PackedVector3Array¶
A packed array of Vector3s.
描述¶
An array specifically designed to hold Vector3. Packs data tightly, so it saves memory for large array sizes.
备注
There are notable differences when using this API with C#. See C# API 与 GDScript 的差异 for more information.

Constructor Descriptions¶
PackedVector3Array PackedVector3Array ( )
Constructs an empty PackedVector3Array.
PackedVector3Array PackedVector3Array ( PackedVector3Array from )
Constructs a PackedVector3Array as a copy of the given PackedVector3Array.
PackedVector3Array PackedVector3Array ( Array from )
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 ( PackedVector3Array array )
Appends a PackedVector3Array at the end of this array.
int bsearch ( Vector3 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 ( Vector3 value ) 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.
void fill ( Vector3 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 ( Vector3 value, int from=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 ( Vector3 value ) 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 ( int at_index, Vector3 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
Returns true if the array is empty.
bool push_back ( Vector3 value )
Inserts a Vector3 at the end.
void remove_at ( int index )
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.
void reverse ( )
Reverses the order of the elements in the array.
int rfind ( Vector3 value, int from=-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 ( int index, Vector3 value )
Changes the Vector3 at the given index.
int size ( ) const
Returns the number of elements in the array.
PackedVector3Array slice ( int begin, int end=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 != ( PackedVector3Array right )
Returns true if contents of the arrays differ.
PackedVector3Array operator * ( Transform3D right )
Transforms (multiplies) all vectors in the array by the Transform3D matrix.
PackedVector3Array operator + ( PackedVector3Array right )
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 == ( PackedVector3Array right )
Returns true if contents of both arrays are the same, i.e. they have all equal Vector3s at the corresponding indices.
Vector3 operator [] ( int index )
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.
