Ton gui handler ne devrait pas être mélangé avec ton proxy.

[SCAREX]

C’est tout à fait possible si c’est bien fait

[robin4002]

Oui mais c’est source d’erreur, donc vaut mieux éviter.
S’il y a ré-implémenté les fonctions en mettant return null dans le client proxy, ça expliquerai le souci.

Si ce n’est pas le cas, je pense que le gui handler est tout simplement pas enregistré.

Ah d’accord néanmoins cela crash encore, je pense que j’ais mal réalisé ma classe :

}

[SCAREX]

Où as-tu enregistré ton gui handler ?

[yveslefou]

@‘SCAREX’:

Où as-tu enregistré ton gui handler ?

Dans ma classe principal avec :

MinecraftForge.EVENT_BUS.register(new GuiHandler());

FMLCommonHandler.instance().bus().register(new GuiHandler());

[AymericRed]

Ceci ne vas pas l’enregistrer comme GuiHandler mais comme classe d’évents, normal que ça ne marche pas. Il faut faire NetworkRegistry.INSTANCE.registerGuiHandler(new GuiHandler());

[yveslefou]

Merci à tous
