Les entités de bloc (TileEntity)

Kanar

Je sens que ce tutoriel va mettre utile !

Petite question par la même occasion, les TileEntity servent à faire des blocs conteneur comme les coffres, non ?

elias54

Aussi. Mais ils permettent de faire en sorte que le block ai une entité.

@‘Kanar’:

Je sens que ce tutoriel va mettre utile !

Petite question par la même occasion, les TileEntity servent à faire des blocs conteneur comme les coffres, non ?

Oui, car le contenu du coffre est sauvegardé dans le nbt tag.

Voila le tutoriel est terminé, je pense que je vais encore ajouter des détails demain, et il faut que je regarde encore la condition qui vérifie si le nom du joueur n’est pas le même n’a pas l’air de fonctionner, je sais pas pourquoi x)

MrCupCakeMonster

Super tuto !

robin4002

Je vais voir pour mieux détaillé les nbt avec les différents type de variable (faire un exemple pour tout)
Et je crois que je viens de trouver pourquoi la vérification du nom du joueur marche pas :
if(!visiteur[0].equals(playerName));
Ne me demandé pas pourquoi j’ai mis ce point virgule, mais il a rien à faire la, c’est surement pour ça que ça fail, je vais voir ça dès que je suis sur mon bon pc.

En effet, c’était ça

JustPingo

Salut !

J’ai un souci. Pour tester, j’ai recopier ton programme qui ressort les joueurs, mais au right-click ça crash. J’ai mis des System.out.println et j’ai remarqué que le code ne crash que lorsque j’appelle te.quelquechose(). Pourtant, j’ai vérifié, et hormis le nom des class, j’ai exactement le même code. Pourrais-tu m’aider ?

Merci d’avance !

PS : Voici le crash-log (La class du TileEntity est TileEntityPeripheral et celle du block est BlockComputerTerminal):

Le tileEntity est bien enregistré ? La méthode pour créer le tileEntity est bien au dessus de celle du clic droit ?

JustPingo

Ouai, j’ai bien fait la GameRegistry dans la class principale.

Voici le code de la TileEntity :

:::

package mods.virtualcraft.common;

import net.minecraft.nbt.NBTTagCompound;
import net.minecraft.tileentity.TileEntity;

public class TileEntityPeripheral extends TileEntity
{
public String visiteur[] = new String[]{"visiteur0", "visiteur1", "visiteur2", "visiteur3", "visiteur4"};

public void readFromNBT(NBTTagCompound nbtTag)
{
super.readFromNBT(nbtTag);
for(int i = 0; i < 5; i++)
{
visiteur* = nbtTag.getString("visiteur" + i);
}
}

public void writeToNBT(NBTTagCompound nbtTag)
{
super.writeToNBT(nbtTag);
for(int i = 0; i < 5; i++)
{
nbtTag.setString("visiteur" + i, visiteur*);
}
}

public String getPlayerList()
{
return visiteur[0] + ", " + visiteur[1] + ", " + visiteur[2] + ", " + visiteur[3] + ", " + visiteur[4] + ", ";
}
public boolean addPlayerToList(String playerName)
{
System.out.println("6");
if(!visiteur[0].equals(playerName))
{
System.out.println("7");
for(int i = 3; i >= 0; i–)
{
System.out.println("8 : "+i);
visiteur _= visiteur*;
}
System.out.println("9");
visiteur[0] = playerName;
}
System.out.println("10");
worldObj.notifyBlockChange(xCoord, yCoord, zCoord, 2);
return true;

La méthode pour créer le tileEntity est bien au dessus de celle du clic droit ?

ça ne change rien vu que ce sont des méthode @Override donc c’est le positionnement dans les superclasse qui est important

Sinon essaie de remplacer ça:


}
return true;

par ça:


return true;
}
else
{
return false
}

JustPingo

Même résultat, crash à l’appel d’une fonction de la TileEntity.

J’ai essayé de faire un @Override sur les fonctions dans la TE pour celle pour lequel ça pourrait être utile, mais aucune amélioration.

robin4002

Je viens de regarder ton code, en fait ton bloc n’a pas de tileEntity :

@Override
public TileEntity createNewTileEntity(World world) {
return null;
}

Cette méthode doit bien être en null car c’est la méthode vanille de minecraft, mais tu n’a pas mit la méthode de forge (qui prend un compte les métadata) :

@Override
public TileEntity createTileEntity(World world, int metadata)
{
if(metadata == 0)
{
return new TileEntityTutorial();
}
else if(metadata == 1)
{
return new TileEntityTutorial2();
}
else
{
return null;
}
}

Tu peux aussi utiliser un switch(metadata) vu que j’ai vue que tu les aimes bien ^^

JustPingo

Ah ok, merci, j’avais pas regardé le contenu de cette fonction, je pensais qu’elle ne servait que s’il y avait des metadatas.

Effectivement, j’aime bien les switchs
Ça fonctionne, merci !

bonjour je remonte le sujet car j’aimerais savoir plus le tileEntity mais pour la 1.7.2 j’ai 3 ou 4 erreur sur le code fourni que je n’arrive pas a resoudre, je sais qu’il y a eu quelque changement entre la 1.6 et 1.7, si possible robin que tu fasse un tuto plus précise sans utiliser les blocks metadata , sa m’aiderais énormément!. merci d’avance ^^

Un nouveau tutoriel 1.7 est prévu.
Les méthodes n’ont pas changés en 1.7, c’est toujours

public TileEntity createTileEntity(World world, int metadata)
{
return new TileEntityPrivateChest();
}

et

public boolean hasTileEntity(int metadata)
{
return true;
}

çà doit etre tout bete , mais y a t’il moyen de détecter un click droit directemetn dans le tile entity , sans passer par la class du block ?
