Minecraft Addons for Bedrock edition have the capability to add things such as blocks, items, sounds, and more. Questions should remain within the topic scope of the site, some more advanced multi-file things are off-topic. Use this for questions about development of certain aspects such as functions, LANG files, or certain aspects of the JSON involved, or use it for anything else that has to do with Minecraft addons.

Minecraft Addons are a way to add new blocks, items, sounds, and more to Minecraft Bedrock Edition on any platform Bedrock Edition is available on. Addons use an official JSON API, and, unlike mods, are not allowed to run code besides for a very limited JavaScript API only supported by Windows 10 Edition.
