pictureBox1.Location = newPoint(x, y);
}
privatevoid timer1_Tick(object sender, EventArgs e)
{
if (imgPosition == Positioning.Right)
{
x += 10;
pictureBox1.Location = newPoint(x, y);
}
elseif (imgPosition == Positioning.Left)
{
x -= 10;
pictureBox1.Location = newPoint(x, y);
}
elseif (imgPosition == Positioning.Up)
{
y -= 10;
pictureBox1.Location = newPoint(x, y);
}
elseif (imgPosition == Positioning.Down)
{
y += 10;
pictureBox1.Location = newPoint(x, y);
}
Invalidate();
}
privatevoid Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.KeyCode == Keys.Left)
{
imgPosition = Positioning.Left;
}
elseif (e.KeyCode == Keys.Right)
{
imgPosition = Positioning.Right;
}
elseif (e.KeyCode == Keys.Up)
{
imgPosition = Positioning.Up;
}
