C # simulate MSN form jitter
The form jitter is a very interesting thing, let's look at how it works together.
is actually generating random numbers, and then changing the coordinates of the top left corner of the form.
I use a loop to make it, but I can use a timer to control it.
I split the jitter into two kinds of jitter:
1. Generate random numbers, change the upper-left corner of the form coordinates, and then immediately put the form's upper corner coordinates to restore, continue to cycle.
2. Generate random numbers, change the upper-left corner of the form coordinates, after the loop is complete, and then immediately put the form on the upper corner coordinates to restore.
The core code is as follows:
The first kind of jitter
private void button1_Click(object sender, EventArgs e)
{
int recordx = this.Left; //保存原来窗体的左上角的x坐标
int recordy = this.Top; //保存原来窗体的左上角的y坐标
Random random = new Random();
for (int i = 0; i < 100; i++)
{
int x = random.Next(rand);
int y = random.Next(rand);
if (x % 2 == 0)
{
this.Left = this.Left + x;
}
else
{
this.Left = this.Left - x;
}
if (y % 2 == 0)
{
this.Top = this.Top + y;
}
else
{
this.Top = this.Top - y;
}
this.Left = recordx; //还原原始窗体的左上角的x坐标
this.Top = recordy; //还原原始窗体的左上角的y坐标
}
}
The second kind of jitter
private void button2_Click(object sender, EventArgs e)
{
int recordx = this.Left;
int recordy = this.Top;
Random random = new Random();
for (int i = 0; i < 50; i++)
{
int x = random.Next(rand);
int y = random.Next(rand);
if (x % 2 == 0)
{
this.Left = this.Left + x;
}
else
{
this.Left = this.Left - x;
}
if (y % 2 == 0)
{
this.Top = this.Top + y;
}
else
{
this.Top = this.Top - y;
}
System.Threading.Thread.Sleep(1);
}
this.Left = recordx;
this.Top = recordy;
}
