Configurable config.yml

Hi, i'm trying to make a plugin which converts obsidian to lava. But now, I can't seem to figure out how to use the config.yml. Basically, what I'm trying to do is this:
Admin goes into config.yml and changes some random variable or whatnot to (for example)6.
Player makes obsidian, so he gets lava.
Player repeats 6 times a s shown above.
Player fails again, and therefore cannot change obsidian back to lava again.

Code:

package me.epiccraft21.core;

import org.bukkit.Material;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.EventHandler;
import org.bukkit.event.Listener;
import org.bukkit.event.block.Action;
import org.bukkit.event.player.PlayerInteractEvent;
import org.bukkit.inventory.ItemStack;
import org.bukkit.plugin.java.JavaPlugin;

public class Main extends JavaPlugin implements Listener{
   
    @EventHandler
      public void onClickBlock(PlayerInteractEvent e) {
          Player p = e.getPlayer();
          if (p.getItemInHand().getType().equals(Material.BUCKET)) {
          if (e.getAction().equals(Action.RIGHT_CLICK_BLOCK)) {
              Block b = e.getClickedBlock();
              if (b.getType().equals(Material.OBSIDIAN)) {
                  if (p.getItemInHand().getAmount() > 1) {
                      p.getItemInHand().setAmount(p.getItemInHand().getAmount() -1);
                      p.getInventory().addItem(new ItemStack(Material.LAVA_BUCKET));
                      b.setType(Material.AIR);
                  } else {
                      p.getInventory().remove(p.getItemInHand());
                      p.getInventory().addItem(new ItemStack(Material.LAVA_BUCKET));
                      b.setType(Material.AIR);
                  }
              }
          }
      }
   }
}

Help is appreciated!
BTW: I also don't know how to make or use the config.yml, this is my first time doing so.

 

Have you tried reading the tutorial on the wiki?

 

@EpicCraft21

http://wiki.bukkit.org/Configuration_API_Reference

 

Yes, I read over it but I can't seem to find what i'm looking for.

 

@EpicCraft21 What were you looking for in it?

 

Basically how to make a config.yml, how to get the server owner to be able to change the data, and using that data to set a limit.

 

@EpicCraft21

 

Yes?

 

@EpicCraft21 Read what I quoted.

 

I did, I'm asking what chapter I'm supposed to read, as I don't understand anything because I never used or seen a config.yml before.

 

@EpicCraft21 Read everything, if you don't understand that then you should learn java before.

 

Ok.

I know java, just not config.yml itself.

 

@EpicCraft21

Then that page explains everything you need to know about it.

 

The config api reference won't show you how to do that ^^^ but it can show you how to get values from the config. Also the Bukkit documentation can show you how to get values from the config as well. http://jd.bukkit.org/rb/apidocs/org/bukkit/configuration/MemorySection.html
