PackedVector2Array¶
A packed array of Vector2s.
Description¶
An array specifically designed to hold Vector2. Packs data tightly, so it saves memory for large array sizes.

Constructor Descriptions¶
PackedVector2Array PackedVector2Array ( )
Constructs an empty PackedVector2Array
.
PackedVector2Array PackedVector2Array ( PackedVector2Array from )
Constructs a PackedVector2Array
as a copy of the given PackedVector2Array
.
PackedVector2Array PackedVector2Array ( Array from )
Constructs a new PackedVector2Array
. 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 ( PackedVector2Array array )
Appends a PackedVector2Array
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.
Returns the number of times an element is in the array.
PackedVector2Array duplicate ( )
Creates a copy of the array, and returns it.
void fill ( Vector2 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.
Searches the array for a value and returns its index or -1
if not found. Optionally, the initial search index can be passed.
Returns true
if the array contains value
.
Inserts a new element 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.
Inserts a Vector2 at the end.
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.
Searches the array in reverse order. Optionally, a start search index can be passed. If negative, the start index is considered relative to the end of the array.
Changes the Vector2 at the given index.
int size ( ) const
Returns the number of elements in the array.
PackedVector2Array slice ( int begin, int end=2147483647 ) const
Returns the slice of the PackedVector2Array
, from begin
(inclusive) to end
(exclusive), as a new PackedVector2Array
.
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.
