UKismetMathLibrary::InRange_Int64Int64

function Engine Blueprint Since unknown

#include "Kismet/KismetMathLibrary.h"

Access: public Specifiers: staticUFUNCTIONBlueprintPure

Description

Returns true if Value falls within [Min, Max]. Both bounds are inclusive by default; pass false to make either bound exclusive.

Caveats & Gotchas

• The function does not validate that Min <= Max. Passing an inverted range (Min > Max) always returns false, which can silently swallow valid values — assert or clamp the bounds before calling.
• The Blueprint node metadata pins Min and Max default to literals 0 and 10. When wiring from a variable, always explicitly override these literal defaults on the node or they will silently clamp your range to [0, 10].

Signature

static ENGINE_API bool InRange_Int64Int64(int64 Value, int64 Min, int64 Max, bool InclusiveMin = true, bool InclusiveMax = true);

Parameters

Name	Type	Description	Default
Value	int64	The value to test.	—
Min	int64	Lower bound of the range.	—
Max	int64	Upper bound of the range.	—
InclusiveMin	bool	If true, Value == Min counts as in-range.	true
InclusiveMax	bool	If true, Value == Max counts as in-range.	true

Return Type

bool

Example

Validate a row ID is within a valid shard range C++

int64 RowID = GetRowID();
int64 ShardMin = 1000000000LL;
int64 ShardMax = 1999999999LL;
if (UKismetMathLibrary::InRange_Int64Int64(RowID, ShardMin, ShardMax))
{
    DispatchToShard(RowID);
}
