Question

当鼠标越过边界时，我正在为屏幕平移创建代码。代码有效，但无论浮动速度值如何，它都以相同的速度滚动（我已经尝试了很大的值，例如3000000只是为了检查），从我在线检查我正确使用Time.deltaTime，所以我不知道发生了什么。

public static bool isOnMap = true;
public GameObject CameraObject;
public int Boundary = 50; // distance from edge scrolling starts
public float speed = 1f;
private int theScreenWidth;
private int theScreenHeight;
public static float MapWidth;
public static float MapHeight;

public float Velocity ()
{
    float velocity;
    velocity = speed * Time.smoothDeltaTime;
    Debug.Log(velocity);
    return velocity;
}

void Start()
{
    theScreenWidth = Screen.width;
    theScreenHeight = Screen.height;

}
void Update()
{   
    //mouse
    #region
    if (isOnMap && Input.mousePosition.x > theScreenWidth - Boundary)
    {
        if (transform.position.x >= MapWidth)
        {
            return;
        }
        else
        {
            transform.position = new Vector3(transform.position.x + Velocity(), transform.position.y, transform.position.z);
        }
    }
    if (isOnMap && Input.mousePosition.x < 0 + Boundary)
    {
        if (transform.position.x <= 5)
        {
            return;
        }
        else
        {
            transform.position = new Vector3(transform.position.x - Velocity(), transform.position.y, transform.position.z);
        }
    }
    if (isOnMap && Input.mousePosition.y > theScreenHeight - Boundary)
    {
        if (transform.position.y >= MapHeight + 5)
        {
            return;
        }
        else
        {
            transform.position = new Vector3(transform.position.x, transform.position.y + Velocity(), transform.position.z);
        }
    }
    if (isOnMap && Input.mousePosition.y < 0 + Boundary)
    {
        if (transform.position.y <= 0)
        {
            return;
        }
        else
        {
            transform.position = new Vector3(transform.position.x, transform.position.y - Velocity(), transform.position.z);
        }
    }
  }

Answer 1

如下更改。同时更改speed 1以更改总体速度。

public float Velocity ()
{
    return speed * Time.deltaTime;
}

变量* Time.deltaTime总是只返回Time.deltaTime
