C# WinForm Drawing - how to clear and redraw
- by StoneHeart
Here is screen shot of my game. On the left is my problem, seem "old draw" still existing. On the right is what it should be.

drawing code
Graphics g = e.Graphics;
for (int i = 1; i < 27; i += 1)
{
for (int j = 0; j < 18; j += 1)
{
ZPoint zp = zpoints[i, j];
if (zp != null)
{
g.DrawImage(zp.sprite_index, new Point(zp.x, zp.y));
Image arrow;
if (zp.sprite_index == spr_green_zpoint)
{
arrow = spr_green_arrows[zp.image_index];
}
else if (zp.sprite_index == spr_red_zpoint)
{
arrow = spr_red_arrows[zp.image_index];
}
else
{
arrow = spr_grey_arrows[zp.image_index];
}
g.DrawImage(arrow, new Point(zp.x - 4, zp.y - 4));
}
}
}
if (latest_p1 != -1 && latest_p2 != -1)
{
ZPoint zp = zpoints[latest_p1, latest_p2];
if (zp != null)
{
g.DrawImage(spr_focus, new Point(zp.x - 6, zp.y - 6));
}
}
