How to change your Minecraft world’s biomes


This happened to me the other day: I have this awesome Minecraft world (my main map), on which I’ve built a bunch of awesome cities with a few friends. Now, the problem arose when I decided that I wanted to build a snow-themed village. You see, my map doesn’t have any snow biomes within a few thousand blocks of the spawn point. Since there was no way in hell that I would start over on a new map, I set off to fin a way to change an existing Mineraft world’s biomes.

Let’s say we have this nice little map that we want to change into a snow world:

Minecraft world without snow

The first thing we need to do is to download and install a program called WorldPainter, which is available here:

Once WorldPainter is finished installing, open it. Then, go to File->Import->Minecraft map… and select your world’s level.dat file.

Note: On Windows, singleplayer maps are generally stored in the “C:\Users\<username>\AppData\Roaming\.minecraft\saves” directory.

Then, select the “do not mark any chunks read-only” option and click Ok. Once the map has finished loading, you’ll see something similar to this:

Now, in the layers pane, click the “Biomes” button. You can then select a biome in the biomes pane. In this case, i’ll select the “Cold Taiga” biome, because I want snow.

Select biomes in worldpainter

Note: If you’re unable to see the entire biome list, you can click on the arrow button in the top right corner of the biomes pane:

Toggle floating biomes pane

Once you’ve selected the desired biome, you can simply “paint” the biome on your world by holding left-click and dragging your mouse.

When you’re satisfied with your changes, go to File->Merge with Minecraft map… Then select the “Only change the biomes” option and click Merge.

Once the merge is finished, you should be able to fire up Minecraft and enjoy your new biomes!

That’s (one way) to change your Minecraft world’s biomes.

Enable cheats on an already existing world in Minecraft


The other day, I was playing on an old Minecraft singleplayer map when I encountered an unfortunate problem: I wanted to change some of the map’s gamerules, but I was unable to do so because cheats were disabled. Having spent several hours on this map, I didn’t want to start over, so I decided to try and find a way to enable cheats on an already existing world.

When you save a Minecraft world, the game creates a level.dat file that contains all of the map’s parameters in NBT (Named Binary Tag) format. Now, if we want to change these parameters, we can use an awesome little program called NBTExplorer (available for download on this forum thread:

How to enable cheats using NBTExplorer:

First off, you need to download NBTExplorer either by looking up the forum thread linked previously or by going to this page:


Once NBTExplorer is finished downloading, you can open it by clicking on NBTExplorer.exe (the icon is a small dead shrub). You should then see a list of your singleplayer maps:


Now, you need to double click on the map for which you want to enable cheats.

Once this is done, double click on level.dat [1 entries], then Data: 24 Entries, and finally on AllowCommands: 0

This will open a small text box titled “Edit value…” in which you need to type 1.


You can then click on Ok and save your changes by going to File -> Save (or by pressing Ctrl+S). You should now be able to use cheats on your Minecraft map!

I hope this article helped you out and, as always, have a nice day!


How to disable fire spread in Minecraft


You know when you build a nice fireplace in Minecraft:


And THIS happens?

fire buring

Yeah, Minecraft’s way of handling how fire spreads makes close to no sense. This is the reason why, in most of my maps, I just disable it altogether. But how do you do this? It’s actually very simple.

Keep in mind that, If you’re playing on a singleplayer map, you need to have cheats enabled to use this procedure and if you’re on a server, you’ll probably need to be an admin. Note that if you don’t have cheats enabled, you can turn them on by following this procedure:

If these conditions are met, open the chat box and type the following command:

/gamerule doFireTick false

This will permanently disable fire spread on the map or server. If you ever wish to re-enable fire spread, simply type:

/gamerule doFireTick false

That’s it! I hope this post helped you out!




How to easily fix flowing water in Minecraft


Don’t you just hate it when this happens? I know I do…

water 1

It just ruins an otherwise perfect landscape…

So how do we fix flowing water in Minecraft? In this post, I’ll show you two methods to do this.

First Method – The vanilla way.

If you’re adamant on using vanilla Minecraft, then there’s no easy way to fix flowing water. The best method is to make a dirt “bridge” over the affected area and to dump buckets of water underneath is, like this:

water 2




Unfortunately, this method is cumbersome and takes an eternity… so here’s an easier water to fix flowing water in Minecraft:

Second Method – WorldEdit to the rescue:

Instead of playing around with buckets for a good ten minutes, I strongly recommend you use WorldEdit. WorldEdit is a plugin for CraftBukkit servers that can also run on single player maps (If you don’t know how to do this, you should check out this tutorial).

When you have WorldEdit installed, all you need to do is to follow these instructions:

  1. Stand in the water next to the problematic blocks. You need to be one block deep.
  2. In the chat, type /fixwater radius, where radius is a number that corresponds to the radius in which the water will be corrected (If the affected area is large, then put in a large value.). Per example, you could type /fixwater 10, and this would fix any flowing water within ten blocs of you. Then press enter.
  3. There is no third step! easy eh?

How to easily remove a forest in Minecraft


I can’t count how often this has happened to me: I want to build an epic city in Minecraft, but I first have to clear a huge forest. The small trees aren’t so bad to cut, but the large ones are… well, you know…

So, is there an easy way to clear a forest in Minecraft? In survival, unfortunately not. BUT, if you’re willing to use third-party tools, there are two easy methods to get rid of those pesky trees.

Using a world editing plugin (WorldEdit or VoxelSniper):

This is my favourite way to quickly get rid of forests, but it only works if you host your world on a CraftBukkit server. The first thing you’ll need to do is to install WorldEdit or VoxelSniper, then, use these commands:

For WorldEdit:

Type //brush <brush type> air <brush size>

Per example: //brush sphere air 5

Then, type //mask leaves

What this does is create a spherical brush that replaces every “leaves” bloc with air.

You can now spam right-click around the area you wish to clear to remove all the leaves:

Removing leaves with WorldEdit

Now, all that’s left to do is to remove those pesky logs. Type //mask log and spam right-click once more:



For VoxelSniper:

Removing trees with VoxelSniper is similar to removing trees with WorldEdit, but the commands differ.

You first need to type /v air, then /b b mm.

You then need to select a brush size by typing /b <size> (per example, /b 10)

Finally, type /vr leaves

Now, put an arrow in your hand and spam right-click over the area to clear:

Remove leaves with voxelsniper

Once you’re done removing the leaves, type /vr log and right-click over the area to clear:

Remove logs with voxelsniper


So that’s how you remove forests with world-editing plugins. Now, this method is nice and simple, but it doesn’t work if you don’t have a Craftbukkit server. If this is the case, then you might want to consider the second method.


Using MCEdit:

MCEdit is a superb Minecraft world editor. It allows you to move around parts of the map, create structures and more. Here, I will show you how you can clear all the trees in an area with this program.


First off, load the world by clicking on “Open a level…” and then navigating to your world’s “level.dat” file.

You then need to select the region that you want to clear:

Select part of the map - MCEdit


Then, click on “Fill and Replace”, then on “Ok”, then on “Replace”.

Under the “Find” option, select leaves, and under the “Replace with” option, select air. Once this is done, click replace.

This should remove all the leaves in the selected area (Keep in mind that you might need to do this for all the different types of leaves in the area). You now need to remove the logs.

To remove the logs, repeat the steps above, but under the “Find” option, select Wood instead of Leaves, then click replace (Once more, keep in mind that you might need to repeat this process for all the types of wood in the area).


When you’re satisfied with the result, save the map (Ctrl+S) and close MCEdit!


So that concludes this article, I hope you enjoyed it!
