Hi

I am learning Unity3D so i am absolute beginner in this. I have plane (as ground), on plane i have cube with colider and rigidbody and then i have firstperson controller. I want to go with FPC (firstperson controller) to a cube and click on it with left button on mouse and i expect, that gives me a log in console. Script is attached to cube.

Thanks for help

My script code:

#pragma strict

function OnMouseDown() {
	Debug.Log("Left Click");
}

Use a Raycast using the cursor position from camera to far away:

#pragma strict

var hit : RaycastHit;
//The range of the raycast
var raycastRange : float;
var actualCamera : Camera;

function Update () {
	var ray : Ray = actualCamera.ScreenPointToRay (Input.mousePosition);
 
	//Debug the ray in green
	Debug.DrawRay(ray.origin, ray.direction * raycastRange, Color.green);
 
     
	if(Physics.Raycast (ray, hit, raycastRange)) {
    	if(Input.GetMouseButtonDown(0)){
        	Debug.Log("Touched " + hit.collider.name);
        	//You can use tag for it
        	if(hit.collider.tag == "YourTagHere"){
        		Debug.Log("Touched " + hit.collider.name + " with the " + hit.collider.tag + " tag.");
        	}
    	}
	}
}

Attach this script to camera.
