Strings

Strings

In SGML, to implement text into a game, you must use strings. Strings are lines of text stored within a variable which can be drawn on the screen or stored as data. Strings are always written within quotation marks. String functions in SGML allow you to check what text a string holds, the character count of a string, replace text in a string, change variables to strings, change the case of text, and so on. An example of the creation of a string is like this:

str = “Hello World!”;

To force a line break, use the # symbol within the string, like so

str = “This is line one.#This is line two.”;

To use the # symbol within the string, put a \ before it.

str “\#selfie”

All letters, digits, and symbols can be used within strings so long as your font chosen supports them. Any unsupported characters within a font will be replaced with a ▯ symbol.

str1 = “There are 2-3 items in this room! :)”
