Merci, ça fonctionne parfaitement
Maintenant j’ai un problèmes x) Comment je rajoute un model à l’entitée qui est lancé ? (Model déjà exporté)

robin4002

Comme pour n’importe quelle entité. Il faut faire un render.

QuantumSheep

Oui je sais mais tu n’aurais pas un tuto, je suis vraient débutant dans le milieu x)

C’est le même principe, sauf qu’au lieu d’utiliser RenderBiped il faut utiliser directement Render. Tu peux aussi t’inspirer des autres rendus de Minecraft.

QuantumSheep

J’ai pris un peut du tuto et la class RenderArrow de minecraft en la modifiant et il me reste un problème au niveau du ClientProxy, Je met cette ligne dans le ClientProxy :

RenderingRegistry.registerEntityRenderingHandler(EntitySpear.class, new RenderSpear(new ModelBase(), 0.5F));

et il ne l’accepte pas au niveau du ModelBase.

Pourquoi ModelBase ? Ton modèle s’appelle ModelSpear. Et le code de rendu n’est pas bon pour ce que tu veux faire, le rendu de la flèche rend directement la flèche et non un modèle.

QuantumSheep

J’ai remplacer comme ça : ```java
RenderingRegistry.registerEntityRenderingHandler(EntitySpear.class, new RenderSpear(ModelSpear(), 0.5F));


Et ça ne fonctionne pas, il me met une erreur sur ModelSpear.

Tu n'aurais pas un code qui me montrerais comment faire ? :'(

robin4002

Un exemple de rendu :
https://github.com/FFMT/nanotech_mod/blob/master/common/fr/mcnanotech/kevin_68/nanotechmod/main/client/renderer/RenderSatelite.java
Le modèle ne passe pas par le constructeur, donc c’est enregistré directement comme ça :
https://github.com/FFMT/nanotech_mod/blob/master/common/fr/mcnanotech/kevin_68/nanotechmod/main/core/ClientProxy.java#L81

QuantumSheep

Ok, c’est bon, le model se génère bien, seul problème c’est que la lance est décalée et quand je la lance elle se tp plus en hauteur…

SCAREX

Après il faut changer comment est rendu ton model avec des translations et des rotations. Il faut juste vérifier que le problème ne soit qu’au rendu et pas au niveau de la hitbox, fait F3+B pour voir les hitbox.

QuantumSheep

C’est la même Hitbox qu’une flèche c’est bizarre que ça ne fonctionne pas… Voilà mon model Techne en pièce jointe (Modèle provisoire).

QuantumSheep

Personne n’a de solution à ce décalage ? :'(___Ah et nouveau problème (Triple poste oklm), Quand j’utilise n’importe quel autre item que je créer (Même sans méthodes juste un item normal) il envois l’entitée de la lance et se charge O_o

robin4002

Envoies nous ton code. Et pour le décalage il suffit de faire un petit GL11.glTranslate dans le code du rendu.

QuantumSheep

Voilà le github avec les derniers codes : https://github.com/ArkCraft/ArkCraft/tree/master/src/main
ça sera surement plus pratique

robin4002

Il n’y a qu’un item sur le github.

QuantumSheep

Oui, je viens de changer : https://github.com/ArkCraft/ArkCraftMod/

SCAREX

Fais un peu d’ordre dans ton code, y’a pas besoin de 40 glScale à la suite.

Dans ton glTranslate, rajoute un -1 sur l’axe y, il faut changer ces valeurs pour avoir la bonne.

QuantumSheep

C’est le render originel de la flèche
Comment je change pour -1, je n’ai aucunes connaissances en GL
