Sets the value of a variable
View list of data type meanings
long SetVariable(BSTR VariableName, BSTR Contents);
Sets the contents of a variable. If the named variable already exists the contents are replaced. If the variable doesn't exist it is created. Variables are contained in the "world" configuration, and saved when the world is saved. You can use variables to "remember" data from one session of MUSHclient to the next.
* Rules for names
Names of triggers, aliases, timers and variables must follow these rules:
a. Start with a letter (A-Z)
b. Be followed by letters (A-Z), numbers (0-9) or the underscore character (_)
Please note that the following characters will not be handled correctly:
* The byte value hex 00 (otherwise known as 0x00 or null). This is used as a string terminator in MUSHclient, and attempts to imbed 0x00 values into variables will result in the variable being terminated at the 0x00 position.
* Carriage-return (hex 0D or 0x0D) and line-feeds (hex 0A or 0x0A). You can use these internally however you like, however when they are read from a plugin state file, or a MUSHclient world file, carriage returns are dropped, and line-feeds are converted to the sequence 0x0D 0x0A (carriage-return followed by linefeed). This is not normally a problem - because line breaks are usually stored as carriage-return/linefeed, and the reading process effectively will read them back in as that. However individual carriage-returns or linefeeds will not be read back in correctly.
If you are planning to use variables to store "binary" data - that is, data that can have all 256 possible character values, you are advised to convert them to base-64 encoded strings (using Base64Encode) when saving them, and conver them back (using Base64Decode) when loading them. Also be aware that only the Lua version of the base 64 encoding (utils.base64encode and utils.base64decode) will correctly handle the 0x00 value.
world.SetVariable "MyName", "Nick Gammon"
world.SetVariable("MyName", "Nick Gammon");
$world->SetVariable("MyName", "Nick Gammon");
world.SetVariable("MyName", "Nick Gammon")
SetVariable ("MyName", "Nick Gammon")
