Bonjour tout de même ,
Aujourd'huin ayant fait l'arme de mon FPS futuriste, j'ai voulu faire un setParent a la camera, mais ca ne se voit pas.. Quand j'envoie un message sur la console, ca me met toujours les memes coordonées...
Voici mon bout de code

Voici un petit jeux : trouver l'erreur :

La doc :

setPosition (const core::vector3df &newpos)
Sets the position of the node relative to its parent.


ton code :

mesDh->setParent(camera);
...
mesDh->setPosition(irr::core::vector3df(camera->getPosition().X, -0.300993f, camera->getPosition().Z));

Je vois pas trop le problème...

EDIT : Ah, j'ai trouvé....

c'est toujour plus constructif de trouver par soi-meme les solutions aux problemes

Alors peut tu m'ésplique où est ton erreur car j'ai le même souci ! Merci d'avance !
