Question by Der_Kevin · Nov 05, 2013 at 12:05 AM · errorsemicolon

; expected. Insert a semicolon at the end.

Hey Folks, i have a strange error in my javascript- script:

 var car : Transform;
 var player : Transform;
 var exitPoint : Transform; // Place this empty gameobject next to the driver car door.
 var doorTriggerLeft : Transform;
 //var PlayerCamera : Camera;
 //var CarCamera : Camera; // By default the camera "component" for the car camera should be set to OFF first.
 var isPlayerVisible : boolean;
 
 
 function Update()
 {
 Ray screenRay = Camera.main.ScreenPointToRay(ScreenTouchPosition);
 RaycastHit rayhit;
 if(Physics.Raycast(screenRay, out rayhit)){
     if(rayhit.collider.tag == "CarCube"){
 Debug.Log("Driving");
 // make player invisible and still standing
 player.gameObject.SetActiveRecursively(false);
 player.gameObject.active = false;
 // parent player to Exit Point
 player.parent = exitPoint.transform;
 player.transform.localPosition = Vector3(-1.5,0,0);
 // parent PlayerParent to car
 exitPoint.parent = car.transform;
 exitPoint.transform.localPosition = Vector3(-0.3,1.5,-0.65); //Driverside exit point, adjust accordingly per vehicle.
 // GameObject.Find("VehicleObjectName").GetComponent("DrivingScriptHere").enabled=true;
 GameObject.Find("Car").GetComponent("CarControl").enabled=true; //Enables the script component to operate Vehicle.
 //PlayerCamera.enabled = false; //Disables the playerCamera
 //CarCamera.enabled = true; //Enables the carCamera
 }
 else
 {
 if (Input.GetKeyUp("r")) //Asign any key you want to exit/park vehicle.
 {
 Debug.Log("Walking");
 // make character visible again
 player.gameObject.SetActiveRecursively(true);
 player.gameObject.active = true;
 // unparent player from everything
 player.transform.parent = null;
 // exitPoint.parent = doorTriggerLeft.transform;
 // parent Exit Point to car gameobject
 exitPoint.parent = car.transform;
 // GameObject.Find("VehicleObjectName").GetComponent("DrivingScriptHere").enabled=false;
 GameObject.Find("Car").GetComponent("CarControl").enabled=false; //Disables the script component to park Vehicle.
 //PlayerCamera.enabled = true; //re-enables player camera
 //CarCamera.enabled = false; //disables car camera
 
 }
 }
 }
 
 function OnTriggerEnter(Player : Collider)
 {
 Debug.Log("Trigger Enter");
 isPlayerVisible = true;
 }
 
 function OnTriggerExit(Player : Collider)
 {
 Debug.Log("Trigger Exit");
 isPlayerVisible = false;
 }

unity says: Assets/Standard Assets/Scripts/Car entering & exiting.js(12,4): UCE0001: ';' expected. Insert a semicolon at the end. i have no idea why, could somebody have a quick look over the script and could explain me whats wrong? i think it is in this area:

  function Update()
     {
     Ray screenRay = Camera.main.ScreenPointToRay(ScreenTouchPosition);
     RaycastHit rayhit;
     if(Physics.Raycast(screenRay, out rayhit)){
         if(rayhit.collider.tag == "CarCube"){
     Debug.Log("Driving");

would be great :)

cheers, kevin

Your variables aren't declared correctly:

 //line 12
 Ray screenRay = Camera.main.ScreenPointToRay(ScreenTouchPosition);

JavaScript uses a different syntax:

 var screenRay : Ray = Camera.main.ScreenPointToRay(ScreenTouchPosition);

If you trust the compiler to infer a type, you can omit it:

 //be careful with this! (code can be harder to read, contain errors)
 var screenRay = Camera.main.ScreenPointToRay(ScreenTouchPosition);

Aside from that, you may want to organize your code a bit more carefully. It will be much easier to read and debug.
