PackedVector4Array
A packed array of Vector4s.
Description
An array specifically designed to hold Vector4. 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. PackedVector4Array versus Array[Vector4]). 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. In these cases the returned packed array is a copy, and changing it will not affect the original value. To update a built-in property of this type, modify the returned array and then assign it to the property again.
Constructors
PackedVector4Array PackedVector4Array()
PackedVector4Array PackedVector4Array()Constructs an empty PackedVector4Array.
PackedVector4Array PackedVector4Array(PackedVector4Array from)
PackedVector4Array PackedVector4Array(PackedVector4Array from)Constructs a PackedVector4Array as a copy of the given PackedVector4Array.
PackedVector4Array PackedVector4Array(Array from)
PackedVector4Array PackedVector4Array(Array from)Constructs a new PackedVector4Array. Optionally, you can pass in a generic Array that will be converted. Note: When initializing a PackedVector4Array with elements, it must be initialized with an Array of Vector4 values:
var array = PackedVector4Array([Vector4(12, 34, 56, 78), Vector4(90, 12, 34, 56)])
Methods
bool append(Vector4 value)
bool append(Vector4 value)Appends an element at the end of the array (alias of push_back()).
void append_array(PackedVector4Array array)
PackedVector4Array array)Appends a PackedVector4Array at the end of this array.
int bsearch(Vector4 value, bool before = true)
int bsearch(Vector4 value, bool before = 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(Vector4 value) const
int count(Vector4 value) constReturns 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.
PackedVector4Array duplicate()
PackedVector4Array duplicate()Creates a copy of the array, and returns it.
bool erase(Vector4 value)
bool erase(Vector4 value)Removes the first occurrence of a value from the array and returns true. If the value does not exist in the array, nothing happens and false is returned. To remove an element by index, use remove_at() instead. 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 fill(Vector4 value)
Vector4 value)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(Vector4 value, int from = 0) const
int find(Vector4 value, int from = 0) constSearches 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.
Vector4 get(int index) const
Vector4 get(int index) constReturns the Vector4 at the given index in the array. If index out-of-bounds or negative, this method fails and returns Vector4(0, 0, 0, 0). This method is similar (but not identical) to the [] operator. Most notably, when this method fails, it doesn't pause project execution if run from the editor.
bool has(Vector4 value) const
bool has(Vector4 value) constReturns 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(int at_index, Vector4 value)
int insert(int at_index, Vector4 value)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()).
bool is_empty() const
bool is_empty() constReturns true if the array is empty.
bool push_back(Vector4 value)
bool push_back(Vector4 value)Inserts a Vector4 at the end.
void remove_at(int index)
int index)Removes an element from the array by index.
int resize(int new_size)
int resize(int new_size)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. Returns OK on success, or one of the following Error constants if this method fails: ERR_INVALID_PARAMETER if the size is negative, or ERR_OUT_OF_MEMORY if allocations fail. Use size() to find the actual size of the array after resize.
void reverse()
Reverses the order of the elements in the array.
int rfind(Vector4 value, int from = -1) const
int rfind(Vector4 value, int from = -1) constSearches 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(int index, Vector4 value)
int index, Vector4 value)Changes the Vector4 at the given index.
int size() const
int size() constReturns the number of elements in the array.
PackedVector4Array slice(int begin, int end = 2147483647) const
PackedVector4Array slice(int begin, int end = 2147483647) constReturns the slice of the PackedVector4Array, from begin (inclusive) to end (exclusive), as a new PackedVector4Array. 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
PackedByteArray to_byte_array() constReturns a PackedByteArray with each vector encoded as bytes.
Operators
bool operator !=(PackedVector4Array right)
bool operator !=(PackedVector4Array right)Returns true if contents of the arrays differ.
PackedVector4Array operator +(PackedVector4Array right)
PackedVector4Array operator +(PackedVector4Array right)Returns a new PackedVector4Array with contents of right added at the end of this array. For better performance, consider using append_array() instead.
bool operator ==(PackedVector4Array right)
bool operator ==(PackedVector4Array right)Returns true if contents of both arrays are the same, i.e. they have all equal Vector4s at the corresponding indices.
Vector4 operator [](int index)
Vector4 operator [](int index)Returns the Vector4 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.
