Specifiers: staticBlueprintPureUFUNCTION
Description
Returns A if bPickA is true, otherwise returns B. A Blueprint-friendly conditional select that avoids a branch node when the choice between two constant strings is driven by a single boolean.
Caveats & Gotchas
- • Both A and B are fully evaluated before the selection is made — there is no short-circuit behaviour. If either string is produced by an expensive or side-effectful expression upstream in a Blueprint graph, both costs are always paid regardless of bPickA.
- • For choosing between more than two options, use a Map lookup or a Switch on String node instead of nested SelectString calls, which become unreadable and error-prone.
