Syntax

UCLASS&40;BlueprintType&41;  
class URigVMNode : public UObject

Remarks

The Node represents a single statement within a Graph. Nodes can represent values such as Variables / Parameters, they can represent Function Invocations or Control Flow logic statements (such as If conditions of For loops). Additionally Nodes are used to represent Comment statements. Nodes contain Pins to represent parameters for Function Invocations or Value access on Variables / Parameters.
