Help With RayCasting

Questions & Answers

Hello,

I have a few objects around my scene, such as a newspaper, a chair and a chocolate bar (tagged correspondently).

What I want to do, is that when the user clicks on either of these objects - it prints to the console the 'tag' or name of the current selected object.

I've been playing around with raycast from camera to mouse position, and I can never get it to work. I have to place a unique script on each of the objects like this:

#pragma strict

function Update(){

var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (collider.Raycast (ray, hit, 100.0) && Input.GetButton("Fire1")) {
    Debug.DrawLine (ray.origin, hit.point);
    print("hitting chair");
    GameControl.ShelfClicked = true;
    }
}

Can I not just have a 'central control' where it works like this:

If chair has been 'raycast' && Fire1 - print 'touched chair'.

If newspaper has been 'raycast' && Fire1 - print 'touched newspaper'.

and so on ... Instead of placing the raycast script into each object?

Hope that makes sense, Thanks!

Give this a shot:

if (Physics.Raycast (ray, hit, 100.0) && Input.GetButtonDown("Fire1"))
{
print ("touched " +hit.collider.gameObject.name);
}

Keep all of your variables just as you have them. I haven't tested it, but should be closer to what you want. Oh, and you don't want the script on every object, just one; the camera or the player or whatever.
