#ActualTheSasquatch

Posted 20 January 2013 - 10:51 PM

I have had the same problem in the past. I just suspended my game loop when I opened a modal dialog.

 

This is my first winform project, and I'm having trouble figuring out how to do that. I tried having the save/load menu items' on-click methods disable the pirctureBox and enable it again when the dialogue is closed, but apparently, contrary to the method name, saveFileDialog1_FileOk runs its code before the ok button is clicked, re-enabling the pictureBox immediately.

 

I read a post on msdn suggesting the problem is using the XNA input methods rather than the generic windows ones, which apparently check for this kind of thing already. I've been working on it, but c#/winform input handling is completely new to me and it's slow going. Seems completely different from the java application programming I've done in the past.

 

UPDATE: Fixed it.

 

I reworked the code to use the Windows.Forms mouse event methods rather than XNA's input methods, and that solved the click-through problem. Just had to use PointToClient and set up offset values (i.e., int offset = myPictureBox.Location.X) to subtract from my mouse coordinates.

Here's the relevant code, for anyone who stumbles upon this problem in the future:

//constructor
public MapEditor() 
{ 
    InitializeComponent(); 

    this.pctSurface.MouseDown += new MouseEventHandler(pctSurface_Click); 

    pctSurface_xOffset = pctSurface.Location.X; //private instance variables 
    pctSurface_yOffset = pctSurface.Location.Y; 
} 
//on click 
private void pctSurface_Click(object sender, EventArgs e) 
{ 
    //convert from screen coordinates to game world coordinates
    Vector2 mouseLoc = Camera.ScreenToWorld( new Vector2(
                                            PointToClient(MousePosition).X - pctSurface_xOffset, 
                                            PointToClient(MousePosition).Y - pctSurface_yOffset)); 
    switch (MouseButtons)
     { 
        case System.Windows.Forms.MouseButtons.Left: 
        //whatever you need left clicks to do 
        break;
        //etc
