PackedVector4Array
A packed array ofVector4s.
Description
An array specifically designed to holdVector4. Packs data tightly, so it saves memory for large array sizes.
Differences between packed arrays, typed arrays, and untyped arrays: Packed arrays are generally faster to iterate on and modify compared to a typed array of the same type (e.g.PackedVector4Array versusArray[Vector4]
). Also, packed arrays consume less memory. As a downside, packed arrays are less flexible as they don't offer as many convenience methods such asArray.map(). Typed arrays are in turn faster to iterate on and modify than untyped arrays.
Note: Packed arrays are always passed by reference. To get a copy of an array that can be modified independently of the original array, useduplicate(). This isnot the case for built-in properties and methods. The returned packed array of these are a copies, and changing it willnot affect the original value. To update a built-in property you need to modify the returned array, and then assign it to the property again.
Note
There are notable differences when using this API with C#. SeeC# API differences to GDScript for more information.

Constructor Descriptions
PackedVector4ArrayPackedVector4Array()🔗
Constructs an emptyPackedVector4Array.
PackedVector4ArrayPackedVector4Array(from:PackedVector4Array)
Constructs aPackedVector4Array as a copy of the givenPackedVector4Array.
PackedVector4ArrayPackedVector4Array(from:Array)
Constructs a newPackedVector4Array. Optionally, you can pass in a genericArray that will be converted.
Note: When initializing aPackedVector4Array with elements, it must be initialized with anArray ofVector4 values:
vararray=PackedVector4Array([Vector4(12,34,56,78),Vector4(90,12,34,56)])
Method Descriptions
Appends an element at the end of the array (alias ofpush_back()).
voidappend_array(array:PackedVector4Array)🔗
Appends aPackedVector4Array at the end of this array.
intbsearch(value:Vector4, before:bool = 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, abefore
specifier can be passed. Iffalse
, the returned index comes after all existing entries of the value in the array.
Note: Callingbsearch() 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.
Clears the array. This is equivalent to usingresize() with a size of0
.
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.
PackedVector4Arrayduplicate()🔗
Creates a copy of the array, and returns it.
Assigns the given value to all elements in the array. This can typically be used together withresize() to create an array with a given size and initialized elements.
intfind(value:Vector4, from:int = 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.
Returns theVector4 at the givenindex
in the array. This is the same as using the[]
operator (array[index]
).
Returnstrue
if the array containsvalue
.
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.
intinsert(at_index:int, value:Vector4)🔗
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()
).
Returnstrue
if the array is empty.
Inserts aVector4 at the end.
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.
Reverses the order of the elements in the array.
intrfind(value:Vector4, from:int = -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.
voidset(index:int, value:Vector4)🔗
Changes theVector4 at the given index.
Returns the number of elements in the array.
PackedVector4Arrayslice(begin:int, end:int = 2147483647)const🔗
Returns the slice of thePackedVector4Array, frombegin
(inclusive) toend
(exclusive), as a newPackedVector4Array.
The absolute value ofbegin
andend
will be clamped to the array size, so the default value forend
makes it slice to the size of the array by default (i.e.arr.slice(1)
is a shorthand forarr.slice(1,arr.size())
).
If eitherbegin
orend
are negative, they will be relative to the end of the array (i.e.arr.slice(0,-2)
is a shorthand forarr.slice(0,arr.size()-2)
).
Sorts the elements of the array in ascending order.
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.
PackedByteArrayto_byte_array()const🔗
Returns aPackedByteArray with each vector encoded as bytes.
Operator Descriptions
booloperator !=(right:PackedVector4Array)🔗
Returnstrue
if contents of the arrays differ.
PackedVector4Arrayoperator +(right:PackedVector4Array)🔗
Returns a newPackedVector4Array with contents ofright
added at the end of this array. For better performance, consider usingappend_array() instead.
booloperator ==(right:PackedVector4Array)🔗
Returnstrue
if contents of both arrays are the same, i.e. they have all equalVector4s at the corresponding indices.
Vector4operator [](index:int)🔗
Returns theVector4 at indexindex
. Negative indices can be used to access the elements starting from the end. Using index out of array's bounds will result in an error.
