Simple Elevator

Hi I am new in Unity3d and i was trying to make a simple 2d side scroller with the standard assets.
So I was trying to make a simple Elevator out of a cube so i was trying to animate the cube that it goes up and down so the side scroller can go up or down. But i noticed that the side scroller falls throw the cube so i tried to script the elevator with vector3.up but the side scroller falls still throw the cube, but an other cube with an rigid body won't fall throw it.
Does anyone know how to do an simple elevator for the side scroller?

Thanks for any help.

 

When the player enters the area of an elevator, parent the player to that elevator object. Then moving the elevator will move the player along with it. When he exits the area, unparent the player.

 

How do you parent or unparent objects via script ?

 

transform.parent = elevator.transform; //Parents the elevator gameobject to the gameobject the script is attached to
transform.parent = null; //Makes this gameobject have no parent

 

PlayerObj = GameObject.Find("Player");

PlayerObj.transform.parent = GameObject.Find("Elevator");



unparent :

PlayerObj.transform.parent = PlayerObj.transform;

= null also works as noted above.

 

Does it work too if you let a big cube rotate, so that the player doesn't go throw the rotated cube
Or does it work without pairing too?
Because objects with rigidbodys attached collides with the elevated so can you attach an rigid body behavior to the player because if i put an normal rigid body to the player, it goes throw the normal cubes too
