我正在用Bukkit用Java编写Minecraft SkyGrid Generator.When im使用cobblestone为每个块，它工作正常。但是，当我试图获得一个随机块，生成器运行到一个错误。这是我的代码。
@Override
public ChunkData generateChunkData(World world, Random random, int ChunkX, int ChunkZ, BiomeGrid biome) {
ChunkData data = createChunkData(world);
Material material = Material.COBBLESTONE;
for(int x = 0; x < 4; x++) {
for(int z = 0; z < 4; z++) {
for(int y = 0; y < world.getMaxHeight() / 4; y++) {
boolean foundBlock = false;
while(!foundBlock) {
int i = random.nextInt(Material.values().length);
material = Material.values()[i];
if(material != null && !material.isLegacy() && material.isBlock() && material != Material.AIR) {
foundBlock = true;
}
}
System.out.println(material);
data.setBlock(x*4, y*4, z*4, material);
}
}
}
return data;
}
正如你所看到的，我把材料打印到了控制台里 但这并没有给我任何信息，因为有些块似乎会导致错误，但有时它们工作正常，另一个块似乎会导致错误。这里是控制台打印的情况。
