Syntax
class UK2Node_MathExpression : public [UK2Node_Composite](API\Editor\BlueprintGraph\UK2Node_Composite)
Remarks
This node type acts like a collapsed node, a single node that represents a larger sub-network of nodes (contained within a sub-graph). This node will take the math expression it was named with, and attempt to convert it into a series of math nodes. If it is unsuccessful, then it generates a series of actionable errors.
Variables
Type | Name | Description |
---|---|---|
bool | bMadeAfterRotChange | |
FString | Expression | The math expression to evaluate. |

Overridden from UK2Node_EditablePinBase
Type | Name | Description |
---|---|---|
bool | CanCreateUserDefinedPin ( const FEdGraphPinType& InPinType, EEdGraphPinDirection InDesiredDirec..., FText& OutErrorMessage ) | Queries if a user defined pin of the passed type can be constructed on this node. |
Overridden from UK2Node

---|---|---|
FNodeHandlin... | CreateNodeHandler ( FKismetCompilerContext& CompilerCo... ) | |
void | GetMenuActions ( FBlueprintActionDatabaseRegistrar&... ) | Replacement for GetMenuEntries(). |
bool | IsNodePure () | Returns whether this node is considered 'pure' by the compiler |
Overridden from UEdGraphNode
Type | Name | Description |
---|---|---|
void | FindDiffs ( UEdGraphNode* OtherNode, FDiffResults& Results ) | Gives the node the option to customize how diffs are discovered within it. |
FText | GetNodeTitle ( ENodeTitleType::Type TitleType ) | Gets the name of this node, shown in title bar |
TSharedPtr< ... | MakeNameValidator () | Create a name validator for this node |
void | OnRenameNode ( const FString& NewName ) | Called when this node is being renamed after a successful name validation |
void | PostPlacedNewNode () | A chance to initialize a new node; called just once when a new node is created, before AutowireNewNode or AllocateDefaultPins is called. |
void | ReconstructNode () | Refresh the connectors on a node, preserving as many connections as it can. |
bool | ShouldMergeChildGraphs () | If the node has a subgraph, should they be merged into the main graph? |
void | ValidateNodeDuringCompilation ( FCompilerResultsLog& MessageLog ) | Gives each visual node a chance to do final validation before it's node is harvested for use at runtime. |
Overridden from UObject
Type | Name | Description |
---|---|---|
void | PostEditChangeProperty ( FPropertyChangedEvent& PropertyCha... ) | Called when a property on this object has been modified externally |
void | Serialize ( FArchive& Ar ) | Handles reading, writing, and reference collecting using FArchive. |
