Thank you, aron!
I've just tried the beta version, the RVO system became very simple and easy to use.
However, it doesn't solve the obstacle problem.
And what worse is my RVO agent becomes a little jitter in the movement:(not very obviously but really annoying. I already checked off the Double Buffering option). And my character is moved by call SetTarget function in every frame which set the goal pos to the mouse position, and used var movementDelta = RVO.CalculateMovementDelta(Time.deltaTime); to calculate the desired pos.I noticed there are not any interpolate function in the rvo simulator anymore, maybe it could be the problem?
The RVO system is really import for my project, I would be very appreciate if you can give me some advice, Thanks in advance!
