it would be llike this
Code:

---

action player_ship 
{
	var oldpos;
	ship = me;
	my.polygon = on;		
	my.fat = on;
	while(1)
	{	
	vec_set(oldpos,my.x);	
	c_rotate(me,vector(ship_pan*time_step,0,0),glide|ignore_passable|ignore_passents);		
	c_move(me,vector(ship_force*time_step,0,0),nullvector,ignore_passable|ignore_passents|glide);
	
	vec_set(temp,vector(0,0,100));
	vec_rotate(temp,my.pan);
	vec_add(temp,my.x);
	c_trace(my.x,temp,use_polygon);
	if(you == player)
	{
		vec_diff(temp,my.x,oldpos);
		c_move(me,nullvector,temp,ignore_passable|ignore_passents|glide);
		temp = player.pan + ship_pan
		c_rotate(me,vector(temp*time_step,0,0),glide|ignore_passable|ignore_passents);
	}
	wait(1);	
	}	
}
