Hello guys!
It was like 3-4 years ago. People were asking for uploading schematics to use them with world edit, but there was no way to upload a file to aternos. People asked in the forums and they only answer was "no plans on it for now".
Well, I have two ideas!
There are some solutions to this problem.
First,
you guys can make a plugin which can download a schematic file with the link given to it. Then it will just put that file in world edit's schematics folder.
Second,
of course I had a look on many pages on spigot and aternos and this is what I just found:
This plugin can upload or download worldedit schematics directly through discord. It depends on Discord SRV which is a known plugin and it's already available on aternos.
This plugin wasn't popular enough so I couldn't submit it in mod/plugin suggesting page.
Hope you guys make this possible. Have a nice time and I'll be happy if you reply with an answer
