Multi Switch Door

Question

hi, im fairly new to unity i currently creating a basic fps project with a simple two way door system i.e a switch that destroys its assigned object im just wondering if theirs any possible way to make it so that the player has to activate multiple switches in order to open the door or destroy it im not looking for coding per say however im just looking to be pushed in the right direction. any help will be greatly appreciated.

You need to create a script (attached to the door) with as many public booleans as there are switches (or, if you rather, an public integer originally set to zero). Each time a switch is activated, change one of the bools to true (or add one to the integer) using the formula [scriptname].[varname] in a separate script. Lastly, use an if statement to check to see that all of the bools are true (or that the integer is equal to the number of switches). Then, either destroy the door ("Destroy(gameObject)") or activate an animation for the door (Animation.Play("/name of animation/")).

Attach this script to a door :

 // Door_Opener_Script

 public var Button1 : Button_Script;
 public var Button2 : Button_Script;

 function Update()
 {
     if (Button1.IsPressed && Button2.IsPressed)
     {
         // Open the Door
         Destroy (gameObject);
     }
 }

On 2 buttons, attach this script to each :

 // Button_Script

 public var IsPressed : boolean = false;
 private var timer : float = 0.0;
 private var timerReset : float = 3.0;

 function OnTriggerEnter( otherCol : Collider )
 {
     IsPressed = true;
     timer = timerReset;
 }

 function Update()
 {
     if (timer < 0)
     {
         IsPressed = false;
         timer = 0;
     }
     else
     {
         timer -= Time.deltaTime;
     }
 }

Then drag-and-drop each button into the Door Inspector (Button1 & Button2)

When anything activates the trigger on a button, the button is set to true. (i have included a timer, so the button starts counting down, then resets to false). The script on the door reads each button script and finds out if IsPressed is set to true. If so, open the door. This is just a quick example and not the best explaination, but let me know if you have any qns on this idea =]

EDIT : I have put a Destroy (gameObject); call where you asked. But you could do many things at this line, play an animation, disable a rigidbody, etc.

Here is the Unity Script Reference for Object.Destroy : http://unity3d.com/support/documentation/ScriptReference/Object.Destroy.html

and OnTriggerEnter : http://unity3d.com/support/documentation/ScriptReference/Collider.OnTriggerEnter.html
