I'd like to let a fake NPC sneak but I can't get it that way with the packet maybe someone can give me an example? [1.13]
Does this help you out at all? https://stackoverflow.com/questions/43972766/entitymetadata-packet-issue
I don’t know, does it? You should try it out first before asking if it works. (I don’t mean to sound rude, but that’s what developer do- they develop stuff and try things out).
Nope it does not work too, this is a PacketPlayIn "Packet" he then tells me that the package has not been registered.
