I have an entity object that follows another object. By default, it chooses its owner
I want to run an entity search cycle in a radius by class. find_sphere_class()
it seems to me that I should use do / while-cycles or for-cycles
But I can find the correct syntax for using them. Send me some tutorial or help.

The task is as follows:
I create an NPC dog that runs after me.
If it finds another player from the enemy team in the radius, then dog should run to him and bite him to death.
Dead player will drop weaponbox, a dog takes it in her teeth and carries it to me.
but if a player is found again along the way, then dog drops the weaponbox and runs to attack.

find_sphere_class will store the entities, if any, in the entlist array you pass in, similar to get_players.

CoolFunction(dog)
{
    new entityList[20]
    const Float:radius = 300.0
    new numberOfEntities = find_sphere_class(dog, "weaponbox", radius, entityList, sizeof entityList)

    if (numberOfEntities > 0)
    {
        // Found that many weaponboxes near the dog

        // If you need to get the closest one, sort the array
        new data[1]
        data[0] = dog
        SortCustom1D(entityList, numberOfEntities, "SortByShortestDistance")

        // Finally, get a single weaponbox to work with
        new weaponbox = entityList[0]

        // Do something here
        DogMoveToTarget(dog, weaponbox)
    }
}

public SortByShortestDistance(elem1, elem2, const array[], const data[], data_size)
{
    new dog = data[0]
    new Float:distanceToFirstOne = entity_range(dog, elem1)
    new Float:distanceToSecondOne = entity_range(dog, elem2)

    if (distanceToFirstOne < distanceToSecondOne)
    {
        return -1
    }

    if (distanceToFirstOne > distanceToSecondOne)
    {
        return 1
    }

    return 0
}
