here is my code for the enemy:

-----------------------------
action enemy_dummy()
{

enemy = my;

while(1)
{


wait(1);
}
}
-------------------------------

and here is the code for the model:

--------------------------------
action player_machinegun_rotater()
{
my.group = 2;

VECTOR enemypos;

while(1)
{

vec_set(enemypos, enemy.x);
vec_sub(enemypos, my.x);
vec_to_angle(my.pan, enemypos);
my.tilt = 0;

set(my,PASSABLE);

wait(1);
}
}
------------------------------------------------

what am i doing wrong?
