Solved Disguises.

Currently, LibsDisguises makes you invisible, and puts a zombie in your place that teleports to you as you move (basically), Is there any way that I can make it so that they see me as a Zombie but I don't end up being inside the zombie, which makes it hard to pvp.

Send a destroy packet for the Zombie. Or intercept the spawn one.

You could also disguise you as the mob, by sending a destroy packet with your EntityID to all clients and then a spawn one for a zombie with the same entity id. Worked some time ago. Problem here is, that for players newly entering the area, the original packet is send, so you must intercept it.

Maybe it has changed in the last versions though, I tried that around 1.7.

And there are probably better ways for this, but I don't know any.

 

I decided to go with iDisguses instead, much easier to use and I don't have to go through the hassle of destroying the mob each time, which seemed to be kinda laggy for some reason.
