Member Function Documentation

◆ AddRootNode()

void EMotionFX::Skeleton::AddRootNode ( size_t nodeIndex )

Add a root node to the actor. This doesn't modify the node itself, but it will add the node to the list of root nodes.

Parameters

nodeIndex The node number/index to add and mark as root node inside the actor.

◆ FindNodeAndIndexByName()

Node * EMotionFX::Skeleton::FindNodeAndIndexByName	(	const AZStd::string &	name,
		size_t &	outIndex
	)		const

Find a joint's index and pointer by name.

Parameters

name	The name of the joint, non case sensitive.
outIndex	This will contain the resulting index, or MCORE_INVALIDINDEX32 in case not found.

Returns: This returns a pointer to the joint or nullptr when not found. In case of a nullptr, the outIndex will be set to MCORE_INVALIDINDEX32 as well.

◆ FindNodeByID()

Node * EMotionFX::Skeleton::FindNodeByID ( size_t id ) const

Search for a node on ID. Returns nullptr when no node found. A node ID is based on the name. So all nodes (also inside other actors) with the same name will have the same ID. This can be used for faster searching, compared to searching by name, which uses string compares.

Parameters

id	The ID to search for.

Returns: A pointer to the node, or nullptr when no node with the given ID found.

◆ FindNodeByName()

Node * EMotionFX::Skeleton::FindNodeByName ( const char * name ) const

Search for a node by name (case sensitive).

Parameters

name	The name of the node (case sensitive).

Returns: A pointer to the node, returns nullptr when not found.

◆ FindNodeByNameNoCase()

Node * EMotionFX::Skeleton::FindNodeByNameNoCase ( const char * name ) const

Search for a node by name (non case sensitive), returns nullptr when no node can be found. Note: when there are two nodes with the same non case sensitive name, the first one is returned. So if there is a node named "Blah" and one named "BLAH" and we search on "blah", the first one ("Blah") is returned.

Parameters

name	The name of the node, non case sensitive.

Returns: A pointer to the node with the given name, or nullptr when none could be found.

◆ GetNumRootNodes()

MCORE_INLINE size_t EMotionFX::Skeleton::GetNumRootNodes ( ) const

inline

Get the number of root nodes in the actor. A root node is a node without any parent.

Returns: The number of root nodes inside the actor.

◆ GetRootNodeIndex()

MCORE_INLINE size_t EMotionFX::Skeleton::GetRootNodeIndex ( size_t nr ) const

inline

Get the node number/index of a given root node.

Parameters

nr	The root node number, which must be in range of [0..GetNumRootNodes()-1].

Returns: The node index of the given root node.

◆ RemoveAllRootNodes()

void EMotionFX::Skeleton::RemoveAllRootNodes ( )

Removes all root nodes from the actor. This doesn't remove the actual nodes, but it just unregisters them as root nodes, so that the GetNumRootNodes() method will return a value of zero.

◆ RemoveRootNode()

void EMotionFX::Skeleton::RemoveRootNode ( size_t nr )

Remove a given root node from the list of root nodes stored inside the actor. This doesn't really remove the node itself, but it just unregisters it as root node inside the actor.

Parameters

nr	The root node to remove, which must be in range of [0..GetNumRootNodes()-1].

◆ ReserveRootNodes()

void EMotionFX::Skeleton::ReserveRootNodes ( size_t numNodes )

Pre-allocate space for the root nodes array. This does not alter the value returned by GetNumRootNodes() though.

Parameters

numNodes The absolute number of nodes to pre-allocate space for.

◆ SetNode()

void EMotionFX::Skeleton::SetNode	(	size_t	index,
		Node *	node
	)

Set the value of a given node.

Parameters

index	The node number, which must be in range of [0..GetNumNodes()-1].
node	The node value to set at this index.

◆ SetNumNodes()

void EMotionFX::Skeleton::SetNumNodes ( size_t numNodes )

Set the number of nodes. This resizes the array of pointers to nodes, but doesn't actually create the nodes.

Parameters

numNodes The number of nodes to allocate space for.

◆ UpdateNodeIndexValues()

void EMotionFX::Skeleton::UpdateNodeIndexValues ( size_t startNode = 0 )

Update all the node index values that are returned by the Node::GetNodeIndex() method. When the order or layout of the nodes array changes, for example after removing a node, the index values of the nodes have to be updated. As node number 5 could become node number 4 in the example case.

Parameters

startNode The node number to start updating from.
