AI is a huge topic if you haven’t done any AI in any language you will find it very difficult. if you dotn have pro you cant have any fancy features like nav meshes which are really good for AI but you can use things such as way-point system look up on YouTube or Google for a way point pathfinding tutorial. but to achieve the mmorpg you may want to look at the angry bots demo the spider bots use sphere colliders to tell when the player is close a outer one activates inner ones and when you trigger the inner one it chases you (probably uses a raycast for rotation to player). that will be a good start and i believe it is in java.
sorry i messed up links this one is 100% free
