This script allows you to automatically save your maps every X minutes, which can be set. This is useful if you are making a map and something goes wrong, leaving you without a recent save.
To use it bind toggleAutosave to a key of your choosing
For example: /bind P toggleAutosave
You can also set the amount of time between saves. Do this by setting the variable saveinterval.
For example (again): /saveinterval = 10
That would set it to save every 10 minutes.
The last option is the autosavemapname option. It controls the name your map is saved under when autosaving.
Example: /autosavemapname = testingmap
Save the script as autosave.cfg in your sauerbraten dir and add "exec autosave.cfg" to your autoexec.cfg
