Résolu Faire un double extends

[Drastic]

Bonjour, pour faire ma “Dynamite”, j’ai besoin d’extends la classe EntityThrowable pour la lancer mais aussi la classe Entity pour la faire exploser. comment faire ?

[Heaven]

ok j ai trouver un bout de code qui devrais te servir

Par hasard, est-ce-que EntityThrowable extends Entity ?
Si c’est le cas, tu as juste à faire un extends EntityThrowable !

[Drastic]

oui mais si je met

private void explode()
            {
                float f = 4.0F;
                this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, f, true);
            }

ca me met une erreur : the method explode is undefined for the type “maclasse”

Ton

private void explode()
{
    float f = 4.0F;
    this.worldObj.createExplosion(this, this.posX, this.posY, this.posZ, f, true);
}

est mal placé (déjà dans une méthode de ta classe).
Il n’y a pas une méthode qui fait la même chose et que tu pourrais appeler à la place ?

[Heaven]

tu pourrais peut être regarder dans la classe de la Tnt ?

[Drastic]

alors en fait g mis le explode alors que pas besoin. par contre, comment régler la taille de l’explosion ?

[Heaven]

et bien il faut voir dans la classe de la Tnt
je ne suis pas sur mais cette méthode peut etre utile

 public void onBlockDestroyedByExplosion(World p_149723_1_, int p_149723_2_, int p_149723_3_, int p_149723_4_, Explosion p_149723_5_)
    {
        if (!p_149723_1_.isRemote)
        {
            EntityTNTPrimed entitytntprimed = new EntityTNTPrimed(p_149723_1_, (double)((float)p_149723_2_ + 0.5F), (double)((float)p_149723_3_ + 0.5F), (double)((float)p_149723_4_ + 0.5F), p_149723_5_.getExplosivePlacedBy());
            entitytntprimed.fuse = p_149723_1_.rand.nextInt(entitytntprimed.fuse / 4) + entitytntprimed.fuse / 8;
            p_149723_1_.spawnEntityInWorld(entitytntprimed);
        }
    }

[Drastic]

oui mais je netrouve pas

[Heaven]

je viens de te donner la soluce (peut etre)

[Drastic]

@Heaven malheureusement la soluce n’y est pas
