ArticulationBody.AddRelativeTorque

参数

描述

Applies a torque to the articulation body, relative to its local coordinate system.

You can only apply a torque to an active ArticulationBody. If a GameObject is inactive, AddRelativeTorque has no effect.

ForceMode.Force and ForceMode.Acceleration modes modify the Angular Velocity Per Second accumulator and ForceMode.Impulse and ForceMode.VelocityChange modify the Angular Velocity Per Step accumulator. Mixing these 2 groups of ForceModes doesn't work for Articulation Bodies and will result in only the Angular Velocity Per Second accumulator being applied.

For more information on how ForceMode affects angular velocity, see Rigidbody.AddTorque.

Applying a torque to an ArticulationBody wakes up that body. If the torque size is zero then the ArticulationBody does not wake up.
Unit of measurement - Nm (newton-meters).
