Introduction
As the title suggests, the recent 1.21.20 update is quite shocking.
The experimental feature “Holiday Creator Features” has been removed, making add-on creation significantly more challenging. This article explains how it has become difficult and how future add-on development will be affected.
You can also find a summary of this article on our YouTube video, so please check it out as well.
Explanation
First, let’s discuss the overview of the recent ver1.21.20 update.
Update Contents
The official announcement mentions the contents of the update. Although the article is in English, you will get the gist by taking a look.

At first glance, the addition of bundles and the elimination of bugs appear to be noteworthy improvements. In reality, most Minecraft YouTubers focus only on these positive aspects. Most Minecraft players are likely to focus on these positive features of the new version.
However, the following part cannot be ignored:
Quote from https://www.minecraft.net/ja-jp/article/minecraft-1-21-20-bedrock-changelog.
This indicates that “Holiday Creator Features” have been removed, causing all older add-ons that relied on this experimental feature to become non-functional.
Impact
“Isn’t that just an experimental feature?”
Do not underestimate this change. It significantly impacts the creation of original items. Older original items depended on the “Holiday Creator Features.” Without this feature, creating original items will become extremely difficult.
On the other hand, “API Scripts” are unaffected. As regular readers might know, API Scripts allow you to modify the game system of Minecraft Bedrock Edition using programming (JavaScript).
Surprisingly, “useless items” can still be created. These do not depend on Holiday Creator Features and continue to work by changing format_version to 1.20.0.
However, creating items with functionalities such as weapons, food, or any item that can be used becomes exceedingly difficult. The following chapters explain how to create such items after this update.
Future Add-on Development
To put it bluntly, the method for creating add-ons will change. As mentioned earlier, “API Scripts” will function, so inevitably, add-on development will transition to a base of “API Scripts.”
For example, I mentioned earlier that creating usable items would be difficult. When I said “difficult,” not “impossible,” I meant that item behavior can be controlled using “API Scripts.”
For instance, defining a function that fires when an item is used:
function item_use(item,command){
server.world.beforeEvents.itemUse.subscribe(ev => {
if (ev.itemStack.typeId == item){
ev.source.runCommand(command);
}
});
}
Moreover, as mentioned in the official announcement, using “Custom Components” is another method. This also relies on API Scripts and works even after the update. I plan to write a detailed article on Custom Components soon, so please wait for a bit.
Conclusion
As you can see, the 1.21.20 Minecraft update has profoundly shaken us add-on creators. While we must follow the developers’ lead, as the saying goes, “When in Rome, do as the Romans do,” I can’t help but feel a bit dissatisfied with the way this was handled. Am I the only one who feels this way?
