Question by claudiaq16 · Jun 12, 2013 at 03:14 PM · error messageerror-handling

Assets/Scripts/connector_link.js(7,29): BCE0051: Operator '-' cannot be used with a left hand side of type 'UnityEngine.GameObject' and a right hand side of type 'UnityEngine.GameObject'. ERROR HELP!

I have this error..... Assets/Scripts/connector_link.js(7,29): BCE0051: Operator '-' cannot be used with a left hand side of type 'UnityEngine.GameObject' and a right hand side of type 'UnityEngine.GameObject'.

This is the code I have so far....

 #pragma strict
 var v3Start : GameObject;
 var v3End : GameObject;
 
 function Start () {
                                       // Position it
 transform.position = (v3End - v3Start)/2.0f + v3Start; 
  
 var v3T = transform.localScale;      // Scale it
 v3T.y = (v3End - v3Start).magnitude;
 transform.localScale = v3T;
  
                                       // Rotate it
 transform.rotation = Quaternion.FromToRotation(Vector3.up, v3End - v3Start);
 
 
 }
 
 function Update () {
 
 }
 
 function connect(node1, node2){
 //var distance = 
 
 //sphere1.transform.scale.x
 } 


Thanks for any help or suggestions!!! :D

Change your variables to Transform:

 var v3Start : Transform;
 var v3End : Transform;

Instead of v3End you have to use v3End.position. Same for v3Start.

Don't forget to re-assign your objects.

I fixed that but I have another error.

It says Operator '+' cannot be used with a left hand side of type 'UnityEngine.Vector3' and a right hand side type of 'UnityEngine.Transform'.

What does all of this mean? I am pretty new to coding and Unity in general. Thanks!

As @Bunny83 said - Ins$$anonymous$$d of v3End you have to use v3End.position. Same for v3Start.
