Problème arc custom
-
Salut,
J’ai créer un arc custom avec une flèche custom. J’ai recopié les codes de l’arc de base et de la flèche de base. Tout marchait bien, sauf que j’avais un problème avec ma flèche, elle ne se positionnait pas correctement, au bout de 2 secondes par exemple, elle se déplaçait de 3 blocs. J’ai résolu ce problème mais maintenant, quand je suis en survival, ma flèche me tape directement. La classe de l’arc est la classe de base, voici celle de la flèche:

Personnellement je te conseille de faire un copier-coller de la classe de la flèche plutôt de mettre ta classe extends EntityArrow car le code de Minecraft est toujours fait n’importe comment
PS : pense à l’utilisation des balises java au lieu des balises code pour la coloration syntaxique
-
Ha oui j’avais oublié ^^
Si je copie colle EntityArrow ça marche partiellement. Les flèches se positionnent mal, si je tire sur un mur, elle reste 2 blocs plus loin. Le seul problème que j’ai c’est vraiment pour les dégâts que je subis…
-
C’est bizarre parce que normalement avec un pure copier-coller ça devrait avoir le même fonctionnement, sinon c’est que tu as modifié quelque chose
-
Je suis pas fou ^^ la fréquence d’update était sur 20 quand j’ai register l’entité, la classe était exactement la même excepté le nom mais ça ne marchait pas bien…
-
Perso, moi j’ai fait un arc custom qui lance les flèches de Minecraft et j’ai aussi des problèmes de position, la flèche part de travers sur le client puis est repositionné 1ou2 secondes après.

pareil que toi j’ai fait un arc (copié-collé de la casse principale) et avec une fleche custom(pareil copié collé de la classe principale ) et sa fait ce problème
-
Je suis allez regarder les sources du Balkon’s weapon mod.
J’ai regarder la classe EntityProjectile et la classe EntityCrossbowBolt et tout marche niquel. -
Essaie d’implémenter l’interface IEntityAdditionalSpawnData pour mieux synchroniser
-
Je n’essaye pas parce que j’ai déjà mis beaucoup de temps pour le faire et vu que ça marche comme ça je ne change plus. Maintenant je dois juste faire une hitbox plus réaliste, en longueur. Je suis en train de chercher, je tiens au courant pour les intéressés !
