Savoir quelle entity regarde le joueur

[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
{
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);
}

[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)

[Gugu]

Essaie de voir de quelle partie ça viens

[isador]

ca vient du .getEntitiesWithinAABB

[robin4002]

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