统一拖动 360 度全景摄像机

Question

我在Unity的360 Image工作。下面的代码工作正常，但我必须用双指拖动相机。

如何使用单次触摸四处走动？我还想在移动时单击对象。

public class DragCamera : MonoBehaviour {
        #if UNITY_EDITOR
        bool isDragging = false;
        float startMouseX;
        float startMouseY;
        Camera cam;
        void Start () {
            cam = GetComponent<Camera>();
        }
        void Update () {
            if(Input.GetMouseButtonDown(1) && !isDragging )
            {                
                isDragging = true;
                // save the mouse starting position
                startMouseX = Input.mousePosition.x;
                startMouseY = Input.mousePosition.y;
            }
            else if(Input.GetMouseButtonUp(1) && isDragging)
            {                
                // set the flag to false
                isDragging = false;
            }
        }
        void LateUpdate()
        {
            if(isDragging)
            {
                float endMouseX = Input.mousePosition.x;
                float endMouseY = Input.mousePosition.y;
                //Difference (in screen coordinates)
                float diffX = endMouseX - startMouseX;
                float diffY = endMouseY - startMouseY;

                float newCenterX = Screen.width / 2 + diffX;
                float newCenterY = Screen.height / 2 + diffY;
                Vector3 LookHerePoint = cam.ScreenToWorldPoint(new Vector3(newCenterX, newCenterY, cam.nearClipPlane));
                //Make our camera look at the "LookHerePoint"
                transform.LookAt(LookHerePoint);
                //starting position for the next call
                startMouseX = endMouseX;
                startMouseY = endMouseY;
            }
        }
        #endif
    }
}

您需要向应用添加真正的触摸支持。

我不知道你是否真的理解你得到的剧本。

一团糟。我会帮你解决的。

public class DragCamera : MonoBehaviour {
        #if UNITY_EDITOR
        bool isDragging = false;
        float startMouseX;
        float startMouseY;
        Camera cam;
        void Start () {
            cam = GetComponent<Camera>();
        }
        void Update () {
            if(Input.touchCount > 0 && !isDragging )
            {                
                isDragging = true;
                // save the mouse starting position
                startMouseX = Input.GetTouch(0).position.x;
                startMouseY = Input.GetTouch(0).position.y;
            }
            else if(Input.touchCount == 0 && isDragging)
            {                
                // set the flag to false
                isDragging = false;
            }
        }
        void LateUpdate()
        {
            if(isDragging)
            {
                float endMouseX = Input.GetTouch(0).position.x;
                float endMouseY = Input.GetTouch(0).position.y;
                //Difference (in screen coordinates)
                float diffX = endMouseX - startMouseX;
                float diffY = endMouseY - startMouseY;

                float newCenterX = Screen.width / 2 + diffX;
                float newCenterY = Screen.height / 2 + diffY;
                Vector3 LookHerePoint = cam.ScreenToWorldPoint(new Vector3(newCenterX, newCenterY, cam.nearClipPlane));
                //Make our camera look at the "LookHerePoint"
                transform.LookAt(LookHerePoint);
                //starting position for the next call
                startMouseX = endMouseX;
                startMouseY = endMouseY;
            }
        }
        #endif
    }
}

请注意，这段代码很糟糕，很混乱，建议不要使用它。它是未经测试的，这意味着它可能会也可能不会起作用。

我只是来修复你得到的东西。
