Problems with the forced generation of the world

I have a small problem. I wanted to write a plugin that can force sgenenrirovat area of the world (saving me from having to walk most of the world that he created). However, I have a problem, and I can not understand it is my mistake or a bukkit `s bug.

If my mistake (which I have little doubt), please explain what am I doing wrong?

Thanks in advance.
I was found that the bug occurs when the 52 lines from the file "generator.yava."

By far easier to do this without a command. Simply load and get all chunks you need.

Code:

int locationX = 20;
int locationZ = 30;
int chunkX = locationX >> 4;
int chunkZ = locationZ >> 4;
world.getChunk(chunkX, chunkZ);

GetChunk will automatically load or generate this chunk if needed. (how else can he get a chunk?)

Simple algoritm I used to get chunks around a player in a square pattern and set a flag on them

Code:

    public static void handleMove(Location from, Location to) {
        if (from.getWorld() == to.getWorld()) {
            int cx = toChunk(to.getBlockX());
            int cz = toChunk(to.getBlockZ());
            if (toChunk(from.getBlockX()) == cx) {
                if (toChunk(from.getBlockZ()) == cz) {
                    return;
                }
            }
            //Handle it
            int radius = Bukkit.getServer().getViewDistance();
            cx -= radius;
            cz -= radius;
            radius *= 2;
            World w = to.getWorld();
            long time = System.currentTimeMillis();
            for (int a = 0; a < radius; a++) {
                for (int b = 0; b < radius; b++) {
                    int chunkX = cx + a;
                    int chunkZ = cz + b;
                    if (w.isChunkLoaded(chunkX, chunkZ)) {
                        touch(w.getChunkAt(chunkX, chunkZ), time);
                    }
                }
            }
        }
    }

 

Thank you. I'll try this method.

upd.
Thanks again. This method really works. (all genius is simple)
