Functions

  Type Name Description
Public function Static void  
Public function Virtual void  
Public function Virtual void

DryRun ( const TArray< UAvaPlaybackNode* >& InAncestors
)

 Called while Dry Running the Graph. This can be called multiple times for nodes that are connected to multiple nodes.
Public function void

DryRunNode ( TArray< UAvaPlaybackNode* >& InAncestors
)

 Handles the 'Dry' run of the Node. This is called when Compiling the Graph.
Public function Virtual Const bool  
Public function void

GetAllNodes ( TArray< UAvaPlaybackNode* >& OutPlaybackNodes
)

 Recursive call to get all the Nodes connected to this Node (inclusive)
Public function Const double

GetChildLastTimeTicked ( int32 ChildIndex
)

  
Public function Const const TArray< TObjectPtr< UAvaPlaybackNode > > &  
Public function Const UEdGraphNode *  
Public function Virtual Const FName

GetInputPinName ( int32 InputPinIndex
)

  
Public function Const double  
Public function Virtual Const int32  
Public function Virtual Const int32  
Public function Virtual Const FText Gets the Display Category of the Node
Public function Virtual Const FText Gets the Display Name of the Node
Public function Virtual Const FText Gets the ToolTip of the Node
Public function Const UAvaPlaybackGraph *  
Public function Virtual void  
Public function void Called when the Child at ChildIndex, made a connection to a Player Node successfully This updates the Last Ticked Times and stores them both in This Node and the Child Node that caused the connection
Public function Virtual void

NotifyPlaybackStateChanged ( bool bPlaying
)

 Called when the UAvaPlaybackGraph changes its state from Playing <-> Stopped
Public function Virtual void Called either when the Node has been Constructed (new node) or from Post Load
Public function Virtual void Called after Dry Running the Graph. This is called once per node.
Public function Virtual void Called before Dry Running the Graph. This is called once per node.
Public function Virtual void  
Public function Virtual void

RefreshNode ( bool bDryRunGraph
)

  
Public function Virtual void  
Public function void

SetChildNodes ( TArray< UAvaPlaybackNode* >&& InChildNodes
)

  
Public function void

SetGraphNode ( UEdGraphNode* InGraphNode
)

  
Public function Virtual void

Tick ( float DeltaTime,
FAvaPlaybackChannelParameters& ChannelParameters
)

 Handles the 'Raw' ticking of the Node.
Public function void

TickChild ( float DeltaTime,
int32 ChildIndex,
FAvaPlaybackChannelParameters& ChannelParameters
)

 Ticks Childs as well as checking if the Child actually made connection to a Player Node If the Ticking results in valid Channel Parameters, then it calls 'NotifyChildNodeSucceeded'

Overridden from UObject

  Type Name Description
Public function Virtual void Called before destroying the object.
Public function Virtual void

PostEditChangeProperty ( FPropertyChangedEvent& PropertyChangedEvent
)

 Called when a property on this object has been modified externally
Public function Virtual void Do any object-specific cleanup required immediately after loading an object.
Public function Virtual void Handles reading, writing, and reference collecting using FArchive.

Overridden from UObjectBaseUtility

  Type Name Description
Public function Virtual Const bool Called after load to determine if the object can be a cluster root
Public function Virtual Const bool Called during cluster construction if the object can be added to a cluster
