FluidForceSensor

Inherits from: SensorBase → Instance → Object

FluidForceSensor is a SensorBase which outputs the results of fluid force simulation from the last physics frame for the part it is attached to. The sensor outputs the Force, Torque and CenterOfPressure which were computed by the fluid force simulation on the last physics frame.
