Résolu Créer un bateau

[Eryah]

Bonjour, je me présente, Eryah. Je risque de me manger quelques points de réputation en moins avec se topic. 
Bien, dans mon mod, j’aimerai inculure quelques bateaux.

• Bateau motorisé
• Bateau en fer
• Bateau en fer motorisé
• Bateau thermorésistant
• bateau thermorésistant motorisé

Donc, j’aimerai avoir plusieurs renseignement ( J’ai bien fait des recherche !! Mais j’ai rien trouvé en 1.8, même 1.7, et ce n’était pas très clair pour moi)

• Comment augmenter/réduire la vitesse du bateau
• Comment empécher le bateau de casser en rencontrant un bord
• Comment rendre un bateau résistant à la lave
• COMMENT REGISTER UN MOB ( Avec et sans œuf, j’ai le même problème avec ma poule au œuf d’or, je n’arrive pas à la register

Je vois bien que la vitesse se régle ici

Mais j’ai peur de faire du caca, donc comment bien régler la vitesse ( Je veut pas un jetski ! )

[Laserflip33]

Salut,
Déjà es-tu arrivé à faire un bateau custom simple?

[Eryah]

Non, vu que je ne sais pas comment register les entités, j’ai essayer plusieurs tutos, rien ne fonctionne

[Diangle]

Tu as des tuto pour créer des entitées. Ensuite, pour se qui est des bateaux, créer un item avec des metadata et en fonctions du craft tu fait spawn le bateau avec les propriétés que tu veux.

[Eryah]

J’ai essayer le tuto sur les entités de MFF en premier biensur, mais il ne fonctionne pas.
J’ai peut-etre fait un erreur sur les classe
Laisse moi allez chercher un truc a boire, je refait la ligne , et je te la passe

[Eryah]

Alors , mettez moi un petit -1 plz, si mon register de mon chikheineuh ne fonctionnait pas, c’est simplement que la classe Render n’existait pas
Enfaite si, elle existait, mais mettez moi alors un -2

Donc vila, j’ai refait les codes du register

[SCAREX]

Problème résolu ?

[Eryah]

Le sujet du topic parle des bateaux que je voudrais créer, et non pas du register de mon poulet
Mais sinon, toujours pas

[SCAREX]

Où est le problème actuellement ? Tu n’arrives pas à l’enregistrer ? Ton model ne s’affiche pas ? Tu as un crash report ?

[Eryah]

Actuellement, j’essaie de regler le problème de register de mon chicken.
Sur son constructeur

​public RenderGoldenEggChicken(ModelChicken model, float shadow)
{
super(renderManager, model, shadow);
}

Je n’arrive pas a vouloir faire afficher sans problème le code que je veut, qui est le même code que dans le tuto

1. public RenderMobTutoriel(ModelBiped model, float shadow)
2. {
3. super(model, shadow);
4. }

Mais je ne comprend pas, Eclipse veut toujours rajouter renderManager…

---

EDIT

---

Je viens de bidouiller plein de null, et il  n’y a plus d’erreur, j’espère que cela va fonctionner…

[SCAREX]

la classe c’est RenderManager, regarde que tu n’ai pas enregistré une classe du même nom dans tes imports : supprimer la ligne temporairement et fait Ctrl + shift + O puis remets ta ligne et refait Ctrl + shift + O.

[Eryah]

Tout fonctionne ( Pour le poulet ) l’oeuf est la et…
OOOH quelle surprise !
Un crash !

Comment est enregistré ton entité ?

[robin4002]

Pour l’enregistrement des entités, il parait que seul registerModEntity est nécessaire.
registerGlobalEntityID ne devrait pas être utilisé car il pose des problèmes de limitation (256 entité au total, y comprit ceux de Minecraft).
Alors que registerModEntity est limité à la taille l’int, et est interne à chaque mod.

J’ai vu Lex dire ça, après je n’ai jamais tester.

Pour tout ce qui concerne les bateaux, étudie le code du bateau de Minecraft, il y a de forte chance que tu y trouve ta réponse.
(juste pour information, la façon dont Minecraft gère les collisions va faire que le joueur va prendre feu lorsqu’il sera dans ton bateau qui résiste à la lave, donc il faudra lui ajouter l’effet de résistance au feu).

[Eryah]

J’ai bien retirer donc la fonction registerGlobalEntityID, mais…

• L’œuf disparait ( Wow… quelle surprise… )
• Le nom de mes entités ne sont plus ‘goldenEggChicken’ et ‘motorizedBoat’, mais ‘ut.goldenEggChicken’
• Je crash toujours

C’est le m^me crash report, inutile de vous le redonner

---

Register des mes entity

Main Class

EntityRegistry.registerModEntity(GoldenEggChicken.class, "goldenEggChicken", 420, this.instance, 40, 1, true);

EntityRegistry.registerModEntity(MotorizedBoat.class, "motorizedBoat", 420, this.instance, 40, 1, true);​

ClientProxy

​RenderingRegistry.registerEntityRenderingHandler(GoldenEggChicken.class, new RenderGoldenEggChicken(null, null, 0));

RenderingRegistry.registerEntityRenderingHandler(MotorizedBoat.class, new RenderBoat(null));

L’erreur vient de la, je m’en suis rendu compte en copier collant le code…
Mais que faut-il mettre dans ‘null’

[SCAREX]

çà dépend de tes classes.

[robin4002]

u_U
Si tu enregistre des rendus avec un modèle null, faut pas s’étonner d’avoir des NPE …

Il n’est pas possible de coder correctement sans apprendre le Java.

Déso de l’absence… Quelques problèmes… Enfin voila

Le but est donc de savoir il faut mettre quoi à la place des ‘null’ ici

​RenderingRegistry.registerEntityRenderingHandler(GoldenEggChicken.class, new RenderGoldenEggChicken(null, null, 0));

RenderingRegistry.registerEntityRenderingHandler(MotorizedBoat.class, new RenderMotoBoat(null, null, 0));
