The only way to get Herobrine is via a plugin yes, you don't even need those code elements, just create a new entity handler to handle the AI and use a hashlist to keep track of it, no problem, there are even tonnes about.

What I'm saying is, Herobrine -the ledgend- does not exist, its fake, its a joke by the developers (what we would like to add but cant). People have caught onto this, developed the myth, and then people made the plugins to simulate/implement Herobrine.

infact last MineCon, Notch said it best when asked if HB was returning:
"Herobrine isn't real, thats a dumb question" (and the look on the kids face was priceless, thanks MasterCard)

To be honest, I don't know any of the following things:
Why this thread exists
Why I'm posting
Why I checked for a reply
Pi down to 36 decimal places.

It is a mod! A mob who build... "LIE"
They can get the Zombie code + Human code + Enderman Code "Pieces of it" = Herobrine!

because its always been a joke, and every minecon they get asked, and in every one of them they say "no, herbrine isnt real".

I shut down my motem whent into mcp decompiled and looked through EVERY SINGLE Bit Of Code nothing it was so worth the hour.

any more reasons?

Some say he is a player that gets on your world via internet. No coding for that. BUSTED.

I know he is fake for multiple reasons:

he is stupid
notch doesn't have a dead brother
and, the coding for herobrine is 1: non existent. and 2: pretty hard to make a mob that builds things that it actually builds itself instead of naturally generated things like villages.

He is fake. There shall be no reasons for why he isn't.
