Je dois donc créer une nouvelle entitée je peut donc en créer une nouvelle et recopier celui de Arrow ( pour l’instant ) et changer en EntityFlechette alors ?

[isador]

oui .

[Überfap]

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.projectile.EntityThrowable;
import net.minecraft.potion.Potion;
import net.minecraft.potion.PotionEffect;
import net.minecraft.util.MovingObjectPosition;
import net.minecraft.world.World;

public class EntitySlowingArrow extends EntityThrowable
{
public EntitySlowingArrow(World world)
{
super(world);
}

protected void onImpact(MovingObjectPosition mop)
{
Entity e = mop.entityHit;
if (e != null && e instanceof EntityLivingBase)
{
((EntityLivingBase) e).addPotionEffect(new PotionEffect(Potion.moveSlowdown.id, 20, 1200));
}
}
}

Voila le code de l’entité qui ralentit, à toi de faire le rendu

[Flow]

J’ai ajoute le code que tu m’as donné et recopier celui de la classe Arrow mais j’ai un probleme avec ceci , je ne sais pas par quoi remplacer :

if (this.shootingEntity == null)
{
damagesource = DamageSource.causeEntityFlechetteDamage(this, this);
}
else
{
damagesource = DamageSource.causeEntityFlechetteDamage(this, this.shootingEntity);
}

C’est le EntityFlechette qui pose problème…Je ne sais pas quoi y mettre, il y avais Arrow avant mais ca ne marche pas non plus…

EDIT : l’effect slowness ne s’applique pas non plus , faut-il changer quelque chose genre nom de classe à remplacé ?

[Flow]

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 :

{

{

}
}

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;

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 !
