How do I go about moving an object side to side using the mouse.

Question

So basically I have an object in front of the camera and I want the player to be able to move it side to side when holding down a mouse button and dragging. Here is what I have so far. The object does not move at all.

     public bool is_handling;
     public Vector3 mouseReference;
     public Vector3 mouseOffset;
     public Vector3 stickPos;
     private float sensitivity;
 
     public void Start() {
 
         stickPos = Vector3.zero;
         sensitivity = 0.4f;
 
     }
 
     public void Update() {
 
         if(Input.GetMouseButton(1)){
             is_handling = true;
             mouseReference = Input.mousePosition;
                         print (mouseReference);
         } else {
             is_handling = false;
         }
 
         if(is_handling) {
 
             print(Input.mousePosition);
 
             mouseOffset = (Input.mousePosition - mouseReference);
 
             print (mouseOffset);
 
             stickPos.x = (mouseOffset.x) * sensitivity;
 
             transform.Translate(stickPos);
 
             mouseReference = Input.mousePosition;
 
         }
 
     }
 
 
 }

Assuming you actually want t$$anonymous$$s to move in 3-Dimensional space, a simple mouse vector wont translate into the world, so you'll need to raycast. Assuming you want your raycast to pertain to the terrain, t$$anonymous$$s is sort of what you want. If you want an actual raycast that $$anonymous$$ts anyt$$anonymous$$ng, it is a little different, but essentially you need a raycast. The mousePosition only applies to 2D space, and must be raycast through the camera.

        void Update() {
              if (Input.GetMouseButtonDown (1)) {
                  RaycastHit $$anonymous$$t;
                  Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
                  if (goTerrain.GetComponent<Collider>().Raycast (ray, out $$anonymous$$t, Mathf.Infinity)) {
                      transform.position = $$anonymous$$t.point;
                  }
              }
          }
      }

18 sets mouseRef = Input.mousePos; 28 substracts Input.mousePos from mouseRef(Input.mousePos) so 0.

I believe Input.mousePos uses a different coordinate system so you probably need a Camera.main.ScreentoWorldPoint conversion
