Detailed Description

MotionStateManager handles physics motion of objects.

Constructor & Destructor Documentation

◆ MotionStateManager()

MotionStateManager::MotionStateManager	(	btTransform &	pos,
		scene::ISceneNode *	node
	)

Set the private attributes.

Parameters

pos	btTransform (translation and rotation)
node	ISceneNode graphic object

                                                                              {
     this->initialPosition = pos;
     this->node = node;
 }

Member Function Documentation

◆ getWorldTransform()

void MotionStateManager::getWorldTransform ( btTransform & wordTrans ) const

virtual

Virtual method called by Bullet before setWorldTransform.

                                                                        {
     worldTrans = initialPosition;
 }

◆ setWorldTransform()

void MotionStateManager::setWorldTransform ( const btTransform & worldTrans )

virtual

Virtual method called by Bullet whenever there is a physics change to an object.

This is the right place to update graphic objects.

             if(this->node == nullptr) return;
             btQuaternion rotation = worldTrans.getRotation();
             btVector3 position = worldTrans.getOrigin();
             this->node->setPosition(toIrrlichtVector(position));
             this->node->updateAbsolutePosition();
             this->node->setRotation(QuaternionToEuler(rotation));
             this->initialPosition = worldTrans;
