How to Create a giant Moshpit wit 600 Characters in Unity 3D
What do you do when you want to create a physics based sports game? You check out how many players you can add to your playfield!
Thats exactly what I wanted to achieve with my little experiment and the result was pretty amazing. You might have red the last Article about "Super Footbrawl" where I mentioned that I am using Puppetmaster for the Physics Animations and I still do. And thanks to Pärtels helpful optimization tips I managed to let 600 Characters run into a giant Moshpit. But lets start slowly!
The first test I did was 16vs16 which was not very complicated and runs smooth on a 16GB Ram i7 Macbook Pro from 2013.
The next step was 64vs64. I reduced some unused bones from my character (you don't really need finger bones for a character that has no fingers), messed around with the Fixed Timestemp value and uncommented some (for me) unused lines of code from puppetmaster. The result was a 64vs64 moshpit running on 30 FPS but with some screen capture magic I managed to record 60 FPS.
After that i continued the optimization stuff. I read threw every article I could found regarding Unity performance optimizations, batching, physics and optimized my character even more. But I aso needed something more powerfull than my Macbook. So I used the Power Machine of a friend - i7 5960X, 128GB Ram and a GTX 980Ti. Even if you are not so familiar with Hardware stuff I can tell you that this is the best you can get these days. So I made a build which boosted the performance again of course and we managed to get 30 FPS by a resolution of 640x360 and again, thank to some screen capture cheating I could capure it in HD with 60FPS.
And the result of all this? Unity is a damn powerful thing! I still want to keep the 5vs5 for Footbrawl but my curiousity was bigger than the actual use in this case.
