Combine two scripts? *simple*

Unity Engine
1

Hello unity people.

I am somewhat lost in a scripting part of a task i’ve been given. Basically its very simple, there is three buttons that control which one of three cameras who are active. I also have a script that makes an object always face a camera. When i change camera i want the “facing” script to change target camera to the active one, in other words make the object always face the active camera

There might be a very simple solution to this, but I have little to no experience in java coding and started my java “career” :wink: yesterday. The attempts i’ve tried so far have turned out fruitless since I’m not to familliar with java structure or coding in general.

If anyone could point me in the right direction in how to complete this function, It would be much appreciated.

Camera button script

var camera1 : Camera; 
var camera2 : Camera; 
var camera3 : Camera;

var cube1 : GameObject;
var cube2 : GameObject;
var background : Texture2D;



function Start() 
{

 
camera1.enabled = true; camera2.enabled = false; camera3.enabled = false;
cube1.renderer.enabled = false; cube2.renderer.enabled = false;


} 



function OnGUI()
{

if (GUI.Button(Rect( 0, 718, 120, 50), "First person"))
{
camera1.enabled = false; camera2.enabled = true; camera3.enabled = false;
}

if (GUI.Button(Rect( 120, 718, 120, 50), "Birdseye"))
{

camera1.enabled = true; camera2.enabled = false; camera3.enabled = false;

}

if (GUI.Button(Rect( 240, 718, 120, 50), "Overview"))
{
camera1.enabled = false; camera2.enabled = false; camera3.enabled = true;
}


GUI.DrawTexture (Rect (0,0, background.width, background.height), background);

      
        
        
 		if (GUI.Button (Rect (830, 61, 70, 30), "", GUIStyle.none))
            {             	
        	cube1.renderer.enabled = true; 
        	}  	
        if (GUI.Button (Rect (900, 61, 70, 30), "", GUIStyle.none))
            {             	
        	cube1.renderer.enabled = false; 
        	}  		
        if (GUI.Button(Rect (830, 91, 70, 30), "", GUIStyle.none))      
        	{
        	cube2.renderer.enabled = true; 
        	}
           if (GUI.Button(Rect (900, 91, 70, 30), "", GUIStyle.none))      
        	{
        	cube2.renderer.enabled = false; 
        	}
        if (GUI.Button(Rect (830, 121, 70, 30), "", GUIStyle.none))      
        	{
        	
        	}
        if (GUI.Button(Rect (900, 121, 70, 30), "", GUIStyle.none))      
        	{
        	
        	}

}

“Facing” script

var target : Camera; 

function Update() 
{
var n = target.transform.position - transform.position;

transform.rotation = Quaternion.LookRotation( n ); 

}

Thanks in advance. :slight_smile:

One way would be to have a global variable which references the active camera. (Although this is not best practice)
Or make a variable on the facing script which takes the control script and simply drop it there in the inspector.
Or use GetComponent.
Or…
