c# - Unity C# 相机移动

Question

我目前正在尝试为统一创建一个相机控件(跟随预制件并能够缩放等等......

I am very new to C#

我在使用此脚本时遇到的一个问题是

• 相机缩放到 0,0,0。 (当我需要它停留在当前的 Y 轴上时，我尝试更改 void“Move()”，但向量需要 3 m_.... 的

I also need to write a piece of code that will allow the player to zoom the camera in and out using the scroll wheel... (In "Public Void Update()"...

我一直在浏览指南和视频，但找不到任何可以帮助我解决这个问题的东西..

这是我需要帮助的代码部分:

private void FixedUpdate()
{
    Move();
}

private void Move()
{
    m_DesiredPosition = m_target.position;
    transform.position = Vector3.SmoothDamp(transform.position,
        m_DesiredPosition, ref m_MoveVelocity, m_DampTime);
}

public void Update()
{
    // Get the scroll value of the mouse scroll wheel
    // float scroll = Input.GetAxis("Mouse ScrollWheel");

    // Is the scroll value not 0?

    // Modify the orthographic size by the scroll value
    Camera.main.orthographicSize = 4.8f;
}

Answer 1

要使相机保持在 Y = 0，只需重写 Y:

m_DesiredPosition = m_Target.position;
m_DesiredPosition.Y = 0;
transform.position = Vector3.SmoothDamp(transform.position,
    m_DesiredPosition, ref m_MoveVelocity, m_DampTime);

为了缩放相机，您需要将值添加/减去 orthographicsize 而不是简单地设置它:

// Zoom in
Camera.main.orthographicSize -= 4.8f;
// Zoom out
Camera.main.orthographicSize += 4.8f;
