      Bonjour ou peut-être rebonjour 🙂
      Je suis depuis plusieurs heures face à un problème d’event que je n’arrive pas à corriger malgrès mes nombreuses tentatives.

      Voici le code de mes events:

      @SubscribeEvent
   public void onDrops(BlockEvent.HarvestDropsEvent event)
   {
       if(event.block == Blocks.dirt && event.harvester.getHeldItem() != null)
           event.drops.clear();

      @SubscribeEvent
   public void onDrops(BlockEvent.HarvestDropsEvent event)
   {
       // Dirt
       if(event.block == Blocks.dirt && event.harvester.getHeldItem() == null)
       {
           event.drops.add(new ItemStack(ModResetcraft.Dirtdust, 1));
       }

      Avec ces codes, le bloc de terre détruit à la main fait crasher le jeu, alors qu’il devrait donner 1 Dirtdust.

      Je les ai séparer en deux car ils sont chacun dans une classe différente (Je n’arrivais pas à mettre le .clear avec le .add dans la même classe, l’eventbus de celle de .clear est dans preInit et cette de .add dans postInit), ce que je n’ai pas dit c’est que ce code marchait très bien les premières fois que je vérifiais mon mod.

      Si quelqu’un pourrait me dire où est le problème s’il le voit (je cherche encore de mon coté mais je commence à tourner en rond), je lui en remercie  🙂

        Essaies comme ceci et dis moi

        
@SubscribeEvent
public void onDrops(BlockEvent.HarvestDropsEvent event)
{
if(event.block == Blocks.dirt && event.harvester.getHeldItem() != null)
{
event.drops.clear();
}
else if(event.block == Blocks.dirt && event.harvester.getHeldItem() == null)
{
event.drops.add(new ItemStack(ModResetcraft.Dirtdust, 1));
}

          Il nous faudrait le rapport de crash.
          Et je ne comprends pas pourquoi tu sépare ton code en deux classes …

            Merci de vos réponses ^^
            Julot - Le jeu ne crash plus, c’est déjà ça, mais ce n’est pas encore bon… le bloc donne 1 Dirtdust et 1 bloc de terre en plus. Je vais essayer de modifier un peu ça voir si j’arrive à quelque chose, mais je suis toujours ouvert à d’autres propositions 🙂

            Robin - Voilà:

            Je met deux classes car je n’arrivais pas à mettre le .clear et le .add dans le même event, mais je l’ai fais quand j’ai commencer les events et je n’avais toujours pas modifier ça ^^___Bon et bien, problème résolu 🙂
            Voici le code:

            @SubscribeEvent
   public void onDrops(BlockEvent.HarvestDropsEvent event)
   {
       // Dirt
       if(event.block == Blocks.dirt && event.harvester.getHeldItem() == null)
       {
           event.drops.clear();
           event.drops.add(new ItemStack(ModResetcraft.Dirtdust, 1));
       }
       else if(event.block == Blocks.dirt && event.harvester.getHeldItem().getItem() != null && event.harvester.getHeldItem().getItem() == ModResetcraft.Shovel)
       {
           event.drops.clear();
           event.drops.add(new ItemStack(ModResetcraft.Dirtdust, 4));
       }

            Merci! ^^

              Tu as un NPE, donc quelque chose est null.
              En fait tu cherche à faire quoi exactement ? Que la terre drop rien sauf si on casse à la main est dans ce cas ça drop de la poussière/poudre de terre ?

              ÉDIT : ok j’ai compris, en passant je fusionne tes deux messages (pas de double poste merci).
