UKismetArrayLibrary::SortStringArray
#include "Kismet/KismetArrayLibrary.h"
Access: public
Specifiers: staticBlueprintCallable
Description
Sorts an array of strings in place, alphabetically by default. Comparison uses standard lexicographic string ordering.
Caveats & Gotchas
- • Sorts the array in place and mutates TargetArray directly; there is no non-mutating overload that returns a sorted copy.
- • The default (unstable) sort does not preserve the relative order of duplicate strings — enable bStableSort if that matters, but expect a performance hit on large arrays.
- • Comparison is case-sensitive and ordinal, so uppercase letters sort before lowercase ones (e.g. "Zebra" sorts before "apple").
Signature
static void SortStringArray(UPARAM(Ref) TArray<FString>& TargetArray, bool bStableSort = false, EArraySortOrder SortOrder = EArraySortOrder::Ascending);Parameters
| Name | Type | Description | Default |
|---|---|---|---|
| TargetArray | TArray<FString>& | The array of strings to sort in place. | — |
| bStableSort | bool | If true, uses a stable sort that preserves the relative order of equal elements, at a performance cost. | false |
| SortOrder | EArraySortOrder | Whether to sort ascending or descending. | EArraySortOrder::Ascending |
Return Type
void Example
Sort tags alphabetically C++
TArray<FString> Tags = { "Zombie", "apple", "Banana" };
UKismetArrayLibrary::SortStringArray(Tags, false, EArraySortOrder::Ascending);
// Tags is now ["Banana", "Zombie", "apple"] due to case-sensitive ordinal comparisonTags
