UKismetArrayLibrary::SortIntArray

function Engine Blueprint Since unknown

#include "Kismet/KismetArrayLibrary.h"

Access: public Specifiers: staticBlueprintCallable

Description

Sorts an array of 32-bit integers in place by numeric value. Shows in the Blueprint palette as "Sort Integer Array".

Caveats & Gotchas

• Sorts in place and mutates TargetArray directly; there is no non-mutating overload that returns a sorted copy.
• Only supports int32 — for 64-bit integers use SortInt64Array instead, since implicit truncation is not performed.

Signature

static void SortIntArray(UPARAM(Ref) TArray<int32>& TargetArray, bool bStableSort = false, EArraySortOrder SortOrder = EArraySortOrder::Ascending);

Parameters

Name	Type	Description	Default
TargetArray	TArray<int32>&	The array of integers 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 scores descending C++

TArray<int32> Scores = { 42, 7, 99, 15 };
UKismetArrayLibrary::SortIntArray(Scores, false, EArraySortOrder::Descending);
// Scores is now [99, 42, 15, 7]
