enum EArrayChangeType

Enumerator	Value	Description
SetElement		Set the value of the provided index, resizing the array to match if necessary.
RemoveElement		Remove the element from the array at the provided index.
Clear		Clear all elements from the array.
AddElement		Append a default-constructed element to the end of the array.
InsertElement		Insert a default-constructed element at PropertyIndex, shifting subsequent elements up.
DuplicateElement		Duplicate the element at PropertyIndex; pin literals and wired property graphs are preserved.
MoveElement		Reorder the element at PropertyIndex to TargetIndex, preserving element guids and wired graphs.

Handle array processing.

function CreateStateNode

virtual USMGraphNode_StateNodeBase * CreateStateNode(
    USMBlueprint * InBlueprint,
    const FCreateStateNodeArgs & InStateArgs
) =0

Create a new state graph node in a blueprint.

Parameters:

InBlueprint

The blueprint to place the node.

InStateArgs

Arguments to use when creating the state.

Return: The newly created state node if successful.

---

function CreateStateNode

template <typename T >
inline T * CreateStateNode(
    USMBlueprint * InBlueprint,
    const FCreateStateNodeArgs & InStateArgs
)

---

function CreateTransitionEdge

virtual USMGraphNode_TransitionEdge * CreateTransitionEdge(
    USMBlueprint * InBlueprint,
    const FCreateTransitionEdgeArgs & InTransitionArgs
) =0

Create a new transition between two states.

Parameters:

InBlueprint

The blueprint to place the edge.

InTransitionArgs

Arguments to use to create the transition.

Return: The newly created transition edge if successful.

---

function CreateTransitionEdge

template <typename T >
inline T * CreateTransitionEdge(
    USMBlueprint * InBlueprint,
    const FCreateTransitionEdgeArgs & InTransitionArgs
)

---

function CreateStateStackInstance

virtual USMStateInstance * CreateStateStackInstance(
    USMGraphNode_StateNode * InStateNode,
    const FCreateStateStackArgs & InStateStackArgs
) =0

Create and add a state instance to a state stack.

Parameters:

InStateNode

The state node which should contain the state stack.

InStateStackArgs

The arguments to use when adding the state instance to the stack.

Return: The created state stack instance.

---

function CreateTransitionStackInstance

virtual USMTransitionInstance * CreateTransitionStackInstance(
    USMGraphNode_TransitionEdge * InTransitionEdge,
    const FCreateTransitionStackArgs & InTransitionStackArgs
) =0

Create and add a transition instance to a transition stack.

Parameters:

InTransitionEdge

The transition edge which should contain the transition stack.

InTransitionStackArgs

The arguments to use when adding the transition instance to the stack.

Return: The created transition stack instance.

---

function SetNodePropertyValue

virtual bool SetNodePropertyValue(
    USMGraphNode_Base * InGraphNode,
    const FSetNodePropertyArgs & InPropertyArgs
) =0

Set the value of a property on a graph node. This can be a state or transition. The property can be public, non-public, or a custom graph property (Such as a TextGraph).

Parameters:

InGraphNode

The graph node containing the property to modify.

InPropertyArgs

The property arguments.

Return: True if the value was set successfully.

---

function RemoveNode

virtual bool RemoveNode(
    USMGraphNode_Base * InGraphNode
) =0

Remove a graph node from its owning blueprint, breaking all connected pins.

Parameters:

InGraphNode

The graph node to remove.

Return: True if the node was removed successfully.

---

function SetInitialState

virtual bool SetInitialState(
    USMGraphNode_StateNodeBase * InStateNode
) =0

Rewire the entry node of a state graph to target a different state. Breaks any existing entry connection before creating the new one.

Parameters:

InStateNode

The state node to wire as the initial state. Must live in a USMGraph.

Return: True if the entry wiring was updated successfully.
