J’ai régler le soucis du probleme en le supprimant car je n’en ai pas besoin puisque pour moi la sarbacane ne dois pas faire de dégats donc tout mars , les flechettes sont récupérer , sont décompter sont tirer , mais pas de rendu de la flechette /: A terre elle est invisible et l’effet slowness ne se fait pas non plus /:

J’ai également un crash report quand mon item flechette touche un mob ! :

Le crash est causé par ça :

DamageSource damagesource = null;

if (this.isBurning() && !(movingobjectposition.entityHit instanceof EntityEnderman))
{
movingobjectposition.entityHit.setFire(5);
}

if (movingobjectposition.entityHit.attackEntityFrom(damagesource, (float)k))

damagesource est null. Il faudrait plutôt mettre :
DamageSource damagesource = shootingEntity != null ? (new EntityDamageSourceIndirect(“arrow”, this, this.shootingEntity)).setProjectile() : (new EntityDamageSourceIndirect(“arrow”, this, this)).setProjectile();

Pour le rendu c’est pas du tout ça, c’est une nouvelle classe qu’il faut créé, ça fonctionne comme le rendu d’un mob.

[Flow]

J’ai changer par ce que tu m’as dit donc ceci : ```
DamageSource damagesource = shootingEntity != null ? (new EntityDamageSourceIndirect(“arrow”, this, this.shootingEntity)).setProjectile() : (new EntityDamageSourceIndirect(“arrow”, this, this)).setProjectile();

[edit] = Ca marche !! :D Mais sa cause des dégats , et j'aimerais que sa n'en cause aucun ainsi l'effet slowness ne marche pas des idées ?

Dans ce cas, toute cette partie :

if (this.isBurning() && !(movingobjectposition.entityHit instanceof EntityEnderman))

{
EnchantmentHelper.func_151384_a(entitylivingbase, this.shootingEntity);
EnchantmentHelper.func_151385_b((EntityLivingBase)this.shootingEntity, entitylivingbase);

{

}
}

this.playSound("random.bowhit", 1.0F, 1.2F / (this.rand.nextFloat() * 0.2F + 0.9F));

if (!(movingobjectposition.entityHit instanceof EntityEnderman))
{
this.setDead();
}
}
else
{
this.motionX *= -0.10000000149011612D;
this.motionY *= -0.10000000149011612D;
this.motionZ *= -0.10000000149011612D;
this.rotationYaw += 180.0F;
this.prevRotationYaw += 180.0F;

}

Remplace par :

if(movingobjectposition.entityHit instanceof EntityLivingBase)
{
((EntityLivingBase) movingobjectposition.entityHit).addPotionEffect(new PotionEffect(Potion.moveSlowdown.id, 20, 1200));
}

[Flow]

Ca marche pour les deux mais les mobs marchent toujours mais plus lentement y a t il un moyen qu’il ne bouge plus radicalement ?

[robin4002]

movingobjectposition.entityHit.noClip = true;
Le problème avec ça, c’est qu’il bougera plus définitivement, il faudrait remettre noClip sur false au bon d’un certains temps.

[Flow]

par exemple le temps normal d’une potion de slowness c’est possible genre 1:07 ? Et ou le rajouter ?

[Überfap]

Changes la durée et la puissance du PotionEffect

[Flow]

(Potion.moveSlowdown.id, 20, 1200)); 20 = en ticks ou en secondes ?

J’ai riens dis

J'ai aussi quand je change la durée de la potion effect ca ne change rien :/

Et l'orsque on tire avec la Sarbacane dans l'inventaire sa nous met Slowness "0:9" mais l'effet ne s'applique pas a nous je ne sais pas pourquoi le cadre slowness apparait dans l'inventaire..

[robin4002]

Si tu enlève :
float f11 = (float)par1EntityFlechette.arrowShake - par9;

if (f11 > 0.0F)
{
float f12 = -MathHelper.sin(f11 * 3.0F) * f11;
GL11.glRotatef(f12, 0.0F, 0.0F, 1.0F);
}
ça crash toujours ?

Aussi, enlève la ligne :
private static final String __OBFID = “CL_00000978”;
Sinon tu vas avoir des problèmes lors de la compilation.

Pour les deux autres problèmes, je ne sais pas.

[Flow]

Oui ca crash toujours malheureusement

Bizarre qu’on tombe sur un npe et pas une boucle infini.
Remplace :
protected ResourceLocation getEntityTexture(EntityFlechette par1EntityFlechette)
{
return this.getEntityTexture(par1EntityFlechette);
}
par :
protected ResourceLocation getEntityTexture(EntityFlechette par1EntityFlechette)
{

}

Toujours le même crash je vais te passer tous mes codes je pense que tu pourra t’y retrouver plus facilement et cibler plus facilement également le problème !
