AlliedModders - [ZP] Little help in editing additional plugin.

Hello.

Long time ago Mercylezz (zombie plague coder) did this plugin. Since he hasnt been seen for half a year now I'm writing here. It just adds additional zombies to each simple infection round (not multi-infection round!). Now here's a problem: it makes static ammount of players to turn into zombies. I'd like to ask if anyone could make it so this plugin would add additional zombies in % depending on players count currently on server, like some ratio or whatever (for example zp_bonus_zombies 0.2 -> 20% of players are becoming additional zombies).

Do not tell me about multiple infection, it's completely different thing.

Thank you.

UPD: Oh yeah, I forgot: it would be cool to have also some kind of a minimum players required for this plugin to work. Like if current players count is less than X, then plugin will do nothing.

PHP Code:


		
			
#include <amxmodx>
#include <zombieplague>

new g_maxplayers, cvar_additionalzombies

public plugin_init()
{
    register_plugin("[ZP] Multi Infection", "0.1", "MeRcyLeZZ")
    
    g_maxplayers = get_maxplayers()
    
    // How many additional players should be infected at start
    cvar_additionalzombies = register_cvar("zp_additional_zombies", "1")
}

public zp_round_started(gamemode)
{
    // Normal infection modes only
    if (gamemode != MODE_INFECTION)
        return;
    
    // Figure out how many players should we infect (one human should be left alive!)
    new id, iZombies, iMaxZombies = min(get_pcvar_num(cvar_additionalzombies), fnGetAlive()-2)
    
    // Randomly turn iMaxZombies players into zombies
    while (iZombies < iMaxZombies)
    {
        // Keep looping through all players
        if (++id > g_maxplayers) id = 1
        
        // Dead or already a zombie
        if (!is_user_alive(id) || zp_get_user_zombie(id))
            continue;
        
        // Random chance
        if (random_num(0, 10) == 0)
        {
            // Turn into a zombie
            zp_infect_user(id)
            iZombies++
        }
    }
}

// Returns alive players count
fnGetAlive()
{
    new iAlive, id
    
    for (id = 1; id <= g_maxplayers; id++)
    {
        if (is_user_alive(id))
            iAlive++
    }
    
    return iAlive;
}
