Resolves https://github.com/fn2006/PollyMC/issues/150
If the game is launched in offline mode, pass invalid API servers via
the -Dminecraft.api.* system properties. This workaround is mentioned
here:
https://github.com/FabricMC/fabric-loom/issues/915#issuecomment-1609154390
I think this change is appropriate to make here in PollyMC even though
the Fabric developers decided against using it there. If a user wants to
override the API servers back to the vanilla values (in order to use
Auth Me or something), they can do so by setting the following custom
JVM args on the instance:
-Dminecraft.api.env=PROD
-Dminecraft.api.auth.host=https://authserver.mojang.com
-Dminecraft.api.account.host=https://api.mojang.com
-Dminecraft.api.session.host=https://sessionserver.mojang.com
-Dminecraft.api.services.host=https://api.minecraftservices.com
Previously, auth args would override any user-specified args, but this
patch also changes that behavior so user-specified args are now passed
last.
