c# - 有什么方法可以将 Unity3d 带到前台？

Question

我已使用 Application.OpenURL 将我的用户发送到浏览器。现在我想以编程方式将统一带回前台。

有没有不用插件的方法呢？

谢谢。

在将用户送走之前使用 GetActiveWindow 获取窗口的句柄，然后使用该句柄使用 SetForegroundWindow。在使用 SetForegroundWindow 之前，您可以 try simulating an Alt keypress调出要遵守的菜单certain limitations SetForegroundWindow:

private IntPtr unityWindow;

[DllImport("user32.dll")] 
static extern IntPtr GetActiveWindow();

[DllImport("user32.dll")] 
static extern bool SetForegroundWindow(IntPtr hWnd); 

[DllImport("user32.dll")]
static extern void keybd_event(byte bVk, byte bScan, uint dwFlags, int dwExtraInfo);

const int ALT = 0xA4;
const int EXTENDEDKEY = 0x1;
const int KEYUP = 0x2;

private void SendUser() 
{
    unityWindow = GetActiveWindow();

    Application.OpenURL("http://example.com");

    StartCoroutine(RefocusWindow(30f));
}


private IEnumerator RefocusWindow(float waitSeconds) {
    // wait for new window to appear
    yield return new WaitWhile(() => unityWindow == GetActiveWindow());

    yield return new WaitForSeconds(waitSeconds);

    // Simulate alt press
    keybd_event((byte)ALT, 0x45, EXTENDEDKEY | 0, 0);

    // Simulate alt release
    keybd_event((byte)ALT, 0x45, EXTENDEDKEY | KEYUP, 0);

    SetForegroundWindow(unityWindow);
}
