Question by NormN · May 28, 2014 at 09:31 AM · positionreferencevector

Having problems setting references to GetComponent Script function return values

I am trying to get a vector2 from a pacMan script function so I can find the distance between pacman and an enemy.

I want to subtract pacman's position from an enemy position.

Here is my code from the enemy class:

 private Vector2 pacPos;
 private Vector2 position;
 private GameObject pacman;    
 private PlayerScript pacManScript;
 privateVector2 v;
 
 void Awake ()
     {
         pacman=GameObject.Find("PacMan");
         pacManScript=pacman.GetComponent<PlayerScript>();
     }
 void Start () 
     {
         
         position=new Vector2(1,1);
         pacPos= pacManScript.getPosition();
         v=pacPos-position;
 print("distance between pacman which is "+ pacPos+ " and inky's "+ position+ "is  "   + v);
 
     }

Here it is not working, it does the math wrong when it prints.

When I do this though it works:

 print("distance between pacman which is "+ pacManScript.getPosition()+ " and inky "+ position+ "is  "+ (pacManScript.getPosition()-position));

I was wondering how come this is the case? It seems that my pacPos reference to pacManScript.getPosition() doesent work the way I want it to.

Thank you...I really want to understand GetComponent.

Take Care.

To get the distance between 2 vectors you should use Vector2.Distance(pacPos, position);

When you do v = pacPos - position, you're calculating the direction vector starting from position and ending at pacPos.

Thanks for answering I totally agree with you. However, I am still having problems with the pacPos, it gets assigned a (0,0) vector2 when I do this code. (it should be a differnt vector):

 pacPos= pac$$anonymous$$anScript.getPosition();


I do not know why it gets this incorrect vector.
