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.

Nota

There are notable differences when using this API with C#. See Diferenças da API C# para GDScript for more information.

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.

Note: When initializing a PackedVector2Array with elements, it must be initialized with an Array of Vector2 values:

var array = PackedVector2Array([Vector2(12, 34), Vector2(56, 78)])

Method Descriptions

bool append ( Vector2 value )

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.


int bsearch ( Vector2 value, bool before=true )

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.

Note: Vectors with @GDScript.NAN elements don't behave the same as other vectors. Therefore, the results from this method may not be accurate if NaNs are included.


void clear ( )

Clears the array. This is equivalent to using resize with a size of 0.


int count ( Vector2 value ) const

Returns the number of times an element is in the array.

Note: Vectors with @GDScript.NAN elements don't behave the same as other vectors. Therefore, the results from this method may not be accurate if NaNs are included.


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.


int find ( Vector2 value, int from=0 ) const

Searches the array for a value and returns its index or -1 if not found. Optionally, the initial search index can be passed.

Note: Vectors with @GDScript.NAN elements don't behave the same as other vectors. Therefore, the results from this method may not be accurate if NaNs are included.


bool has ( Vector2 value ) const

Returns true if the array contains value.

Note: Vectors with @GDScript.NAN elements don't behave the same as other vectors. Therefore, the results from this method may not be accurate if NaNs are included.


int insert ( int at_index, Vector2 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.


bool push_back ( Vector2 value )

Inserts a Vector2 at the end.


void remove_at ( int index )

Removes an element from the array by index.


int resize ( int new_size )

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.


int rfind ( Vector2 value, int from=-1 ) const

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.

Note: Vectors with @GDScript.NAN elements don't behave the same as other vectors. Therefore, the results from this method may not be accurate if NaNs are included.


void set ( int index, Vector2 value )

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.sli
