An array specifically designed to hold [Vector4]. Packs data tightly, so it saves memory for large array sizes.
[b]Note:[/b] Packed arrays are always passed by reference. To get a copy of an array that can be modified independently of the original array, use [method duplicate]. This is [i]not[/i] the case for built-in properties and methods. The returned packed array of these are a copies, and changing it will [i]not[/i] 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.
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 [param before] specifier can be passed. If [code]false[/code], the returned index comes after all existing entries of the value in the array.
[b]Note:[/b] Calling [method bsearch] on an unsorted array results in unexpected behavior.
[b]Note:[/b] Vectors with [constant @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.

<methodname="clear">
<returntype="void"/>
<description>
Clears the array. This is equivalent to using [method resize] with a size of [code]0[/code].
</description>
</method>
<methodname="count"qualifiers="const">
<returntype="int"/>
<paramindex="0"name="value"type="Vector4"/>
<description>
Returns the number of times an element is in the array.

</description>
</method>
<methodname="duplicate">
<returntype="PackedVector4Array"/>
<description>
Creates a copy of the array, and returns it.
</description>
</method>
<methodname="fill">
<returntype="void"/>
<paramindex="0"name="value"type="Vector4"/>
<description>
Assigns the given value to all elements in the array. This can typically be used together with [method resize] to create an array with a given size and initialized elements.
</description>
</method>
<methodname="find"qualifiers="const">
<returntype="int"/>
<paramindex="0"name="value"type="Vector4"/>
<paramindex="1"name="from"type="int"default="0"/>
<description>
Searches the array for a value and returns its index or [code]-1[/code] if not found. Optionally, the initial search index can be passed.
[b]Note:[/b] Vectors with [constant @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 [code]true[/code] if the array contains [param value].

</method>
<methodname="insert">
<returntype="int"/>
<paramindex="0"name="at_index"type="int"/>
<paramindex="1"name="value"type="Vector4"/>
<description>
Inserts a new element at a given position in the array. The position must be valid, or at the end of the array ([code]idx == size()[/code]).
</description>
</method>
<methodname="is_empty"qualifiers="const">
<returntype="bool"/>
<description>
Returns [code]true[/code] if the array is empty.
</description>
</method>
<methodname="push_back">
<returntype="bool"/>
<paramindex="0"name="value"type="Vector4"/>
<description>
Inserts a [Vector4] at the end.
</description>
</method>
<methodname="remove_at">
<returntype="void"/>
<paramindex="0"name="index"type="int"/>
<description>
Removes an element from the array by index.
</description>
</method>
<methodname="resize">
<returntype="int"/>
<paramindex="0"name="new_size"type="int"/>
<description>
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.
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.
[b]Note:[/b] Vectors with [constant @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 the slice of the [PackedVector4Array], from [param begin] (inclusive) to [param end] (exclusive), as a new [PackedVector4Array].
The absolute value of [param begin] and [param end] will be clamped to the array size, so the default value for [param end] makes it slice to the size of the array by default (i.e. [code]arr.slice(1)[/code] is a shorthand for [code]arr.slice(1, arr.size())[/code]).
If either [param begin] or [param end] are negative, they will be relative to the end of the array (i.e. [code]arr.slice(0, -2)[/code] is a shorthand for [code]arr.slice(0, arr.size() - 2)[/code]).
</description>
</method>
<methodname="sort">
<returntype="void"/>
<description>
Sorts the elements of the array in ascending order.
[b]Note:[/b] Vectors with [constant @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.
</description>
</method>
<methodname="to_byte_array"qualifiers="const">
<returntype="PackedByteArray"/>
<description>
Returns a [PackedByteArray] with each vector encoded as bytes.
Returns a new [PackedVector4Array] with contents of [param right] added at the end of this array. For better performance, consider using [method append_array] instead.
Returns [code]true[/code] if contents of both arrays are the same, i.e. they have all equal [Vector4]s at the corresponding indices.
</description>
</operator>
<operatorname="operator []">
<returntype="Vector4"/>
<paramindex="0"name="index"type="int"/>
<description>
Returns the [Vector4] at index [param index]. 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.
