How can I bind this script into the state of my camera?

Question

Hi!

I'm working on this project where I'm moving a dot around with gravity. I made a C# script to rotate my camera so the player could see all of the dimensions of my levels | Here's a gif of my current state.

The rotation script is here (all of my scripts are in C#)

 using UnityEngine;
 using System.Collections;
 
 public class CameraRotation : MonoBehaviour {
     
 public GameObject targetObject;
 
      private float targetAngle = 0;
      const float rotationAmount = 2.5f;
      public float rDistance = 1.0f;
      public float rSpeed = 1.5f;
 
      public AudioSource source;
      public AudioClip clip;
      private bool isPlayed;
       
       public void Awake() {
           
           source = GetComponent<AudioSource>();
           isPlayed = false;
       }
      
      void Update()
      {
       
 
          if (Input.GetKeyDown(KeyCode.Q))
          {
              targetAngle -= 90.0f;
              source.Play();
          } else if (Input.GetKeyDown(KeyCode.E)) 
          {
              targetAngle += 90.0f;
              source.Play();
          }
       
          if(targetAngle !=0)
          {
              Rotate();
          }
      }
       
      protected void Rotate()
      {
  
          float step = rSpeed * Time.deltaTime;
          float orbitCircumfrance = 2F * rDistance * Mathf.PI;
          float distanceDegrees = (rSpeed / orbitCircumfrance) * 360;
          float distanceRadians = (rSpeed / orbitCircumfrance) * 2 * Mathf.PI;
          
          if (targetAngle>0)
          {
              transform.RotateAround(targetObject.transform.position, Vector3.up, -rotationAmount);
              targetAngle -= rotationAmount;
          }
          else if(targetAngle <0)
          {
              transform.RotateAround(targetObject.transform.position, Vector3.up, rotationAmount);
              targetAngle += rotationAmount;
          }
      }
 }

If you have any idea how C# works, you can see that this makes the camera have 3+1 possible states where the camera rotates around a nullObject that I can place in the middle of my level.

Here is the gravity changing script:

 using UnityEngine;
 using System.Collections;
 
 public class Gravity : MonoBehaviour
 {
     public Vector3[] gravityList = new Vector3[] { };
     void Update()
     {
         if (gravityList.Length < 5) { Debug.Log("gravity List has to be more or exactly at 5"); return; }
         if (Input.GetKeyDown(KeyCode.Space))
         {
             //Restore Gravity for debugging
             Physics.gravity = gravityList[0];
         }
         if (Input.GetKeyDown(KeyCode.W))
         {
             Physics.gravity = gravityList[1];
         }
         if (Input.GetKeyDown(KeyCode.A))
         {
             Physics.gravity = gravityList[2];
         }
         if (Input.GetKeyDown(KeyCode.S))
         {
             Physics.gravity = gravityList[3];
         }
         if (Input.GetKeyDown(KeyCode.D))
         {
             Physics.gravity = gravityList[4];
         }
     }
 }

Now, the question is, how can I bind these scripts in a way that, in whatever camera state, the player-dot will always move to the direction specified? (Press W +9.81 Y) (Press A -9.81 X)

The reason why I'm using gravity instead of just simply moving the player object is that later I will have other objects that should react to the Gravity with the same level of force, just like the player does.

So - what should I do? Code-samples in C# would be amazing. Thanks in advance, people.

wat is the quesstion the rotesin lock to work wat is yor problem ?

i have this code for rotesion bat is js not c#

if you want when he comes in the player

 #pragma strict
 
 var x : float;  
 var y : float; 
 var z : float;
 
 //public var turnSpeed : float = 50f;
 
 function Start () {}
 
 //function OnTriggerStay (other : Collider) { if (other.attachedRigidbody ) other.transform.Rotate(Vector3(x, y, z), -turnSpeed * Time.deltaTime);}
        
 function OnTriggerEnter (other : Collider) {
     if (other.attachedRigidbody)
         other.transform.Rotate(x, y, z); //(Vector3(x, y, z)//, -turnSpeed * Time.deltaTime);
     }

If I understand it correctly, you would like to move relative to the camera's view direction. To do that, first calculate the desired move vector in local space (where y is always up and x is always right), then use transfom.TransformVector(), with the camera's transform and the move vector.
Something like this:

 Vector3 moveDirection = Vector3.zero;
 if (Input.GetKeyDown(KeyCode.W)) { moveDirection += Vector3.up; }
 if (Input.GetKeyDown(KeyCode.A)) { moveDirection -= Vector3.right; }
 // similar for the rest of the inputs
 
 // was there any input?
 if (moveDirection.sqrMagnitude > 0) {
     // if your movement speed is the same in all directions, do this:
     Vector3 moveVector = moveDirection.Normalize() * moveSpeed;
     // otherwise, apply multipliers when handling input
 
     Transform cameraTransform = Camera.main.transform; // or have a reference to it somehow
     Vector3 relativeMoveVector = cameraTransform.TransformVector(moveVector);
 
     // now you can move relative to the camera direction
 }

How can I bind this script into the state of my camera?
