Getting Started with Add-On Development for Bedrock Edition
Add-Ons are the first step on our journey towards bringing even greater levels of customization to Minecraft: Bedrock Edition. Add-Ons allow players to transform the look of their worlds and even change the behavior of mobs. For example, you can change the blast radius of a creeper and the texture it’s wearing.
In this tutorial, you will learn the following.
- The file structure used by Minecraft Add-Ons.
- Software used for editing JSON files.
- Extensions that are available to help with Add-On development.
When Minecraft is installed on your computer, there is a folder called com.mojang that is generated in the AppData folder. You will need to find this folder so you can add your content to it.
To locate the com.mojang folder on your computer, you will need to have Hidden items checkbox set to true, as shown below. while you're at it, go ahead and check the box for File name extensions, too.
Showing hidden items
- Open File Explorer from the taskbar.
- Select the View tab.
- In the Show/hide section, select the checkboxes for File name extensions and Hidden items.
- Press Win+R to open Run.
- Copy and paste the following into the Open field:
- Click OK.
Now would be a good time to save a shortcut to this folder on your desktop.
As shown in the image below, there are multiple subdirectories located within the com.mojang folder.
If you see more content in this folder than what is shown above, do not panic! This image shows a fresh install of Minecraft.
Behavior, Skin, and Resource Packs
There are three folders called behavior_packs, resource_packs, and skin_packs that will store finalized custom content that will be added to Minecraft: Bedrock Edition. Don't worry about these folders right now - you are going to be developing content, so you will be working in the development versions of these folders, as discussed in the next section.
You will use the development_resource_packs and development_behavior_packs folders for the Resource Pack and Behavior Pack tutorials. The development_skin_packs folder is used for developing skin packs. Development pack folders are updated each time Minecraft is launched so you can quickly load and test the changes you made to their contents.
minecraftWorlds contains each world that has been generated within the current build of Minecraft. Each folder will also contain resource and behavior pack folders to contain any packs that may be in use within the world.
It's recommended that when installing a new build of Minecraft, you should save a copy of this folder to use as a back up to prevent any potential loss of Minecraft Worlds that you may have.
Visual Studio Code
JSON is a popular text file format that is used by Minecraft: Bedrock Edition to interact with content. JSON can be edited in any text editor such as Notepad or Word. However, Visual Studio Code is a free to use text-based editor that supports third party extensions, including some built specifically for Bedrock development.

Visual Studio Code Extensions
Visual Studio Code supports extensions created by the Visual Studio Code developer community. Extensions are a great way to help write and understand Minecraft syntax when working on resource and behavior packs.

Now that your development environment is set up, you can start creating your first Add-On and learn more about resource packs.
