Class PackedVector3Array
A packed array of Vector3s.
Remarks
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.
Constructors
PackedVector3Array
Constructs an empty PackedVector3Array.
PackedVector3Array PackedVector3Array
PackedVector3Array(PackedVector3Array)
Constructs a PackedVector3Array as a copy of the given PackedVector3Array.
PackedVector3Array PackedVector3Array(PackedVector3Array from)
Parameters
from
PackedVector3Array
PackedVector3Array(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)])
PackedVector3Array PackedVector3Array(Array from)
Parameters
from
Array
Methods
append(Vector3)
Appends an element at the end of the array (alias of PackedVector3Array.push_back).
bool append(Vector3 value)
Parameters
value
Vector3
append_array(PackedVector3Array)
Appends a PackedVector3Array at the end of this array.
void append_array(PackedVector3Array array)
Parameters
array
PackedVector3Array
bsearch(Vector3, bool)
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 PackedVector3Array.bsearch on an unsorted array results in unexpected behavior.
Note: Vectors with 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 bsearch(Vector3 value, bool before)
Parameters
clear
Clears the array. This is equivalent to using PackedVector3Array.resize with a size of 0
.
void clear
count(Vector3)
Qualifiers: const
Returns the number of times an element is in the array.
Note: Vectors with 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 count(Vector3 value)
Parameters
value
Vector3
duplicate
Creates a copy of the array, and returns it.
PackedVector3Array duplicate
fill(Vector3)
Assigns the given value to all elements in the array. This can typically be used together with PackedVector3Array.resize to create an array with a given size and initialized elements.
void fill(Vector3 value)
Parameters
value
Vector3
find(Vector3, int)
Qualifiers: 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 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 find(Vector3 value, int from)
Parameters
get(int)
Qualifiers: const
Returns the Vector3 at the given index
in the array. This is the same as using the []
operator (array[index]
).
Vector3 get(int index)
Parameters
index
int
has(Vector3)
Qualifiers: const
Returns true
if the array contains value
.
Note: Vectors with 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(Vector3 value)
Parameters
value
Vector3
insert(int, 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()
).
int insert(int at_index, Vector3 value)
Parameters
is_empty
Qualifiers: const
Returns true
if the array is empty.
bool is_empty
push_back(Vector3)
Inserts a Vector3 at the end.
bool push_back(Vector3 value)
Parameters
value
Vector3
remove_at(int)
Removes an element from the array by index.
void remove_at(int index)
Parameters
index
int
resize(int)
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 PackedVector3Array.resize once and assigning the new values is faster than adding new elements one by one.
int resize(int new_size)
Parameters
new_size
int
reverse
Reverses the order of the elements in the array.
void reverse
rfind(Vector3, int)
Qualifiers: 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 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 rfind(Vector3 value, int from)
Parameters
set(int, Vector3)
Changes the Vector3 at the given index.
void set(int index, Vector3 value)
Parameters
size
Qualifiers: const
Returns the number of elements in the array.
int size
slice(int, int)
Qualifiers: 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)
).
PackedVector3Array slice(int begin, int end)
Parameters
sort
Sorts the elements of the array in ascending order.
Note: Vectors with 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 sort
to_byte_array
Qualifiers: const
Returns a PackedByteArray with each vector encoded as bytes.
PackedByteArray to_byte_array
Operators
!= (PackedVector3Array)
Returns true
if contents of the arrays differ.
bool != (PackedVector3Array right)
Parameters
right
PackedVector3Array
* (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 inverse.
For transforming by inverse of an affine transformation (e.g. with scaling) transform.affine_inverse() * array
can be used instead. See affine_inverse.
PackedVector3Array * (Transform3D right)
Parameters
right
Transform3D
+ (PackedVector3Array)
Returns a new PackedVector3Array with contents of right
added at the end of this array. For better performance, consider using PackedVector3Array.append_array instead.
PackedVector3Array + (PackedVector3Array right)
Parameters
right
PackedVector3Array
== (PackedVector3Array)
Returns true
if contents of both arrays are the same, i.e. they have all equal Vector3s at the corresponding indices.
bool == (PackedVector3Array right)
Parameters
right
PackedVector3Array
[] (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.
Vector3 [] (int index)
Parameters
index
int
