DISCLAIMER ON AI USAGE (click to read)
Disclaimer on AI usage
I want to be as transparent as possible regarding my use of AI in this project.
I understand that many people are very critical of AI, and I am too. But I believe that AI can also be used very effectively.
If you find this topic important, please read the following explanation in its entirety.
This project is largely built using AI (Gemini 3 (partially also 3.5) Flash). This includes a significant portion of the code and the documentation.
Regarding the code:
Although a large part of the code is AI-generated, I understand how it works and operates. I know which systems and subsystems exist, how they function, and how they interact with each other. I don't claim that I could program the entire project myself, I lack the knowledge and, above all, the time. However, I do understand how my project works. Therefore, I am also able to test and debug these systems and solve problems myself.
Regarding documentation:
I'm really not good at writing documentation, as my thought processes and explanations often don't make sense to others. Therefore, I created the documentation and the associated generators for easy use with AI.
Conclusion:
In case anyone is wondering whether this disclaimer was also written with AI: no. I wrote it in my native language (German) and translated it into English using the classic Google Translate.
I understand if you don't want to use this project due to the intensive use of AI, or if you even actively dislike it. But it's important to me to be transparent and open. I also want to make it clear that all my other projects are not created with AI. I can code datapacks, I understand how datapacks work, and I can work with them (I often use the "Scythe" editor by the YouTuber "Craiy"). It was important to me to create a datapack that would make it easier for me to create my own datapacks or even worlds in the future.
I hope this explanation has clarified how and why I used AI.
What?
FuseBox is a datapack designed to simplify the development of other datapacks. FuseBox itself is a library datapack, meaning it doesn't do anything on its own. However, developers can use FuseBox to streamline the development of their own datapacks (or even entire worlds). FuseBox can also be installed as a mod, but for datapack development, I recommend the standard datapack version. FuseBox is currently in early development, so many more features and systems will be added in the future. Currently, there are four systems available: Stopwatch, Countdown, Actionbar Display, and Events.
To help using the pack, there is a full documentation which also includes simnple configurators for stuff like creating a stopwatch, registering an event etc.
Event system
With the FuseBox event system you can automatically execute commands or functions as a player when certain player based events happen, these include:
- onJoin
- onDeath
- onLeave
- onKillPlayer
- onKilledByPlayer
- onDamage
- onEntityKill
- whileOnline
- whileOffline
- onRightClick (with specified item)
- onHoldItem (with specified item)
You can register commands and functions to these events. Both will be executet as the player that triggered the event. Functions will also get the name of the player as an argument "$(player)".
Stopwatches & Countdowns
With FuseBox you can easily create intern stopwatches and countdowns and optionally show them to certain or all players in the actionbar. Almost every aspect of their appearance is configurable per stopwatch/countdown. You can use the configurator in the documentation to create all commands you need to create, show and pause the stopwatches/countdowns.
Actionbar Display
This is still very early in development, currently it's the system the stopwatches and countdowns use for displaying their data for selected or all players. Since everything here is controlled, it is possible to temporarily override the action bar for one or more players with custom text for a specific duration.
