Java / bukkit：在runnable中运行“For”方法1次？

Question

所以我有这段代码：

                           ProtectedRegion region = WGBukkit.getRegionManager(p.getWorld()).getRegion("afk1mine");
                       Vector max = region.getMaximumPoint();
                       Vector min = region.getMinimumPoint();
                           for (int i = min.getBlockX(); i <= max.getBlockX();i++) {
                                 for (int j = min.getBlockY(); j <= max.getBlockY(); j++) {
                                   for (int k = min.getBlockZ(); k <= max.getBlockZ();k++) {
                                     final Block kasamas = Bukkit.getServer().getWorld("paradise").getBlockAt(i,j,k);
                                         //Bukkit.getPluginManager().callEvent(new BlockBreakEvent(kasamas, p));
                                         p.sendMessage(" kitas: " + kasamas); 
                                   }
                                 }
                               }   

我确实只想为第一个块发送消息，然后在1秒内重复runnable并发送第二个块的消息等。

您需要增加BukkitRunnable 中的坐标。像这样的东西会起作用，虽然我承认它看起来不太好。

BukkitRunnable sendMessage = new BukkitRunnable() {
    final int minI = min.getBlockX(), minJ = min.getBlockY(), minK = min.getBlockZ();
    final int maxI = max.getBlockX(), maxJ = max.getBlockY(), maxK = max.getBlockZ();
    int i = minI, j = minJ, k = minK;

    @Override
    public void run() {
        final Block kasamas = Bukkit.getServer().getWorld("paradise").getBlockAt(i, j, k);
        p.sendMessage(" kitas: " + kasamas);
        if (k > maxK) {
            if (j > maxJ) {
                if (i > maxI) {
                    cancel();
                } else {
                    i++;
                    j = minJ;
                    k = minK;
                }
            } else {
                j++;
                k = minK;
            }
        } else {
            k++;
        }
    }
};
sendMessage.runTaskTimer(plugin, 0, 20);

这假设p是effectively final;否则，您可能需要创建一个有效的最终变量捕获它。将plugin替换为插件类的实例。
