PackedVector2Array
A packed array of Vector2s.
class PackedVector2ArrayAn array specifically designed to hold Vector2. Packs data tightly, so it saves memory for large array sizes.

Conformances
protocol BidirectionalCollection<Element>A collection that supports backward as well as forward traversal.
protocol Collection<Element>A sequence whose elements can be traversed multiple times, nondestructively, and accessed by an indexed subscript.
protocol ContentVariantRepresentableSome of Godot’s builtin classes use ContentType for storage. This needs to be public because it affects their initialization, but SwiftGodot users should never need to conform their types to
ContentVariantRepresentable.protocol EquatableA type that can be compared for value equality.
protocol RandomAccessCollection<Element>A collection that supports efficient random-access index traversal.
protocol Sequence<Element>A type that provides sequential, iterated access to its elements.
protocol VariantRepresentableTypes that conform to VariantRepresentable can be stored directly in
Variantwith no conversion. These include all of the Variant types from Godot (for exampleGString,Rect,Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.protocol VariantStorableTypes that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

trueif contents of the arrays differ.static func * (lhs: PackedVector2Array, rhs: Transform2D) -> PackedVector2Array Returns a new
PackedVector2Arraywith all vectors in this array inversely transformed (multiplied) by the givenTransform2Dtransformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).static func + (lhs: PackedVector2Array, rhs: PackedVector2Array) -> PackedVector2Array Returns a new
PackedVector2Arraywith contents ofrightadded at the end of this array. For better performance, consider usingappendArray(array:)instead.static func == (lhs: PackedVector2Array, rhs: PackedVector2Array) -> Bool Returns

var content: ContentTypevar count: IntThe number of elements in the array
var endIndex: Intvar startIndex: Intsubscript(Int) -> Vector2 Accesses a specific element in the
PackedVector2Arrayfunc append(Vector2) -> Bool Appends an element at the end of the array (alias of
pushBack(value:)).func appendArray(PackedVector2Array) Appends a
PackedVector2Arrayat the end of this array.func bsearch(value: Vector2, before: Bool) -> Int64 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
beforespecifier can be passed. Iffalse, the returned index comes after all existing entries of the value in the array.func clear() Clears the array. This is equivalent to using
resize(newSize:)with a size of0.func count(value: Vector2) -> Int64 Returns the number of times an element is in the array.
func duplicate() -> PackedVector2Array Creates a copy of the array, and returns it.
func fill(value: Vector2) Assigns the given value to all elements in the array. This can typically be used together with
resize(newSize:)to create an array with a given size and initialized elements.func find(value: Vector2, from: Int64) -> Int64 Searches the array for a value and returns its index or
-1if not found. Optionally, the initial search index can be passed.func has(value: Vector2) -> Bool Returns
trueif the array containsvalue.func index(after: Int) -> Int func index(before: Int) -> Int func insert(atIndex: Int64, value: Vector2) -> Int64 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()).func isEmpty() -> Bool Returns
trueif the array is empty.func pushBack(value: Vector2) -> Bool Inserts a
Vector2at the end.func removeAt(index: Int64) Removes an element from the array by index.
func resize(newSize: Int64) -> Int64 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.
func reverse() Reverses the order of the elements in the array.
func rfind(value: Vector2, from: Int64) -> Int64 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.
func set(index: Int64, value: Vector2) Changes the
Vector2at the given index.func size() -> Int64 Returns the number of elements in the array.
func slice(begin: Int64, end: Int64) -> PackedVector2Array Returns the slice of the
PackedVector2Array, frombegin(inclusive) toend(exclusive), as a newPackedVector2Array.func sort() Sorts the elements of the array in ascending order.
func toByteArray() -> PackedByteArray Returns a
PackedByteArraywith each vector encoded as bytes.
