Axis of rotation

[Soldier of infortune]

Hello !

I have a character (ms3d) with the head, the left arm and the right arm attach to a node named "bip01", I can rotate the head separatly. But i have a problem with the rotation of arms : Error of axis of rotation. So I'd like to know how to change the axis of rotation of an node (an ms3d mesh) ?

Thanks in advance.

How are your rotating it currently show us some code?

Code to rotate the arms with the keyboard:

Code: Select all

case KEY_KEY_Y:
	{
	core::vector3df r = perso2_bras_gauche->getRotation();
	if (r.X == 360)
		r.X=0.0f;
	else
		r.X += 1.0f;
	perso2_bras_gauche->setRotation(r);
	}
	return true;


case KEY_KEY_H:
	{
	core::vector3df r = perso2_bras_gauche->getRotation();
	if (r.X == 360)
		r.X=0.0f;
	else
		r.X -= 1.0f;
	perso2_bras_gauche->setRotation(r);
	}
	return true;

Code to display the body (perso = character; corps = body) :

Code: Select all

	scene::IAnimatedMesh* mesh = 0;
	mesh = smgr->getMesh("./perso2/corps.ms3d");
	if (mesh)
		{

		perso2_corps = smgr->addAnimatedMeshSceneNode(mesh);
		scene::ISceneNodeAnimator* perso2_corps_col = smgr->createCollisionResponseAnimator(
			selector, perso2_corps, core::vector3df(10,40,10),
			core::vector3df(0,-100,0), 100.0f,
			core::vector3df(0,-40,0));

		perso2_corps->addAnimator(perso2_corps_col);
		perso2_corps_col->drop();

		if (perso2_corps)
			{
			perso2_corps->setPosition(core::vector3df(0,0,0));
			perso2_corps->setMaterialTexture(0, device->getVideoDriver()->getTexture("./perso2/corps.bmp"));
			perso2_corps->setMaterialFlag(video::EMF_LIGHTING, true);
			perso2_corps->addShadowVolumeSceneNode();
			}
		}

Code to display the body (bras = arm; gauche = left) :

Code: Select all

	scene::IAnimatedMesh* mesh2 = 0;
	mesh2 = smgr->getMesh("./perso2/bras_gauche.ms3d");
	if (mesh2)
		{
		perso2_bras_gauche = smgr->addAnimatedMeshSceneNode(mesh2);
		if (perso2_bras_gauche)
			{
			perso2_bras_gauche->setAnimationSpeed(25);
			perso2_bras_gauche->setMaterialTexture(0, device->getVideoDriver()->getTexture("./perso2/corps.bmp"));
			perso2_bras_gauche->setMaterialFlag(video::EMF_LIGHTING, true);
			perso2_bras_gauche->addShadowVolumeSceneNode();
			}
	}


	scene::ISceneNode *bras_gauche = perso2_corps->getMS3DJointNode("Bip01");
	perso2_bras_gauche->setPosition(core::vector3df(0,0,0));
	tete->addChild (perso2_bras_gauche);

The first picture shows the arm attached to the body :
