hello,

i'm searching a piece of code that returns an array of player indexes in a certain radius around a player

i know find_ent_in_sphere should be capable of doing that, but can anyone give me an example ?

the player "id" is the start entity, so the search should start around him and it would have to return an array of players in a radius of 100


or should i use a traceline around the player's body to find the closest player-entity?

Something like this?:

public test(id){
   new Float:vOrigin[3]; //get my origin
   entity_get_vector( id, EV_VEC_origin, vOrigin ); 
   new Radius = 100.0
  while((ent = find_ent_in_sphere(id, vOrigin, Radius)) != 0)
    {
        if(!is_user_alive(ent) || ent == id)
        {
            return 0
        }
        else
        {
 
            //Do the stuff if a player was found
            explosion(ent)     // create an explosion on each found entity.
        }
    }
}
public explosion (id){ 
   new startloc[3] 
   get_user_origin(id,startloc)
   message_begin( MSG_ALL, get_user_msgid("Explosion"), {0,0,0} ,id); 
   write_coord(startloc[0])
   write_coord(startloc[1])
   write_coord(startloc[2]) 
   write_long(500) 
   write_byte(5) 
   message_end() 
}

ent should be ID i guess

hehe right, too quick with posting

You can also use this:

 
  new OriginA[3]
  new OriginB[3]
  new players[32], inum
  new Radius = 100.0
  for(new i = 0 ;i < inum; ++i)
  {
    get_user_origin(players[i],OriginB)
    if(get_distance(OriginA,OriginB) < Radius && players[i]!=id)
    {
     explosion(players[i])
    }
  }

You would need a traceline only if you want to detect a "visible" players. If visiblity doesn't matter you can just check the players' distance or just use find_ent_in_sphere.

Here without origin,but it need engine module
This set every player who is in radius in the array to 1,and the rest to 0

new maxplayers = get_maxplayers()
new players[32]
new Float:Radius = 100.0
for(new i = 1 ;i < maxplayers ; ++i)
{
       if(entity_range(id,i) < Radius && players[i]!=id && is_user_connected(i))
          players[i] = 1
       else players[i] = 0
}

or with "get_entity_distance(ent1, ent2)" that return a non float value,but is the same.

and what i have to change if they have to be on the left or right side from me ?

so practically close to the same x axis

[schnitzelmaker]

for this you need the player origin

new OriginA[3] // [0]=x,[1]=y,[2]=z
new OriginB[3]
new players[33]
new maxplayers = get_maxplayers()
new Float:Radius = 100.0
new FLoat:MaxXdifference = 10.0 //this is how big can be the difference in "x"
// as example your origin is 350.0,so the playerorigin can be 350.0 +/-10.0
get_user_origin(id,OriginA) 
for(new i = 1 ;i < maxplayers ; ++i)
{
    get_user_origin(i,OriginB)
    if(get_distance(OriginA,OriginB) < Radius && i != id && is_user_connected(i))
    {
      //i use a second if to explain,but it can also used both in 1 if
      if (OriginB[0] <= (OriginA[0]+MaxXdifference) && OriginB[0] >= (OriginA[0]-MaxXdifference))
          players[i] = 1
      else players[i] = 0
    }
}

I don't think that'll work, since the origin[0] always changes.

??? origin is not an fix number,its dynamic.

with get_user_origin(id,OriginA) it get own origin.
with get_user_origin(i,OriginB) it get the playerorigin

And the example was only for 1 time for 1 second,its not the fully plugin.
