Check if player is in radius of entity?

How can I check to see if any player is in the radius of any info_* entities?

find_ent_in_sphere()

I'm a bit confused on how to use find_ent_in_sphere(). I really don't even know how to set the function up to work.

I just need to find if any info_* entities are in the radius of a players id. If there are any info items then it can say... "Found info entity".

Code:

new ent;

ent = -1
while((ent = find_ent_in_sphere(ent, ?,?)))
{
    // Now what?
}

Fakemeta !?

Code:

#include <fakemeta>

new Float:radius = 300.0;
new ent = -1;

    while((ent = engfunc(EngFunc_FindEntityInSphere, ent, PlayerOrigin, radius)) != 0)
    {
        pev(ent, pev_classname, entclass, 32)
        if(contain(entclass, "info_") != 0)
        {
             // found entity ;)
        }
    }

This should be the engine I'm assuming...

Code:

#include <engine>

new Float:radius = 300.0;
new ent = -1;
new entClass[32];

while((ent = find_ent_in_sphere(ent, forigin, radius)) != 0)
{
    entity_get_string(ent, EV_SZ_classname, entClass, 31);
    if(contain(entClass, "info_") != 0)
    {
        // found entity ;)
    }
}

When trying to compile I get a tag mismatch on this line...
entity_get_string(ent, EV_SZ_classname, entClass, 31);

Also, should this line be a 0 or -1 at the end...?
while((ent = find_ent_in_sphere(ent, forigin, radius)) != 0)

Why not using fakemeta?
pev(ent, pev_classname, entClass, 31) works fine ;)
But the engine way you posted looks correct too..0o

It should be 0 ;)

Hmm, I'm not sure why I get the tag mismatch then.

I'm trying to use engine too because the rest of my code is in engine.
