    • addToPhysicsSystem

      public void addToPhysicsSystem(EActivation activation)
      Add bodies and constraints to the physics system and optionally activate the bodies.
      Parameters:
      activation - whether to activate bodies (not null)

    • driveToPoseUsingKinematics

      public void driveToPoseUsingKinematics(SkeletonPose pose, float time)
      Drive the ragdoll to the specified pose by setting velocities.
      Parameters:
      pose - the desired pose
      time - time to achieve the pose (in seconds)

    • driveToPoseUsingKinematics

      public void driveToPoseUsingKinematics(SkeletonPose pose, float time, boolean lockBodies)
      Drive the ragdoll to the specified pose by setting velocities.
      Parameters:
      pose - the desired pose
      time - time to achieve the pose (in seconds)
      lockBodies - (default=true)

    • driveToPoseUsingMotors

      public void driveToPoseUsingMotors(SkeletonPose pose)
      Drive the ragdoll to the specified pose using motors.
      Parameters:
      pose - the desired pose (not null, unaffected)

    • getBodyCount

      public int getBodyCount()
      Count how many bodies are in the ragdoll, which is unaffected
      Returns:
      the count (≥0)

    • getBodyIds

      public int[] getBodyIds()
      Enumerate all bodies in the ragdoll, which is unaffected. (native method: GetBodyIDs)
      Returns:
      a new array of body IDs

    • getConstraintCount

      public int getConstraintCount()
      Count how many constraints are in the ragdoll, which is unaffected.
      Returns:
      the count (≥0)

    • getPose

      public void getPose(RVec3 storeRootOffset, Mat44Array storeJointMatrices)
      Copy the low-level pose using a locking body interface.
      Parameters:
      storeRootOffset - storage for the root offset (not null, modified)
      storeJointMatrices - storage for the joint matrices (not null, modified)

    • getPose

      public void getPose(RVec3 storeRootOffset, Mat44Array storeJointMatrices, boolean lockBodies)
      Copy the low-level pose.
      Parameters:
      storeRootOffset - storage for the root offset (not null, modified)
      storeJointMatrices - storage for the joint matrices (not null, modified)
      lockBodies - true → use the locking body interface, false → use the non-locking body interface (default=true)

    • getRootTransform

      public void getRootTransform(RVec3 storeLocation, Quat storeOrientation)
      Copy the transform of the ragdoll's root, using the locking body interface. The ragdoll is unaffected.
      Parameters:
      storeLocation - storage for the root location (not null, modified)
