Je pense que si tout ce qui touche le rendu du joueur est dans ton RenderCustomPlayer ça ne servirai a rien mais que si c'est dans une autre classe alors la oui ç'est nécessaire. Après je ne suis pas expert au niveau des rendu donc je dis peut être des bêtises.

Pour empêcher ça mets les positions x,y et z de l'event, comme ça:

playerRenderer.doRender(event.entityLiving, event.x, event.y, event.z, 0, event.partialRenderTick);

@'AymericRed':

Non il y a un endroit où mc appelle une fonction qui n'appartient que au ModelPlayer, donc il faut que ton modèle soit extends ModelPlayer.

Effectivement ça ne crash plus et le modèle s'affiche, merci.

@'Plaigon':

Lors de tes essaies, RenderPlayerAPI est-il installé ? Peut-être qu'il patche certaines classes de MC dans le but de forcer ce cast qui cause ton exception. Essaie sans cet API, y'a pas de raisons apparentes pour qu'entre la 1.7x et la 1.8, le code ne marche plus.
Sinon si tu n'en viens pas à bout, essaie d'extends ton modèle par ModelPlayer et de virer les shapes du ModelPlayer qui ne t'intéressent pas.
Si finalement après tout ceci, tu n'y arrives pas, je te propose la solution C, d'utiliser RenderPlayerAPI qui est plutôt facile d'utilisation, surtout qu'il y a un tuto sur le post officiel et que des mods open source s'en servant pour remplacer le modèle du joueur existe. Peut-être qu'une (très)ancienne version du Aether mod s'en servait. A toi de rechercher

Merci pour l'aide apportée et oui maintenant plus qu'à enlever ce que je n'aime pas.

Je passe en résolu.

Bonjour,

Donc j'ai créer un nouveau modèle pour le joueur et on m'a dit d'utiliser "ObfuscationReflectionHelper.setPrivateValue" dans le RenderPlayerEvent.Pre . Du coup pour tester j'ai essayer de remplacer le model  du joueur par celui du cochon, ça n'a pas fonctionner, j'ai essayer avec un autre model que j'avais ajouter, pareil.

Voici comme j'utilise l'event :

@SubscribeEvent
public void onRenderPlayerEventPre(RenderPlayerEvent.Pre event)
{
ObfuscationReflectionHelper.setPrivateValue(net.minecraft.client.renderer.entity.RendererLivingEntity.class, event.renderer, new ModelPig(), new String[] { "mainModel", "field_77045_g" });
}

Le crash log:

Mais ce que je ne comprend pas, c'est que ce code marche en 1.7.10 ,au niveau du mapping j'ai regardé et le field de ma version est le même. Ce bug serait causé par le fait qu'il faut en 1.8 que le modèle de remplacement pour le joueur soit un modèle qui utilise le ModelBiped ?

Bonjour, alors déjà désolé de m’éterniser sur ce sujet mais comme je l'ai dis je ne suis pas dispo pendant la semaine ^^. Donc pour mon problème c'est à peu près régler : Quand je meurs les données sont sauvegardés et charger mais le problème c'est que ces données ne sont presque qu’envoyé au serveur et très peu de fois des deux côtés. Mon problème vient de ma méthode pour sync ? ou lors de l'envoie des données au respawn ?

Comment ça ? Tu veux que je regarde si dans le onMessage j'envoie les données vers le serveur et le client ?

Voila le code de mon event handler :

Alors quand je rejoins le monde le message que j'ai mis dans le loadNBTData apparaît bien dans la console et quand je meurt celui du saveNBTData aussi. Les fonction sont donc bien appelées mais alors pourquoi alors je n'obtiens pas la valeur de mon argent ?

Oui ça marche maintenant je peux relancer mon monde en solo et en multi sans crash. Mais quand je meurs je perd mes données. Je sauvegarde mal les données dans LivingDeathEvent ?

Donc si j'ai bien compris pour envoyer le paquet il ne faut pas que je passe par EntityJoinWorldEvent mais par autre chose dans l'event handler ?
