I'm completely new to datawatchers. I read a tiny article about datawatchers so now I know I can add an object to a certain id to make it do stuff. That I don't even know. I heard you can use datawatchers to make an EntityCreeper expand and by turn explode and some other cool things. Is there a javadoc/tutorial/document I can view to know all about datawatchers or at least get a grasp. I want to know what you must do to make an EntityCreeper expand and anything else and what methods/functions would do what. Thank you very much! As well, I'd like to know how to make an EntityLiving not disappear when too far away. I've been using EntityLivings for disguising players, but now I can not seem to figure out why they would disappear after being too far away.
