PackedFloat64Array¶
A packed array of 64-bit floating-point values.
Description¶
An array specifically designed to hold 64-bit floating-point values (double). 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.
Note
There are notable differences when using this API with C#. See C# API differences to GDScript for more information.

Constructor Descriptions¶
PackedFloat64Array PackedFloat64Array ( )
Constructs an empty PackedFloat64Array.
PackedFloat64Array PackedFloat64Array ( PackedFloat64Array from )
Constructs a PackedFloat64Array as a copy of the given PackedFloat64Array.
PackedFloat64Array PackedFloat64Array ( Array from )
Constructs a new PackedFloat64Array. Optionally, you can pass in a generic Array that will be converted.
Method Descriptions¶
Appends an element at the end of the array (alias of push_back).
void append_array ( PackedFloat64Array array )
Appends a PackedFloat64Array at the end of this array.
int bsearch ( float 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: @GDScript.NAN doesn't behave the same as other numbers. 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 ( float value ) const
Returns the number of times an element is in the array.
Note: @GDScript.NAN doesn't behave the same as other numbers. Therefore, the results from this method may not be accurate if NaNs are included.
PackedFloat64Array duplicate ( )
Creates a copy of the array, and returns it.
void fill ( float 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 ( float 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: @GDScript.NAN doesn't behave the same as other numbers. Therefore, the results from this method may not be accurate if NaNs are included.
bool has ( float value ) const
Returns true
if the array contains value
.
Note: @GDScript.NAN doesn't behave the same as other numbers. Therefore, the results from this method may not be accurate if NaNs are included.
int insert ( int at_index, float 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 ( float value )
Appends an element at the end of the array.
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. 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 ( float 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: @GDScript.NAN doesn't behave the same as other numbers. Therefore, the results from this method may not be accurate if NaNs are included.
void set ( int index, float value )
Changes the float at the given index.
int size ( ) const
Returns the number of elements in the array.
PackedFloat64Array slice ( int begin, int end=2147483647 ) const
Returns the slice of the PackedFloat64Array, from begin
(inclusive) to end
(exclusive), as a new PackedFloat64Array.
The absolute value of
