Hey guys, I was wondering around youtube for tutorials on how to make a new boss, I mean, I already know how it is going to look, speed, health and all that stuff, I know how to make the textures in youtube, and all of that, but I downloaded the mod loader, mcp, java and eclipse, but I don't know how to "code" a new boss in minecraft. I don't want this boss to just appear anywhere, I want to put it there myself, but for that he couldn't despawn, or something... Well, what I need from you guys are tutorials you made or you found somewhere. If you found any tutorials tell me please Thanks for attention
