UKismetMathLibrary::SelectClass

Access: public
Specifiers: staticUFUNCTIONBlueprintPure
Description
Returns A if bSelectA is true, otherwise returns B. Picks between two class references, useful for dynamic spawning logic that varies the actor class based on a condition.
Caveats & Gotchas
- • No type-safety checking is performed — ensure both classes are compatible with whatever system consumes the result (e.g., the SpawnActor node's class pin expects a common base class).
- • Either input may be null; passing null to SpawnActor will assert or silently fail, so validate the result with IsValid before spawning.
