The same is done for `Vector` (and thus `Packed*Array`). `begin` and `end` can now take any value and will be clamped to `[-size(), size()]`. Negative values are a shorthand for indexing the array from the last element upward. `end` is given a default `INT_MAX` value (which will be clamped to `size()`) so that the `end` parameter can be omitted to go from `begin` to the max size of the array. This makes `slice` works similarly to numpy's and JavaScript's.

|
<description>
|
|
An [Array] specifically designed to hold [Vector2]. Packs data tightly, so it saves memory for large array sizes.

|
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 [code]before[/code] 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.

<description>
|

<description>
|

|
|
</description>
|
|
</method>
|
|
<method name="size" qualifiers="const">
|
|
<return type="int" />
|
|
<description>
|
|
Returns the number of elements in the array.
|
|
</description>
|

</method>
|
|
<method name="slice" qualifiers="const">
|
|
<return type="PackedVector2Array" />
|
|
<argument index="0" name="begin" type="int" />
|
|
<argument index="1" name="end" type="int" default="2147483647" />
|
|
<description>
|
|
Returns the slice of the [PackedVector2Array], from [code]begin[/code] (inclusive) to [code]end[/code] (exclusive), as a new [PackedVector2Array].
|
|
The absolute value of [code]begin[/code] and [code]end[/code] will be clamped to the array size, so the default value for [code]end[/code] 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 [code]begin[/code] or [code]end[/code] 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>
