Packs data tightly, so it saves memory for large array sizes. + [b]Differences between packed arrays, typed arrays, and untyped arrays:[/b] Packed arrays are generally faster to iterate on and modify compared to a typed array of the same type (e.g. [PackedVector3Array] versus [code]Array[Vector2][/code]). Also, packed arrays consume less memory. As a downside, packed arrays are less flexible as they don't offer as many convenience methods such as [method Array.map]. Typed arrays are in turn faster to iterate on and modify than untyped arrays. + [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. </description> <tutorials> - <link title="2D Navigation Astar Demo">https://godotengine.org/asset-library/asset/519</link> + <link title="Grid-based Navigation with AStarGrid2D Demo">https://godotengine.org/asset-library/asset/2723</link> </tutorials> <constructors> <constructor name="PackedVector2Array"> |
