|
|
A packed array of 32-bit floating-point values.
|
|
</brief_description>
|
|
<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].

|
|
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 [param before] specifier can be passed. If [code]false[/code], the returned index comes after all existing entries of the value in the array.
|
|
[b]Note:[/b] Calling [method bsearch] on an unsorted array results in unexpected behavior.

<param index="0" name="new_size" type="int" />
|
|
<description>
|
|
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.
|
|
</description>
|
|
</method>
|
|
<method name="reverse">
|
|
<return type="void" />
|
|
<description>
|

<method name="rfind" qualifiers="const">
|
|
<return type="int" />
|
|
<param index="0" name="value" type="float" />
|
|
<param index="1" name="from" type="int" default="-1" />
|
|
<description>
|
|
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.
|
|
</description>
|
|
</method>
|
|
<method name="set">
|
|
<return type="void" />
|
|
<param index="0" name="index" type="int" />
|
|
<param index="1" name="value" type="float" />
|
|
<description>
|
|

|
|
</description>
|
|
</method>
|
|
<method name="size" qualifiers="const">
|
|
<return type="int" />
|
|
<description>
|
|
Returns the number of elements in the array.
|
|
</description>
|
|
</method>
|
|
<method name="slice" qualifiers="const">
|
|
<return type="PackedFloat32Array" />
|
|
<param index="0" name="begin" type="int" />
|
|
<param index="1" name="end" type="int" default="2147483647" />
|
|
<description>
|
|
Returns the slice of the [PackedFloat32Array], from [param begin] (inclusive) to [param end] (exclusive), as a new [PackedFloat32Array].
|
|
The absolute value of [param begin] and [param end] will be clamped to the array size, so the default value for [param end] makes it slice to the size of the array by default (i.e. [code]arr.slice(1)[/code] is a shorthand for [code]arr.slice(1, arr.size())[/code]).
|
|
If either [param begin] or [param end] are negative, they will be relative to the end of the array (i.e. [code]arr.slice(0, -2)[/code] is a shorthand for [code]arr.slice(0, arr.size() - 2)[/code]).
|
|
</description>
|
|
</method>
|
|
<method name="sort">
|
|
<return type="void" />
|
|
<description>
|
|
Sorts the elements of the array in ascending order.
|
|
</description>
|
|
</method>
|
|
<method name="to_byte_array" qualifiers="const">
|
|
<return type="PackedByteArray" />
|
|
<description>
|
|
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 [code]float32_array.size() * 4[/code].

<param index="0" name="right" type="PackedFloat32Array" />
|
|
<description>
|
|
Returns a new [PackedFloat32Array] with contents of [param right] added at the end of this array. For better performance, consider using [method append_array] instead.
|
|
</description>
|
|
</operator>
|
|
<operator name="operator ==">
|
|
<return type="bool" />
|
|
<param index="0" name="right" type="PackedFloat32Array" />
|
|
<description>
|
|
Returns [code]true[/code] if contents of both arrays are the same, i.e. they have all equal floats at the corresponding indices.
|
|
</description>
|
|
</operator>
|
|
<operator name="operator []">
|
|
<return type="float" />
|
|
<param index="0" name="index" type="int" />
|
|
<description>
|
|
Returns the [float] at index [param 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.
