EntityProjectile
-
Bonsoir,
J'ai créer une entity projectile pour une arme dans mon mod.
Je rencontre deux problèmes:
-1) J'arrive pas a augmenté la vitesse du projectile.
-2) Le projectile décent progressivement une fois tiré (comme la flèche), je voudrais qu'il reste droit comme les fireball.
Je vous donne la classe de mon entity:

Salut,
Pour résoudre tes deux problèmes il faudrait override la fonction onUpdate.
-
Salut,
Quand j'override la fonction onUpdate sans rien ajouter forcément ça change rien.
J'ai donc pris les codes de la fireball.
J'ai réussis a augmenté la vitesse de mon entity mais elle tombe toujours comme les flèches, je cherches a faire une entity avec un trajectoire toute droite et pas en "courbe".
Je te passe ma classe:

Retires cette ligne :
this.motionY *= (double)(this.rand.nextFloat() * 0.2F);et celle-ci :
this.motionY += this.accelerationY;
