I made a rework into a system of zones delimited by splines, far better for level design. No more tedious grids to manage !
Leaves can be moved out of zones and return once the animation is finished. 🥰

OK so it was not a culling issue, but a CPU bottleneck ! Now at close range the simulation runs smoothly.
With the introduction of VATs, I lost the auto-LOD, so now the GPU is struggling when too much units are in FOV. 😅

I didn't expect at all to go this far with this christmas side project...
And now I am totally thinking of rebuilding my own game around this tech and it changes everything how I would design it. 🙃

They are billions ! (not really but it's a nice game I recommend)
100k VATs moved by Unity ECS with a flow field, on a 500x500m map, at 30+ FPS ! 🤪
But I suspect a culling issue (FPS does not increase when zooming in)

As expected using 3D models with animator massively decrease perfs (no LODs here, but that will not solve the issue).
The most optimal approach would be to use VATs, but I never implemented it until now. 😅

50k units with avoidance ! 👀
That's funny, because adding avoidance improves performances, making a lot of the units waiting their turn to move (to display 100k units, I would need a far bigger map to spread them)

Fully functional resizing system !
It's a little sluggish with such a large area (+100 FPS for 70k sheets, which is still acceptable).
But I'll limit the size of the areas eventually, so it's not a concern. 😋

Calculations via ECS + GPU batching, it'll spawn tens of thousands of leaves for breakfast ! 😎

You have no idea how lucky you are not to know what a quaternion is, and how much of a pain it is to rotate objects in 3D space... 🙃

I have my continuous wind effect.
However, performance-wise it's terrible... I'll have to brainstorm on my architecture to find a solution (hashmaps are cool, but I can't randomily pick a leaf in them) 🧐

And if I set the tornado's rotation speed to 0, I can generate a kind of underground explosion effect or an antigravity well effect depending on how long I hold it. It's just so cool. 😱

So, here's what I completely reworked:
- an automated spawn system around the player, adaptable based on performance (before, it was a fixed spawn point across the entire map)
- dynamic grid management using HashMaps, automatically reassigned when the leaves move

Well, I don't think I could do any better in terms of performance, and I'm going a bit overboard with the leaves quantity and their speed. 😅

Let me show you a system I worked on :
using Unity ECS, a leaf interaction simulation with a casting spell system.
Each leaf is an entity animated through an ISystem, using AnimationCurves.

It took me an absurdly long time to create this spawn effect + separate the materials by herd + maintain the batching.
The effect is a bit heavy on the FPS side, I'll have to rework it, but it works as intended.

Actually, by adding a bit of randomness to the sheep's movements/idleness, the rendering seems sufficient to me and it runs smoothly (there are 200 of them there).
