Résolu Forge 1.12.2 - Crash serveur avec les paquets

[Vort3x_]

Bonjour/Bonsoir,

Encore une fois cette semaine je me retrouve face à une impasse.
Dans mon précédant sujet “Forge 1.12.2 - Erreur avec gradle | Forge-2860”, je précisais que j’avais changer de machine j’avais donc décider de réinstaller Forge, en bref ce problème fût résolu.
Désormais j’ai remis les SRC de mon mod hors, j’ai un crash serveur (Ce crash proviens au démarrage du serveur.) que je n’avais pas avant, alors je ne sais vraiment pas pourquoi celui-ci est là je me doute bien qu’il n’est pas arriver par magie mais le crash-report est assez incompréhensible :

Dans ma classe praincipale, je charge le paquet comme suit :

}

Ce que je ne comprend pas c’est que j’ai toujours utiliser la même méthode pour mes paquets et jamais il n’y a eu d’erreurs auparavant. D’habitude j’utilise seulement le “SideOnly” mais ici comme j’ai essayer avec “FLMCommonHandler” de m’assurer qu’on était sur le coté client.

Je suis sûr que cette erreur est toute bête mais je ne vois pas comment la corriger, en bref encore un énorme merci pour vos futur réponses !!

[Vort3x_]

Bonjour @robin4002,

Tout d’abord je tiens à m’excuser pour cette réponse tardive.

Ensuite, après avoir fait quelques tests, j’ai trouver la cause de ce crash j’ai récemment ajouter un “core-mod” dans mon mod pour pouvoir transformer la Classe Minecraft afin de changer la limitation de FPS dans le menu (30) hors j’avais mit en parametre de ce core-mod une exclusion

IFMLLoadingPlugin.TransformerExclusions({ "com.mod" }) ce qui corrige le crash serveur !
Je n’y avais pas penser plus-tôt et je me sent légèrement stupide.

En bref vraiment désolé de t’avoir fait perdre du temps mais peut-être que cela servira à quelqu’un.

[robin4002]

Bonsoir,

Le SideOnly(Side.CLIENT) sur la fonction onMessage est la bonne solution, vérifies tes autres paquets car à mon avis ce n’est pas lui le problème.

[Vort3x_]

Bonsoir @robin4002, je ne l’ai pas préciser mais quand je “supprime” la partie :

final BlockPos pos = new BlockPos(message.tileX, message.tileY, message.tileZ);
final World world = Minecraft.getMinecraft().world;
final IBlockState state = world.getBlockState(pos);
if (state !=null) {
        TileEntity tileentity = world.getTileEntity(pos);
	if (tileentity instanceof TileEntityDecals) {
		final TileEntityDecals te = (TileEntityDecals)tileentity;
		te.type = message.type;
	        te.path = message.path;
		te.width = message.width;
		te.height = message.height;
		te.rotation = message.rotation;
		te.writeToNBT(new NBTTagCompound());
	}
}

Le crash ne se produit plus et le serveur remarche, de plus le crash-report pointe bien vers cette la classe qui contient ce Handler.

C’est assez étrange . . .

[robin4002]

Effectivement c’est curieux.
Essaies de mettre le code en question dans une autre fonction dans une autre classe puis de faire appeler à celle-ci depuis la fonction onMessage ? (et garder le @SideOnly dessus)

[Vort3x_]

@robin4002

Bien je viens d’essayer ta suggestion, avec comme résultat un crash du serveur sauf que cette fois il ne pointe aucunes classes de mon mod

Ce n’est pas ton mod ça ?

EDIT : je crois que ce n’est pas le bon rapport de crash car il date de hier à 21h

[Vort3x_]

@robin4002 “com.mod” est bien mon chemin d’accès vers mon mod mais j’ai deux environement une ancienne version, avec le “com.vortex” et une avec “com.mod” j’utilise majoritairement la version “com.mod” vu que je suis en train de refaire une grosse partie du mod et donc je le fait dans deux environnements différents. Mais quand j’ai copier ma classe dans mon post, je n’avais pas Eclipse de lancer donc j’ai été dans ma backup sur ma clé USB qui contient la version “com.vortex” (Je me suis tromper de dossier en gros mais la classe est identique). Je ne sais pas si je suis très clair mais j’ai l’espoir que oui

Le crash que j’ai envoyer semblent en effet daté d’hier toutes mes excuses. Voici donc le plus récent :

Tu as quoi dans cette classe à cette ligne ?

[Vort3x_]

@robin4002 Et bien j’ai la ligne qui charge le paquet en question :

network.registerMessage(PacketUpdateDecalServer.Handler.class, PacketUpdateDecalServer.class, packetID++, Side.CLIENT);

EDIT : C’est d’ailleurs pour celà que je ne comprend pas vraiment ce qui fait crash, le rapport n’indique que cette ligne et donc une fois le contenue de la classe HANDLER (OnMessage) supprimer, le crash ne se produit plus.

[robin4002]

fais voir ton code actuel ?

Bonjour @robin4002,

Tout d’abord je tiens à m’excuser pour cette réponse tardive.

Ensuite, après avoir fait quelques tests, j’ai trouver la cause de ce crash j’ai récemment ajouter un “core-mod” dans mon mod pour pouvoir transformer la Classe Minecraft afin de changer la limitation de FPS dans le menu (30) hors j’avais mit en parametre de ce core-mod une exclusion

IFMLLoadingPlugin.TransformerExclusions({ "com.mod" }) ce qui corrige le crash serveur !
Je n’y avais pas penser plus-tôt et je me sent légèrement stupide.

En bref vraiment désolé de t’avoir fait perdre du temps mais peut-être que cela servira à quelqu’un.
