Spawn error
I don't know why these errors pop up, I am using unity 4.5.2
here is the code
using UnityEngine;
using System.Collections;
public class GameController : MonoBehaviour
{
public Camera cam;
public GameObject egg;
private float maxWidth;
void Start ()
{
if (cam == null)
{
cam = Camera.main;
Vector3 upperCorner = new Vector3 (Screen.width, Screen.height, 0.0f);
Vector3 targetWidth = cam.ScreenToWorldPoint (upperCorner);
float eggWidth = egg.renderer.bounds.extents.x;
maxWidth = targetWidth.x - eggWidth;
StartCoroutine (Spawn ());
}
IEnumerator Spawn() // error
{
yield return new WaitForSeconds(2.0f);
while (true)
{
Vector3 spawnPosition = new Vector3 (
Random.Range(-maxWidth,maxWidth),
transform.position.y,
0.0f
);
Quaternion spawnRotation = Quaternion.identity;
Instantiate (egg, spawnPosition, spawnRotation);
yield return new WaitForSeconds (Random.Range(1.0f, 2.0f));
}
}
}
} //error
please tell me what to do??? when i remove the last bracket it says only one error about Spawn(), but then the syntax of the code is not in the proper correct form.

You don't close function Start(). I change full your script:
public Camera cam;
public GameObject egg;
private float maxWidth;
void Start () {
if (cam == null) {
cam = Camera.main;
Vector3 upperCorner = new Vector3 (Screen.width, Screen.height, 0.0f);
Vector3 targetWidth = cam.ScreenToWorldPoint (upperCorner);
float eggWidth = egg.renderer.bounds.extents.x;
maxWidth = targetWidth.x - eggWidth;
StartCoroutine (Spawn ());
}
} //close function
IEnumerator Spawn() {
yield return new WaitForSeconds(2.0f);
while (true) {
Vector3 spawnPosition = new Vector3 (Random.Range(-maxWidth,maxWidth), transform.position.y, 0.0f);
Quaternion spawnRotation = Quaternion.identity;
Instantiate (egg, spawnPosition, spawnRotation);
yield return new WaitForSeconds (Random.Range(1.0f, 2.0f));
}
}
Check all "{" and "}". They count is match. I hope that it will help you.

i am faceing an error of renderer.bounds.extents help me here any one?
using System.Collections; using System.Collections.Generic; using UnityEngine;
public class GameController : MonoBehaviour { public Camera cam; public GameObject egg;
private float maxwidth;
// Use this for initialization
void Start () {
if (cam == null) {
cam = Camera.main;
}
Vector3 upperCorner = new Vector3 (Screen.width, Screen.height, 0.0f);
Vector3 targetwidth = cam.ScreenToWorldPoint (upperCorner);
float eggwidth = egg.renderer.bounds.extents.x; // error
maxwidth = targetwidth.x - eggwidth;
StartCoroutine (Spawn ());
}
IEnumerator Spawn(){
yield return new WaitForSeconds(2.0f);
while (true) {
Vector3 spawnPosition = new Vector3 (Random.Range(-maxwidth,maxwidth), transform.position.y, 0.0f);
Quaternion spawnRotation = Quaternion.identity;
Instantiate (egg, spawnPosition, spawnRotation);
yield return new WaitForSeconds (Random.Range(1.0f, 2.0f));
}
}

yield return new WaitForSeconds (Random.Range(1.0f, 2.0f));
}
}
}
@umerslilla , You havent defined the renderer property; you need to use GetComponent. declare a Gameobject[] egg; define a public Renderer ren; And in the Start method
ren = egg[0].GetComponent();
