Question by Bexxth · Oct 28, 2013 at 05:52 AM · transform.position

null reference exception in transform.position?

Hi there! I'm ridiculously new to unity and programming as a whole. I've been doing a tutorial that's worked fantastic right up until this point.

This code is for a ball to drop from the top of the screen, vanish when reaching a certain point at the bottom and then reappears at the top in a different location.

When played the ball just falls continually down and never stops, the consol states: "NullReferenceException: Object reference not set to an instance of an object"

 var enemySpeed: int; 
     
 function Update (){
 
 amtToMove = enemySpeed * Time.deltaTime;
 
 transform.Translate(Vector3.down * amtToMove); 
 
 if(transform.postition.y <= -5){
     
     transform.position.y = 6;
     
     transform.position.x = Random.Range(-6,6);
     
     
     
 }
 
 }

Which line is it? This error applies to references but you have none here apart from transform. Also, line 9 you have a mispell of position and is amtTo$$anonymous$$ove defined somewhere?

Hah! Thanks so much! It was just that misspelling which screwed the whole thing up. I feel a bit stupid now XD

Thank you =D

if(transform.postition.y

//Corrected code

 var enemySpeed: int; 
 private var amtToMove:float;
  
 function Update ()
 { 
     amtToMove = enemySpeed * Time.deltaTime;     
     transform.Translate(Vector3.down * amtToMove); 
  
     if(transform.position.y <= -5)
     {     
         transform.position.y = 6;     
         transform.position.x = Random.Range(-6,6); 
      
     }
  
 }
