Array Functions

Array_NextIndex

Returns the next index in the array. If the next index is greater than the last valid array index and bLoop is enabled, the index will loop back to the start of the array. Otherwise, the last index of the array will be returned.

Blueprint
C++

TArray<int32> TargetArray = {0, 1, 2, 3};
int32 Index = 2;
bool bLoop = true;
int32 NextIndex = UUDCoreFunctionLibrary::Array_NextIndex(TargetArray, Index, bLoop);

Inputs

TargetArray

TArray<int32>

required

The array to get the next index for.

Index

int32

required

The current index.

bLoop

bool

If true, the index will loop back to the beginning of the array when the next index is greater than the last array index. Otherwise, the last index will be returned.

Outputs

ReturnValue

int32

The next index in the array.

Array_PreviousIndex

Returns the previous index in the array. If the previous index is less than 0 and bLoop is enabled, the index will loop back to the end of the array. Otherwise, 0 will be returned.

Blueprint
C++

TArray<int32> TargetArray = {0, 1, 2, 3};
int32 Index = 1;
bool bLoop = true;
int32 PreviousIndex = UUDCoreFunctionLibrary::Array_PreviousIndex(TargetArray, Index, bLoop);

Inputs

TargetArray

TArray<int32>

required

The array to get the previous index for.

Index

int32

required

The current index.

bLoop

bool

If true, the index will loop back to the end of the array when the previous index is less than 0. Otherwise, 0 will be returned.

Outputs

ReturnValue

int32

The previous index in the array.
