PackedVector3Array¶
A packed array of Vector3s.
Description¶
An array specifically designed to hold Vector3. 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. PackedVector3Array versus Array[Vector3]). 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 Array.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, use duplicate. This is not the case for built-in properties and methods. The returned packed array of these are a copies, and changing it will not 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#. See C# API differences to GDScript for more information.

Constructor Descriptions¶
PackedVector3Array PackedVector3Array() 🔗
Constructs an empty PackedVector3Array.
PackedVector3Array PackedVector3Array(from: PackedVector3Array)
Constructs a PackedVector3Array as a copy of the given PackedVector3Array.
PackedVector3Array PackedVector3Array(from: Array)
Constructs a new PackedVector3Array. Optionally, you can pass in a generic Array that will be converted.
Note: When initializing a PackedVector3Array with elements, it must be initialized with an Array of Vector3 values:
var array = PackedVector3Array([Vector3(12, 34, 56), Vector3(78, 90, 12)])
Method Descriptions¶
Appends an element at the end of the array (alias of push_back).
void append_array(array: PackedVector3Array) 🔗
Appends a PackedVector3Array at the end of this array.
int bsearch(value: Vector3, 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, a before specifier can be passed. If false, the returned index comes after all existing entries of the value in the array.
Note: Calling bsearch 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.
void clear() 🔗
Clears the array. This is equivalent to using resize with a size of 0.
int count(value: Vector3) const 🔗
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.
PackedVector3Array duplicate() 🔗
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 with resize to create an array with a given size and initialized elements.
int find(value: Vector3, 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.
bool has(value: Vector3) const 🔗
Returns true if the array contains value.
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.
int insert(at_index: int, value: Vector3) 🔗
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()).
Returns true if the array is empty.
bool push_back(value: Vector3) 🔗
Inserts a Vector3 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. Calling resize once and assigning the new values is faster than adding new elements one by one.
void reverse() 🔗
Reverses the order of the elements in the array.
int rfind(value: Vector3, 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.
void set(index: int, value: Vector3) 🔗
Changes the Vector3 at the given index.
Returns the number of elements in the array.
PackedVector3Array slice(begin: int, end: int = 2147483647) const 🔗
Returns the slice of the PackedVector3Array, from begin (inclusive) to end (exclusive), as a new PackedVector3Array.
The absolute value of begin and end will be clamped to the array size, so the default value for end makes it slice to the size of the array by default (i.e. arr.slice(1) is a shorthand for arr.slice(1, arr.size())).
If either begin or end are negative, they will be relative to the end of the array (i.e. arr.slice(0, -2) is a shorthand for arr.slice(0, arr.size() - 2)).
void sort() 🔗
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.
PackedByteArray to_byte_array() const 🔗
Returns a PackedByteArray with each vector encoded as bytes.
Operator Descriptions¶
bool operator !=(right: PackedVector3Array) 🔗
Returns true if contents of the arrays differ.
PackedVector3Array operator *(right: Transform3D) 🔗
Returns a new PackedVector3Array with all vectors in this array inversely transformed (multiplied) by the given Transform3D transformation matrix, under the assumption that the transformation basis is orthonormal (i.e. rotation/reflection is fine, scaling/skew is not).
array * transform is equivalent to transform.inverse() * array. See Transform3D.inverse.
For transforming by inverse of an affine transformation (e.g. with scaling) transform.affine_inverse() * array can be used instead. See Transform3D.affine_inverse.
PackedVector3Array operator +(right: PackedVector3Array) 🔗
Returns a new PackedVector3Array with contents of right added at the end of this array. For better performance, consider using append_array instead.
bool operator ==(right: PackedVector3Array) 🔗
Returns true if contents of both arrays are the same, i.e. they have all equal Vector3s at the corresponding indices.
Vector3 operator [](index: int) 🔗
Returns the Vector3 at index 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.
