Kinematic Rigidbody doesn't lerp

Questions & Answers
1

I have a kinematic rigidBody whose position i control using its transform.

There is a point in the script where i do this :

transform.position = Vector3.Lerp(transform.position, targetPosition, 60f);

I Was using this code before adding a rigidbody to the object, and it was working fine.
Now with the RB it doesn’t lerp at all, it goes straight to targetPosition.

Doesn’t Lerp work with rigidBody ?

60F signifies the end of a lerp. The final value of Lerp should always be between 0 and 1, where 0 is the start and 1 is the end. I’d be surprised if it worked before, to be quite honest. I did the same things before I understood Lerp and it always jumped to the end.

Try doing:

            float _speedModifier = 2;       // How fast you want the RB to lerp
            float _allowedDistanceFromPos = 1; // How close you can be to the target position
            Vector3 targetPosition;
            Transform transform;

            void Update()
            {
                if (Vector3.Distance(transform.position, targetPosition) > _allowedDistanceFromPos)
                    LerpRB();
                else
                    _currMovementPos_Lerp = 0;  // Resets the lerp when you're close enough
                
            }

            float _currMovementPos_Lerp = 0;     // Holds a value to the current lerp "t" value.
            void LerpRB()
            {
                _currMovementPos_Lerp += Time.deltaTime * _speedModifier; // Adds the speed at which you want to move. 
                transform.position = Vector3.Lerp(transform.position, targetPosition, _currMovementPos_Lerp);
            }

That will give you much more desirable results. Just substitute your own fields, obviously.
