Disabling and enabling the motor (with a rigidbody attached to) on a ramp makes the motor move permanently

[h-shokri]

When we disable the PlatformerMotor2D to handle the physics by the Rigidbody2D and then again enable the PlatformerMotor2D to gain the control of the character, the rigidbody velocity should be zeroed otherwise the character will tend to move around using the previous velocity.
I have inserted a line of code in PlatformerMotor2D.OnEnable() and that solves my problem:

private void OnEnable()
{
        if (_rigidbody2D != null)
        {
	        _velocity = _rigidbody2D.velocity;
		_rigidbody2D.velocity = Vector2.zero; //I have added this to solve the problem.
                _originalKinematic = _rigidbody2D.isKinematic;
                _rigidbody2D.isKinematic = true;
        }
}
