you access the console by pressing "~" at any time

Console variable types

There are six types of cvars: Boolean, Integer, Float, String, Colour and Flag.

boolean

This type of variable represents a yes/no or on/off value. It can only be set to true or false. As shorthand, setting a boolean variable to 0 will set it to false, and setting it to anything non-zero will set it to true.

integer

This is an ordinary number without a decimal point. For example, 1 is an integer, but 1.2 is not.

float

This is an ordinary number that can have a decimal point.

string

This is a series of text characters enclosed in quotes: For example, "Felix loitered lecherously on the lot" is a string. If you removed the quotes around it, then it would not be a string. If you need to use quotes inside a string, preface it with a backslash.

Are you "The One" of old?

would be written like this as a string:

"Are you \"The One\" of old?"

colour

This type of variable is a series of three hexadecimal numbers representing the amounts of red, green, and blue (in that order) in a color. For example, pure red would be represented as "ff 00 00". As a shorthand, you can set a color variable with one of several color names, and the RGB values will be set for you.

= flag

This type of variable mirrors a setting in dmflags or dmflags2. Setting its value will set the corresponding value in one of those variables, and getting its value will get the corresponding value from one of the other two variables. This is designed to make using dmflags easier, because you don't have to memorize any numbers.
