我试图让相机在第一人称游戏中以相同的方式移动，但它没有移动为什么

本文关键字：移动 方式 为什么 相机 第一人称 游戏 | 更新日期: 2023-09-27 18:36:34

这是我的Game1.cs代码，我标记了相机移动代码部分的区域：在我的 Game1 中添加了相机代码.cs我在这里使用了 riemers 教程相机代码：

http://www.riemers.net/eng/Tutorials/XNA/Csharp/Series4/Mouse_camera.php

我还尝试了user31911底部的代码，但相同的结果是相机指针/光标在中间跳舞/摇晃并且没有响应。

我尝试使用 Camera 类使用鼠标移动相机。

在构造函数中，我有这一行：

viewMatrix = Matrix.CreateLookAt(cameraPosition, cameraFinalTarget, cameraRotatedUpVector);

如果我稍后在代码中使用此行来分配 viewMatrix 变量，那么我根本看不到地形。

最大的主要问题是鼠标根本没有响应，我得到的是鼠标指针在中间跳舞/摇晃。唯一响应的是我的ProcessInput方法，我做的键正在工作，但是方法ProcessInputCamera的键和鼠标在移动相机时没有恢复，鼠标光标在中间摇晃/跳舞。

我不知道为什么会这样。

但是鼠标没有移动相机。

请编辑您的问题！有很多不必要的信息...

{

int centerY = device.Viewport.Height / 2;

oldY = centerY; 
} 
private void UpdateMatrices() //standart camera things
{ 
rotation = Matrix.CreateRotationY(yaw) * Matrix.CreateRotationX(pitch); 
Vector3 transformedReference = Vector3.Transform(new Vector3(0, 0, -1), rotation); 
Vector3 lookAt = cameraPosition + transformedReference; 
view = Matrix.CreateLookAt(cameraPosition, lookAt, Vector3.Up); 
} 
public void move(Vector3 v) // is the self programmed method to let you move
{ 
Matrix yRotation = Matrix.CreateRotationY(yaw); 
v = Vector3.Transform(v, yRotation); 
cameraPosition += v; 
} 
}

这是相当标准的，但很好。在大多数情况下，此类是相机及其配置所需的全部内容。重写/修复它，就像您需要它一样...

Tipp：你也可以考虑一个弧球凸轮。
