Unity3D导出exe窗口参数调整

在Unity3D开发中，有时我们需要对导出的exe窗口参数进行调整，以达到特定的显示效果。下面将详细介绍具体的实现方法。

代码实现

using System;
using System.Runtime.InteropServices;
using UnityEngine;

public class WindowMod : MonoBehaviour
{
// 定义窗口样式枚举
public enum appStyle
{
FullScreen,
WindowedFullScreen,
Windowed,
WindowedWithoutBorder
}

// 定义窗口Z轴深度枚举
public enum zDepth
{
Normal,
Top,
TopMost
}

// 常量定义
private const uint SWP_SHOWWINDOW = 64u;
private const int GWL_STYLE = -16;
private const int WS_BORDER = 1;
private const int GWL_EXSTYLE = -20;
private const int WS_CAPTION = 12582912;
private const int WS_POPUP = 8388608;
private const int SM_CXSCREEN = 0;
private const int SM_CYSCREEN = 1;

// 窗口样式和深度设置
public appStyle AppWindowStyle = appStyle.WindowedFullScreen;
public zDepth ScreenDepth;

// 窗口位置和大小设置
public int windowLeft = 10;
public int windowTop = 10;
public int windowWidth = 800;
public int windowHeight = 600;

private Rect screenPosition;
private IntPtr HWND_TOP = new IntPtr(0);
private IntPtr HWND_TOPMOST = new IntPtr(-1);
private IntPtr HWND_NORMAL = new IntPtr(-2);
private int Xscreen;
private int Yscreen;
private int i;

// 导入Windows API函数
[DllImport("user32.dll")]
private static extern IntPtr GetForegroundWindow();

// 初始化方法
private void Start()
{
// 获取屏幕分辨率

// 根据不同的窗口样式设置分辨率和位置
switch (AppWindowStyle)
{
case appStyle.FullScreen:
Screen.SetResolution(Xscreen, Yscreen, true);
break;
case appStyle.WindowedFullScreen:
Screen.SetResolution(Xscreen - 1, Yscreen - 1, false);
screenPosition = new Rect(0f, 0f, Xscreen - 1, Yscreen - 1);
break;

break;
case appStyle.WindowedWithoutBorder:
Screen.SetResolution(windowWidth, windowHeight, false);
screenPosition = new Rect(windowLeft, windowTop, windowWidth, windowHeight);
break;
}
}

// 更新方法

代码解释

枚举类型

• appStyle：定义了四种窗口样式，分别是全屏、窗口化全屏、普通窗口和无边界窗口。
• zDepth：定义了三种窗口的Z轴深度，分别是正常、置顶和最置顶。

常量定义

定义了一些Windows API所需的常量，如窗口样式标志、系统指标等。

导入Windows API函数

通过DllImport特性导入了一系列Windows API函数，用于操作窗口的位置、样式和显示状态。

Start方法

在游戏开始时，根据AppWindowStyle的值设置窗口的分辨率和位置。

Update方法

在游戏运行过程中，根据AppWindowStyle和ScreenDepth的值设置窗口的样式和位置。为了确保窗口设置生效，该方法会在开始的前5帧内执行。

通过以上代码，我们可以方便地调整Unity3D导出的exe窗口的参数，实现不同的显示效果。
