A few years ago I needed a net simulation for a soccer game (not a fifa-like realtime game, more like tactic/turn based stuff). Unity had just removed cloth-rigidbody interaction from their built-in cloth, so there was no way to have the net and the ball react to each other. The ball would just pass trough it. So I implemented my own cloth, and over time it became Obi:

(Note this video is quite old, things have improved considerably since then).
Thanks for the attention. The result on this video seems pretty cool already IMO...
Quote:It took me like 4-6 weeks to get the basic stuff working. However, getting things like performance and user experience to acceptable levels took me around 2.5 years. If you have the time, resources and drive, by all means try to do it yourself. It's a lot of fun and you'll learn heaps. I've gathered all material anyone can need to build their own engine, a list of all research articles I used is available on the webpage: http://obi.virtualmethodstudio.com/references.html
Well, I'm not a too passionate programmer, I mean, it's cool build things and make them work and everything. But I believe it isn't my favorite part of process, considering that some subjects are painful to be learned. While I do have some time, I must focus in the right things to make my project keep going, so I can't afford spend too many time in such a small session of the game...
Quote:If you decide to use Obi, it will do most of the work for you. You do need to understand some basic stuff about 3D: how meshes and transforms work, what's the difference between local and world space, and a few other things, but I think you'll be fine.
Well, Considering what you said, Obi is my best chance to get this thing working without losing a ton of time researching on my own, I wish I had such good solutions as Obi for some harder problems that I have no clue how to solve either....
Quote:No problem. This is called tunneling (https://www.youtube.com/watch?v=ms0Z35GY6pk).
Obi implements continuous collision detection (via speculative contacts), it should be pretty robust. I've also recently added surface collisions to prevent small objects from slipping trough gaps in between cloth particles, so collision detection is continuous both temporally and spatially: https://www.youtube.com/watch?v=9LXeIem4gvM
Nice demonstration and explanation about tunneling...

Take your time reading it and poke around, I can answer any questions you might have.
Yeah, I started to read some initial topics, after the purchase, I'll continue to read the docs and learn how to use it.
Bye man.
