<h1>CubeScript Console Language</h1>
|
|
|
|
<p>
|
|
Cube's console language is similar to console languages of other games (e.g. Quake), but is a bit more powerful in
|
|
that it is almost a full programming language.
|
|
</p>
|
|
|
|
<p>
|
|
What is similar to quake is the basic command structure: commands consist of the command itself, followed by any
|
|
number of arguments seperated by whitespace. you can use "" to quote strings with whitespace in them (such as the
|
|
actions in bind/alias), and whereever a command is required you can also use ; to sequence multiple commands in one.
|
|
</p>
|
|
<p>
|
|
What is new compared to quake is that you can evaluate aliases and expressions. You can substitute the value of an
|
|
alias as an argument by prefixing it with a "$" sign, i.e.: <span class="code">echo The current value of x is $x</span>
|
|
You can even substitute
|
|
the values of console variables this way, i.e $fov gives the current fov. Some aliases are set automatically, for
|
|
example $arg1 to $argN are set if you supply arguments when you execute an alias.
|
|
</p>
|
|
<p>
|
|
There are two alternative ways to "" to quote a string: () and []. They work in the same way as "", with the difference
|
|
that they can be nested infinitely, and that they may contain linefeeds (useful for larger scripts). () is different
|
|
from [] in that it evaluates the commands contained in it _before_ it evaluates the surrounding command, and substitutes
|
|
the results. () bracketed strings are called expressions, and combined with some commands made especially for
|
|
"programming", you have a minimal language. See the <a href="reference.xml#section_CubeScript">reference</a>
|
|
for information about those commands.
