Unity3D Make moving platform

THIS IS C# scrip: GOOD 4 2D GAMES AND 3D GAMES !

 * for waypoints, simple use an empty gameObject parented the the object. Tag it "Waypoint", and number them in order */







---------------------------------------------------------------------------------

AND THIS IS BONUS EXTRA SCRIPT THAT IS NOT IN VIDEO .
THIS WILL STICK PLAYER 2 PLATFORM
OPEN NEW C# AND COPY PAST THIS :
THEN ADD THIS 2 YOUR PLATFORM .
--------------------------------------------------------------------------------

using UnityEngine;
using System.Collections;

public class HoldCharacter : MonoBehaviour {

void OnTriggerEnter(Collider col) {
col.transform.parent = gameObject.transform;
}

void OnTriggerExit(Collider col) {
col.transform.parent = null;
}
}
