PackedInt64Array¶
A packed Array of 64-bit integers.
Description¶
An Array specifically designed to hold 64-bit integer values. Packs data tightly, so it saves memory for large array sizes.
Note: This type stores signed 64-bit integers, which means it can take values in the interval [-2^63, 2^63 - 1]
, i.e. [-9223372036854775808, 9223372036854775807]
. Exceeding those bounds will wrap around. If you only need to pack 32-bit integers tightly, see PackedInt32Array for a more memory-friendly alternative.

Constructor Descriptions¶
PackedInt64Array PackedInt64Array ( )
Constructs an empty PackedInt64Array
.
PackedInt64Array PackedInt64Array ( PackedInt64Array from )
Constructs a PackedInt64Array
as a copy of the given PackedInt64Array
.
PackedInt64Array PackedInt64Array ( Array from )
Constructs a new PackedInt64Array
. Optionally, you can pass in a generic Array that will be converted.
Method Descriptions¶
Appends an element at the end of the array (alias of push_back).
void append_array ( PackedInt64Array array )
Appends a PackedInt64Array
at the end of this array.
Finds the index of an existing value (or the insertion index that maintains sorting order, if the value is not yet present in the array) using binary search. Optionally, a before
specifier can be passed. If false
, the returned index comes after all existing entries of the value in the array.
Note: Calling bsearch on an unsorted array results in unexpected behavior.
PackedInt64Array duplicate ( )
Creates a copy of the array, and returns it.
void fill ( int value )
Assigns the given value to all elements in the array. This can typically be used together with resize to create an array with a given size and initialized elements.
Returns true
if the array contains value
.
Inserts a new integer at a given position in the array. The position must be valid, or at the end of the array (idx == size()
).
bool is_empty ( ) const
Returns true
if the array is empty.
Appends a value to the array.
void remove_at ( int index )
Removes an element from the array by index.
Sets the size of the array. If the array is grown, reserves elements at the end of the array. If the array is shrunk, truncates the array to the new size.
void reverse ( )
Reverses the order of the elements in the array.
Changes the integer at the given index.
int size ( ) const
Returns the number of elements in the array.
PackedInt64Array slice ( int begin, int end=2147483647 ) const
Returns the slice of the PackedInt64Array
, from begin
(inclusive) to end
(exclusive), as a new PackedInt64Array
.
The absolute value of begin
and end
will be clamped to the array size, so the default value for end
makes it slice to the size of the array by default (i.e. arr.slice(1)
is a shorthand for arr.slice(1, arr.size())
).
If either begin
or end
are negative, they will be relative to the end of the array (i.e. arr.slice(0, -2)
is a shorthand for arr.slice(0, arr.size() - 2)
).
void sort ( )
Sorts the elements of the array in ascending order.
PackedByteArray to_byte_array ( ) const
Returns a copy of the data converted to a PackedByteArray, where each element have been encoded as 8 bytes.
The size of the new array will be int64_array.size() * 8
.
