Hi,

How can i get the distance between the player and an enemy?

Thanks

You need position from both. Then you can do vec_dist(...) or vec_lenth(...) - vec_length(...)

this won't work!

you can't calculate the difference between two vectors to the orginin in order to calculate the distance from those two vectors
it's like calculating the difference from city a to city b when comparing the difference from city a to city c and city b to city c

just use vec_dist to calculate the distance between to vectors

Thanks. I try that.

I wrote that in my enemy function as a test

var dist_player_enemy;
you=players[enet_ent_creator(enet_ent_globpointer(me))];
vec_set(player_pos.x,you.x);
vec_set(temporary.x, my.x);
dist_player_enemy=vec_dist (player_pos.x, temporary.x);
if (dist_player_enemy <= 1000) snd_play(alarm_wav, 100, 0);

I have no error, but it dosen't work!
Can you tell me what is wrong?

you are comparing the distance between me and me which is always 0

you should check out this line:
you=players[enet_ent_creator(enet_ent_globpointer(me))];
i think that you want to get the distance to your player in the enemies function
so you need to pass the player to enet_ent_globpointer, not me

Is that correct?

cl_id = enet_get_clientid();
you=players[enet_ent_creator(enet_ent_globpointer(players[cl_id]))];

yes, this should work
also you can calc the distance between you and me directly:
vec_dist(you.x, my.x)

Here is the enemy function as a test
function enemy()
{
cl_id = enet_get_clientid();
you=players[enet_ent_creator(enet_ent_globpointer(players[cl_id]))];
//................................................................
my.emask = ENABLE_SHOOT; // the enemy is sensitive to impact with player's bullets
my.event = enemy_got_shot; // and runs this function when it is hit
if (vec_dist (you.x, my.x) < 1000) snd_play(alarm_wav, 100, 0);
wait (1);
}
I can shoot at the enemy, but it can't see me. What i can do?

you should create a loop for the checking
is it is now, it will be executed only once
