man i`m a dunce, i forgot to write function, however the target sprite still is not appearing, here is all the code from the test level
Code:

---

string stars_mdl = "stars.mdl";
string galor_mdl = "galor.mdl";
string excelsior_mdl = "excelsior.mdl";

entity* enemy;

string lockon = "lockon+3.tga";
string cphaser_mdl = "cphaser.mdl";

bmap hempire_tga = "hempire.tga";

function stars();
function c_ship();
function f_ship();
function event_scn();
function got_target();
//function beam_weapons();

function main
{
	///init_radar();
	mouse_map = hempire_tga;
	mouse_mode = 1;
	level_load ("new_beginings.wmb");
	wait(1);
	ent_create (stars_mdl, nullvector, stars);
	ent_create (galor_mdl, vector(0, 0, 0), c_ship);
	ent_create (excelsior_mdl, vector(100,0,0), f_ship);
	///ent_create (excelsior_mdl, vector(200,40,0), f_ship);
	///ent_create (jungle_mdl, vector(1500, 10000, 0), planets);
	///ent_create (clouds_mdl, vector(1500, 10000, 0), clouds);
	///ent_create (jungle_mdl, vector(25000, 10000, 0), planets);
///	ent_create (clouds_mdl, vector(25000, 10000, 0), clouds);
	while (1)
	{
	mouse_pos.x = pointer.x;
	mouse_pos.y = pointer.y;
	wait (5);
	}
}

function c_ship
{
	player = my;	
	my.scale_x = 1.0;	
	my.scale_y = my.scale_x;	
	my.scale_z = my.scale_x;	
	while(1)	
	{		
	if(you == null)		
	{			
	c_scan(player.x, temp, vector(360, 60, 1000),ignore_me+ignore_you);		
	}		
	wait(-0.25);	
	}
}
	
function f_ship
{	
my.scale_x = 2.0;	
my.scale_y = my.scale_x;	
my.scale_z = my.scale_x;	
my.enable_scan = on;	
my.event = event_scn;
}

var enemy_handle; // a global handle we can use for transferring pointersfunction 

function event_scn()
{	
if (event_type == event_scan)		
{		
enemy_handle = handle(me);		
ent_create(lockon, my.x, got_target);	
}
}

function got_target
{	
my.scale_x = 0.1;	
my.scale_y = my.scale_x;	
my.oriented = on;	
my.facing = off;	
you = ptr_for_handle(enemy_handle); // now YOU is the enemy  	
while(you != null)	
{		
vec_set(temp,player.x);		
vec_sub(temp,my.x);		
vec_to_angle(my.pan,temp); // turn the target toward the player		
vec_set(temp,nullvector);		
temp.x = 20; // change this if you need to - the distance in front of the enemy		
vec_rotate(temp,my.pan);		
vec_add(temp,your.x);		
vec_set(my.x,temp);		
wait(1);	
}	
ent_remove(me);
}
