Lock Character to Z axis.

I have a basic script that allows me to move on the X and Y(jump). I want to run a check that the character is always on a certain Z axis. I have tried the transform.position.z = 20; but that gives me a “Cannot modify type value” error.

Here is the code in using (similar to CharacterController.Move sample code)

using UnityEngine;
using System.Collections;

public class characterController2D : MonoBehaviour {
    
	public float speed = 6.0F;
    public float jumpSpeed = 8.0F;
    public float gravity = 20.0F;
	
    private Vector3 moveDirection = Vector3.zero;
    
	void Update() {
	
        CharacterController controller = GetComponent<CharacterController>();
		
		
		
		// If character is on the ground
		if (controller.isGrounded) {
            moveDirection = new Vector3(Input.GetAxis("Horizontal"), 0, 0);
            moveDirection = transform.TransformDirection(moveDirection);
            moveDirection *= speed;
            
			//Jump from grounded position
        	if (Input.GetButtonDown("Fire1")){
                moveDirection.y = jumpSpeed;	
			}
        }
		
		if(!controller.isGrounded){
			moveDirection.x = Input.GetAxis ("Horizontal");
			moveDirection.x *= speed;
		}
			
        moveDirection.y -= gravity * Time.deltaTime; //
		print (moveDirection.z);
        controller.Move(moveDirection * Time.deltaTime); //
    }

}

In c# transfrom.position.z is marked as readonly. You can do this:

transform.position = new Vector3(transform.position.x, transform.position.y, 20);
