Question by abhishek7 · Apr 09, 2016 at 05:16 PM · simplethis

"This" not available in the current context

Why?

 using UnityEngine;
 using System.Collections;
 
 public class HillScript1 : MonoBehaviour
 {
     bool direcright = true;
     public float speed = 5.0f;
     public float leftpoi = this.transform.position.x - 4;
     public float rightpoi = this.transform.position.x;
     // Use this for initialization
     void Start()
     {
         
     }
 
     // Update is called once per frame
     void Update()
     {
         
         if (direcright)
         {//x<1.4, x>4
             GetComponent<Rigidbody2D>().velocity = new Vector2(-speed, 0);
             if (transform.position.x <= leftpoi)
             {
                 direcright = false;
             }
         }
         else {
             GetComponent<Rigidbody2D>().velocity = new Vector2(speed, 0);
             if (transform.position.x >= rightpoi)
             {
                 direcright = true;
             }
 
         }
 
         }
     }

You cannot declare things outside of a function like that. Simple things like a boolean or public float speed = 5.0f; are fine but when you start using references, getting positions and using math operators it isn't going to work.

Change it to this:

 public float leftpoi;
 public float rightpoi;
 
 void Start()
 {
      leftpoi = gameObject.transform.position.x - 4;
      rightpoi = gameObject.transform.position.x;
 }

You can remove 'this' entirely or leave it in if you want. this.gameObject is the same as gameObject though. You can remove the gameObject too but personally I like to leave it in for clarity in case you are also using the transform from another object.
