Question by Dijit · Mar 30, 2014 at 01:22 AM · cameravector3

Problems Scripting a Camera

I'm trying to make a camera that follows a player character, but not exactly. First off I tried to make a script that would follow the player from an exact distance, I figured I could change it later. However It doesn't work?

 using UnityEngine;
 using System.Collections;
 
 public class Camproper : MonoBehaviour {
 
     public Transform target;
     int distance = -10;
     int lift = 2;
 
     // Update is called once per frame
     void Update () {
 
         transform.LookAt (target);
         transform.position = (target.position +    Vector3(0,lift,distance));
 
     
     }
 }

Upon running t$$anonymous$$s script i Receive an error,

"Assets/Camprpopr.cs(14,65):error CS0119: Expression denotes a 'type', where a 'variable', 'value' or 'method group' was expected"

T$$anonymous$$s is extremely confusing to me, it seems it has a problem with "(target.position + Vector3(0,lift,distance))" and its saying that it requires a value. So I figured It might have a problem with my variables. To test that I rewrote the line to '(target.position + Vector3(1,1,1))', but the same error log persisted.

Why isn't vector3 accepting my variables/values?

Also I was t$$anonymous$$nking to only make the camera move when the player is a certain distance away. So if (Camera(x)- player(x))> 5 transform.Translate(Vector3.x + 1); So that the camera would only follow if the distance from it exceeded a set value

But I don't if/how to get the x variable out of the "transform" or "transform.position" Is there a way to get those numbers out so I could set 6 different floats(CamX,CamY,CamZ,TargetX,TargetY,TargetZ)

You need the 'new' keyword in C# when creating a Vector3:

 transform.position = (target.position +   new Vector3(0,lift,distance));

You can get the 'x' variable out by:

 transform.position.x

Note the typical way of doing the distance calculation is to do:

 if (Vector3.Distance(target.position, transform.position) < someValue) {
     // Do somet$$anonymous$$ng.
 }
