Hi.

I'm a little bit confused

new origin[3]
    get_user_origin(id, origin, 0)
    new ent = -1
    ent = find_ent_in_sphere(ent,origin,50.0)

So basically "ent" here

 ent = find_ent_in_sphere(ent

means that we're searching for "ent" in a sphere whose radius is equal to 50?
Also, please what does this mean and why do we even have to make it "-1"

new ent = -1

According to the documentation, the first argument is what entity index to start from for the search. So, setting it to -1 tells it to search all entities.

The last parameter is the origin to search around so you could set ent = -1 and instead do a search around an origin, not around an entity.

Huh, what? I don't think anything in that statement is true.

[Natsheh]

Basically this function will iterates entity by entity depending on the given start position corresponding to the entity index will search entities distance and return the first entity that's in range.


Actually setting ent to -1 telling it to start the search from 0 which is worldspawn default entity id

If there are no entities nearby the radius it will return 0 on failure

hes thinking of find_sphere_class() which is better to use in most cases

OP what are you trying to do exactly?

Thanks alot to all of you! much appreciated guys

That's exactly the thing that confuses me, what does "start from" mean? Does it mean that we are searching for it?

Ah, that makes sense, so for example, when we set "-1", we can set a "ct player" as an origin and search around him for a "Terrorist" player?

If you're looking for real players within a radius you'd better just loop through all alive players with get_players and check the distance between the "center" of the sphere, origin in your case and the player current position. Off the top of my head:

new players[32], count
get_players(players, count, "ah")

new Float:sphere_center_pos[3]
new Float:sphere_radius

for (new i = 0, player, Float:pos[3]; i < count; i++)
{
    player = players[i]
    entity_get_vector(player, EV_VEC_origin, pos)

    if (get_distance_f(sphere_center_pos, pos) > sphere_radius)
        continue

    // player is within the radius, do something
}
