How do I know I clicked on a Gameobject in Unity?

Question

I’m trying to create a game similar to Fruit ninja, but I know little of game programming, I understand code c#, could tell me a method if I clicked on a gameobject?

Answer 1

Add a Collider (any type), nay mark as "Is Trigger", and add this code to your script:

void OnMouseDown()
{
    //clicaram em mim
}

It makes a raycast from the camera point in the click direction.

Answer 2

You should add a Collider to your Gameobject and tag. After adding Collider and tag, in the script linked to your Gameobject you can do the following:

function OnCollisionEnter (c : Collision){
   if(c.gameObject.tag == "meuObjeto") {
     // Faça alguma coisa.
   }
}
