I'm developing a game (Puzzle) in C # WinForms, to run on a touch screen.
The mapping of ring events to the mouse events already occurs by default, and I did not have to do anything to make that happen. However, the mouse_down only occurs when I move my finger a little, and it does not occur in the precise moment when I touch the screen.
Why is this happening? Should I implement some kind of touch event recognition?
Other problems have arisen, however, such as the overlap and difficulty of distinguishing between touch and mouse events, but the above problem solved the following:
protected override void WndProc(ref Message m)
{
switch (m.Msg)
{
case Win32.WM_POINTERDOWN:
case Win32.WM_POINTERUP:
case Win32.WM_POINTERUPDATE:
case Win32.WM_POINTERCAPTURECHANGED:
break;
default:
base.WndProc(ref m);
return;
}
int pointerID = Win32.GET_POINTER_ID(m.WParam);
Win32.POINTER_INFO pi = new Win32.POINTER_INFO();
if (!Win32.GetPointerInfo(pointerID, ref pi))
{
Win32.CheckLastError();
}
Point pt = PointToClient(pi.PtPixelLocation.ToPoint());
MouseEventArgs me = new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 1, pt.X, pt.Y, 0);
switch (m.Msg)
{
case Win32.WM_POINTERDOWN:
Console.WriteLine("TOCOU" + pt);
(Parent as Jogo).Form1_MouseDown((this as object), me);
break;
case Win32.WM_POINTERUP:
Console.WriteLine("LEVANTOU");
(Parent as Jogo).Form1_MouseUp((this as object), me);
break;
case Win32.WM_POINTERUPDATE:
//Console.WriteLine("UPDATE");
(Parent as Jogo).Form1_MouseMove((this as object), me);
break;
}
}
I used the use of a class "Win32.cs" that can be downloaded here:
I hope it's useful;)
