Server variables

Variable Information

Out of the box, Odamex will function nearly identical to how Doom did when it was originally released. However, with two decades of progress, Odamex has given players and server administrators a number of options that allow for a wide range of play types. A wide variety of sample configurations are provided with the Odamex installation in the "config-samples" directory. There are a number of terms you should know when dealing with the variables listed below.

Value Types

• Boolean - A binary variable. These variables only respond to the values 0 and 1. Imagine it as a light switch where 0 is off and 1 is on.
• Float - A number value that can have a variety of ranges. For the purposes of Odamex, these values are typically represented in a decimal form (e.g. "1.5")
• Integer - A whole number value, no decimals.
• String - A non-numerical value, usually a word or phrase.

Variable Types

• Archived - The value for this variable will be saved and stored to the config file if it is changed.
• Latched - A change to this type of variable will not take effect until after a map change.
• Server Info - The values of these variables are sent to clients and launchers.
• Read-Only - These variables cannot be changed. Used to output information.
