Public Member Functions
	RootNode (entt::registry &registry)
Public Member Functions inherited from EngineCore::SceneNode
	~SceneNode ()
Ecs::LocalTransform &	getLocalTransform ()
	Gets the local transform of the scene node. The local transform is relative to the parent node.
const Ecs::LocalTransform &	getLocalTransform () const
void	registerWithEcs ()
entt::entity	getEntity () const
	Gets the entity associated with this scene node.
void	setWorldPosition (const glm::vec3 &newLocation)
	Sets the world position of the scene node. This will calculate the corresponding local position based on the parent's world transform.
void	setWorldRotation (const glm::vec3 &newRotation)
	Sets the world rotation of this node with euler angles.
void	setWorldRotation (const glm::quat &newRotation)
	Sets a new world rotation with a quaternion on this node.
void	rotateWorld (const glm::vec3 &deltaRotation)
	Applies an incremental rotation to the current world rotation using quaternion multiplication. This avoids euler angle instability that occurs with get/set rotation round-trips.
void	rotateWorld (const glm::quat &deltaRotation)
	Applies an incremental rotation to the current world rotation using quaternion multiplication.
void	setWorldScale (const glm::vec3 &newScale)
	sets the scale for this node
void	setLocalModelMatrix (const glm::mat4 &newModelMatrix)
	Overwrites all components of the transform.
void	setWorldModelMatrix (const glm::mat4 &newModelMatrix)
	Overwrites all components of this transform.
void	addChild (const std::shared_ptr< SceneNode > &newChild)
	Adds a child node to this node.
void	addChildren (std::vector< std::shared_ptr< SceneNode > > newChildren)
	adds new children to this node
void	clearChildren ()
	Removes all children from this node.
void	removeChild (const std::shared_ptr< SceneNode > &child)
	Removes a single child from this node.
const glm::mat4 &	getWorldMatrix () const
	get the world matrix as a raw glm matrix
bool	isWorldMatrixDirty () const
	Checks if the world matrix has to be recalculated.
bool	isRoot () const
	Checks if this node is the root node.
std::vector< std::weak_ptr< SceneNode > >	getChildren () const
	Get a list of all children of this node.
void	markDirtyRecursive ()
	Marks this node and its children as dirty.
