docs: Restoring online skins for offline/cracked players

[unitythemaker]

Hey, we are trying to keep non-cracked users seeing skins. In BungeeCord servers, we used the SkinsRestorer plugin. We want to replace our BungeeCord with Gate, but I could not make the skins work. I tried installing SkinsRestorer on the spigot server but got the below file generated (I have enabled BungeeCord option in spigot.yml):

So, in this case, I can maybe try Gate Lite mode, but from my understanding, this would cause my AuthMe to save all users with the same IP address.

Maybe I understood something improperly, but it would be great if you could help!

Hmm, after joining the Discord server and reading the docs more carefully, I've got more information.
So the Lite mode does not lose the real IP but it does not support server switching. I need another proxy to do that. Maybe I can try to write an extension to achieve this without proxy chaining. I can try to write a Gate extension for SkinsRestorer.

If this is correct and if Gate won't add something like this built-in, I guess we can close that issue.

Hey @unitythemaker we can definitely work this out in an extension and you won’t need SkinsRestorer on spigot. You can change the skin textures in GameProfileRequestEvent https://gate.minekube.com/developers/events.html#available-events. This method applies the skin only once on login to the proxy.

We should prop add docs about it to the dev guide.
