Variables
| Type | Name | Description | |
|---|---|---|---|
    |
TEnumAsByte< EIfThenElseType > | ComparisonType | The type of comparison to use. Individual = IndividualComponent of the components are individually passed through the comparison. AllComponents = All components must succeed check to trigger the Then part of the statement. Magnitude = Grayscale value of the color is used in comparison. |
   |
FTG_Variant | Else | The value to return if the comparison is unsuccessful if ( |
   |
FTG_Variant | LHS | The LHS value for the comparison (LHS |
    |
TEnumAsByte< EIfThenElseOperator > | Operator | The type of operator in LHS |
   |
FTG_Variant | RHS | The RHS value for the comparison (LHS |
   |
FTG_Variant | Then | The value to return if the comparison is successful if ( |

FTG_EvaluationContext* InContext, |
Most of the time these are the two functions that expressions will need to implement. |

  |
FVector4f | EvaluateVector_WithValue
(
FTG_EvaluationContext* InContext, |
Evaluate vector only needs to be implemented if there vector handling isn't just a component-wise scalar handling. |
  |
std::vector< FTG_Variant > | If you use the basic structure of variant expression then you'll need to implement this correctly. |
