How take a screenshot ?

You want to take a proof /screenshot on the server , it's possible few methods to do it exist.
I give you only 2-3 :

* Take a screenshot by use one command on the server :
In the console write this : /autoscreenshot --> your image will be in your game folder then "screenshots" the name of the files will be a default name which will contain ( the name of the map , time and date ).

You can also take and save it with a name that you want :
exemple : /autoscreenshot 1 or /autoscreenshot party on the server hahah :=)

* You can also set a key to take a screenshot , where and how do it ?
It's easy don't worry , In the Main Menu go to "Options" then "Controls", in the "Miscellaneous" section you will see a place to select a key to "Take Screenshot".
You will find the screenshots in your folder game , maybe in the mod folder , exemple "N!tmod" --> Screenshots.
