[Physics Engine Update | Fabric Mod]
Linear and angular velocity calculations are done.
It's unbelievable how much easier everything is with Java as compared to Datapacks. No fixed point scaling, no hardcoding every cross product for optimization, multiple ops per line... ❤️

[Physics Engine Status Update]
I just started developing a server-side mod that I can use as a reference (for figuring out the scaling and other things more easily).
Here's the entity I set up in the past 2 days.

Minecraft snapshot 25w41a won't let us grab the result of a stopwatch query, so I wrote a small datapack that uses binary search to get it.
(It'll definitely be a regular feature in the next snapshot)

It's a tiny bit more stable now. The 2 core problems are:
- Due to calculation inaccuracies, impulses overcorrect, reinforcing the next problem:
- Impulses make it hard for all 4 corners to touch the ground simultaneously. If not all 4 corners do, it can wiggle back and forth

[Disclaimer: A lot of bugs were temporarily resolved with ugly code that only works for testing]
Found a TON of bugs and temporarily fixed them, but it's still very jittery and a bit buggy. Not sure what's causing that.

Made a temporary ugly fix for a bug in contact generation, and it looks a lot more stable now. I can be pretty sure that any bugs in this clip are from velocity resolution now.

I don't know why, but I think there might be a calculation error somewhere.

Finished for world_axis_y and fixed some bugs. It can now resolve multiple contacts per tick, too!
Will work on penetration resolution next, so the object doesn't clip into the ground xD.

(It currently doesn't update other contacts' values based on the resolved contact. It also doesn't resolve penetrations yet.)

Started working on the resolver.
Linear velocity change is calculated correctly for this specific axis (VERY early test).
Angular part and penetration resolution are still missing, and ofc making it work for all other axes. This is just a test to see if the formulas are correct.

I think we're onto a winner (Efficiently and correctly detects whether it should invert the contact normal & penetration depth)

Almost all preparations for the resolver are done (& I made some cool optimizations), but I have to work out a last problem with a sign-error for edge-edge contacts.
I think I figured out the correct way now, so all the preparation should be done today.

Optimized the ray intersection logic so it can stop after finding a single valid intersection per object. This change makes this part of the code ~3-4% faster, but it's nigh unmeasurable due to it already being very fast.
Also, exam season is over and I've prepared some resolution pseudocode 👀

In general, the chapter managed to pull my heartstrings on more than one occasion from there. Ralsei's "Look, I'm smiling" was absolutely heartbreaking given his arc throughout Ch3/4 and interacting with the gravestone at the end was bittersweet. I was tearing up like thrice.

I've spent the last 8 hours without breaks on reworking TimeLib from scratch. I'm tired, but I'm also very happy. It's a lot better than before, in my opinion.

[Minecraft Datapack Update]
In an upcoming update for my TimeLib library, time will stay synced even at incredibly low or high tickrates.
You won't be able to tell from the timer that the game isn't running at 20 TPS!

Hitting the object now works with the new system, though the calculations are still a bit janky (Will need to replace some of them later on).

Full Hitbox Overhaul ✨
A small hitbox now spawns where you're looking.
- Depends on your entity interaction distance (Max 5 blocks)
- Extremely efficient
- Gets rid of stray interaction entities caused by the player leaving or the chunks unloading
