Savoir quelle entity regarde le joueur
-
Petit up car je comprend pas trop le code de gugu
-
Oui, l’entité Target est la cible.
-
Donc en fait si je veux écrire un nbt dans l’entity visé faudrat utiliser la variable Target ?
EDIT:
problème: target renvoi toujours nullif(kb.keyCode == questKey.keyCode && mc.currentScreen == null && player.getCurrentEquippedItem() != null && player.getCurrentEquippedItem().getItem() == CoeQuestMain.quest)// ADMIN { FMLNetworkHandler.openGui(player, CoeQuestMain.instance, 2, player.worldObj, (int)Math.floor(player.posX), (int)Math.floor(player.posY), (int)Math.floor(player.posZ)); if(par5 && par3Entity instanceof EntityPlayer && !par2World.isRemote) { player = (EntityPlayer)par3Entity; Entity target = null; List entityTagetList = par2World.getEntitiesWithinAABB(Entity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D)); for(int i = 0; i < entityTagetList.size(); i++) { Entity entityTarget = (Entity)entityTagetList.get(i); if(entityTarget != player && entityTarget instanceof EntityLivingBase) { EntityLivingBase entityLivingTarget = (EntityLivingBase)entityTarget; Vec3 vec3 = player.getLook(1.0F).normalize(); Vec3 vec31 = entityLivingTarget.worldObj.getWorldVec3Pool().getVecFromPool(entityLivingTarget.posX - player.posX, entityLivingTarget.boundingBox.minY + (double)(entityLivingTarget.height / 2.0F) - (player.posY + (double)player.getEyeHeight()), entityLivingTarget.posZ - player.posZ); double d0 = vec31.lengthVector(); vec31 = vec31.normalize(); double d1 = vec3.dotProduct(vec31); if(d1 > 1.0D - 0.025D / d0 && player.canEntityBeSeen(entityLivingTarget)) { target = entityLivingTarget; } else { target = null; } } } } } else if(kb.keyCode == questKey.keyCode && mc.currentScreen == null) { FMLNetworkHandler.openGui(player, CoeQuestMain.instance, 1, player.worldObj, (int)Math.floor(player.posX), (int)Math.floor(player.posY), (int)Math.floor(player.posZ)); } System.out.println("target: " + entityTarget); System.out.println(mouseOver); } -
bon pour le problème de null c’était moi, tromper de condition
maintenant ca crash au niveau du .getEntitiesWithinAABB deList entityTagetList = par2World.getEntitiesWithinAABB(CoeMob.Mob.MobtestEntity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D));le crash report:

Fais un check que la méthode ne return pas null
-
comment ca?
-
if(par2World.getEntitiesWithinAABB(CoeMob.Mob.MobtestEntity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D)) != null)
-
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)

Essaie de voir de quelle partie ça viens
-
ca vient du .getEntitiesWithinAABB
-
Dans ce cas ton objet world est null, envoie toute ta classe.

Vire se truc et remplace par2World par player.worldObj -
car crash plus mais target est toujours null
