du personnage pour une classe qui herite de AnimatedMeshSceneNode
                **/

            }
        }
    }

    protected:
        //scene::IAnimatedMeshSceneNode* node;
        scene::ISceneNode* selectedSceneNode;
        scene::ISceneNode* lastSelectedSceneNode;
