Script to Exit in play mode-This is my script attached to a cube for movement,i want to make this script exit after 10 seconds in the play mode...any1 pls help??

using UnityEngine;
using System.Collections;

public class PlayerScript : MonoBehaviour {

public float moveSpeed=10;

public void Update()
{
float moveforward=moveSpeed * Time.smoothDeltaTime * Input.GetAxis(“Vertical”);
float moveLeft=moveSpeed * Time.smoothDeltaTime * Input.GetAxis(“Horizontal”);

transform.Translate(Vector3.forward * moveforward);
transform.Translate(Vector3.left * moveLeft);

}

}

You could try using a for loop to fix this

for(i=0;i<=(10*Time.smoothDeltaTime);i++)
{
  //Do your code
}

Hope this helps(and works)

Change your update to this and you should get your desired functionality.
The below code when the game played will run for only 10 seconds.

void update()
{
  if(Time.timeSinceLevelLoad<10f)
  {
  float moveforward=moveSpeed * Time.smoothDeltaTime * Input.GetAxis("Vertical"); 
  float moveLeft=moveSpeed *    Time.smoothDeltaTime * Input.GetAxis("Horizontal");
  transform.Translate(Vector3.forward * moveforward); transform.Translate(Vector3.left * moveLeft);
}
}

If i am wrong in understanding what exactly you are trying to acheive then please leave quesition in the comment and i will try to help you out.
