I am working on a space invaders clone using bugs as aliens. Everything works ok but the bug bitmap flickers on the screen.
public void Form1_Load(object sender, EventArgs e)
{
}
int x = 0, y = 0;
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyCode == Keys.Left)
{
x-=5;
if(x<=-350)
{
x = -350;
}
}
if(e.KeyCode == Keys.Right)
{
x+=5;
if(x>=375)
{
x = 375;
}
}
if (e.KeyCode == Keys.Space)
{
if (y <= -530)
{
y = 0;
}
}
}
private void timer1_Tick(object sender, EventArgs e)
{
y -= 5;
Invalidate();
}
protected override void OnPaintBackground(PaintEventArgs e)
{
}
private void Form1_Paint(object sender, PaintEventArgs e)
{
Bitmap bug_one = new Bitmap("bug_one.bmp", true);
Bitmap ship = new Bitmap("ship.bmp", true);
Bitmap bullet = new Bitmap("bullet.bmp", true);
e.Graphics.Clear(this.BackColor);
e.Graphics.DrawImage(ship, 350 + x, 530);
e.Graphics.DrawImage(bullet, 375 + x, 520 + y);
e.Graphics.DrawImage(bug_one, 350, 0);
e.Graphics.Dispose();
}
