ArticulationBody.AddRelativeForce

파라미터

설명

Applies a force to the Articulation Body, relative to its local coordinate system.

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

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

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

Applying a force to an ArticulationBody wakes up that body. If the force size is zero then the ArticulationBody does not wake up.
Unit of measurement - N (newtons).
