StringName

A built-in type for unique strings.

Description

StringNames are immutable strings designed for general-purpose representation of unique names (also called "string interning"). Two StringNames with the same value are the same object. Comparing them is extremely fast compared to regular Strings.

You will usually just pass a String to methods expecting a StringName and it will be automatically converted, but you may occasionally want to construct a StringName ahead of time with the StringName constructor or, in GDScript, the literal syntax &"example".

See also NodePath, which is a similar concept specifically designed to store pre-parsed scene tree paths.

All of String's methods are available in this class too. They convert the StringName into a string, and they also return a string. This is highly inefficient and should only be used if the string is desired.

Note: In a boolean context, a StringName will evaluate to false if it is empty (StringName("")). Otherwise, a StringName will always evaluate to true. The not operator cannot be used. Instead, is_empty should be used to check for empty StringNames.

Constructor Descriptions

StringName StringName ( )

Constructs an empty StringName.


StringName StringName ( StringName from )

Constructs a StringName as a copy of the given StringName.


StringName StringName ( String from )

Creates a new StringName from the given String. In GDScript, StringName("example") is equivalent to &"example".


Method Descriptions

bool begins_with ( String text ) const

Returns true if the string begins with the given text. See also ends_with.


PackedStringArray bigrams ( ) const

Returns an array containing the bigrams (pairs of consecutive characters) of this string.

print("Get up!".bigrams()) # Prints ["Ge", "et", "t ", " u", "up", "p!"]

int bin_to_int ( ) const

Converts the string representing a binary number into an int. The string may optionally be prefixed with "0b", and an additional - prefix for negative numbers.
