Packs data tightly, so it saves memory for large array sizes. If you only need to pack 32-bit floats tightly, see [PackedFloat32Array] for a more memory-friendly alternative. + [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. [PackedFloat64Array] versus [code]Array[float][/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> </tutorials> |
