I am constantly drawing frames, and I need the form to not flicker. How do I accomplish this?
public partial class Form1 : Form
{
Image[] dude = new Image[3];
static int renderpoint = 0;
int lastimage = 0;
public Form1()
{
dude[1] = new Bitmap(@"snipe1.bmp");
dude[0] = new Bitmap(@"snipe0.bmp");
InitializeComponent();
}
private void Form1_Shown(object sender, EventArgs e)
{
MainLoop();
}
private void MainLoop()
{
double FPS = 10;
long ticks1 = 0;
long ticks2 = 0;
double interval = (double)Stopwatch.Frequency / FPS;
while (true)
{
ticks2 = Stopwatch.GetTimestamp();
if (ticks2 >= ticks1 + interval)
{
ticks1 = Stopwatch.GetTimestamp();
MoveGraphics();
this.Refresh();
}
Thread.Sleep(1);
}
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
Graphics g = e.Graphics;
Rectangle rect = new Rectangle(renderpoint, 0, 100, 100);
Color lowcolor = Color.FromArgb(0, 128, 64);
Color highcolor = Color.FromArgb(0, 128, 64);
ImageAttributes imageAttr = new ImageAttributes();
imageAttr.SetColorKey(lowcolor, highcolor);
if (lastimage == 1)
{
lastimage = 0;
g.DrawImage(dude[1], rect, 0, 0, 100, 100, GraphicsUnit.Pixel, imageAttr);
}
else
{
lastimage = 1;
g.DrawImage(dude[0], rect, 0, 0, 100, 100, GraphicsUnit.Pixel, imageAttr);
}
}
void MoveGraphics()
{
if (renderpoint > 950)
{
renderpoint = 0;
}
else
{
renderpoint += 10;
}
}
}
There's the current code. Suggestions?
Paste this into your Form1 constructor:
Paint
event handlerInvalidate
If you're trying to pull of smooth animation, then may I recommend jumping ship to WPF, OpenGL, or XNA. GDI+ was not designed for animation (the Windows message loop is not a real-time system, so you will always have jittering).
