Cursors, Point, Differences. C# in WinForms -


i have been working on 1 bit of code week , far have had no answer work around error coming across. error on line var diff = cursor.position - playerpoint;, error occurs because cannot use (-) operand between windows.point , drawing.point coding convert seems convert expression involved in.

the commented out code different attempt @ same method produces same error. got on this?

private void tmrmoving_tick(object sender, object value, type targettype,             object parameter, cultureinfo culture, eventargs e)         {             system.drawing.point dp = (system.drawing.point)value;             var playerpoint = new system.windows.point(dp.x, dp.y);              var curspoint = new system.windows.point(cursor.position.x, cursor.position.y);            // var playerpoint = new system.windows.point(player.location.x, player.location.y);             var diff = cursor.position - playerpoint;             var speed = math.sqrt(diff.x * diff.x + diff.y * diff.y);             if (speed > 10)             {                 diff.x /= speed / 10;                 diff.y /= speed / 10;             }             player.location += new system.drawing.point((int)diff.x, (int)diff.y);         } 

edit if method isn't seen through above code there may resolve in below:

private void tmrmoving_tick(object sender, object value, type targettype,         object parameter, cultureinfo culture, eventargs e)     {          var curspoint = new system.windows.point(cursor.position.x, cursor.position.y);         var playerpoint = new system.windows.point(player.location.x, player.location.y);         var diff = cursor.position - playerpoint;         var speed = math.sqrt(diff.x * diff.x + diff.y * diff.y);         if (speed > 10)         {             diff.x /= speed / 10;             diff.y /= speed / 10;         }         player.location += new system.drawing.point((int)diff.x, (int)diff.y);     } 

since cursor windows forms / gdi+ class, , use of system.windows.point indicates use wpf have problem. classes not inter-exchangeable.

if using wpf: instead of cursor.position, can use mouse.getposition(application.current.mainwindow); pointed out here.

if using wf: use system.drawing.point way, not system.windows.point.

still, subtracting points isn't possible. should write yourself, or better, construct new point , math in constructor call.
