PackedFloat32Array

A packed array of 32-bit floating-point values.

Description

An array specifically designed to hold 32-bit floating-point values (float). Packs data tightly, so it saves memory for large array sizes.

If you need to pack 64-bit floats tightly, see PackedFloat64Array.

Constructor Descriptions

Constructs an empty PackedFloat32Array.


Constructs a PackedFloat32Array as a copy of the given PackedFloat32Array.


Constructs a new PackedFloat32Array. 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).


Appends a PackedFloat32Array at the end of this array.


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.


  • void clear ( )

Clears the array. This is equivalent to using resize with a size of 0.


Returns the number of times an element is in the array.


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.


Searches the array for a value and returns its index or -1 if not found. Optionally, the initial search index can be passed.


Returns true if the array contains 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.


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.


  • void reverse ( )

Reverses the order of the elements in the array.


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.


Changes the float at the given index.


  • int size ( ) const

Returns the number of elements in the array.


Returns the slice of the PackedFloat32Array, from begin (inclusive) to end (exclusive), as a new PackedFloat32Array.

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.


Returns a copy of the data converted to a PackedByteArray, where each element have been encoded as 4 bytes.

The size of the new array will be float32_array.size() * 4.

Operator Descriptions

Returns true if contents of the arrays differ.


Returns a new PackedFloat32Array with contents of right added at the end of this array. For better performance, consider using append_array instead.


Returns true if contents of both arrays are the same, i.e. they have all equal floats at the corresponding indices.


Returns the float 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.

Note that float type is 64-bit, unlike the values stored in the array.
