I'm trying to create a plugin that spawns a human entity (using PacketWrapper 1.7.10 - PacketPlayServerNamedEntitySpawn) to create an npc. Then, I listen for interactions with said npc by registering a packetadapater. All works, but here's the catch: It doesn't work on servers that use spigot 1.7.x but allow 1.8 clients to join. I searched around a bit and came to a forum, where someone told someone that he needed to use PacketPlayOutPlayerInfo and send it to everyone, or else 1.8 clients wont render the entity. So basically what I'm asking you guys is: How would I go about creating such a Packet and then sending it to everyone, so this plugin works even on 1.7 - 1.8 servers. Thank you.
