Make winform run away from the mouse.
- by JACK IN THE CRACK
Okay so I'm trying to make a little gag program that will "run away" from the mouse.
So, to get the mouse coordinates for the whole screen and not just the form control I had to create a little helper:
static class MouseHelper
{
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
internal static extern bool GetCursorPos(ref Point pt);
public static Point GetPosition()
{
Point w32Mouse = new Point();
GetCursorPos(ref w32Mouse);
return w32Mouse;
}
}
Now I thought I was going to use the MouseMove event... but that doesn't work for outside the form control either so I have an auto-enabled timer on a 10ms loop called timerMouseMove.
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private bool CollisionCheck()
{
Point win32Mouse = MouseHelper.GetPosition();
if (win32Mouse.X <= Location.X || win32Mouse.X >= (Location.X + Width))
return false;
if (win32Mouse.Y <= Location.Y || win32Mouse.Y >= (Location.Y + Height))
return false;
return true;
}
private void timerMouseMove_Tick(object sender, EventArgs e)
{
if (CollisionCheck())
Location = new Point(Location.X + 1, Location.Y + 1);
}
}
So this works out nicely, at least I have the collision checking working and whatnot. But now, how should I go about figuring which side of the form the mouse has collided with, so that I can update its location to move in the opposite direction the mouse collides with it? And such halp
