Hello, after few days I gave up and came to you guys :smiley:

// You can find a reference to Script2 like this, assuming it is attached to some game object in your scene.
var script2 : Script2 = FindObjectOfType(Script2);

// You should always check to make sure script2 was found before trying to use it
if(script2)
{
   if(script2.WOOD >= 50)
   {
      // Do Something
   }
}
else
{
   // You didn't find a Script2 in your scene
}

It did not find that object in a scene. I tried: if(script2) Debug.Log("Found"); else Debug.Log("did not found"); and ofc it printed did not found.

Be sure to replace "Script2" in my example with whatever the name of your script is.

Of Course I did I am not that stupid :) This is really paranormal activity jesus, how that it is not working? Impossible.

Sorry, was not implying you were. :) And you're sure there is a game object with your second script attached in the scene? That should work then... You could put Debug.Log statements in the Start function of you scripts just to verify they are in the scene and active, "Script 1 started", "Script 2 started", etc.

Yes they start I put I can show you the script: Script1 attached to empty game object function Update () { var script2 : Resources = FindObjectOfType(Resources); if(Input.GetButtonDown("Q") && script2.WOOD >= 50) { Instantiate(Structure, transform.position, transform.rotation); } } Resources Script attached to another empty game object: var WOOD : int = 100; function Update () { WoodGUI.text = "Wood: " + WOOD; }
