Invisible Entities?

Hey Guys,
I was looking for a possibility to create invisible Enitites(For e.g. Zombies or Skelletons)

Player have an API for this but Zombies etc..

Is this possible to add invisible Zombies?

Like VanishNoPacket does, just for certain Mobs.

greets

 

Why would you ever want them to be invisible?

 

Actually i want to create a Minecraft Instance Plugin

 

Can't you add invisibility potion to them? (or is that a later update?)

 

That would be possible in next updates, but some ppl still need to see the Mobs. Like a Instance in a MMO

 

you might want to put in a feature request with bukkit if you cant find another way to do it. Another option would be to try to contact the vanishnopacket maker and see how he did it.
