first select the platform and then
go to component > physic > box collider

@blackdragonstory,

You have to give the platform a collider and a rigid body. Same to the (character?) or whatever you want to not fall through it.

I´ll try but I think I made that :D
Is there any diference if object(player) has animation?
Cuz I created a sphere(for movement)2 sphere(for animation) and object.
Soo sphere2 and object are under sphere1...and object is umder sphere 2 :D
I´ll check and post results soon :)

It doesnt work here move sript :
/// This script moves the character controller forward
/// and sideways based on the arrow keys.
/// It also jumps when pressing space.
/// Make sure to attach a character controller to the same game object.
/// It is recommended that you make only one call to Move or SimpleMove per frame.
var speed : float = 6.0;
var jumpSpeed : float = 8.0;
var gravity : float = 20.0;

private var moveDirection : Vector3 = Vector3.zero;
function Update() {
var controller : CharacterController = GetComponent(CharacterController);
if (controller.isGrounded) {
// We are grounded, so recalculate
//move direction directly from axes
moveDirection = Vector3(Input.GetAxis("Horizontal"), 0,
Input.GetAxis("Vertical"));
moveDirection = transform.TransformDirection(moveDirection);
moveDirection *= speed;
if (Input.GetButton ("Jump")) {
moveDirection.y = jumpSpeed;
}
}
// Apply gravity
moveDirection.y -=gravity * Time.deltaTime;
// Move the controller
controller.Move(moveDirection * Time.deltaTime);
}

Btw I noticed that player falls trought only when you dont move it...if you move it then it works perfectly...what could be the problem?

I am sorry that I bothered you cuz I tried now with third person controler and it works :)
I am soo happy:D
