CM 3 - Modify Cinemachine Spline Cart speed parameter by script

Unity Engine
,
2

The spline cart doesn’t directly know about the speed because the Auto-dolly is implemented using an abstract interface so that custom auto-dolly algorithms can be made.

You can do something like this:

var autodolly = cart.AutomaticDolly.Method as SplineAutoDolly.FixedSpeed;
if (autodolly != null)
{
    autodolly.Speed = 1;
}
