UKismetStringLibrary::JoinStringArray
#include "Kismet/KismetStringLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Concatenates all elements of SourceArray into a single string, inserting Separator between each element.
Caveats & Gotchas
- • An empty SourceArray returns an empty string rather than just the separator or an error.
- • The complement to ParseIntoArray; round-tripping through both is only lossless if none of the elements themselves contain the separator.
