Hello guys, recently, I tried to use the nms with spigot, because I don't understand how it works... I know how to use reflection but I don't understand the Pathfinder goals, in particular on the passive mobs. I want to make passive mobs attack the players with custom strength, and others parameters like speedattack... I would like to make mobs attack with spells like fireball, particles, ... and make items attack, like a enraged apple... Yes, an enraged apple ... I also want to learn how to modify items particularity, like durability, damage, speed when the item is held, but I know that it isn't nms but that it is NBT tags. Thank you for your help ThePenspinneur NB: If you have an API or a library for this, in spigot 1.8.3, you can give me a link, or the file on the replies, it would be my pleasure .
