相机投球问题统一

Question

我有这个代码，它在某些字段上给我这个错误。谁能给我一个解决方案吗？

Assets \ Scripts \ CameraController.cs（46,17）：错误CS0120：非静态字段，方法或属性'Camera.isOrthoGraphic'需要对象引用

Assets \ Scripts \ CameraController.cs（49,17）：错误CS0120：非静态字段，方法或属性'Camera.orthographicSize'需要对象引用

Assets \ Scripts \ CameraController.cs（57,17）：错误CS0120：非静态字段，方法或属性'Camera.fieldOfView'需要对象引用

码：

public float perspectiveZoomSpeed = 0.5f; //透视模式下视野的变化率。 public float orthoZoomSpeed = 0.5f; //正交模式下正交尺寸的变化率。

// Update is called once per frame
void Update () {

    if (GameManager.GameIsOver)
    {
        this.enabled = false;
        return;
    }

    // If there are two touches on the device...
    if (Input.touchCount == 2)
    {
        // Store both touches.
        Touch touchZero = Input.GetTouch(0);
        Touch touchOne = Input.GetTouch(1);

        // Find the position in the previous frame of each touch.
        Vector2 touchZeroPrevPos = touchZero.position - touchZero.deltaPosition;
        Vector2 touchOnePrevPos = touchOne.position - touchOne.deltaPosition;

        // Find the magnitude of the vector (the distance) between the touches in each frame.
        float prevTouchDeltaMag = (touchZeroPrevPos - touchOnePrevPos).magnitude;
        float touchDeltaMag = (touchZero.position - touchOne.position).magnitude;

        // Find the difference in the distances between each frame.
        float deltaMagnitudeDiff = prevTouchDeltaMag - touchDeltaMag;

        // If the camera is orthographic...
        if (**Camera.isOrthoGraphic**)
        {
            // ... change the orthographic size based on the change in distance between the touches.
            **Camera.orthographicSize** += deltaMagnitudeDiff * orthoZoomSpeed;

            // Make sure the orthographic size never drops below zero.
            **Camera.orthographicSize** = Mathf.Max(**Camera.orthographicSize**, 0.1f);
        }
        else
        {
            // Otherwise change the field of view based on the change in distance between the touches.
            **Camera.fieldOfView** += deltaMagnitudeDiff * perspectiveZoomSpeed;

            // Clamp the field of view to make sure it's between 0 and 180.
            **Camera.fieldOfView** = Mathf.Clamp(**Camera.fieldOfView**, 0.1f, 179.9f);
        }
    }
}

Answer 1

您需要让主摄像头实例添加字段

public Camera cam;

并访问cam.IsOrtographic

确保将编辑器中的链接链接到相机

Answer 2

只需将Camera.xxxxx替换为场景中自己的实例摄像头，例如：

• Camera.main.isOrthoGraphic
• Camera.main.orthographicSize
• Camera.main.fieldOfView。
