String

A built-in type for strings.

Description

This is the built-in string Variant type (and the one used by GDScript). Strings may contain any number of Unicode characters, and expose methods useful for manipulating and generating strings. Strings are reference-counted and use a copy-on-write approach (every modification to a string returns a new String), so passing them around is cheap in resources.

Some string methods have corresponding variations. Variations suffixed with n (countn, findn, replacen, etc.) are case-insensitive (they make no distinction between uppercase and lowercase letters). Method variations prefixed with r (rfind, rsplit, etc.) are reversed, and start from the end of the string, instead of the beginning.

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

備註

There are notable differences when using this API with C#. See C# API 與 GDScript 的不同 for more information.
