UKismetArrayLibrary::SortFloatArray

function Engine Blueprint Since unknown

#include "Kismet/KismetArrayLibrary.h"

Access: public Specifiers: staticBlueprintCallable

Description

Sorts an array of floating-point values in place by numeric value. The parameter type is TArray<double> since Blueprint's "float" maps to double-precision internally.

Caveats & Gotchas

• Sorts in place and mutates TargetArray directly; there is no non-mutating overload.
• The underlying element type is double even though the Blueprint node reads as "float" — matters if you're calling this from C++ against a TArray<float>, which will not bind without conversion.

Signature

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

Parameters

Name	Type	Description	Default
TargetArray	TArray<double>&	The array of floating-point values 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 distances ascending C++

TArray<double> Distances = { 350.5, 12.75, 980.0, 4.2 };
UKismetArrayLibrary::SortFloatArray(Distances, false, EArraySortOrder::Ascending);
// Distances is now [4.2, 12.75, 350.5, 980.0]
