make minecraft wait

[jjw123]

hi, so i need to make minecraft wait before running code, all the methods that i have tried cause unbelievable amounts of lag, so im just wondering what other ways i have of doing it, i want something like the BC quarry building

ive tried threads, ill try more thread methods...

i still cant get one to work without Producing MASSIVE lag

 

heres my code example

 

public static Runnable r1 = new Runnable() {
    	public void run() {
    		try {
    			while (true) {
    				System.out.println("Hello, world!");
    				Thread.sleep(5);
    			}
    		} catch (InterruptedException iex) {}
    	}
    };

    public static Thread t1 = new Thread(r1);

public static void creation(World world, int depth, int height, int width, int x, int y, int z, Block block){

	for (int x1 = 0; x1 < depth; x1++) {
		for (int y1 = 0; y1 < height; y1++) {
			for (int z1 = 0; z1 < width; z1++) {
				// Floor
				world.setBlockWithNotify(x + x1, y, z + z1, block.blockID);
				t1.start();
			}
		}
	}
}

 

im probably making such a noobish mistake, for which i apologise in advanced

try a tick counting function to will only do a task every so many ticks to reduce lag. There are 20 ticks on average in a second and a tick is every single world update.

Can you give me a little example of how to do that? like what class i can look at to figure it out?

private int ticks = 0;

onUpdate()
{
    if(ticks % 20 == 0)
   {
      System.out.println("one second!");
   }

   ticks ++;
}

so i guess that method will overwrite another method? what class is the first method in it thats true.
