Générer des minerais

robin4002

Remplace dimensionID par dimensionId
Pour le reste je sais pas.

Ryken

sa change rien, bon bah je vais abandonner

robin4002

Eclipse te donne quoi comme erreur ? (le nom de l’erreur).

Ryken

pour les virgules : Syntax error on token “,”, ; expected
pour le world.provider.dimensionId : world cannot be resolved to a variable
pour le generateNether : void is an invalid type for the variable generateNether

Si ce n’est pas bah je sais pas je n’est que cela.

robin4002

En fait j’avais pas fait attention, la classe était completement fausse niveau accolade. Prend celle-ci :

package shaarfight.worldgen;

import java.util.Random;
import shaarfight.common.ShaarMod;
import net.minecraft.block.Block;
import net.minecraft.init.Blocks;
import net.minecraft.world.World;
import net.minecraft.world.chunk.IChunkProvider;
import net.minecraft.world.gen.feature.WorldGenMinable;
import cpw.mods.fml.common.IWorldGenerator;

public class IlluveWorldGeneration implements IWorldGenerator
{
@Override
public void generate(Random random, int chunkX, int chunkZ, World world, IChunkProvider chunkGenerator, IChunkProvider chunkProvider)
{
switch(world.provider.dimensionId)
{
case -1:
this.generateNether(world, chunkX * 16, chunkZ * 16, random);
break;
}
}

private void generateNether(World world, int x, int z, Random rand)
{

for(int i = 0; i < 1; i++)
{
(new WorldGenMinable(ShaarMod.oreIlluve, 0, 5, Blocks.netherrack)).generate(world, rand, x + rand.nextInt(16), rand.nextInt(120), z + rand.nextInt(16));
}
}
}

Plus aucune erreur cependant mon minerai ne se genere toujours pas je comprend pas.

}

Ryken

Merci sa marche mais quelle est la rareté du quartz ?

Diangle

je ne me rappelle plus dans quel classe elle est mise désoler, tu devrais regarder dans le code de la dimension

RedRelay

Ce qui me dérange, c’est ta notation avec les apostrophes.
Les apostrophes sont réservé pour les chars donc pour moi, ça porte a confusion de mettre tes “variables du tutoriel” entre apostrophe.

Squix

Bon tutoriel (un peu rapide quand même) mais Agabou, tu as oublié de mentionner une classe de minecraft bien sympatique, BlockOre. Voilà pour ma part comment je fait la déclaration de mon minerai (si ça peut aider quelqu’un pour la dureté du minerai par exemple) :


cookieOre = new BlockCookieOre(Material.rock).setBlockName("cookieOre").setResistance(5.0F).setHardness(3.0F).setStepSound(Block.soundTypePiston).setBlockTextureName(MODID + ":cookie_ore")

Et la classe BlockCookieOre :


//Les imports

import java.util.Random;
import com.squixdev.cookieparty.common.CookieParty;
import net.minecraft.block.Block;
import net.minecraft.block.BlockOre;
import net.minecraft.block.material.Material;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.init.Blocks;
import net.minecraft.init.Items;
import net.minecraft.item.Item;
import net.minecraft.world.World;

public class BlockCookieOre extends BlockOre {

public BlockCookieOre(Material p_i45394_1_) {
super();
// TODO Auto-generated constructor stub
}

//ici on retourne l'item droppé
public Item getItemDropped(int p_149650_1_, Random p_149650_2_, int p_149650_3_)
{
return Items.cookie;

}
//ici on retourne la quantité droppée
public int quantityDropped(Random p_149745_1_)
{
return 4 + p_149745_1_.nextInt(5); //j'utilise ici un random pour faire varier la quantité (ici égale au Lapis)
}
//ici on gère ce qui ce passe après que le bloc ait été détruit (s'exécute avant OnBlockDestroyed) - (totalement optionnel)
@Override
public void onBlockHarvested(World p_149681_1_, int p_149681_2_,
int p_149681_3_, int p_149681_4_, int p_149681_5_,
EntityPlayer p) {

p.addStat(CookieParty.achievementCookieMiner, 1);

super.onBlockHarvested(p_149681_1_, p_149681_2_, p_149681_3_, p_149681_4_,
p_149681_5_, p);
}
//ici on gère l'outil minimal requis (valeurs de minecraft : net.minecraft.item, rechercher "ToolMaterial")
@Override
public void setHarvestLevel(String toolClass, int level) {
// TODO Auto-generated method stub
super.setHarvestLevel(toolClass, 1);
}

@Override
public Block setHardness(float p_149711_1_) {
// TODO Auto-generated method stub
return super.setHardness(p_149711_1_);
}

}

@Squix
Oui, utile mais pas plus que sa car 90 % des fonction sont rapide autrement que sa, sinon pense a renomme tes argument das les fonction, sinon quand tu coderas des chose 1^48 plus complexe tu ne t’y retrouvera plus.

agabou

Voilà, j’ai modifié mon tutoriel et il supporte maintenant la génération avec métadata, ainsi que dans le Nether et dans l’End !

robin4002

Je vais m’occuper de la version en vidéo, ajouter les balises aller et ancre pour qu’on puisse cliquer sur le sommaire, puis je vais le valider.

Bonjour , j’ai des erreurs pour la générations de mon minerais ,

this.addOreSpawn(CinabreOre, 0, Blocks.stone, world, random, x, z, 16, 16, 7, 18, 13, 45);

N’est pas au bon endroit …

guillaume5001

Il faut le mettre où est merci de ta réponse ?

robin4002

C’est écrit dans le tutoriel, et n’importe qui sachant programmer sait où le mettre.

guillaume5001

Ok j’ai su où le placer et merci a vous mais quand je lance le jeu , le jeu se lance mais quand je vais en solo est que je génère une map mon jeu crash voici les logs :
