Savoir quelle entity regarde le joueur

Überfap

Je n’ai vraiment pas le temps en ce moment, je finirais ça demain mais j’ai des pistes à te donner:

Le Vec3 du player
Le world.getEntitiesWithinBoundingBox()

Essaie de trouver quelque chose avec ça et bonne nuit

isador

merci je vais chercher

Überfap

Alors t’as trouvé ?

isador

non car je vient de me reveiller et je me suis coucher après toi ^^

Gugu

https://github.com/Gugu42/RatchetAndClankMod/blob/master/java/com/gugu42/rcmod/items/ItemDevastator.java

Dans le onUpdate, y’a une fonction qui fait exactement ça;

isador

merci je regarde ca
si je copie colle ca code:


if (par5 && par3Entity instanceof EntityPlayer && !par2World.isRemote) {
if (par3Entity.getEntityData().getBoolean("devastatorFired")) {
EntityPlayer 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;
}

}
}

je peut faire après un


if(target == entityTarget)
{
//mon code
}

?

Gugu

Bah, target = l’entité visée.
Après, tu en fais ce que tu veux.

isador

dans tout les cas target sera egal a entityLivingTarget non?

Gugu

Oui

robin4002

J’aime bien ton message + ta signature.
ça fait
Oui ! Non !
On peut limite compléter avec : en fait je ne sais pas. xD

(Ceci était un message inutile de robin4002)

isador

merci de ta participation robin

du coup gugu avec ton code on peut récup l’entité visé?

isador

Petit up car je comprend pas trop le code de gugu

Gugu

Oui, l’entité Target est la cible.

isador

Donc en fait si je veux écrire un nbt dans l’entity visé faudrat utiliser la variable Target ?

EDIT:
problème: target renvoi toujours null


if(kb.keyCode == questKey.keyCode && mc.currentScreen == null && player.getCurrentEquippedItem() != null && player.getCurrentEquippedItem().getItem() == CoeQuestMain.quest)// ADMIN

else

}
}
}
}

else if(kb.keyCode == questKey.keyCode && mc.currentScreen == null)

}
System.out.println("target: " + entityTarget);
System.out.println(mouseOver);
}

isador

bon pour le problème de null c’était moi, tromper de condition
maintenant ca crash au niveau du .getEntitiesWithinAABB de


List entityTagetList = par2World.getEntitiesWithinAABB(CoeMob.Mob.MobtestEntity.class, player.boundingBox.expand(32.0D, 32.0D, 32.0D));

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)

Essaie de voir de quelle partie ça viens
