[1.16] Using NetworkManager.createAddEntityPacket causes NoClassDefFoundError on dedicated server
itsmeow opened this issue ยท 6 comments
Making a non-living entity and overriding getAddEntityPacket to return NetworkManager.createAddEntityPacket(this); causes a crash when this entity is spawned on a dedicated server.
I've looked into said code and I am a bit confused considering ClientLevel (class_638) isn't referenced, but maybe it could be blamed on this line containing a client referenece without @Environment. It seems to take place within NetworkManager, so that's confusing. It's not something in my source either, no client references in EntityModEgg.
I tested it with another projectile using a different parent class, the issue remains.

Can confirm for 1.18, though only on Fabric servers. Forge seems to work as expected.
Appears to be fixed, although my entity doesn't render... Probably something on my side, but could be packet issue.
Can verify client is not adding/receiving entity, as shown by lack of hitbox appearing.
