Stay on Moving Platform without Character Controller

We are trying to make a character and other objects be able to stay on a moving platform for a 2d sidescroller. The moving platforms have their own tag called moving platform. We tried parenting the objects but they act crazy if the platform rotates or is at an angle. The player does not have a character controller. This is the script we have for the moving platform:

var targetA : GameObject; var targetB : GameObject; var speed : float = 0.1; function FixedUpdate () { var weight = Mathf.Cos(Time.time speed Time.deltaTime 2 Mathf.PI) 0.5 + 0.5; transform.position = targetA.transform.position weight + targetB.transform.position * (1-weight); } function OnCollisionEnter(hit : Collision) { if (hit.transform.tag == "Player") { hit.transform.parent = transform; } }

function OnCollisionExit(hit : Collision) { if (hit.transform.tag == "Player") { hit.transform.parent = null; } }
