Let's see if we can reword the error for you to understand...

Fatal error: Class Windows missing 3 functions which must be implemented. getNetworkType() getName() getDefaultSize() in /storage/emulated/0/PocketMine-MP/plugins/SW09/src/skywars/Windows/Windows.php

 

Can you give me example please?

 

Just implement these methods like you did with the other ones.

 

Ok
