Problem with physics.raycast

I want to know if "wall" is intersecting line between A and B objects
This code is attached to object A and target object is B
It works but in a strange way.

If A and B objects position are like in first picture it works but, if I move object A like in second picture,
raycast does not collide anymore. Same thing happens if I move object A to opposite side

Thanks and sorry for my bad English

Code (CSharp):

1.     public GameObject target;
2.     public RaycastHit hit;
3.  
4.     void Update () {
5.             if(Physics.Raycast(transform.position, target.transform.position, out hit)){
6.                 Debug.DrawLine(transform.position, target.transform.position);
7.                 if(hit.collider.gameObject.tag == "wall"){
8.                     print ("hit " + hit.transform.tag);
9.                 }
10.             }
11.         }

 

The second argument in Raycast is a direction, not a position. Try this :

Code (CSharp):

1. if(Physics.Raycast(transform.position, transform.position- target.transform.position, out hit))
2. {
3. //do stuff
4. }

 

thanks for answer

if you or someone can help me

thanks

 

DoomSamurai almost got it, try writing the second parameter like this :

Code (CSharp):

1. target.transform.position - transform.position

Well it happens from time to time, I'll do the same mistakes from time to time .
