Pour moi il a l’air de manquer des déclarations pour une dalle double et un simple

LeBossMax2

Tu n’as pas bien définit ton BlockStateContainer (Ou alors tu ne l’a peut-être pas définit.) Tu doit le faire en redéfinissant la méthode BlockStateContainer dans la classe de ton block.

huggets

@‘LeBossMax2’:

Tu n’as pas bien définit ton BlockStateContainer (Ou alors tu ne l’a peut-être pas définit.) Tu doit le faire en redéfinissant la méthode BlockStateContainer dans la classe de ton block.

C’est qu’il n’y a même pas cette méthode de définit dans la classe BlockSlab, ducoup je ne sais pas comment la définir

SpyMan

Cette method est definie dans la class block. Comme blockslab est extendba bloxk alors ta la method

huggets

Il n’y a pas de méthode BlockStateContainer, il a juste une méthode setBlockState (je ne me rapelera plus de son nom) de type BlockStateContainer. Je vais essayer de lire encore plus en détails le code source et je vous dirai si j’a réussi à faire ce que je voulais

Superloup10

C’est bien la bonne méthode.

LeBossMax2

Ah oui désolé, je voulais dire la méthode createBlockState.

huggets

Bon je n’y arrive toujours pas :

J’ai toujours cette erreur et je ne sais pas ce qu’il faut faire ;(

java.lang.IllegalArgumentException: Don't know how to convert mt:copper_slab[seamless=true,variant=copper] back into data..

LeBossMax2

Il faut aussi override les methodes getMetaFromState et getStateFromMeta pour que le monde puisse enregistrer ton block.

Ok, j’essayerai demain.

Par contre, je n’ai pas trop compris à quoi cette annotation sert et ce qu’elle fait.

Superloup10

Tu parles de quelle annotation ?

huggets

@‘Superloup10’:

Tu parles de quelle annotation ?

L’annotation @Override

AymericRed

Elle a aucun effet sur le code mais permet d’indiquer à celui qui code qu’ellle “remplace” la fonction du même nom et de mêmes paramètres de la classe mère.

Superloup10

Pour être plus exact, elle indique au compilateur que la méthode que tu veux redéfinir existe ou pas, ensuite ton IDE lui va t’indiquer visuellement si c’est le cas ou pas.

huggets

Ok mais ducoup je ne vois pas a quoi ça sert d’override les deux méthodes si ça ne fait rien au code

LeBossMax2

Quand je dis qu’il faut override la méthode, ça veut dire réécrire la méthode et accessoirement mettre l’annotation @Override pour être sûr de ne pas s’être trompé dans la signature de la fonction. (ps pour ces deux fonctions, il y a des explications et un exemple ici)

@‘huggets’:

Attention, tu confonds l’action d’override et l’annotation @override (ce n’est pas la même chose).
Le fait d’override une fonction (passer outre en français) consiste à réécrire l’action d’une fonction.

Prenons deux classes, la classe Block et la classe BlockSlab (qui hérite de Block) pour rester dans le thème de cette discussion.
La classe Block contient la méthode suivante :

public int getMetaFromState(IBlockState state)
    {
        if (state.getPropertyKeys().isEmpty())
        {
            return 0;
        }
        else
        {
            throw new IllegalArgumentException("Don't know how to convert " + state + " back into data…");
        }
    }

BlockSlab va également hériter de cette fonction, qui réalisera la même action.
Donc si j’appelle la méthode getMetaFromState de Block ou de BlockSlab, dans les deux cas cela fera la même chose (c’est à dire retourner le metadata 0 si le blockstate n’a pas de propriété, déclenché une erreur sinon car il ne sait pas comment convertir les états en metadata).

Si maintenant je mets dans ma classe BlockSlab la fonction suivante :

public int getMetaFromState(IBlockState state)
    {
        int i = 0;
        i = i | ((BlockStoneSlab.EnumType)state.getValue(VARIANT)).getMetadata();

        if (this.isDouble())
        {
            if (((Boolean)state.getValue(SEAMLESS)).booleanValue())
            {
                i |= 8;
            }
        }
        else if (state.getValue(HALF) == BlockSlab.EnumBlockHalf.TOP)
        {
            i |= 8;
        }

        return i;
    }

qui a le même nom et la même signature (c’est aussi une fonction qui retourne un int et qui prend en argument un IBlockState) alors lorsque je vais appeler getMetaFromState de BlockSlab cela va cette fois-ci utiliser cette fonction et non celle qui se trouve dans Block. J’ai donc autre passé la méthode getMetaFromState de la classe Block.

L’annotation @Override permet de s’assurer que l’on a pas fait d’erreur. Par exemple si en voulant outre passé la méthode getMetaFromState je fais ceci :

public String getMetaFromState(IBlockState state)
    {
        return "Bonjour";
    }

Cela ne fonctionnera pas car la signature n’est pas bonne (le type de retour est String et non int comme dans Block.java). Et je ne vais pas forcement me rendre compte tout de suite de l’erreur. Idem si j’avais par exemple écrit par mégarde public int getMetaFromStat(IBlockState state) (sans le e de la fin).

@Override va permettre demander au compilateur de déclencher une erreur si la fonction n’existe pas dans la classe mère (ou dans la classe mère de la classe mère, etc.).

   @Override
    public String getMetaFromState(IBlockState state) // erreur, String getMetaFromState(IBlockState) n'existe pas dans l'héritage
    {
        return "Bonjour";
    }

Cela est très pratique pour éviter les erreurs et cela l’est également lors des mises à jours de Minecraft (cela permet de voir plus vites quelles méthodes n’existent plus ou lesquels ont désormais une signature différente).
