Moving camera with player in 2d
Hi
I'm new to unity and I'm trying to write a script for my camera move my it with the player object. Hoever, I found I cannot use the "transform.player" because unity can't recognize player as a Ridgidbody2D with position for some reason. Someone might see how I solve this, i.e. getting hold of the player position?
using UnityEngine;
using System.Collections;
public class Camerafollow : MonoBehaviour
{
// Use this for initialization
void Start ()
{
}
// Update is called once per frame
void Update ()
{
Rigidbody2D player = Instantiate(GameObject.Find ("Player")) as Rigidbody2D;
Vector2 hastighet = player.velocity;
if (hastighet != 0) {
Vector2 playerpos;
playerpos.x = transform.player;
playerpos.y = transform.player;
transform.position = playerpos;
}
}
}
Instantiate() creates a new player, so your code is creating a new player every frame. What you want to do is get a reference to the player in Start(), then use that reference to position the camera. Something like:
using UnityEngine;
using System.Collections;
public class Camerafollow : MonoBehaviour {
private Transform player;
void Start () {
player = GameObject.Find ("Player").transform;
}
void Update () {
Vector3 playerpos = player.position;
playerpos.z = transform.position.z;
transform.position = playerpos;
}
}
Thank you that worked perfectly. I noticed the behavior seemed to be the same when the camera is a child to the player object. Is that correct?
I'm close to do what I want, your example helps me a lot, but imagine this, I want that the camera follows my character at the same height, I mean, the same coordinate "y" and only when my character has arrived at the middle of the screen, then, the unique coordinate I want to move is "x", if I apply the example you put, the screen goes down and it starts to move since the beginning of the program.
I tried to assign values to the coordinate "x" in this way:
void LateUpdate ()
{
Vector3 Finnpos = Finn.position;
Finnpos.z = transform.position.z;
if (Finnpos.x >= transform.position.x)
transform.position.x = Finnpos.x;
//transform.position = Finnpos;
}
But unity says: Cannot modify a value type return value of `UnityEngine.Transform.position'. Consider storing the value in a temporary variable
Can you help me?
You should ask this as a new question, not as a 'Solution' to an existing question. As for the error, you need to do:
if (Finnpos.x >= transform.position.x)
Vector3 v = transform.position;
v.x = Finnpos.x;
transform.position = v;
}
But this snipped does not take a look at the larger tracking issue, only solves the compiler error.
Tested and worked!!! Sorry for my english.
1 - Create an Game Object with name "Player"
2 - Create an Game Object with name "Boundary Markers"
-
Create a game object with name "Left Marker" into Boundary Markers
-
Create a game object with name "Right Marker" (and change a Transform position x for 25 Right Markers's ) into Boundary Markers
3 - Create script "Camera Follow"
using UnityEngine; using System.Collections;
**public class CameraFollow : MonoBehaviour {
public Transform player;
public Transform farLeft;
public Transform farRight;
void Update () {
Vector3 newPosition = transform.position;
newPosition.x = player.position.x;
newPosition.x = Mathf.Clamp(newPosition.x, farLeft.position.x, farRight.position.x);
transform.position = newPosition;
}
}**
4 - Attached Game Object Player on player
5 - Attached Game Object Left Marker on farLeft
6 - Attached Game Object Right Marker on farRight
