can you tell me how to take a screenshot in game because I don't know how
What I do is use the "Print Screen" button.
Assuming you use Windows, just press "Print Screen", open up MS Paint (or some other art program), and paste it.
What if you use a Mac
Then, as previously stated, may God have mercy on your soul.
In all seriousness, though, press Command-Shift-3, and it will save a screenshot to your desktop. Alternatively, to take a screenshot of a specific part of your screen, press Control-Shift-4 and drag your cursor over the appropriate area.
