我试图双倍缓冲来摆脱闪烁器,但重新绘制图像闪烁器。 我需要在新地点的酒吧里用一个周期来重新绘制图像, 这对我有用。 但是当重新绘制非常显著的闪烁器时, 请帮助 。
namespace CockroachRunning
{
public partial class Form1 : Form
{
Random R = new Random();
Semaphore s1 = new Semaphore(2, 4);
Bitmap cockroachBmp = new Bitmap(Properties.Resources.cockroach, new Size(55, 50));
List<Point> cockroaches = new List<Point>();
public Form1()
{
InitializeComponent();
this.DoubleBuffered = true;
cockroaches.Add(new Point(18,13));
Thread t1 = new Thread(Up);
t1.Start();
}
public void Up()
{
while (true)
{
s1.WaitOne();
int distance = R.Next(1, 6);
for (int i = 0; i < distance; i++)
{
if (cockroaches[0].Y - 1 > -1)
{
cockroaches[0] = new Point(cockroaches[0].X, cockroaches[0].Y - 1);
panel1.Invalidate();
}
}
s1.Release();
Thread.Sleep(100);
}
}
private void panel1_Paint(object sender, PaintEventArgs e)
{
Image i = new Bitmap(panel1.ClientRectangle.Width, panel1.ClientRectangle.Height);
Graphics g = Graphics.FromImage(i);
Graphics displayGraphics = e.Graphics;
g.DrawImage(cockroachBmp, cockroaches[0]);
displayGraphics.DrawImage(i, panel1.ClientRectangle);
}
}
}
