Lastnight i started playing playing around with mob brains, goal was to make a mobs more interactive with the client.
Heres one of the brains i made - Only a silly/simple brain, but i think some players would like.
Simple Mob, thats turns the npc to a client if they entre the npcs aggro range, the brain will automatically Emote(Military) the player for the amount of time the npc is facing the player, then the npc will turn back to its normal heading.
To stop the npc from going mad, i have set a 15sec time to the npc, some once it has emoted the player, it will leave the player along for the remain amount of time left.
Also with the NPC, i have played with the mobs models and added 10 different random models that the npc can load up from, just so you dont always have all the same boring modela all over the place lol.
I know its a bit of a silly post, but someone out there might enjoy it, or it might lead to greater things, Enjoy
