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 pass a String to methods expecting a StringName and it will be automatically converted (often at compile time), but in rare cases you can construct a StringName ahead of time with the StringName constructor or, in GDScript, the literal syntax &"example". Manually constructing a StringName allows you to control when the conversion from String occurs or to use the literal and prevent conversions entirely.
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.
Constructs an empty StringName.
Constructs a StringName as a copy of the given StringName.
Creates a new StringName from the given String. In GDScript, StringName("example") is equivalent to &"example".
Returns true if this StringName is not equivalent to the given String.
Returns true if the StringName and right do not refer to the same name. Comparisons between StringNames are much faster than regular String comparisons.
Formats the StringName, replacing the placeholders with one or more parameters, returning a String. To pass multiple parameters, right needs to be an Array.
For more information, see the GDScript format strings tutorial.
Note: In C#, this operator is not available. Instead, see how to interpolate strings with "$".
Appends right at the end of this StringName, returning a String. This is also known as a string concatenation.
Appends right at the end of this StringName, returning a String. This is also known as a string concatenation.
Returns true if the left StringName's pointer comes before right. Note that this will not match their Unicode order.
Returns true if the left StringName's pointer comes before right or if they are the same. Note that this will not match their Unicode order.
Returns true if this StringName is equivalent to the given String.
Returns true if the StringName and right refer to the same name. Comparisons between StringNames are much faster than regular String comparisons.
Returns true if the left StringName's pointer comes after right. Note that this will not match their Unicode order.
Returns true if the left StringName's pointer comes after right or if they are the same. Note that this will not match their Unicode order.
Returns true if the string begins with the given text. See also ends_with.
Returns an array containing the bigrams (pairs of consecutive characters) of this string.
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.
Returns a copy of the string with special characters escaped using the C language standard.
Returns a copy of the string with escaped characters replaced by their meanings. Supported escape sequences are \', \", \\, \a, \b, \f, \n, \r, \t, \v.
Note: Unlike the GDScript parser, this method doesn't support the \uXXXX escape sequence.
Changes the appearance of the string: replaces underscores (_) with spaces, adds spaces before uppercase letters in the middle of a word, converts all letters to lowercase, then converts the first one and each one following a space to uppercase.
Performs a case-sensitive comparison to another string. Returns -1 if less than, 1 if greater than, or 0 if equal. "Less than" and "greater than" are determined by the Unicode code points of each string, which roughly matches the alphabetical order.
With different string lengths, returns 1 if this string is longer than the to string, or -1 if shorter. Note that the length of empty strings is always 0.
To get a bool result from a string comparison, use the == operator instead. See also nocasecmp_to, naturalcasecmp_to, and naturalnocasecmp_to.
Returns true if the string contains what. In GDScript, this corresponds to the in operator.
If you need to know where what is within the string, use find.
Returns the number of occurrences of the substring what between from and to positions. If to is 0, the search continues until the end of the string.
Returns the number of occurrences of the substring what between from and to positions, ignoring case. If to is 0, the search continues until the end of the string.
Returns a copy of the string with indentation (leading tabs and spaces) removed. See also indent to add indentation.
Returns true if the string ends with the given text. See also begins_with.
Returns a string with chars characters erased starting from position. If chars goes beyond the string's length given the specified position, fewer characters will be erased from the returned string. Returns an empty string if either position or chars is negative. Returns the original string unmodified if chars is 0.
Returns the index of the first occurrence of what in this string, or -1 if there are none. The search's start can be specified with from, continuing to the end of the string.
Note: If you just want to know whether the string contains what, use contains. In GDScript, you may also use the in operator.
Returns the index of the first case-insensitive occurrence of what in this string, or -1 if there are none. The starting search index can be specified with from, continuing to the end of the string.
Formats the string by replacing all occurrences of placeholder with the elements of values.
values can be a Dictionary or an Array. Any underscores in placeholder will be replaced with the corresponding keys in advance. Array elements use their index as keys.
Some additional handling is performed when values is an Array. If placeholder does not contain an underscore, the elements of the values array will be used to replace one occurrence of the placeholder in order; If an element of values is another 2-element array, it'll be interpreted as a key-value pair.
See also the GDScript format string tutorial.
Note: In C#, it's recommended to interpolate strings with "$", instead.
If the string is a valid file path, returns the base directory name.
If the string is a valid file path, returns the full file path, without the extension.
If the string is a valid file name or path, returns the file extension without the leading period (.). Otherwise, returns an empty string.
If the string is a valid file path, returns the file name, including the extension.
Splits the string using a delimiter and returns the substring at index slice. Returns an empty string if the slice does not exist.
This is faster than split, if you only need one substring.
Example:
Returns the total number of slices when the string is split with the given delimiter (see split).
Splits the string using a Unicode character with code delimiter and returns the substring at index slice. Returns an empty string if the slice does not exist.
This is faster than split, if you only need one substring.
Returns the 32-bit hash value representing the string's contents.
Note: Strings with equal hash values are not guaranteed to be the same, as a result of hash collisions. On the contrary, strings with different hash values are guaranteed to be different.
Decodes a hexadecimal string as a PackedByteArray.
Converts the string representing a hexadecimal number into an int. The string may be optionally prefixed with "0x", and an additional - prefix for negative numbers.
Indents every line of the string with the given prefix. Empty lines are not indented. See also dedent to remove indentation.
For example, the string can be indented with two tabulations using "\t\t", or four spaces using " ".
Inserts what at the given position in the string.
Returns true if the string is a path to a file or directory, and its starting point is explicitly defined. This method is the opposite of is_relative_path.
This includes all paths starting with "res://", "user://", "C:\", "/", etc.
Returns true if the string's length is 0 (""). See also length.
Returns true if the string is a path, and its starting point is dependent on context. The path could begin from the current directory, or the current Node (if the string is derived from a NodePath), and may sometimes be prefixed with "./". This method is the opposite of is_absolute_path.
Returns true if all characters of this string can be found in text in their original order.
Returns true if all characters of this string can be found in text in their original order, ignoring case.
Returns true if this string does not contain characters that are not allowed in file names (: / \ ? * " | % < >).
Returns true if this string represents a valid floating-point number. A valid float may contain only digits, one decimal point (.), and the exponent letter (e). It may also be prefixed with a positive (+) or negative (-) sign. Any valid integer is also a valid float (see is_valid_int). See also to_float.
Returns true if this string is a valid hexadecimal number. A valid hexadecimal number only contains digits or letters A to F (either uppercase or lowercase), and may be prefixed with a positive (+) or negative (-) sign.
If with_prefix is true, the hexadecimal number needs to prefixed by "0x" to be considered valid.
Returns true if this string is a valid color in hexadecimal HTML notation. The string must be a hexadecimal value (see is_valid_hex_number) of either 3, 4, 6 or 8 digits, and may be prefixed by a hash sign (#). Other HTML notations for colors, such as names or hsl(), are not considered valid. See also Color.html.
Returns true if this string is a valid identifier. A valid identifier may contain only letters, digits and underscores (_), and the first character may not be a digit.
Returns true if this string represents a valid integer. A valid integer only contains digits, and may be prefixed with a positive (+) or negative (-) sign. See also to_int.
Returns true if this string represents a well-formatted IPv4 or IPv6 address. This method considers reserved IP addresses such as "0.0.0.0" and "ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff" as valid.
Returns the concatenation of parts' elements, with each element separated by the string calling this method. This method is the opposite of split.
Example:
Returns a copy of the string with special characters escaped using the JSON standard. Because it closely matches the C standard, it is possible to use c_unescape to unescape the string, if necessary.
Returns the first length characters from the beginning of the string. If length is negative, strips the last length characters from the string's end.
Returns the number of characters in the string. Empty strings ("") always return 0. See also is_empty.
Formats the string to be at least min_length long by adding characters to the left of the string, if necessary. See also rpad.
Removes a set of characters defined in chars from the string's beginning. See also rstrip.
Note: chars is not a prefix. Use trim_prefix to remove a single prefix, rather than a set of characters.
Does a simple expression match (also called "glob" or "globbing"), where * matches zero or more arbitrary characters and ? matches any single character except a period (.). An empty string or empty expression always evaluates to false.
Does a simple case-insensitive expression match, where * matches zero or more arbitrary characters and ? matches any single character except a period (.). An empty string or empty expression always evaluates to false.
Returns the MD5 hash of the string as a PackedByteArray.
Performs a case-sensitive, natural order comparison to another string. Returns -1 if less than, 1 if greater than, or 0 if equal. "Less than" or "greater than" are determined by the Unicode code points of each string, which roughly matches the alphabetical order.
When used for sorting, natural order comparison orders sequences of numbers by the combined value of each digit as is often expected, instead of the single digit's value. A sorted sequence of numbered strings will be ["1", "2", "3", ...], not ["1", "10", "2", "3", ...].
With different string lengths, returns 1 if this string is longer than the to string, or -1 if shorter. Note that the length of empty strings is always 0.
To get a bool result from a string comparison, use the == operator instead. See also naturalnocasecmp_to, nocasecmp_to, and casecmp_to.
Performs a case-insensitive, natural order comparison to another string. Returns -1 if less than, 1 if greater than, or 0 if equal. "Less than" or "greater than" are determined by the Unicode code points of each string, which roughly matches the alphabetical order. Internally, lowercase characters are converted to uppercase for the comparison.

Concatenates file at the end of the string as a subpath, adding / if necessary.
Example: "this/is".path_join("path") == "this/is/path".
Repeats this string a number of times. count needs to be greater than 0. Otherwise, returns an empty string.
Replaces all occurrences of what inside the string with the given forwhat.
Replaces all case-insensitive occurrences of what inside the string with the given forwhat.
Returns the copy of this string in reverse order.
Returns the index of the last occurrence of what in this string, or -1 if there are none. The search's start can be specified with from, continuing to the beginning of the string. This method is the reverse of find.
Returns the index of the last case-insensitive occurrence of what in this string, or -1 if there are none. The starting search index can be specified with from, continuing to the beginning of the string. This method is the reverse of findn.
Returns the last length characters from the end of the string. If length is negative, strips the first length characters from the string's beginning.
Formats the string to be at least min_length long, by adding characters to the right of the string, if necessary. See also lpad.
Splits the string using a delimiter and returns an array of the substrings, starting from the end of the string. The splits in the returned array appear in the same order as the original string. If delimiter is an empty string, each substring will be a single character.
If allow_empty is false, empty strings between adjacent delimiters are excluded from the array.
If maxsplit is greater than 0, the number of splits may not exceed maxsplit. By default, the entire string is split, which is mostly identical to split.
Example:
Removes a set of characters defined in chars from the string's end. See also lstrip.
Note: chars is not a suffix. Use trim_suffix to remove a single suffix, rather than a set of characters.
Returns the SHA-1 hash of the string as a PackedByteArray.
Returns the SHA-256 hash of the string as a PackedByteArray.
Returns the similarity index (Sorensen-Dice coefficient) of this string compared to another. A result of 1.0 means totally similar, while 0.0 means totally dissimilar.
If the string is a valid file path, converts the string into a canonical path. This is the shortest possible path, without "./", and all the unnecessary ".." and "/".
Splits the string using a delimiter and returns an array of the substrings. If delimiter is an empty string, each substring will be a single character. This method is the opposite of join.
If allow_empty is false, empty strings between adjacent delimiters are excluded from the array.
If maxsplit is greater than 0, the number of splits may not exceed maxsplit. By default, the entire string is split.
Example:
Note: If you only need one substring from the array, consider using get_slice which is faster. If you need to split strings with more complex rules, use the RegEx class instead.
Splits the string into floats by using a delimiter and returns a PackedFloat64Array.
If allow_empty is false, empty or invalid float conversions between adjacent delimiters are excluded.
Strips all non-printable characters from the beginning and the end of the string. These include spaces, tabulations (\t), and newlines (\n \r).
If left is false, ignores the string's beginning. Likewise, if right is false, ignores the string's end.
Strips all escape characters from the string. These include all non-printable control characters of the first page of the ASCII table (values from 0 to 31), such as tabulation (\t) and newline (\n, \r) characters, but not spaces.
Returns part of the string from the position from with length len. If len is -1 (as by default), returns the rest of the string starting from the given position.
Converts the string to an ASCII/Latin-1 encoded PackedByteArray. This method is slightly faster than to_utf8_buffer, but replaces all unsupported characters with spaces.
Returns the string converted to camelCase.
Converts the string representing a decimal number into a float. This method stops on the first non-number character, except the first decimal point (.) and the exponent letter (e). See also is_valid_float.
Converts the string representing an integer number into an int. This method removes any non-number character and stops at the first decimal point (.). See also is_valid_int.
Returns the string converted to lowercase.
Returns the string converted to PascalCase.
Returns the string converted to snake_case.
Note: Numbers followed by a single letter are not separated in the conversion to keep some words (such as "2D") together.
Returns the string converted to UPPERCASE.
Converts the string to a UTF-8 encoded PackedByteArray. This method is slightly slower than to_ascii_buffer, but supports all UTF-8 characters. For most cases, prefer using this method.
Converts the string to a UTF-16 encoded PackedByteArray.
Converts the string to a UTF-32 encoded PackedByteArray.
Converts the string to a wide character (wchar_t, UTF-16 on Windows, UTF-32 on other platforms) encoded PackedByteArray.
Removes the given prefix from the start of the string, or returns the string unchanged.
Removes the given suffix from the end of the string, or returns the string unchanged.
Returns the character code at position at.
