Protected Attributes Documentation

variable bWasEvaluating

---

Private Attributes Documentation

variable TransitionClass

TSubclassOf< USMTransitionInstance > TransitionClass;

Select a custom node class to use for this node. This can be a blueprint or C++ class.

---

variable DelegateOwnerInstance

TEnumAsByte< ESMDelegateOwner > DelegateOwnerInstance;

The instance which owns the delegate the transition should bind to.

---

variable DelegateOwnerClass

TSubclassOf< UObject > DelegateOwnerClass;

The class of the instance containing the delegate.

---

variable DelegatePropertyGuid

FGuid DelegatePropertyGuid;

The guid assigned to this property if one exists.

---

variable DelegatePropertyName

FName DelegatePropertyName;

Available delegates.

---

variable bEventTriggersTargetedUpdate

uint8 bEventTriggersTargetedUpdate;

If the event should trigger a targeted update of the state machine limited to this transition and destination state.

This can efficiently allow state machines with tick disabled to update. This won't evaluate parallel or super state transitions.

This setting can also be changed on each Event Trigger Result Node.

---

variable bEventTriggersFullUpdate

uint8 bEventTriggersFullUpdate;

If the event should trigger a full update of the state machine. Setting this will be applied after 'Targeted Update'. A full update consists of evaluating transitions top down from the root state machine, as well as running OnStateUpdate if necessary.

This is a legacy setting. To maintain old legacy behavior enable this setting and disable 'Targeted Update'.

This setting can also be changed on each Event Trigger Result Node.

---

variable bCanEvaluate_DEPRECATED

uint8 bCanEvaluate_DEPRECATED;

Deprecated:

---

variable bCanEvaluateFromEvent_DEPRECATED

uint8 bCanEvaluateFromEvent_DEPRECATED;

Deprecated:

---

variable bCanEvalWithStartState_DEPRECATED

uint8 bCanEvalWithStartState_DEPRECATED;

Deprecated:

Set on the node template instead.

---

variable bAutoFormatGraph

uint8 bAutoFormatGraph;

Auto format the local graph and generate an expression for conditional evaluation. This will physically add or remove blueprint operator nodes to the local graph.

For more complex expressions generate the initial graph using the transition stack, uncheck Auto Format Graph, and update the blueprint operator nodes in the local graph.

This is ideal for quick prototyping or areas where performance isn't critical, but for optimal memory usage and performance use a single transition class instead. Even with pure C++ transition classes any operator nodes in the local graph will require blueprint graph evaluation.

---

variable bNOTPrimaryCondition

uint8 bNOTPrimaryCondition;

NOT the primary node instance or condition. No impact if only using pin defaults. Requires bAutoFormatGraph set.

---

variable TransitionStack

TArray< FTransitionStackContainer > TransitionStack;

Add additional transition classes so simple expressions can be used to determine if the transition should pass. Requires bAutoFormatGraph.

---

variable PriorityOrder_DEPRECATED

int32 PriorityOrder_DEPRECATED;

Deprecated:

---

variable AutoGeneratedStackNodes

---

variable InitialOperatorNode

TObjectPtr< UK2Node_CommutativeAssociativeBinaryOperator > InitialOperatorNode;
