Raycast and SendMessage malfuction

I'm trying to cast a ray that sends a message to a script telling it to run damage functions.

Code (csharp):

1.  var hit : RaycastHit;
2.  
3.     var fwd = transform.TransformDirection(Vector3.forward);
4.  
5.    
6.  
7.     if (Physics.Raycast (rayReference.position, fwd, 100)) {
8.  
9.         print("There is something in front of the object!");
10.  
11.         Debug.DrawLine (transform.position, hit.point);
12.  
13.         hit.collider.gameObject.BroadcastMessage("Hurt4", damage4, SendMessageOptions.DontRequireReceiver);
14.  
15.         }
16.  
17. }

Code (csharp):

1. function Hurt4(damage4 : float){
2. Health -= damage4;
3. print("We're hit!");
4. if(Health <= 0){
5. Death();
6. }
7. }

However, even when the ray registers a hit, the message doesn't get sent or work. I've tried attaching colliders and rigidbodies to ensure that it's hitting, but it just won't work. It constantly says: Object reference not set to an instance of an object

Can anyone give me a reason or solution for this?

 

your not filling the hit variable.

take a look at the docs, you want the overload with the out RaycastHit and put your hit variable in there.

edit: Physics.Raycast(rayReference.position, fwd, hit, 100)

 

THANK YOU!

Man, missing hours of sleep made me overlook that.

 

yep just as a side note, if you avoid using RaycastHit as a member, you would have at least got a warning/error about using a uninitialized variable. Probably best to keep RaycastHit's as local variables when possible.
