Eigene NPCs in der 1.8 erstellen! [UPDATE: NPCInteractEvent]

[xMeWinatorx]

@naturboy

Echt? Noch ein Grund dafür die 1.8 zu hassen! Hat jemand ein Workaround dafür? Also das man das Bett vor faked oder so?
Wie genau muss das mit dem Bett denn sein? Muss das Bett dann an der BlockPosition liegen?

Gerade eben ausprobiert das Bett lässt sich per Blockchange auch auf einer anderen y höhe positionieren also nur x und z cordinate müssen übereinstimmen.

Hey ,
hat jemand von euch zufällig eine auf Packets basierende walk() Methode für die 1.8 ?
Komme mit dem "PacketPlayOutRelEntityMove" nicht wirklich klar. :/

Danke im Vorraus!

Mit dem Packet kannst du deine Entity nur 4 Blöcke bewegen, danach greift das Packet nicht mehr, und du musst die Entity teleportieren. Wenn du also einen relativ gut aussehenden Movement haben willst, musst du die Strecke so splitten, dass sie immer auf 4 Blöcken besteht!

#EDIT: Was mir noch einfallen würde, wäre ein Tier die KI zu nehmen, und dann den NPC auf das Tier zu setzen, und das Tier durch die Navigation oder Pathfinder zu deiner gewünschten Locations schicken. Am Ziel dann einfach das Tier wieder löschen.

Mit diesem Update folgt nun ein sehr viel gefragtes PlayerInteractNPCEvent. Dieses Event wird mit Netty arbeiten, und erfordert Implementierungen in euer Plugin. Euch ist es freigestellt, dieses Event zu benutzen. Wollt ihr es jedoch benutzen, so müssen die Methoden NPC#injectNetty(Player) im PlayeRJoinEvent und die Methode NPC#ejectNetty(Player) im PlayerQuitEvent aufgerufen werden. Weiterhin gilt, NPCs müssen asynchron gespawned werden!
