detecting taps on 3d objects in iOS

Ah I think I understand, so with iOS you need to have just one raycasting function and then detect which object it hit?

Seems a bit confusing because mouseUp raycasting and GUI taps/clicks don't work in this manner.

Anyone be so kind as to post a quick and dirty script they use for this?

heres the final code for those interested. Would still be interested in a bit of code that could be applied to individual objects though, tried out some other things, made sense in code but didn't work. Anyhow:

 var myCamera : Camera;
 var hit : RaycastHit;
 var ray : Ray;
 
 function Update () {
     if(Input.touchCount == 1) {
         var touch: Touch = Input.touches[0];
         ray = myCamera.ScreenPointToRay(Input.touches[0].position);
         if(touch.phase == TouchPhase.Ended && Physics.Raycast(ray.origin, ray.direction,hit)){
             
             switch(hit.collider.name){
                 case "object01":
                     Debug.Log("Object01 tapped");
                     //things
                 break;
                 case "object02":
                     Debug.Log("Object02 tapped");
                     //things
                 break;
             }
         }
         else if (touch.phase == TouchPhase.Ended && !Physics.Raycast(ray.origin, ray.direction,hit)) {
             Debug.Log("tap cancelled");
         }
     }
 }

this only works when the user lifts up their digit, sausage, whatever, without leaving the confines of that objects area, if they change their mind and slide their tap away, it reports the tap as cancelled.

Sure, create a new script named InputManager and fill it out as below. Then create a new Empty Game Object and name it InputManager just so you can find it later on in your scene and add this script to this GameObject.

 private var touchRay : Ray;
 private var touchHit : RaycastHit;
 
 var inputCamera : Camera;
 
 function Awake(){
     if(!inputCamera){
         inputCamera = Camera.main;
         Debug.Log("No camera defined for " + this + " . Main camera is being used now.");
     }
 }
 
 function Update(){
     UpdateTouchInput();
 }
 
 function UpdateTouchInput(){
     if(Input.touchCount == 1){
         var touch : Touch = Input.touches[0];
 
         if(touch.phase == TouchPhase.Began){
             touchRay = inputCamera.ScreenPointToRay(touch.position);
 
             if(Physics.Raycast(touchRay, touchHit)){
                 switch(touchHit.collider.name){
                     case "object1":
                         Debug.Log(touchHit.collider.name + " is hit.");
                     break;
                     case "object2":
                         Debug.Log(touchHit.collider.name + " is hit.");
                     break;
                     case "object3":
                         Debug.Log(touchHit.collider.name + " is hit.");
                     break;
                 }
         }
         }
     }
 }

BTW I haven't tested this so my apologies if there are any typos or syntax errors.

well I finally got it working, here is my final script (badly commented) I hope people can use it.

 var studioBlock : Transform; // blocker behind the door to stop you entering a room
 private var doorObject : GameObject; // the door gameobject (has a collider)
 var doorName = "stdr"; // name of the door gameobject
 private var Telefoon : GameObject;
 var telName = "ipod touch";
 private var hit : RaycastHit;
 private var ray : Ray;
 private var doorOpen : boolean = false;
 
 var inputCamera : Camera;
 
 
 function Start(){
 
 doorObject = GameObject.Find(doorName);
 Telefoon = GameObject.Find(telName);
     
 }
 
 function FixedUpdate (){
     if (Input.touchCount == 1) {
         var touch : Touch = Input.touches[0];
         
         if(touch.phase == TouchPhase.Began){
         print("tap");
         ray = inputCamera.ScreenPointToRay(touch.position);
         
             if(Physics.Raycast(ray, hit)){
                 switch(hit.collider.name){
                     case "stdr":
                         if(!doorOpen){
                             doorObject.transform.animation.Play();// plays the door animation
                             studioBlock.position.y = -100;// removes the room blocker
                             doorOpen = true;
                             //Destroy(this);// destroys the script so you can't spam the door
                         }
                         else
                         {
                             print("door is already open");
                         }
                     break;
                     case "scene phone":
                         print("iphone");
                     break;
                 }
             }
         }
     }
 }

it is attached to a empty game object somewhere in the scene
