Using hslider the bmp is moving horizantally, but how can i move it in circular or semicircular motion with respect to time.

code:
-----

panel speed_factor
{
bmap = slider_pcx;
layer = 20;
pos_x = 10;
pos_y = 25;
hslider = 10, -12, 200, cursor_pcx, 0, 60, temp1;
flags = d3d, overlay, refresh;
}

////////////////////////////////////////////////////////////////

function init_timedemo()
{
speed_factor.visible = on;
WHILE (1)
{
IF (seconds > 0) // limit the health decrease
{

temp1 = seconds - 1 ;

}
else
{
time_txt.visible = off;
wait(3);
EXIT;
}

WAIT (1);
}

}

Maybe you've to try panel.angle and panel.center_x/panel.center_y.

while(1)
{
my_panel.angle+=5*time_step;
my_panel.center_x = my_panel.size_x * 0.5;
my_panel.center_y = my_panel.size_y * 0.5;
wait(1);
}

thanks,
but my problem is not yet solved.
i want it to move on a circle(circular movement), but it is paning(rotating) in the same position.

You should change the center_x and center_y parameters, this is the rotation center.

Code:

---

var panel_radius[2] = 10,10; //if both values are equal: circle movement
var panel_pos[2]; //middle point of the circle on which the panel moves
var radius_speed = 10; //the speed of the movement
var status_panel;
var panel_angle;

panel my_panel
{
  bmap = cursor_pcx;
  layer = 20;
  flags = d3d,overlay;
}

function move_panel()
{
  while(status_panel)
  {
    my_panel.pos_x = panel_radius.x * cos(panel_angle);
    my_panel.pos_y = panel_radius.y * sin(panel_angle);
    
    panel_angle += radius_speed * time_step;
    wait(1);
  }
}

function stop_panel()
{
  status_panel = 0;
}

function init_panel()
{
  panel_pos.x = screen_size.x / 2;
  panel_pos.y = screen_size.y / 2;
  status_panel = 1;
  move_panel();
}

Hope this helps a bit.
