I made some swarm controllers for my 2D underwater universe.
It was kind of a struggle at first, but rather because my coding experience isn’t that great. so I had to repeat some concepts for days until they clicked. but now I really like the workflow. Not quite sure about the execution order. In my example I had something slightly different in mind but swayed to a more simple approach which I might have consolidated in a single object and tree. But for now these are 2 different Objects both with their own simzones. So I wonder which one is executed first each frame.
I also made some simple hairy tentacles for my jellyfish with sim nodes that have inertia and sway in the water, needs a lot more work though.
- I never use the delta time. It’s just not useful for my projects as far as I can tell.
- I don’t know if that is already possible: I would really like to have a node that would give access to system time, so I could make the procedures a little less deterministic.
- I had some strange behaviour, when I baked stuff to cache. In the end I had to delete the cache folders by hand so it wouldn’t crash and to show the correct GN solutions.
(nothing to do with simulation nodes, but is anyone else having a blank icon in the windows taskbar for the latest few alphas? And I’d like a new splash screen for the alpha, too 
Sprite fright is great and also 2 years old 
Sorry, didn’t want to make these a forum topic anywhere )
