      Salut a tous j’ai créer un petit mode de cimetière qui quand on appuie sur le bouton respawn on est tp au biome sky le plus proche.
      Mais malheureusement j’ai un crash que je ne comprend pas…

      la classe cimetière:

      
package CoeCemetery;

import net.minecraft.entity.Entity;
import net.minecraft.entity.EntityLivingBase;
import net.minecraft.entity.player.EntityPlayer;
import net.minecraft.util.ChunkCoordinates;
import net.minecraft.world.World;
import net.minecraft.world.biome.BiomeGenBase;
import net.minecraftforge.event.ForgeSubscribe;
import net.minecraftforge.event.entity.EntityJoinWorldEvent;

public class CemeteryZone
{

private ChunkCoordinates findClosestBlockOfBiome(Entity e, BiomeGenBase b, double radius)
{
World w = e.worldObj;
double min = Double.POSITIVE_INFINITY;
ChunkCoordinates current = null;
for(double x = -radius; x <= radius; x += 0.5)
{
for(double z = -radius; z <= radius; z += 0.5)
{
double dist = Math.sqrt(Math.pow((e.posX - (int)Math.floor(x + e.posX)), 2) + Math.pow((e.posZ - (int)Math.floor(z + e.posZ)), 2));
if(w.getBiomeGenForCoords((int)Math.floor(x + e.posX), (int)Math.floor(z + e.posZ)) == b && dist <= radius && min > dist)
{
min = dist;
current = new ChunkCoordinates((int)Math.floor(x + e.posX), 0, (int)Math.floor(z + e.posZ));
}
}
}
return current;
}

@ForgeSubscribe
public void onRespawn(EntityJoinWorldEvent event)
{
System.out.println("CemeteryZone");
System.out.println();
EntityLivingBase entity = (EntityLivingBase)event.entity;
if(GuiDeath.mort == true)
{
if(entity instanceof EntityPlayer)
{

if(((EntityPlayer)entity).capabilities.isCreativeMode == true)
{
return;
}

else if(((EntityPlayer)entity).capabilities.isCreativeMode == false)
{
BiomeGenBase location = event.entity.worldObj.getBiomeGenForCoords((int)event.entity.posX, (int)event.entity.posZ);

System.out.println("testrespawn");
System.out.println(GuiDeath.mort);
ChunkCoordinates biomeLocation = findClosestBlockOfBiome(((EntityPlayer)entity), BiomeGenBase.sky, 100);
entity.setLocationAndAngles(biomeLocation.posX, 250, biomeLocation.posZ, entity.rotationYaw, entity.rotationPitch);
System.out.println("GuiDeath tp Cemetery");
}
}
}
}
}

      l’appuis du bouton (GuiDeath):

      
if(par1GuiButton.id == 1)
{
this.mc.thePlayer.respawnPlayer();
this.mc.displayGuiScreen((GuiScreen)null);
mort = true;

}

      le crash report:

        EntityLivingBase entity = (EntityLivingBase)event.entity;
        Déjà la c’est pas bon, tu vas avoir un CastException si l’entité n’est pas une EntityLivingBase.

        @ForgeSubscribe
public void onRespawn(EntityJoinWorldEvent event)
{
System.out.println("CemeteryZone");
System.out.println();
if(GuiDeath.mort == true)
{
if(entity instanceof EntityPlayer)
{
EntityPlayer player = (EntityPlayer)event.entity;
if(player .capabilities.isCreativeMode)
{
return;
}

else if(!player.capabilities.isCreativeMode)
{
BiomeGenBase location = event.entity.worldObj.getBiomeGenForCoords((int)event.entity.posX, (int)event.entity.posZ);

System.out.println("testrespawn");
System.out.println(GuiDeath.mort);
ChunkCoordinates biomeLocation = findClosestBlockOfBiome(player), BiomeGenBase.sky, 100);
player.setLocationAndAngles(biomeLocation.posX, 250, biomeLocation.posZ, player.rotationYaw, player.rotationPitch);
System.out.println("GuiDeath tp Cemetery");
}
}
}
}
}

        C’est déjà plus propre comme ça.
        Après tu as un NPE, donc a mon avis il n’a trouvé le biome voulu dans la fonction findClosestBlockOfBiome.
