I have sent my user out to the browser with Application.OpenURL. And now I want to programatically bring unity back to the foreground.

推荐答案

使用GetActiveWindow获取窗口的句柄，然后再将用户发送出去，然后使用SetForegroundWindow使用该句柄.在使用SetForegroundWindow之前，您可以尝试模拟Alt键，调出一个菜单，以遵守

Use GetActiveWindow to get the window's handle before you send the user away, then use SetForegroundWindow using that handle. Before you use SetForegroundWindow, you can try simulating an Alt keypress to bring up a menu to abide by certain limitations of 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);
}
