Lock/Slow camera rotation when opening door

Unity Engine
1

Hi guys,

I am stuck on a mechanism for opening doors. I have implemented a script to open doors Amnesia-Style.
i.e, Hold your left mouse button and drag the door to open it or close it so you have full control of it.

One detail is pissing me off. When I rotate camera to open/close the door I want the camera to stop rotate or eventually just slow down the rotation and maybe focus more on the door. I will be happy with just lock the camera that sounds easier to do to me. I have tried but obviously the movement of the door is affected by the rotation of the camera. so I will need something that “break” this dependency so the door can be rotated without using camera rotation.

Any ideas ?

This code represent the mechanism to open/close the door.

private IEnumerator DragObject(float distance)
        {
            var oldDrag = m_SpringJoint.connectedBody.drag;
            var oldAngularDrag = m_SpringJoint.connectedBody.angularDrag;
            m_SpringJoint.connectedBody.drag = k_Drag;
            m_SpringJoint.connectedBody.angularDrag = k_AngularDrag;
            var mainCamera = FindCamera();
            while (Input.GetMouseButton(0))
            {
                var ray = mainCamera.ScreenPointToRay(Input.mousePosition);
                m_SpringJoint.transform.position = ray.GetPoint(distance);
           
            yield return null;
            }
            if (m_SpringJoint.connectedBody)
            {
                m_SpringJoint.connectedBody.drag = oldDrag;
                m_SpringJoint.connectedBody.angularDrag = oldAngularDrag;
                m_SpringJoint.connectedBody = null;
            }
        }

This one is main part of the Player camera movement script

if(enableCameraMovement && !controllerPauseState){
            float mouseYInput = 0;
            float mouseXInput = 0;
            float camFOV = playerCamera.fieldOfView;
            if (cameraInputMethod == CameraInputMethod.Traditional || cameraInputMethod == CameraInputMethod.TraditionalWithConstraints){
                    mouseYInput = mouseInputInversion == InvertMouseInput.None || mouseInputInversion == InvertMouseInput.X ? Input.GetAxis("Mouse Y") : -Input.GetAxis("Mouse Y");
                    mouseXInput = mouseInputInversion == InvertMouseInput.None || mouseInputInversion == InvertMouseInput.Y ? Input.GetAxis("Mouse X") : -Input.GetAxis("Mouse X");
               
                mouseYInput = mouseInputInversion == InvertMouseInput.None || mouseInputInversion == InvertMouseInput.X ? Input.GetAxis("Mouse Y") : -Input.GetAxis("Mouse Y");
                mouseXInput = mouseInputInversion == InvertMouseInput.None || mouseInputInversion == InvertMouseInput.Y ? Input.GetAxis("Mouse X") : -Input.GetAxis("Mouse X");
            }
            else{
                mouseXInput= Input.GetAxis("Horizontal") * (mouseInputInversion == InvertMouseInput.None || mouseInputInversion == InvertMouseInput.Y ? 1 : -1);
            }            if(targetAngles.y > 180) { targetAngles.y -= 360; followAngles.y -= 360; } else if(targetAngles.y < -180) { targetAngles.y += 360; followAngles.y += 360; }
            if(targetAngles.x > 180) { targetAngles.x -= 360; followAngles.x -= 360; } else if(targetAngles.x < -180) { targetAngles.x += 360; followAngles.x += 360; }
            targetAngles.y += mouseXInput * (mouseSensitivity - ((baseCamFOV-camFOV)*fOVToMouseSensitivity)/6f);
            if (cameraInputMethod == CameraInputMethod.Traditional){ targetAngles.x += mouseYInput * (mouseSensitivity - ((baseCamFOV - camFOV) * fOVToMouseSensitivity) / 6f);}
            else {targetAngles.x = 0f;}
            targetAngles.x = Mathf.Clamp(targetAngles.x, -0.5f * verticalRotationRange, 0.5f * verticalRotationRange);
            followAngles = Vector3.SmoothDamp(followAngles, targetAngles, ref followVelocity, (cameraSmoothing)/100);
           
            playerCamera.transform.localRotation = Quaternion.Euler(-followAngles.x + originalRotation.x,0,0);
            transform.localRotation =  Quaternion.Euler(0, followAngles.y+originalRotation.y, 0);
        }

Thanks

The way I would do this is just the following:

  • When you grab the door handle disable the component on the player that controls looking around.
  • Enable a component on the door (or the player) that controls the door movement.
  • When the player is done manipulating the door, disable the door controller and re-enable the player look component

It’s that simple if your components are nicely separated out.
