Video of it working

If you just want to use the datapack in your own world, you can download it from the releases tab.

Use Minecraft snapshot 22w46a or higher.

I had to assign 20gb of ram to the game to get it to load my save with this datapack.

To play the animation run /function bad-apple:frames/frame-0. It'll play at 0, -60, 0, so it's best viewed on a superflat world.

If you just want the datapack, go to the releases tab.

Note - I'm currently doing some work on this, so the output is currently so large it's not possible to load the world. Until then, I suggest you use the old pre-generated datapack.

Make sure that the bad apple video is in the root folder (you have to download it yourself) and is named bad-apple-original.mp4.

Install opencv-python:

pip install opencv-python

Run process_video.py. You'll now have the video data in a JSON file called output.data. It's an array of frames. Each frame is a 2D array of pixels. The value 0 means that a pixel is black, 1 means that a pixel is white, 2 means that a pixel is grey..

Run generate_function.py. This will generate the frame files in the datapack template. Once it's done, copy the datapack into the datapacks folder of a Minecraft java edition world save.

Make sure you're running on Minecraft snapshot 22w46a or higher. I had to assign 20gb of ram to the game to get it to load with the datapack enabled, so be careful.

To play the animation run /function bad-apple:_play (you can also use /function bad-apple:_stop to stop the animation). It'll play at 0, -60, 0, so it's best viewed on a superflat world.
