How to reference a Player in unity

Question

The code (GameObject reference) doesn't show up so I need a different way to reference a player. I have not tried much though.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CamaraBehaviour : MonoBehaviour {
    public Object Player;
    public float yOffset = 3.0f;
    public float zOffset = 10.0f;
    Vector3 newPos = Player.transform.position;
    // Use this for initialization
    void Start () {
    }

    // Update is called once per frame
    void Update () {
        newPos.y = newPos.y + yOffset;
        newPos.z = newPos.z + zOffset;
        transform.position = newPos;
        transform.LookAt(player.transform);
    }
}

This is my camera fixing code. Which is why I need the reference in the first place. I thank you for the help (NO gmae written please the school blocks the word so if you reply with the word I wont be able to access the site).

Answer 1

The Player does not show up in the inspector because it's type, Object is not serializable. You want to use GameObject for Unity objects.

public GameObject Player;

You have a few other errors in this code.

1. You can't set the newPos using a reference to another object outside of a method. Do this in Update() instead.

    Vector3 newPos; // Update is called once per frame void Update () { newPos = Player.transform.position; // your other code }

2. There is a typo on the last line of update, where the P in Player needs to be capital (that's what you named your variable).

    transform.LookAt(Player.transform);

EDIT: However, since you only seem to be using the Player.transform anyways, you might as well go ahead and reference the transform component instead.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class CamaraBehaviour : MonoBehaviour {
    public Transform Player;
    public float yOffset = 3.0f;
    public float zOffset = 10.0f;
    Vector3 newPos;

    // Update is called once per frame
    void Update () {
        newPos = Player.position;
        newPos.y = newPos.y + yOffset;
        newPos.z = newPos.z + zOffset;
        transform.position = newPos;
        transform.LookAt(Player.position);
    }
}

If the script is attached to the player you can do this:

private GameObject player;

void Start()
{
    player = GetComponent<GameObject>();
}

However, you can make a public variable as demonstrated in the other answer by Marcus.

But... If you want to find the game object at runtime, you can also do this:

private GameObject player;

void Start()
{
    player = GameObject.FindWithTag("Player");
}

You just have to be certain to tag your player accordingly.
