== Problem ==

Many configuration options for BF2 are read from <code>.con</code> files that can be edited by the server administrator. You are writing a cool Python expansion for BF2, but for your code to work you need to know the values of some of these configuration parameters; for example, <code>sv.autoDemoHook</code>.

== Solution ==

It turns out that if you type the name of a configuration variable into the server console window, the server will respond with the value of that variable, with a newline character appended to it for good measure. You can use the [[Object_Reference#RCon_Methods|<code>host.rcon_invoke</code>]] method from within your Python program to simulate the same thing, and then use the string <code>strip()</code> method to get rid of the extraneous newline.

The following function encapsulates this approach:

<pre>
def serverConfig(variableName):
return host.rcon_invoke(variableName).strip()
</pre>

To use it, just call the function:

<pre> hook = serverConfig("sv.autoDemoHook") # Sets hook to "adminutils/demo/rotate_demo.exe" </pre>

CAUTION: this <code>serverConfig</code> function always returns a string value; if the variable you want to read is numeric (for example, <code>sv.serverPort</code>) you will need to apply <code>int()</code> or a related function to convert the returned string to a numeric value:

<pre> port = int(serverConfig("sv.serverPort")) # Sets port to numeric 16567 </pre>

== Discussion ==

This technique only works to read standard server configuration variables; the BF2 engine won't allow you to specify arbitrary custom configuration variables in <code>.con</code> files, so you can't use it for that purpose. See [[Cookbook:Easy_Custom_Config_Variables|Easy Custom Config Variables]] for an alternative that would work for custom variables.
