Question by DaveA · Jun 10, 2010 at 07:06 PM · prefabmouseclickgroup

Getting mouse clicks on 'grouped' objects

I have a prefab which contains several objects (say, a plane and 3dtext). I want to detect mouse clicks on this prefab. I made a script with OnMouseDown() function, put it on the Prefab (top leve), I get no clicks. So my questions are:

  1. If there are multiple things in a group, do you have to put the OnMouseDown() on each item in the group? If so, what's the cleanest way to signal that this group was clicked?

  2. Is there a way to have one function intercept mouse clicks on ANY member of a group (what I was hoping).

  3. Am I going about this all wrong, should I be using something else?

My code:

function OnMouseDown() { setDataSpotLabelText("clicked"); }

public function setDataSpotLabelText(s) { t = gameObject.GetComponentInChildren(TextMesh); t.text = s; }

OnMouseDown is per gameobject only

you could do it with raycasting, but i think the easiest way to start is to just have mousedown scripts which send the event to a main script

E.g.

function OnMouseDown()
{
    transform.root.SendMessage("MyOnMouseDown");
}

and in your root script:

function MyOnMouseDown()
{
    //code
}

Thanks, but I'm still not getting the clicks. Dumb question: should I use Javascript or C# or does it matter? Do I need to include/import anything at the top of these scripts?

Ok, I had to add a collider. I didn't want to do that because I don't want the 'avatar' to get stopped by these things. Is that going to be a problem?

Click IsTrigger for the collider, it'll turn off collisions
