bit(bit)
PRIVATE - Converts a bit in a value, for the functions.
Example: bit(2) is 4 and bit(3) is 8.

setBit(var, slot)
Sets the bit 'slot' (from 0 to 31) of a var to true.

unsetBit(var, slot)
Sets the bit 'slot' (from 0 to 31) of a var to false.

getBit(var, slot)
Returns the bit 'slot' (from 0 to 31) of a var.

setAllBits(var)
Sets all bits of a var to true.

unsetAllBits
Sets all bits of a var to false.


Example:

Код:

enum 
{
    Connected,
    Logged,
    Spawned,
    Dead      
}

new 
    pBools[MAX_PLAYERS];

OnPlayerDeath(playerid, killerid, reason)
{
    unsetBit(pBools[playerid], Spawned);
    setBit(pBools[playerid], Dead);
    return 1;
}

OnPlayerRequestSpawn(playerid)
{
    if(!getBit(pBools[playerid], Logged)) return 0;
    return 1;
}

OnPlayerSpawn(playerid)
{
    if(getBit(pBools[playerid], Dead))
    {
        SendClientMessage(playerid, COLOR_WHITE, "You was dead");
        unsetBit(pBools[playerid], Dead);  
    }
    setBit(pBools[playerid], Spawned);
    return 1;
}

OnPlayerConnect(playerid)
{
    setBit(pBools[playerid], Connected);
    return 1;
}

OnPlayerDisconnect(playerid, reason)
{
    unsetAllBits(pBools[playerid]);
    return 1;
}

encodeBits({Bool:}...)
Returns a set of bit of values "bools". It's like encode_tires or encode_lights, so it's "universal"...

Example:

Код:

new 
    panels, 
    doors, 
    lights, 
    tires;       
GetVehicleDamageStatus(vehicleid, panels, doors, lights, tires);
UpdateVehicleDamageStatus(vehicleid, panels, doors, lights, encodeBits(true, true, false, true));
