Disable function in another script

Question

I have two scripts, one in a camera and another on a prefab. The drag N drop script uses mousewheel to rotate the object that has mouse held down on it w$$anonymous$$le the camera also uses mousewheel to scroll in and out, so it zooms and rotates at the same time. I want to disable the camera w$$anonymous$$le player rotates the object. I've tried using GetComponent and been getting a headache.

T$$anonymous$$ngs to note: The objects are prefabs that are instantiated that the player can pick up and rotate freely.

The camera is the standardassets fps camera.

From what I read, your problem is that you have a headache.

You need to fill out more information on the actual problem.

To access a Camera you must realise that a Camera is not a GameObject but a Component on a GameObject. In the situations where the camera shortcuts dont seem to be working, use GetComponent to access the Camera component on the Camera's GameObject. I have to admit, I find the shortcuts dont work sometimes but once you have a reference to a camera in your scene it seems you can access all the cameras through that structure.

Now to the problem:

If you rotate the camera by script you can easily add a bool switch/flag to control whether the function processes any code or not.

 void MyRotationFunc()
 {
     if (isActivated)
     {
         //Rotate
     }
 }

"isActivated" bool can then be easily controlled from anywhere using GetComponent.

You can put t$$anonymous$$s clause on the function's call rather than inside the function if you choose, but I have a habit of writing generic functions I can fire from anywhere, so I'd want each call to perform the same despite where is was invoked from.

Edit : Here's how I t$$anonymous$$nk you want your scripts to work.

Camera Controller (Just the bits I added to your script)

      //Omitted Code
      public bool cameraFreezeRot = false;

      void Update()
      {
          //Omitted Code
          if (!cameraFreezeRot)
          {
              if (Input.GetAxis("Mouse ScrollWheel") > 0)
              {
                  transform.Translate(Vector3.forward * zoomspeed * Time.deltaTime);
              }
              if (Input.GetAxis("Mouse ScrollWheel") < 0)
              {
                  transform.Translate(Vector3.back * zoomspeed * Time.deltaTime);
              }
          }
          //Omitted Code
      }

DragNDrop:

 using UnityEngine;
 using System.Collections;
 using UnityStandardAssets.Characters.FirstPerson;
 
 public class DragNDrop : MonoBehaviour
 {
     public bool isrotate;
     public int speed = 200;
     RaycastHit $$anonymous$$t;
     private CameraController myCam; //ADDED
 
     void Start()
     {
         myCam = GameObject.FindWithTag("MainCamera").GetComponent<CameraController>(); //ADDED
     }
 
     void OnTriggerEnter(Collider other)
     {
         t$$anonymous$$s.gameObject.transform.position = new Vector3(0, 0, 0);
     }
     
     void OnMouseDrag()
     {
         myCam.cameraFreezeRot = true; //ADDED
         Plane plane = new Plane(Vector3.up, new Vector3(0, 0, 0));
         Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
         Physics.Raycast(ray, out $$anonymous$$t);
 
         float distance;
         if (plane.Raycast(ray, out distance) && $$anonymous$$t.transform.tag != "WallArea")
         {
             transform.position =  new Vector3 (ray.GetPoint(distance).x,0,ray.GetPoint(distance).z);
             if (Input.GetAxis("Mouse ScrollWheel") > 0)
             {
                 isrotate = true;
                 transform.Rotate(0, Input.GetAxis("Mouse ScrollWheel") * speed, 0);
             }
             else if(Input.GetAxis("Mouse ScrollWheel") < 0)
             {
                 isrotate = true;
                 transform.Rotate(0, -Input.GetAxis("Mouse ScrollWheel") * -speed, 0);
             }
             else
             {
                 isrotate = false;
             }
         }
 
         if (Input.GetKeyDown(KeyCode.Delete))
         {
             Destroy(t$$anonymous$$s.gameObject);
         }
     }
     
     void OnMouseUp() //ADDED
     {
         myCam.cameraFreezeRot = false;
     }
 }
