Savoir quelle entity regarde le joueur

Gugu

Fais un check que la méthode ne return pas null

isador

comment ca?

Gugu

if(par2World.getEntitiesWithinAABB(CoeMob.Mob.MobtestEntity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D)) != null)

isador

par contre si je veux check avec plusieurs entity comment faire?

edit: j’ai un NPE sur if(par2World.getEntitiesWithinAABB(CoeMob.Mob.MobtestEntity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D)) != null)

Gugu

Essaie de voir de quelle partie ça viens

isador

ca vient du .getEntitiesWithinAABB

Dans ce cas ton objet world est null, envoie toute ta classe.

private World par2World;
Forcement il est null si tu fais ça …
Vire se truc et remplace par2World par player.worldObj

isador

car crash plus mais target est toujours null
