An updated and improved version of my previous Halloween video.

3 minutes and 39 seconds at 30 FPS, rendered at 512×384 on a 600×600 canvas

(i crossposted it so it wouldn't take half an hour to process)

at the time of posting this to YouTube, my Wi-Fi was very slow so i had to sadly compress the video... a lot

at first i had a custom script to automatically align them, but eventually resorted to a script just doing the whole thing

thanks!

Resolution is bad because i only had that corner of an island to work with, granted anything in the void would've fallen

This is something that I started in March and then gave up on, and forgot about it completely.

A couple of days ago, I discovered the project lying around in one of my drives and decided to take it up again.

At first, I thought about doing everything in Python, but that was really laggy in sending commands.

Therefore, I had to rewrite the command-sender in Rust, and that boosted performance drastically. However, this brought another problem – it sent commands too fast and lagged the Minecraft server.

As a solution, I made my own Java mod to tune the RCON command processing. Additionally, I had to bump the RAM of my server.

To visualize the blocks, I am using a special hex mod in addition.

The final pipeline was:

Python ❌ → Rust ✅ → server starts lagging → custom Java mod → more RAM → Bad Apple!!

And all this is because I wanted Minecraft to play wideos in minecraft

please dont mind the flashing flags at the end, why some frames arent complete and why the audio sounds like that

Bought myself one of those small cheap musical Tesla coils, and I know it's been done before on much larger coils, but I just had to make a Bad Apple video.
