Re: [simspark-devel] Joint feedback with multithreaded ODE

[Qingyuan Z. <mi...@gm...>]

Hi Sander,
I am new here, and I 'm appreciated if you can offer help.

I have tested this, it works fine. I played a game in 9VS9, seems nothing
wrong happened.
BTW, where can I see the joint feedback?

Regards,
Qingyuan Zhang
